after a lot of failed attempts at upgrading my computer to windows 8.1, i finally upgraded it. but when i first tried to connect to the internet after the upgrade, i could not for windows said the router is not compatible with the computer so it could not connect. i tried pinging on cmd after i somewhat successfully connected to the router and the pings could get through. i just dont know why my browsers just cannot connect to the internet, chrome keeps saying that the website is down or has moved and IE just gives me a connection problem, which i know is not possible
