Checked everything I could think of including my router settings trying to get my WIFI back. Finally went in to settings and unchecked the DLNA, and KMA, WIFI is working again. Still can't my Google contacts to sync up though everything else will. Called Sprint about a different issue, and after demanding to speak to upper level tech, was told the Sprint stores have a program called "mobile sync" that backs up and restores all your apps after they do a hard reset. Told him I'd been in Sprint stores all over the country, and their answer to any issue is "Do a hard reset". When I asked if they were going to backup and restore all my downloaded apps after, every last one had the same answer:"Oh no, you have to do that". He said he was distressed to hear that as that's part of them doing a hard reset. Told him their stores must not have gotten that memo! I'm going into a Sprint store after Christmas, and demand a hard reset, a fresh install of Jelly Bean, and all my downloads restored! Sorry for such a long reply, guys. Thanks again for the DLNA tip - restored my WIFI at least!
