Communication device

A non-transitory computer-readable recording medium storing computer-readable instructions for a communication device,

• wherein the computer-readable instructions, when executed by a processor of the communication device, causing the communication device to:
• perform a predetermined communication using a first type communication link via a wireless interface with a target device being a first type device in a case where the first type communication link via the wireless interface is established between the communication device and the target device, the wireless interface being configured to perform a wireless communication according to a predetermined standard, and the first type communication link being for the communication device to operate in a first mode defined by the predetermined standard;
• determine, by using attribute information included in a specific signal that is received from the target device for establishing a second type communication link, which of the first type device or a second type device the target device is, in a case where the second type communication link via the wireless interface is established between the communication device and the target device, the second type communication link being for the communication device to operate in a second mode different from the first mode and defined by the predetermined standard;
• execute an authentication of the target device being the second type device by using identification information included in the specific signal in a case where it is determined that the target device is the second type device;
• disconnect the second type communication link without executing an authentication of the target device in a case where it is determined that the target device is the first type device;
• and
• perform the predetermined communication using the first type communication link via the wireless interface with the target device being the first type device in a case where the first type communication link via the wireless interface is established between the communication device and the target device being the first type device after the second type communication link has been disconnected due to the determining that the target device is the first type device.

A method performed by a communication device, the method comprising:

• performing a predetermined communication using a first type communication link via a wireless interface with a target device being a first type device in a case where the first type communication link via the wireless interface is established between the communication device and the target device, the wireless interface being configured to perform a wireless communication according to a predetermined standard, and the first type communication link being for the communication device to operate in a first mode defined by the predetermined standard;
• determining, by using attribute information included in a specific signal that is received from the target device for establishing a second type communication link, which of the first type device or a second type device the target device is, in a case where the second type communication link via the wireless interface is established between the communication device and the target device, the second type communication link being for the communication device to operate in a second mode different from the first mode and defined by the predetermined standard;
• executing an authentication of the target device being the second type device by using identification information included in the specific signal in a case where it is determined that the target device is the second type device;
• disconnecting the second type communication link without executing an authentication of the target device in a case where it is determined that the target device is the first type device;
• and
• performing the predetermined communication using the first type communication link via the wireless interface with the target device being the first type device in a case where the first type communication link via the wireless interface is established between the communication device and the target device being the first type device after the second type communication link has been disconnected due to the determining that the target device is the first type device.
