  In S15, the CPU 106 monitors whether the communication terminal device 100 is touched by an external device (for example, the MFP 51, 52, AP 501, 502). Specifically, the NFC communication I / F 112 provided in the communication terminal device 100 repeatedly outputs a polling signal at predetermined time intervals and monitors a response signal which is a response to the polling signal. On the other hand, the NFC communication I / F of the external device monitors the polling signal and outputs a response signal on condition that the polling signal is received.

And get. The connection information includes an SSID (hereinafter referred to as “SSID (WFD)”) and a password (hereinafter referred to as “password (WFD)”) for identifying the WFD network formed by the external device. Note that, for example, if the external device is not set to permit Internet connection, the permission information is not acquired. The permission information is set in the MFP in advance by the administrator or the like. Further, when the external device is establishing the infrastructure communication with the AP, the CPU 106 further acquires the SSID (AP) and the password (AP) corresponding to the connection destination AP.

  In S35, the CPU 106 causes the position sensor 101 to acquire the GPS information of the communication terminal device 100 at the time when the NFC communication with the external device is established, and acquires the GPS information from the position sensor 101. When the NFC communication is established, the distance between the communication terminal device 100 and the external device is about 10 cm at the maximum, and therefore the position represented by the GPS information is substantially equal to the position of the external device.

  In S40, the CPU 106 determines whether or not all external devices that should acquire various information have been touched. Specifically, CPU 106 determines whether or not a predetermined period has elapsed since the external device was last touched. More specifically, the CPU 106 detects that the NFC communication I / F 112 of the external device is not detected for a predetermined period from the time when the NFC communication I / F 112 last detected the NFC communication I / F of the external device. When is passed, YES is determined in S40 and the process of FIG. 2 is ended.

When the CPU 106 determines that the target device is permitted to connect to the Internet and there is an AP connected to the Internet (YES in S415), the process proceeds to S420. On the other hand, when CPU 106 determines that the target device is not permitted to connect to the Internet (NO in S415), CPU 106 skips S420 and proceeds to S425. Further, the CPU 106 determines NO in S415 even when the target apparatus is permitted to connect to the Internet and there is no AP connected to the Internet. The CPU 106 determines NO in S415 even when the permission information is not acquired from the target device in S20.

  In S420, the CPU 106 causes the broken line connecting the one or more AP images corresponding to the one or more APs determined to be connected to the Internet and the external device image corresponding to the target device to be a network screen. To display. The dashed line encourages establishing infrastructure communication between any of the one or more APs above and the target device. That is, when the target device is permitted to connect to the Internet, the AP image corresponding to the AP connected to the Internet is displayed more emphasized than the AP image corresponding to the AP not connected to the Internet. Can be said.

  In S425, the CPU 106 connects to the Internet for one or more APs that are prohibited (that is, not permitted) to connect to the target device on the Internet and are sources of various information in S20 of FIG. It is determined whether there is an AP that is not present. First, the CPU 106 determines whether the target device is prohibited from connecting to the Internet based on the permission information acquired in S20. When the CPU 106 determines that the target apparatus is prohibited from connecting to the Internet and there is an AP that is not connected to the Internet (YES in S425), the CPU 106 proceeds to S430. On the other hand, when CPU 106 determines that the target device is not prohibited from connecting to the Internet (NO in S425), CPU 106 ends the process of FIG. Further, the CPU 106 determines NO in S425 even if the target device is prohibited from connecting to the Internet and there is no AP that is not connected to the Internet. The CPU 106 determines NO in S425 even when the permission information is not acquired from the target device in S20.

  In step S430, the CPU 106 causes the broken line connecting each of the one or more AP images corresponding to the one or more AP determined not to be connected to the Internet and the external device image corresponding to the target device to be a network screen. To display. The dashed line encourages establishing infrastructure communication between any of the one or more APs above and the target device. That is, when the target device is not permitted to connect to the Internet, the AP image corresponding to the AP not connected to the Internet is displayed more emphasized than the AP image corresponding to the AP connected to the Internet. Can be said. When S430 ends, the process of FIG. 4 ends.

<Connection change processing>
The connection changing process executed by the CPU 106 of the communication terminal device 100 will be described with reference to the flow of FIG. The flow of FIG. 5 starts when the network screen display process of FIG. 3 ends.

