I have not gone over 500MB in about two years. There's wifi at work, school & home. But this weak wifi needs to be fix ASAP. I tried 6.1 beta and there's no fix. If anyone knows a fix please tell me. It's really bad. When I say my grandmother has full bars in the kitchen on her iPhone 4S on 5.1 I will have no bars while being next to her. It'll say LTE.
