Westell & Linksys PCI Adapter

I am having trouble getting my Linksys PCI adapter (WMP54G) to work
with my Westel 327W router. I can connect them with the router
unsecured but when I add WEP I can't get them to connect. I'm having
no trouble either way with my laptop.

I'm using 64bit security so my password has 5 characters. I've made
sure I'm typing it in correctly with the right cases.

Any ideas?

Solved my problem.
The instructions Linksys put in the box with the PCI Adapter WMP54G was
for a USB wireless adapter. It had me install the software off the CD
first then install the PCI card. This did not work at all. I then
read the instruction of the CD PDF file. It said to install the card
first and then power up Windows and let it grab the drivers off the CD.
So I removed the card, booted up, removed the Linksys software, then
reinsalledt he PCI card and booted up. Windows grabbed the drives off
the CD and all work perfect from there on.

WOW great documentation
