Hello, last night in morning my wifi on my HTC Rezound was working perfectly. However, after coming back from school my wifi suddenly stopped working. I tried to solve the problem by turning on and off my phone and then connecting to wifi, but still didn't work. I also tried turning off my router then connect to wifi again. All my other devices at home wifi works perfectly, but it's just my phone that just happened suddenly. Whenever it's trying to obtain ip adress from the network it will fail to connect every single time. Please help!
