Shortly after I updated to 20140306 and the latest GAPPS the Wi-Fi stopped working. I would turn Wi-Fi on and see all my saved connections but none of the active access points around me. The Wi-Fi Analyzer app also shows nothing. But other android devices can see and connect ok.
I just updated to 20140309 and saw the access points for a few minutes but didn't connect, and now once again I don't see anything.
I tried booting to stock and from there I could connect so the Wi-Fi radio itself on the tablet is working OK.
I haven't changed any of the Wi-Fi settings on the tablet. Any suggestions much appreciated.
