I apologize if this is the wrong bug.

I do have the same problem. On my machine the Networkmanager links up with a SSID that is the strongest access point (of my neighbors) , but that access point is not configured. Hence, the link dies, takes some time to recover and then the sequence starts again after two minutes. The bug is that Networkmanager should not make a connection to a not configured access point even if that has a better signal.

In debug mode.

The wrong SSID:
 wpa_supplicant[1259]: wlan0: BSS: Expire BSS 13 due to age
 wpa_supplicant[1259]: wlan0: BSS: Remove id 13 BSSID 00:1a:70:47:b0:de SSID 'linksys'

The right SSID:
wpa_supplicant[1259]: wlan0: 0: b0: : : : ssid='Zadel' wpa_ie_len=0 rsn_ie_len=20 caps=0xc11 level=10

With the command iwevent the two minute scan reveals itself.

So, if there is no stronger access point than the configured one, the problem does not surface.
