I've had some luck then I purchased droid X on release day and haven't had any issues whats so ever with it. I'm connected to neighbors wifi here at work with a simple click. I've never had restarts other than from user error< oc/ulc and other stuff where I am to blame for the issues> at home i'm running through my uverse router/modem with no issues and ran just as good with my linksys. Did you possibly have any certain apps installed on the old phone that you might have installed on the new phone prior to any issues? Sucks your having these issues hopefully they get resolved.
