Problem with BSSID selection

[Pietro Battiston <me pietrobattiston it>]

I think an extract of my syslog is the best explanation of my problem:

Sep 26 12:50:47 voubian NetworkManager[1417]: <info> Activation (wlan0)
starting connection 'Non-auto Nonna.net'
Sep 26 12:50:47 voubian NetworkManager[1417]: <info> (wlan0): device
state change: 3 -> 4 (reason 0)
[...]
Sep 26 12:50:48 voubian NetworkManager[1417]: <info> Config: added
'bssid' value '00:19:5b:51:a3:e9'
[...]

00:22:6b:a7:54:c1
Sep 26 12:58:15 voubian wpa_supplicant[1436]: CTRL-EVENT-CONNECTED -
Connection to 00:22:6b:a7:54:c1 completed (reauth) [id=0 id_str=]
Sep 26 12:58:15 voubian NetworkManager[1417]: <info> (wlan0): supplicant
connection state:  completed -> associated
Sep 26 12:58:15 voubian NetworkManager[1417]: <info> (wlan0): supplicant
connection state:  associated -> completed
Sep 26 12:58:18 voubian NetworkManager[1417]: <info> (wlan0): roamed
from BSSID 00:19:5B:51:A3:E9 (Nonna.net) to 00:22:6B:A7:54:C1
(Nonna.net)


(notice the 'config' parameter 'bssid'  - set in the connection
properties UI - and the last line).

Is this a bug or am I missing anything?
The situation is problematic because 00:22:6B:A7:54:C1 is a repeater
which is indeed received with a stronger signal, but has a worse
bandwith (since it's further from the AP).

In case it's influent: nm 0.8.1-2+b1 under Debian testing, the network
driver is ndiswrapper, both AP and repeater work on the same channel
with the same password WEP encryption.

thanks a lot for any info
