I can't really say when this started as I have never used WiFil much. But I have pretty weak data signal in my office so I finally got around to hooking my Bionic up to the wireless. The issue is when I leave the office and head home. No matter how I do it I have to fight to get back on VZ's network for data. It is all the usual symptoms of the old 'data drop'. Airplane mode won't fix it, I have to toggle CMDA/LTE to get it to reconnect. Does not matter if I turn WiFi off as I leave, or if I leave it on.
