Win2k and WEP encryption

[WildBill]

I have an HP laptop with a built-in Mini-PCI LAN-Express wireless modem (combination 56k modem and 802.11b wireless LAN card). I've had a heck of a hard time getting WEP encryption to work on it, and for now at least I've settled on the free version of WPA Assistant. It seems to work for the most part, but every once in a while the PC freezes for an instant when I'm doing certain things (e.g. run 16-bit apps). For those of you who use wireless and Win2k, what do you use? Is there something better?
