Wireless connects, then drops connection

Hello there!

I've installed Driverloader to help me run a DWL520 wireless card on a
pc running Fedora Core 6.

The card works fine - for brief periods. After a seemingly random amount
of time (usually 1 to 5 minutes) the network becomes unreachable.

Other weirdnesses:
Even when working, KWifiManager reports ssid: UNKNOWN

Installed first with driverloader provided drivers. Tried the WinXP
drivers from D-Link install cd-rom; then downloaded the latest WinXP
drivers from the D-Link site. All showed the same issue.

Some other maybe useful points:
The router is running WEP security.
The PC in question connects just fine when running on lan cable
Kernel is the linuxant enlarged stack version.

Driverloader looks extremely useful. We have about 10 pc's I'd love to
get on wireless if I could get it to work reliably.
