Connected to network, full signal, but no inet!

[Wrighty]

Right so heres my story from the begining, I live in a pub and use a shared wireless network, for customers, in the evening its only me using it, i decided to build my own pc, with windows 7, ive put a tp-link wn851n, first plugged it in didnt work, i managed to connect to the router, nothing...would go on the page and say*site found, waiting for reply* and would do nothing more, so i unstalled the software took the card out put it back in, worked, like a dream for the last 4 days, so yesterday it starts doing the same thing, i come to turn the pc on *page found, waiting for reply* last 2 days its done that for now, and im getting very very irate, i took it out today put it back
In, still doesnt work, im currently writing to you on my
Iphone as proof its nothing to do with the router, my laptop also works, however that is windows xp, so it has me thinking, is it my OS? Or maybe a setting for the card? Or maybe the software? I need help, and quick, i have 10 days off work starting thursday, i will be pulling my hair out if i have no internet ! Thanks guys.

Wrighty.

Thanks for the ipconfig /all output, it looks good. Please try these suggestions:

Update your Wi-Fi card's driver to the latest.

Refresh and Remove all your wireless networks. Reconnect to your SSID, make sure that you type in the correct encryption.
