I've had this phone for about a month now. I love it, but the wifi seems to be having trouble staying on. It's done this to me a few times already, but usually a reboot would fix it. For the past 4 days, the wifi hasn't worked. Every time I go to the wifi settings, it just says "turning wifi on". It never comes back on though. I already uninstalled the at&t smart wifi app a few weeks ago, as I've seen many posts that mention that it can cause problems. Is there anything else I should try?
