My rooted Nook Color, running Stock 1.4.2, and CM9 AOKP from an SD Card, had working WiFi for about a month or so. And just suddenly, it stopped working. I tried to Factory Reset the Stock ROM to see if that would do anything, but it didn't. Now whenever I try to re-register my Nook, it can't even connect to my home network. I also tried the same with my bootable SD Card, but still nothing. How would I fix this?
