I was never able to get a WIC-2T to work in a 3640. Everything I read
seemed to say that it would work, but it wouldn't. The card worked fine
in a 2610.
I posted a message to this list and someone said that the WIC-2T are only
supported if they are in something like a NM-1FE2W.
Attached is a message from July 2000 that clarifies this (although it
doesnt have any links to cisco saying that it won't work)
