I just bought a Phone here yesterday running with Android ICS, the first time I used the wifi was ok, no problem. But now, the wifi is not working sometimes even I have a strong wifi connection. My PC, and my phone are on the same network. My PC is reading Full signal strength, as I am literally 5 feet from the wireless router. My phone is showing NO blue. Wifi meter is grey even if I have excellent connection, If it is blue, I can use my internet, but when it is grey I can't use my internet. I have the blue wifi around 20% of the time. What should I do?
wifi not blue means net cannot connect with google server! if u have rooted ur device just go to etc>hosts.bak using root explorer just add a '#' before the ip at the bottom line. Hope this will resolve ur issue works 99% with evry1! or try that on the first line ip!