  In S510, CPU 106 determines whether or not a connection operation has been accepted by touch panel 103 on the network screen. The connection operation is performed by an AP (hereinafter, referred to as “designated AP”) corresponding to one AP image included in the network screen and an external device other than the AP corresponding to one external device image (hereinafter, “designated device”). “)” Is an operation performed by the user on the touch panel 103 in order to establish infra-communication between them. Specifically, the connection operation is, for example, an operation of connecting one AP image and one external device image with a line. The touch panel 103 outputs the position information indicating the touched position to the CPU 106 when the connection operation is performed. CPU 106 determines that the connection operation has been accepted based on the position information input from touch panel 103. When CPU 106 determines that the connection operation has been accepted (YES in S510), the process proceeds to S513, and when it determines that the connection operation has not been accepted (NO in S510), the process proceeds to S530.

  In S513, the CPU 106 determines whether the connection operation accepted in S510 is a new connection operation or a switching operation. The new connection operation is an operation for establishing infrastructure communication between the designated AP and a designated device that is not connected to any AP. The switching operation is an operation for switching the communication destination of the infrastructure communication of the designated apparatus from the different AP to the designated AP when the AP different from the designated AP and the designated apparatus are establishing the infrastructure communication. .. When the designated device is not establishing the infrastructure communication with any of the APs (that is, when the SSID (AP) and the password (AP) have not been acquired from the designated device in S20 of FIG. 2), the CPU 106 accepts the connection operation accepted. Is a new connection operation, and the process proceeds to S514. On the other hand, when the designated device is establishing the infrastructure communication with any of the APs (that is, when the SSID (AP) and the password (AP) have already been acquired from the designated device), the CPU 106 accepts the accepted connection operation. It is determined that the operation is a switching operation, and the process proceeds to S521.

  In step S514, the CPU 106 executes communication of various signals using the SSID (WFD) and password (WFD) acquired from the designated device in step S20 of FIG. 2 to establish a wireless LAN_I / F 105 with the designated device. To establish WFD communication via.

  In S515, the CPU 106 transmits the SSID (AP), the password (AP), and the connection instruction, which have been acquired from the designated AP in S20 of FIG. 2, to the designated device via WFD communication. The connection instruction is an instruction for establishing infrastructure communication with the designated AP. When the designated device receives the SSID (AP), the password (AP), and the connection instruction from the communication terminal device 100, the designated device can perform communication of various signals and establish infrastructure communication with the designated AP. Note that the CPU 106 disconnects the WFD communication with the designated device after S515 ends.

  In S520, the CPU 106 displays a solid line connecting the AP image corresponding to the designated AP and the external device image corresponding to the designated device on the network screen. The solid line indicates that the infrastructure communication is established between the designated AP and the target device. When S520 ends, the process returns to S510.

  S521 is the same as S514. In S522, the CPU 106 transmits the SSID (AP), the password (AP), and the switching instruction, which have been acquired from the designated AP in S20 of FIG. 2, to the designated device via WFD communication. The switching instruction is an instruction for switching the communication destination of the infrastructure communication of the designated device from the AP in which the infrastructure communication is being established to the designated AP. When the designated device receives the SSID (AP), the password (AP), and the switching instruction from the communication terminal device 100, the designated device disconnects the infrastructure communication with the AP that is establishing the infrastructure communication, and further executes communication of various signals. Then, the infrastructure communication with the designated AP is established. Note that the CPU 106 disconnects the WFD communication with the designated device after S522 ends.

  In S524, the CPU 106 erases the solid line connecting the AP image corresponding to the AP that is the communication destination of the designated device and the external device image corresponding to the designated device from the network screen. S526 is the same as S520.

  In S530, CPU 106 determines whether or not a disconnection operation has been accepted by touch panel 103 on the network screen. The disconnection operation is an operation performed by the user on the touch panel 103 to disconnect the infrastructure communication between the designated AP and the designated device that is establishing the infrastructure communication with the designated AP. That is, the disconnection operation is an operation that can be executed when the infrastructure communication is being established between the designated AP and the designated device. Specifically, the disconnection operation is, for example, an operation of drawing a line that intersects with a solid line connecting one AP image and one external device image. The touch panel 103 outputs position information indicating the touched position to the CPU 106 when a disconnection operation is performed. The CPU 106 determines that the cutting operation has been accepted based on the position information input from the touch panel 103. If CPU 106 determines that the disconnection operation has been accepted (YES in S530), the process proceeds to S533, and if it determines that the connection operation has not been accepted (NO in S530), the process proceeds to S510.

