i'm having the same issue. i posted a thread about it yesterday and didn't get any replies. i noticed the problem with airdroid, and used my og droid with it and it worked flawlessly, so i figured i got a dud with bad wifi. i just went and exchanged it. brought it home and i'm still having issues. maybe it's something with the router/connection or gnex wifi signal strength.

 

First day of phone, I came out of the house where I had wifi enabled, turned it off...had no data all day. VZW tech couldn't fix it. The other day I had no data at all...last night into this morning wifi basically blinked, on...off every 30 seconds. Had to pull teeth to get a new phone shipped Certain it won't help things. Phone should never have been released, its an abysmal failure. Something is wrong and they cannot fix it. Poor service and this is from the SF are.
