Is there a way to disable access point roaming in F18 NetworkManager?

[William Oliver]

Folk,

Sitting here at work, I notice that my wireless crashes about every two
or three minutes.  When I check my /var/log/messages, I see that I am
roaming between two access points associated with the same ESSID that
serves my whole building.  Both access points are reasonably strong, but
fluctuate a bit in signal strength.

The repeated and constant switching of access points is a big hit on my 
wireless performance.

I vaguely remember an option in NetworkManager to disallow roaming, but
I can't find it.

Does anybody know how to stop this?  I looked at the man page for nmcli,
but didn't see anything about roaming...

I seem to have found an answer.  I can indicate the BSSID.  So, my
steps are:

1) Connect to the wireless access point
2) Watch /var/log/messages to see the BSSID
3) Open up NetworkManager
4) Put in that BSSID (or simply choose it -- in one case, it populated
automatically when I pushed the "select" button beside BSSID).

Since it populated automatically once I was connected and hit "select"
it may be that I don't even have to look at /var/log/messages.

In any case, that seems to stop it from jumping around.
