For each machine, I had two user accounts as adminstrators.
Had them both logged on using the "fast switching user" screen.
While both were logged on, switch user from one to another caused the wireless connection to reset each time. The consequence of that is that if you were busy with the network : downloading, printing, logged on to web site, etc. you would get kicked out. Also reset takes time getting the IP etc. I have 4 laptops in my household, none of them disconnects while switching. They are not Duo's.
