NetworkManger should work pretty nice and good as required.
Just run the right cronjob every minute to make sure the connection is up or
down and find out if it's possible to reconnect.
NetworkManager is kind of does all you need automatically so you should not
do anything unless there is a technical issue.

The server is in a rack, but the dongle is plugged in the front and is 5m
from the HP Procurv AP that covers the whole of the first floor.

A key point I thought I had included in the OP is that this is mostly a
problem on startup.  It does sometimes drop off during use, but mainly the
problem  is not being able to activate it on startup.

I am a traditionalist and long for the days before NetworkManager when
networks were much simpler to admin, and much more stable.

Is it possible to remove NetworkManager and go back to the good old days,
and still have WIFI work properly?
