DLink DWL-520, firmware 1.4.9, used in STA mode.
kernel 2.4.20-pre11, wireless extensions 14.
hostap-2002-10-12 is installed, but I use mainline kernel's orinoco_pci.

Will try with hostap (and kernel 2.4.20) instead.

Just curious: what "kernel: eth0: Station identity 001f:0006:0001:0003"
means? It prints this at modprobe time.

Gory details just in case you are interested:
