I can't seem to get my home wifi to work. It used to work, but will not connect any longer. I have the wifi turned on. My network is saved, secured and the password is correct (I triple checked). Signal strength is excellent. My security is, has been always WEP. When I click connect..... nothing happens. The icon on top does not show it connected, and when I go to an app, the 4G arrows are working. NO WIFI HELP!
