Wireless network stopped working

Hi,

I have a belkin wireless router (failry new with the 2 antenna) , which I used to have my pcs wired too and was also able too connect to using the belkin card in my laptop. As we are going to have some work done on the house I had to move my pcs but the wireless router had to stay where it was.

I purchased 2 Micrdigital wireless PCI adaptor cards F5D7000eaE (which say on the box that they are produced by Belkin). I moved the XP home pc, inserted the pci card fired it up and after some problems sorting out the MAC address for the card and getting it into the MAC table on the router it worked fine. I have the router set up WPA with PSK and AES encryption. The laptop still conencted to the router no problem.

Then came the move of the W98 machine. Inserted the wireless card, switched on, loaded the driver and it saw the network, got the card MAC address put it into the MAC table entered the PSK and it can see the network but it won't connect to the internet or the router setup page.

Whilst I was doing this I put the cd for the PCI cards in my Xp machine to read the manual and the CD autoran and over wrote the driver and in doing so broke the wireless connection with the router. Now it too sits in the same position as the win98 pc in that it can see the network but won't log onto the router control panel.

I've tried the XP machine with both win xp controlling the wireless connection and the pci card control panel but to no avail. I have switched on and off the windows firewall. I have switched off all security features on the belkin router - nothing. The laptop still works fine and I'm connected to the router with a network lead trailed across the living room (which my wife is not too keen on - but never mind).

I have re-entered and double checked the PSK and the MAC addresses but to no avail and as I've said I've switched off all security on it but to no avail.

When I enter ipconfig /all on the XP machine the wireless card doesn't show up.

If I right clcik on the windows wireless icon in the tray and pull up the status panel it says connected with 80-90% signal strength. The pci card control panel has the right network name and security settings, treble checked. It has the right mac address for the router, but no ip address is assigned.

I've tried uninstalling, re-installing the driver, removing the card from the hardware profile and refreshing it, the properties panel says it is working properly - this applies to both w98 and xp machines btw.

Any suggestions?

Thanks
