Why wi-fi connection is not established on Samsung Galaxy 511?
Hi. I have purchased Samsung galaxy 511 mobile and I am understanding its features and functions. But there is problem with wi-fi connection. When I try to connect with dsl modem (router), it catches signals of modem but ask security key every time. I have entered security key as given on modem but mobile still not connect with it. I have also checked and changed wi-fi connection of mobile but no understand what to do. Please help what should be done.
