Well, I have 12 devices currently using my wireless connection and I did not have to change any settings to get them to work. I think Panasonic has not done a very good job of integrating their software with existing wireless hardware. Standard wireless adaptors should work, but I have tried 2 that didnt. THe TV did not recognize the devices, not the router. However the TV recognizes the Panasonic brand wireless adaptor, but it doesnt connect to the router - it should be automatic once I enter the WEP key.
I am not happy with Panasonic.