  S533 is the same as S514. In S535, the CPU 106 transmits a disconnection instruction to the designated device via WFD communication. The disconnection instruction is an instruction for disconnecting the infrastructure communication with the designated AP. Upon receiving the SSID (AP), the password (AP), and the disconnection instruction from the communication terminal device 100, the designated device disconnects the infrastructure communication with the AP. Note that the CPU 106 disconnects the WFD communication with the designated device after S535 ends.

  In S540, the CPU 106 deletes the solid line connecting the AP image corresponding to the designated AP and the external device image corresponding to the designated device from the network screen. When S540 ends, the process returns to S510.

<Specific case>
Next, with reference to FIGS. 6 to 9, a specific case realized by executing the processes of FIGS. 2 to 5 will be described.

<Case A>
Case A of FIGS. 6 to 8 is a case where a new connection operation is executed on the network screen. In this case, the AP network formed by the first AP 501 is an in-house network. The AP network is not connected to the internet. The AP network formed by the second AP 502 is an external network. The AP network is connecting to the Internet. Further, the setting regarding permission for the Internet connection of the MFP 51 is not made. The MFP 51 is establishing infrastructure communication with the first AP 501. The distance between the MFP 51 and the first AP 501 is large, and the distance between the MFP 51 and the second AP 502 is small.

  When the application 121 is activated (YES in S10 of FIG. 2) and the first AP 501 is touched (YES in S15), the communication terminal device 100 establishes the NFC communication 151 with the first AP 501 (S17). Then, the communication terminal device 100 acquires the connection information including the SSID (AP) “XXX” and the password (AP) and the network information indicating the in-house network from the first AP 501 via the NFC communication 151 (S20). .. Furthermore, the communication terminal device 100 acquires the GPS information of the communication terminal device 100 (that is, the GPS information of the first AP 501) at the time when the NFC communication 151 with the first AP 501 is established (S35).

  When the communication terminal device 100 touches the second AP 502 (YES in S15 of FIG. 2), the NFC communication 152 with the second AP 502 is established (S17). Then, the communication terminal device 100 acquires the connection information including the SSID (AP) “YYY” and the password (AP) and the network information indicating the external network from the second AP 502 via the NFC communication 152 (S20). .. Further, the communication terminal device 100 acquires the GPS information of the communication terminal device 100 (that is, the GPS information of the second AP 502) at the time when the NFC communication 152 with the second AP 502 is established (S35).

  When the communication terminal device 100 touches the MFP 51 (YES in S15 of FIG. 2), the NFC communication 153 with the MFP 51 is established (S17). Then, the communication terminal device 100 acquires the connection information including the SSID (WFD) “AAA” and the password (WFD) from the MFP 51 via the NFC communication 153 (S20). Note that the permission information is not acquired because the MFP 51 has not been set to permit Internet connection. The communication terminal device 100 further acquires the SSID (AP) “XXX” and the password (AP) corresponding to the first AP 501 to which the MFP 51 is connected (S20). Further, the communication terminal device 100 acquires the SSID (AP) “XXX” and the radio field intensity “weak” corresponding to the first AP 501 from the peripheral AP (that is, the first AP 501), and another peripheral AP (that is, the second AP 502). From SSID (AP) "YYY" and the radio wave intensity "strong" corresponding to the second AP 502 are acquired from. Note that the radio wave intensity “weak” indicates that the radio wave intensity is less than the predetermined value, and the radio wave intensity “strong” indicates that the radio wave intensity is equal to or higher than the predetermined value. Further, the communication terminal device 100 acquires the GPS information of the communication terminal device 100 (that is, the GPS information of the MFP 51) at the time when the NFC communication 153 with the MFP 51 is established (S35).

  Next, the communication terminal device 100 displays the network screen 180 (S110 of FIG. 3). The network screen 180 includes a first AP image corresponding to the first AP 501, a second AP image corresponding to the second AP 502, and a first MFP image corresponding to the MFP 51. The first AP image is associated with SSID (AP) “XXX”, GPS information (that is, latitude and longitude), and network information (that is, in-house network). The SSID (AP) "YYY", GPS information, and network information (that is, an outside network) are associated with the second AP image. The SSID (WFD) “AAA”, GPS information, and SSID (AP) “XXX” are associated with the first MFP image.

