I too had the same issue with my Panasonic TC-P58VT25 when I switched from Comcast internet service to Verizon Fios. It could not connect to the server, and could not read the IP address of the router. Both Panasonic and Verizon were no help in addressing the problem with connection to VieraCast. I thought it may be an issue with the Panasonic wireless adapter?? Eventually, I decided to use the adapter through the Panasonic Blu-Ray player, and that worked--not sure why it is working this way, and not through the TV??
