I've got this Nook Color running Cyanogen 7, which @Thrax
put together for me.
Last Friday morning, it inexplicably stopped detecting any wi-fi networks. It's not just not connecting, it cant even see
any networks. When I'm at home it was only ever able to connect to the one in my house, but it could still see about ten other networks in my neighborhood. Now it can see zero (and all the saved ones say "not in range"), same when I'm at work.
I checked all the settings, unless there is a place I don't know to check (the Wi-fi options under 'wireless & networking' are all set properly. 'Background data' under 'accounts & sync' is also still active).
I didn't change any other settings or install any new software at the time it stopped working.
Googling hasn't helped, and otherwise I don't know where to begin troubleshooting this issue.
