I've got a built in ambit wireless adapter on my laptop which I cannot
get to connect to my wireless lan.

KNetworkManager shows the device as
Intersil Corporation Prism 2.5 wavelan chipset (wlan0_rename)

My router is set up with a hex wep key and I have 5 other devices
connecting to the wlan just fine.

openSUSE just won't connect to it though. If I run iwconfig I can see
eth1 and wlan0_rename.

wlan0_rename shows an increasing number against Rx invalid crypt.

Any suggestions how I might get this connected?
