Have had my Maxx for less than three days and have noticed this quirk about the phone. The house wifi drops after 30 min of activity. I have downloaded and activated the connectivities patch that has been suggested in another thread, issue still there. When I go to the Settings screen/wi-fi, the screen states that I am connected to the house wifi. On the phone screen the wifi indicator is no longer blue, it is white/gray.
My wife as Razr as well, non-maxx or anything else and her wifi connection is solid and doesn't drop, EVER! So the problem isn't the house wireless, it is something in the phone.
I have done the google thing, tried the recommended solutions, no luck on any of them.
Looking to the collective for a solution before going into the store and demanding a replacement and stepping back to the regular razr.
