My husband and I have the same problem on both our newer EVO's. Got phones in early June, my WiFi would connect at home, and disconnect immediately. It happened on our home network, several of our friends and even at the Sprint store when we took it in. After doing several resets etc, they decided to give us new phones. Three weeks later, it happened again. Took them back in, several resets etc and even downloading the upgrade at Sprint, phones worked less than a week. We're taking them back in this PM. Maybe they'll come up with a new solution. I am getting tired of having to download and reinstall all my APPs. Anyone have other solutions?
