I have a SGH-I537 with 5.0.1. Lately, I noticed that even though the Wifi Connection is on, pages time out constantly. There are brief moments where the connection is good and can access pages, but most of the time it just doesn't work. I can ping to and from my laptop and phone without any missing packets. It authenticates fine with the AP, but can't access any page, even by IP address. Thinking that maybe the firmware was at fault, I reflashed to OC7, but it is still behaving the same. Is it possible that the WiFi radio is dying?
