After updating my phone to the recent Android Lollipop 5.0.1, I have had WIFI issues. After testing multiple settings on my phone and multiple routers, I have found that turning off mobile data in the phones settings allows me to use my WIFI flawless. Kind of really annoying but I’m glad I have a working solution to cut down on my data usage through my phone carrier.

I can actually leave Mobile Data on, just turn off/uncheck the 4GLTE option and WIFI will still work.
