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.

AR928X Wireless Network Adapter (PCI-Express) (rev 01) that works (tries to) with ath9k module. It connects to my access point and works ok however, It disconnects every 2-3 min saying (in dmesg): [ 311.600306] wlan0: RX AssocResp from 00:1d:68:0c:97:63 (capab=0x411 status=0 aid=2) and then automatically reconnects... I have tried different drivers and other things.... Interestingly when I right-clicked on network manger applet, select ¨disable networking¨ and then set up everything myself on console using iwconfig and dhclient..... IT WORKS!!! no disconnections.... wpa_supplicant is still running in a background but not doing anything (my wifi has WEP encryption). I´ve seen some similar reports in Internet but they seem to think that it is a driver problem when to me it looks like a NetworkManager issue...
