I'm stock rooted and last few days wifi has been refusing to act right. Yesterday I pulled down notifications and hit it..... nothing... then went the settings route and when I slide it from off to on it goes right back to off. Did that a dozen times gave up and went to bed. Forgot to charge it and it died overnight. Powered it on and low and behold the wifi was on and connected. I leave for work and turn the wifi off. Come back tonight and try to turn it on... same **it. Anyone have any suggestions?
