I have a Samsung Galaxy S2 SPH710, and I'm trying to figure out why the wifi periodically works or stops receiving the signal at times. When I'm on chrome and using my wifi, sometimes the page doesn't load and its just a continuous loading bar. Its aggravating especially when your on an app and then you have to turn off your wifi and back on. Same for apps like facebook and kik. Any way to get the full/undisrupted signal from my router?