  The communication terminal device 100 selects the MFP 51 (S115 in FIG. 3). The communication terminal apparatus 100 has already acquired the SSID (AP) “XXX” and the password (AP) from the MFP 51, and therefore determines that the MFP 51 is connected to the AP (YES in S120). Since the SSID “XXX” acquired from the MFP 51 matches the SSID “XXX” acquired from the first AP 501, the communication terminal apparatus 100 determines that the AP to which the MFP 51 is connected is the first AP 501 (YES in S125). ), A solid line connecting the first AP image and the first MFP image is displayed (S130).

  The communication terminal device 100 specifies the SSID (AP) “XXX” acquired from the peripheral AP that matches the SSID (AP) “XXX” acquired from the first AP 501, and acquires the SSID (AP) “XXX” at the same time. The specified radio wave intensity “weak” is specified (S305 in FIG. 4). In addition, the communication terminal device 100 identifies the SSID (AP) “YYY” acquired from the peripheral AP that matches the SSID (AP) “YYY” acquired from the second AP 502, and identifies the SSID (AP) “YYY”. The radio field intensity “strong” acquired at the same time is specified (S305). Then, the communication terminal device 100 displays the radio field intensity "weak" in association with the first AP image and displays the radio field intensity "strong" in association with the second AP image (S305).

  The communication terminal device 100 determines that the radio field intensity “strong” corresponding to the second AP 502 is equal to or greater than the predetermined value (YES in S310 of FIG. 4), and connects the second AP image and the first MFP image with a broken line (S315).

  The communication terminal device 100 determines that the first AP 501 is not connected to the Internet because the attempt to execute communication with the server on the Internet via the first AP 501 fails (S410 in FIG. 4). Further, the communication terminal apparatus 100 succeeds in the attempt to execute communication with the server on the Internet via the second AP 502, and thus determines that the first AP 501 is connected to the Internet (S410). The communication terminal device 100 displays the Internet connection status (that is, not connected to the Internet) in association with the first AP image, and displays the Internet connection status (that is, connected to the Internet) as the second AP image. It is displayed in association with each other (S413).

  The communication terminal device 100 has not acquired the permission information from the MFP 51, and thus determines NO in S415 and S425 of FIG. By executing the above processing, the network screen 180 of FIG. 6 is displayed (state A1).

  When the communication terminal device 100 receives a disconnection operation for disconnecting the infrastructure communication between the first AP 501 and the MFP 51 on the network screen of FIG. 6 (YES in S530 of FIG. 5), the WFD communication with the MFP 51 is established. (S533). Then, communication terminal apparatus 100 transmits a disconnection instruction to MFP 51 via WFD communication (S535), and erases the solid line connecting the first AP image and the first MFP image from the network screen (S540). As a result, the network screen 180 of FIG. 7 is displayed (state A2).

  When the communication terminal apparatus 100 receives a new connection operation for establishing the infrastructure communication between the second AP 502 and the MFP 51 on the network screen of FIG. 7 (YES in S510 of FIG. 5, new connection operation in S513), the MFP 51 Establishes WFD communication with (S514). Then, the communication terminal device 100 transmits the SSID (AP), the password (AP), and the connection instruction to the MFP 51 via the WFD communication (S515), and the solid line connecting the second AP image and the first MFP image is displayed on the network screen. It is displayed on 180 (S520). As a result, the network screen 180 of FIG. 8 is displayed (state A3).

<Effect of case A>
As a configuration different from the present embodiment, a configuration in which the SSID (AP) and password (AP) of each of a plurality of APs that are candidates for the connection destination of the MFP 51 are stored in the storage unit 109 of the communication terminal device 100 in advance ( Hereinafter, it will be referred to as a “comparative example”). In the comparative example, the communication terminal device 100 uses the above information stored in advance in the storage unit 109 in order to display the network screen. Therefore, the user causes the communication terminal device 100 to display a network screen by touching the communication terminal device 100 only on the MFP 51. That is, it is not assumed that the user touches the communication terminal device 100 on the AP. Therefore, for example, the following problems may occur.

  As a first problem, if the AP that the user wants to connect to is not included in the plurality of APs that are candidates for the connection destination, the communication terminal apparatus 100 determines that the AP corresponding to the AP. Images cannot be displayed on the network screen. Then, the communication terminal device 100 cannot transmit the SSID (AP) and password of the AP to the MFP 51. That is, the communication terminal device 100 cannot establish the infrastructure communication between the AP and the MFP 51.

