I have two 340 Series Cisco/Aironet PC cards. When I run the Client Encryption Module on one of the cards it states that "WEP support has not been purchased". I didn't know you could get it without that option. I have upgraded both cards to Firmware Version 4.25.10 and that doesn't have any impact. Since it is on the same PC I don't think the driver is a problem.
So the question is how do I upgrade the card to include WEP.
