Hello everybody! I have Samsung Galaxy 3 and I am experiencing an annoying problem with its Wi-Fi. Whenever I try to connect to certain networks it shows "Connecting..." and then after a few seconds "Disconnected". Then it goes through the loop again. It doesn't even start obtaining IP address! Please help me because one of those certain networks where that happens is at my home. I really hate going to Wi-Fi caffees and buying a drink just to download apps.
