However the same hardware with Win2K fails. The weird part is it will work fine until I install the Novell Client, so, this may be the wrong forum, but I will try anyway. I experience this problem with Linksys, 3com and Ralink adapters. They authenticate fine until I install the Novell client (4.9 - 4.9.2). Once I install the NW client the machine wants a client certificate and then will authenticate intermittently and always fail re-authentication. The only adapter that functions in this setup is Gigabyte GN-WPEAG. I have ordered a more recent version of Gigabyte adapter which also uses an Atheros chipset.
