I have connected to the access point in the Client mode, but cannot establish link connections with other wireless devices.

Connect this unit and the wireless devices to the same access point.
*If connection of this unit to the access point you are trying to connect to fails, this unit is automatically connected to a previously connected access point in the connection history.
*The SSID of the access point this unit is connected to can be checked at UTILITY -> WLAN INFORMATION -> SSID.
