Re: windows cannot open webpage
make sure the homepage is correct,
also try going to the internet options and make sure theres no proxies being used (unless its a work or uni network then you may be using one),
and are you obtaining the ip automatically? if you get the settings wrong then it may say its connected, but wont load a webpage/network.
