I had to do some weird stuff to get my WG311v3 wireless card to work on a Compac Presario 6000 running VL 6.0.
modprobe ndiswrapper would not work. So, I added a new folder (126.96.36.199) in /lib/modules and copied over all the stuff form 188.8.131.52. Then ran modprobe -f ndiswrapper and that worked. Changed the /etc/rc.d/rc.local to force load of ndiswrapper on reboot by adding modprobe -f ndiswrapper. Took a while and some help from my son to do this.
Then VLwifi worked fine.
However, WICD does not work. I use wep. I can see my wireless router (WICD calls it a network) as well as some others. I can get online with WICD to one of the "others" that is unencrypted. But I can't get onto my wep network. WICD says it is seeking authorization or some such and never goes past that point.. The little bar keeps moving back and forth but nothing connects. I think the problem might be in the way I put in the password. It insists on a password in wep(hex), passphrase and wep restricted. Won't let me erase all the info in those spaces and start from scratch.
