I had a bit of time getting my Cisco Cards working with NDIS 5.1 since I couldn't find any straight forward instructions to do so.
At one point my PC4800 card worked with Netstumbler but when I had to upgrade the driver on the 340 card to work with Airopeek the PC4800 card stopped working.
Now, with NDIS 5.1, both the PC4800 and 340 card work with Netsumbler. Needless to say, I never had any problems with my Orinoco Gold card.
However, since I switched to the NDIS 5.1 driver, when I start the ACU I get a "you must upgrade your NDIS Driver to use all of the capabilities of this version of ACU!".
I can no longer register to the AP in my office with WEP turned on, using NDIS 5.1. Is this a known issue??? I have not found anything about it in my searches on here or on the Internet.
I'd like to get the Cisco cards to work with WEP but also have them working with Netstumbler.
I will stumble on my way home from work today.
