Hi guys n gals,
Just moved back home for christmas and we've moved house. This means I cant plug my pc into the router directly since there is broadband socket in my room

! We've set up the broadband and it all works, using BT Home hub v1.5 with BT Broadband unlimited. All the other laptops work wirelessly on the network including my dads desktop (connected wireless via a linksys wireless usb adapter).
So I come home today, and go out and buy a USB adapter so I can connect wirelessly to the nextwork. I bought a Belkin F6D4050 N150 Enhanced Wireless USB Network Adapter since it was a good price and I trust Belkin.
Get back home, insert the disc. It goes through the install and finishes. I restart my pc plug in the usb adapter and well, it doesnt work. Look in device manager and aparently my device is not recongised (aka the cd didnt install anything!). I install the drivers manually searching in the disc and it seems like it works. Connect to my wireless network and everything goes ok, all systems go i thought!
I have a good steady 3 bars of signal, but it seems I cant connect to most internet applications apart from Skype (weird?) all my browsers say 'page cannot be found etc'. So I right click my wireless device and click troubleshoot. It goes through it all and reports 'The DNS server isn't responding' 'Your computer is trying to use a DNS server that is incorrect or doesn't exist'. Weird eh?
Next thing I do is to update drivers, tried that and it did nothing, rubbish. Still doesnt work! Restarted the router as well, restarted my pc. Nothing works

! I also tried to get to my admin page (192.168.1.254) but says page cannot be displayed again.
Just to repeat, this is only on my desktop with this usb adapter. My nc10 netbook works fine

!
Please take a look, any help will be amazing!!
