soon after i got the 4.3 OTA this notification pops up and then my wifi connection automatically disconnects from the phone and it dumps to 3G. clicking it in the shade pops up a dialog saying 'your internet connection is unstable blah blah' and mentions this auto switching feature. i went into advanced wifi settings and it's unchecked. but this thing pops up and disables my wifi internet each time. my PowerBook G4, iPhone, Galaxy Tab, and even this phone worked perfectly fine until the OTA. what is tripping this obviously incorrect notice?