  As a second problem, even if the AP that the user wants to connect to is included in the plurality of APs that are candidates for the connection destination, the user may not notice that. .. In particular, the problem is highly likely to occur for a user who has little knowledge about wireless communication.

  On the other hand, according to the case A of the present embodiment, the user causes the communication terminal device 100 to acquire the connection information by touching the communication terminal device 100 on the APs 501 and 502 (S20 in FIG. 2). That is, the communication terminal device 100 can acquire the connection information even if the connection information is not stored in advance. This can suppress the occurrence of the first problem described above. Further, since the user touches the APs 501 and 502, the user recognizes that the APs 501 and 502 are candidates for connection. This can suppress the occurrence of the second problem described above. Then, while the first AP image, the second AP image, and the first MFP image are displayed on the network screen, the disconnection operation and the connection operation are performed by the user, so that the infrastructure communication is performed between the second AP 502 and the MFP 51. Can be established. In this way, the infrastructure communication between the second AP 502 and the MFP 51 can be properly established.

  According to Case A, the communication terminal apparatus 100 displays the solid line indicating that the infrastructure communication is established between the first AP 501 and the MFP 51, since the infrastructure communication is established between the first AP 501 and the MFP 51. (S130 of FIG. 3). Thus, the user can know that the MFP 51 has established the infrastructure communication with the second AP 502 by looking at the solid line.

  According to Case A, the user can disconnect the infrastructure communication between the first AP 501 and the MFP 51 by executing the disconnection operation (S535 in FIG. 5).

  According to Case A, the user can know that the infrastructure communication between the first AP 501 and the MFP 51 has been disconnected by confirming that the solid line has been erased (S540 in FIG. 5).

  According to Case A, the user knows that the infrastructure communication is established between the second AP 502 and the MFP 51 by confirming that the solid line is displayed after executing the connection operation (S520 in FIG. 5). be able to.

  According to Case A, the user sees the GPS information corresponding to the first AP 501, the GPS information corresponding to the second AP 502, and the GPS information corresponding to the MFP 51 so that the second AP 502 of the first AP 501 and the second AP 502 is It can be known that it is located closer to the MFP 51. Accordingly, the user can determine that the second AP 502 of the first AP 501 and the second AP 502 should be the communication destination of the MFP 51.

  According to Case A, the user can know that it is difficult to perform the infrastructure communication between the MFP 51 and the first AP 501 by seeing the radio field intensity “weak” corresponding to the first AP 501. The user can know that the infra-communication communication is easily executed between the MFP 51 and the second AP 502 by looking at the radio field intensity “strong” corresponding to the second AP 502.

  According to Case A, the user can easily select the second AP 502 having higher radio field intensity as the communication destination of the terminal device by seeing that the second AP image is displayed more emphasized than the first AP image. You can

<Case B>
Case B of FIGS. 6 and 8 is a case where the switching operation is executed on the network screen. The process until the network screen 180 of FIG. 6 is displayed is the same as in case A (state B1).

  When the communication terminal apparatus 100 receives a switching operation for switching the communication destination of the infrastructure communication of the MFP 51 from the first AP 501 to the second AP 502 on the network screen of FIG. 6 (YES in S510 of FIG. 5, switching operation in S513 of FIG. 5). ), And establishes WFD communication with the MFP 51 (S521). Then, the communication terminal device 100 transmits the SSID (AP), the password (AP), and the switching instruction to the MFP 51 via the WFD communication (S522), and the solid line connecting the first AP image and the first MFP image is displayed on the network screen. (S524), and a solid line connecting the second AP image and the first MFP image is displayed on the network screen 180 (S526). As a result, the network screen 180 of FIG. 8 is displayed (state B2).

  In case B as well, as in case A, the user can select the APs 501 and 502 that are candidates for connection, so that the infrastructure communication between the second AP 502 and the MFP 51 can be appropriately established.

  According to Case B, the user can switch the communication destination of the infrastructure communication of the MFP 51 from the first AP 501 to the second AP 502 by executing the switching operation (S522 in FIG. 5).

  According to Case B, the user can know that the infrastructure communication is established between the second AP 502 and the MFP 51 by confirming that the solid line is displayed after executing the switching operation (FIG. 5). S526).

<Case C>
Case C in FIG. 9 is a case in which the AP to which the MFP 51 is connected is an AP (third AP 503) different from the information source AP (that is, the APs 501 and 502). APs 501 and 502 in this case are similar to APs 501 and 502 in case A, respectively. The MFP 52 in this case is not permitted to connect to the Internet. The MFP 52 is establishing infrastructure communication with the third AP 503. The distance between the MFP 52 and the first AP 501 is large, and the distance between the MFP 52 and the second AP 502 is also large.

