As I understand it NetworkManager makes connections according to the following priority order (but correct me if I am wrong!):
Highest priority is given to a functioning wired connection. If (1) is not available, then connection is made to a wireless AP that is defined or that has been connected to before. If (2) is not available, then connection is made to any available wireless AP.
In my home LAN I have two wireless access points and here is where the problem lies. The main servers and primary AP are upstairs. Downstairs is a second wireless AP that I can choose to have the same or different SSID as the priimary, but the channel they operate on is different. I have only run this with wireless G at the present time (before trying later with wireless N)
So when a laptop running F14 is switched on downstairs there is a strong wireless signal from the secondary AP downstairs, and a weaker (but usable) wireless signal from the upstairs AP.
NetworkManager appears not to be able to make a firm decision to connect to the strong downstairs AP and keeps trying to switch back and forth between to the two available APs despite the difference in strength between the signals from the two APs.
This appears to be the same behaviour whether or not the two AP's have the same SSID or different SSIDs. The only way I can keep the connection stable is to make the connection to the upstairs AP not connect automatically.
It would be very nice to be able to tell NM to connect to the stronger of the two AP signals as priority and not keep trying to switch between the two - but I can't find any way to make NM do this? i.e. in my original list of connection priority near the top of this post if there are two available wireless APs with defined or pre-existing connection setups then it appears (unless I am wrong) that NM has no internal rule to prioritise the stronger signal, or to set this as a user config somewhere.
The net result (forgive the pun - it is only just after the New Year!) - is that there are not infrequent brief network pauses as NM retries the other AP.....
Can anyone offer advice on resolving this or should this be a bugzilla report? (upstream?)
Thanks

Is this a problem specific to F15 or Rawhide? If not, general questions about Fedora should go to the Users list.

In principle this is about f14 (and all versions prior!) where I have tested this - but I suspect that these issues are also relevant to f15/rawhide unless changes have been made to the NM and/or wpa+supplicant code between f14 release and now - which I expect has not happened. Hence this is likely to be relevant to f15 and to rawhide I expect?

Maybe, maybe not. If you aren't testing it, how would you know? If you want to bring up a long-standing issue with NM's functionality, which affects users of current versions as well as (possibly) future ones, the appropriate place would seem to be the Users list. Since the Users list is also more populous than this one, you may also get more response.

Or the upstream NetworkManager list:

OK thanks.
