It is rather frustrating, yesterday my WiFi was working just fine on my phone and today it's acting strange, I have a home router and it always connected flawlessly before but for some reason it won't connect, it'll show full wifi signal but if I click connect it shows it trying to connect and then it changes to not being accessible. I tried editing my settings on my phone, and my network key would always already be there in but in **** this format, but when I go and look it's not there at all I know the key so I enter it in (it shows as regular numbers and letters) but then it says it's not a valid network key, and it only lets me continue if I check the box that says "the key is automatically provided" and then magically with the same key it allows it and after getting past that page and returning to the screen which lists other connectible points, it shows it trying to connect then it changes from having full wifi signal strength to not being able to connect at all. It's really really really annoying can anyone help?
