This worked - update installed… however!..
My wireless radios seem to have swapped over, what was Radio0 is now showing as Radio1
so 0 = bg and 1 = bgn.
Problem is, my Radio0 was my N access point!
I seem to recall this happened a long time ago and I needed to swap the references to what was Radio0 and Radio1 but I can’t quite remember which config file that was in?
EDIT: I suspect it has something to do with being on a mSATA drive and I think I had to do this originally… Info: Small thing to do after adding mSata SSD
