I installed unofficial CM9 ROM on a spare Pico I had yesterday, and flashing and booting worked fine. In fact, I was able to use it for a good full hour. After that, I tried installing the unofficial CM11 ROM, but didn't quite like the UI compared to CM9. I wiped /system, /data, /cache, and even dalvik cache and flashed back to CM9. Wifi worked as soon as I was booted back into CM9, but about half an hour later, it decided to stop working. I went into Wifi settings and under my network, it said "Authentication problem". I also read that there were Wifi issues in CM9. Is this true? Also, is there a fix for this? Thanks for looking.
