I can connect to wifi no problem, but when I click on browser, it wont load, but when I look at the wifi signal I have all the bars. I recently stopped all data usage so I didn't accidentally use it, and since then my wifi has not worked. I've tried shutting my phone off and turning off my connection to wifi and turning it back on, but still no dice. It has only worked a couple of times, but recently not at all. Any help?
