Ernie = he did say it is on WiFi. He did say other devices in the house are still working on WiFi.

Unplug the Bluray player for 10 minutes. Plug it back in. Then go thru the guided setup for internet again (as Ernie suggested). If the WiFi doesn't show up at all to connect to, then (as Ernie said) your WiFi in the Bluray maybe dead.
If you can get an ethernet cable to the bluray player, that could solve your problem - and would have been the better way to hook it up anyway.
If you can't get an ethernet cable to your bluray, go buy a new bluray player. It wasn't an expensive model anyway. Get the new Sony BDPS3700, it is only $80 on amazon.com
