Wi-Fi Compatibility Issue?

Hi,

Wondered if anyone could give me some advice please. I have a wireless broadband package setup (Virgin Media) with a Netgear 54Mbps Wireless ADSL Modem Router (DG834GSP v3) which I can access through Wi-Fi on a laptop (running Vista Home). The network is secured with WPA-PSK.

I want to connect to the same network on another computer (desktop, running Win XP SP2) which has a Belkin Wireless USB Network Adapter (F5D7051) installed with the relevant drivers, however the Belkin Adapter can see the network as WPA-PSK and asks for a password which I enter, it then sits there trying to connect to it and in the end I get the message "Limited or No Connectivity".

Could someone please advise what I can do to connect to the network with this computer?

Many thanks in advance

Paul

Update

Hi,

I managed to get the wireless adapter connected, it seems I was using the wrong WPA password (doh!!).

However after it has connected (at 54Mbps with a 'very good' connection) I can't seem to access the internet or download any Anti-Virus updates. I checked the Wireless Network Connection Status and the Activity tab showed 1374 packets sent and only 120 received. I am running Comodo firewall and thought that may be causing problems, so I turned it off and turned Windows Firewall on but the same problem occured - no access to the internet. If I connect to the same router via a laptop I can connect to the internet no problems, so I know it must be a problem with the computer settings where the wireless adapter is connected to.

Does anyone have any further suggestions please?

Thanks

Paul
