Windows 98 and Wi-Fi / WPA encryption

So, it turns out that my Linksys Instant Wireless Network Card (WPC11 ver.3) does not support 802.11b WPA encryption under Win98; only 2000 and XP. There is a free WPA add-in program for 98 available from Wireless Security Corporation, but so far I haven't been able to even get my wireless adapter to see the access point with or without it (unless I set it to flawed WEP encryption).

I'm thinking I might just upgrade to Windows 2000 to get better support and avoid this junk of not being able to get WPA to work. Further updates as discoveries/conditions warrant.

Update 11:00PM: I did get my laptop to connect at last using WEP (but not WPA). I had to uninstall the Wireless network card (I also uninstalled the wired network card, but that's probably irrelevant), reboot, install the drivers with the card out of the machine, then insert the card after the drivers were installed. I also installed a 98 networking hotfix, but I don't have the number handy right now - will post it later.

I noticed I had to set the access point to broadcast the SSID; otherwise the Linksys Wireless Configuration Utility couldn't connect to the AP, even if it had been connected a moment ago. For the time being, I've restricted wireless access to the MAC address of my wireless card, but that just means that the wireless AP will reject any communications from other cards; my communications are still out there, protected by inherently insecure WEP encryption, and readable by anybody willing to do some wireless packet sniffing. Maybe I'll just run an encrypted VPN session through the WAP to one of my wired desktop computers.
