Firstly sorry for the generic 'can't connect to the internet' post.
I'm currently sat on my dads laptop, which is connected to the wireless network fine. However, mine will not.
It finds the router ok, and even says that is connected to the internet (the symbol in the tray bottom left shows 2 screens and a world) but i'm getting Internet Explorer cannot be displayed.
When I run the diagnostic, it is saying 'Cannot communicate with http://www.microsoft.com
- network diagnostics pinged the remote host but did not recieve a response'.
It gives me the option to resent the Wireless Network Adaptor, but i've tried this and it doesn't help.
I've also completely shut down and rebooted my laptop and the router several times.
I'm running Windows Vista and my laptop is a HP Pavillion dv5.
I'm fresh out of ideas and i've got essays to write...
If someone is feeling benevolent and could offer some help or advice, i would be eternally grateful.
