My WAP11 died last weekend - wrong voltage, erm - so I can't try it now,
but:

When I first got my WAP11 it was delivered to my office and I wanted to try it,
so I hooked it up to my notebook and connected to the wavelan at the lab.
I just talked to the net-admins and they told me we only use Cisco equipment and they think the lab access point is a Cisco Aironet 1200.

So I'm pretty sure the WAP11 works as a client for the Cisco AP.
My replacement just got delivered to Bergen County, NJ and should
be here (Germany) in 2-3 weeks....

I'll try again as soon as I get it.
