Have you find a solution ?

I've the same problem with a Linux machine.
I've a redhat 7.3 (Kernel 2.4.22) on Satellite Pro 4600 Toshiba.

The wireless card is like PrismeII and i use orinoco_cs module.

[root@blabla root]# cardctl ident
Socket 0:
   product info: "TOSHIBA", "Wireless LAN Card", "Version 01.01", ""
   manfid: 0x0156, 0x0002
   function: 6 (network)

Whem we use 40 bits keys for WEP it-s fine but with 128 bits keys there 
is problems.

Some others informations :
