But if I log in as a different user on the laptop and set that user up to access the wireless with exactly the same configuration, it connects perfectly but then dies and reconnects every 15 seconds or so. This happens for any other user both with and without admin rights. I assume the 15 second cycle is related to the rekey interval for WPA. It also happens if I set up another computer using the Belkin card I bought with the router, although the same computer will work perfectly using its own internal wireless card.
It tells me it's lost the network connection (repeatedly, every 15 seconds!), but I'm right next to the router, and of course, it works perfectly if I'm logged in as the particular user.
In the Wireless Event viewer log it's giving the message "EOUCONFIG: GetOid for scanlist failed" about which I can find nothing.
Any help would be appreciated.
