Just posting this due to a problem I encountered, and found the fix for it here, for a similar context.
I was working on setting up a bunch of new wifi sets for cabins, so I have a number of stations that have overlapping coverage. I was annoyed by the constant pop-ups I was getting from my wireless trying to connect as I was knocking stations down & back up, so I went to Network Managed and unchecked "Enable Wireless"
The GOTCHA is that I could not re-enable my wireless adapter!! It had disappeared entirely.
I found the rfkill suggestion from Biff in another thread here

and I had a soft block on my wireless. I ran the unblock, but still had no option to restore my wifi, Argh!
I immediately rebooted, and tried NM again; voila! I had the checkbox back to enable wireless networking.
HTH someone