  The communication terminal device 100 acquires various types of information from the APs 501 and 502, as in case A (S20 in FIG. 2). Then, the communication terminal device 100, via NFC communication, the connection information including the SSID (WFD) “BBB” and the password (WFD), and the permission information indicating that the Internet connection of the MFP 52 is permitted, the MFP 52. (S20). The communication terminal device 100 further acquires the SSID (AP) “ZZZ” and the password (AP) corresponding to the third AP 503 to which the MFP 52 is connected (S20). Furthermore, the communication terminal device 100 acquires the radio field intensities corresponding to the APs 501 and 502, as in case A. However, in this case, the radio field intensity acquired from the second AP is “weak”. Furthermore, the communication terminal device 100 acquires GPS information of the communication terminal device 100 (that is, GPS information of the MFP 52) at the time when NFC communication with the MFP 52 is established (S35).

  Next, the communication terminal device 100 displays the network screen 180 (S110 of FIG. 3). Network screen 180 includes a first AP image, a second AP image, and a second MFP image corresponding to MFP 52. The information associated with each of the first AP image and the second AP image is the same as in case A, except for the radio wave intensity “weak” corresponding to the second AP image. The SSID (WFD) “BBB”, GPS information, and SSID (AP) “ZZZ” are associated with the second MFP image.

  The communication terminal device 100 selects the MFP 52 (S115 in FIG. 3). Communication terminal apparatus 100 has already acquired the SSID (AP) “ZZZ” and the password (AP) from MFP 52, and therefore determines that MFP 51 is connected to the AP (YES in S120). Since the SSID “ZZZ” acquired from the MFP 51 does not match any SSID acquired from the APs 501 and 502 (NO in S125), the communication terminal apparatus 100 is the third AP corresponding to the third AP 503 different from the APs 501 and 502. The image is displayed (S135), and the solid line connecting the third AP image and the second MFP image is displayed (S137).

  Communication terminal apparatus 100 determines that the radio field intensity “weak” corresponding to APs 501 and 502 is less than a predetermined value (YES in S310 of FIG. 4). Further, the communication terminal device 100 displays the Internet connection status in association with the APs 501 and 502, as in case A.

  The communication terminal apparatus 100 displays the broken line connecting the first AP image and the second MFP image (YES in S425 of FIG. 4) because the Internet connection of the MFP 52 is prohibited and the first AP 501 is not connected to the Internet (YES in S425 of FIG. 4). S430). By executing the above processing, the network screen 180 of FIG. 9 is displayed (state C1). Note that the communication terminal device 100 can accept a disconnection operation or a switching operation on the network screen of FIG. 9. For example, when the communication terminal device 100 receives a switching operation for switching the communication destination of the infrastructure communication of the MFP 52 from the third AP 503 to the first AP 501 (YES in S510 in FIG. 5, switching operation in S513), the SSID (AP ), The password (AP), and the switching instruction are transmitted to the MFP 52 (S522).

  In case C as well, as in case A, the user can select the APs 501 and 502 that are candidates for the connection target, so that one of the first AP 501 and the second AP 502 and the MFP 52 can properly perform infrastructure communication. Can be established.

  According to Case C, the user can know that the infrastructure communication is established between the third AP 503 and the MFP 52 by looking at the solid line (S137 in FIG. 3).

  According to Case C, the user can know that the first AP 501 is connected to the Internet and the second AP 502 is not connected to the Internet by looking at the network screen 180 (S413 in FIG. 4). .. This allows the user to know which of the first AP 501 and the second AP 502 should be selected as the communication destination of the MFP 52.

  If the Internet connection of the MFP 52 is permitted in case C, a broken line connecting the second AP image and the second MFP image is displayed instead of the broken line connecting the first AP image and the second MFP image (see FIG. 4). S420). Therefore, when the MFP 52 is permitted to connect to the Internet, the user can easily select the second AP 502 connected to the Internet as the communication destination of the MFP 52.

  According to Case C, the user can easily select the first AP 501 not connected to the Internet as the communication destination of the MFP 52 when the MFP 52 is not permitted to connect to the Internet (S430 in FIG. 4).

  Specific examples of the present invention have been described above in detail, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. Modifications of the above embodiment are listed below.
