Sony Blu-ray lost WiFi?

[nikolasmason]

I had a strange issue with my Sony Blu-ray Google TV box last night. The last thing I had done on it was watch Investigation Discovery on cable. Then I left, turning off my Bravia TV (not the box). When I came back home later in the day, I turned on my Bravia, and the box was on Netflix, not live TV anymore, and the remote control wasn't working at all for the Google TV. The only thing I could do was change the volume or turn my bravia on or off. After a few minutes, I got it working again by turning off the box itself. But now that it is working again, the Wifi doesn't work. When I go into the settings, it just says 'Error', and won't connect at all.

Any ideas what could cause that? Or how to fix it?
