Here is what is happening. Go to Settings > Wireless & Network Settings > Wi-Fi Settings > Menu Button > Advanced > Wi-Fi Sleep policy. I have it set to Never, but for some reason when the phone goes to sleep, it still uses 3g (mobile data). It used to work perfectly, but not anymore. When I wake up the phone, it takes a few seconds for the wifi icon to come back (also can check myverizon to verify that data is occuring when I'm within my wifi area). I just noticed this the other day and can't find a reason as to why it quit working. This is also happening on the wifes Droid X. Both are the OTA 2.2, mine is rooted, her's is not. Any ideas?
