Well I discovered that I have these issues when I connect to my wireless n dlink router at home and my jobs router (not sure what kind of router).. However when connecting to my mother and sisters wifi routers who have Verizon fios I never get disconnects from wifi when phone is out to sleep. Also when I connect to my mother in laws dsl router I think it's a westell Verizon router it also works fine..
S I think it's just not compatible with a lot of common routers.. I might buy a new router for my home to resolve the issue.
