My wifi is the same....shut off and turn back on for it to work...very irritating. Needed for different networks.... so I know it is the phone. Otherwise, great phone.
I had to schedule my Belkin router to restart frequently...no problems now. Hit 22-23 Mbps down all the time now.....was sporadic with my Infuse before that.
I have only had mine for a month and really like it. I did watch the forums for months before getting it. I agree it seems like a wonderful, but neglected phone.
