I have a TX-P42G20 which, for the past three months, I've had linked by cable to an Ethernet switch. I've been trying to get it to work with a new D-Link GWA-140 wireless adapter, but attempting to access the menu to configure the wireless side rather than wired brings up the message No Adapter even though it's inserted into one of the USB ports.
Has anyone else had this problem?
One possible point is that I'm now using the third router in line since acquiring the Panny at the end of March, but the network configuration didn't need to be changed to use with an Ethernet cable.
