I switched to channel 13. Less problems but if the Internet connection
is (shorter) blocked I get:
Or:
sudo iwlist wlan0 scan
wlan0 Interface doesn't support scanning : Device or resource busy
Or:
wlan0 Scan completed :
Cell 01 - Address: B0:B2:DC:10:33:6C
Channel:13
Frequency:2.472 GHz (Channel 13)
Quality=70/70 Signal level=10 dBm
Encryption key:on
ESSID:"Zadel"
Cell 06 - Address: 00:0C:F6:42:DD:9A
Channel:11
Frequency:2.462 GHz (Channel 11)
Quality=70/70 Signal level=10 dBm
Encryption key:off
ESSID:"Sitecom"
The Quality is the same and that should not be possible. So, something
very low level is going on. It is beyond my capabilities to debug this.
The problem is driver bound. That is, some drivers never have this
problem. At my place an Intel N2230 driver. Other drivers have a lot of
problems. That my home Rtl8192se drivers.
So, it is still not clear what causes this bug.

Title:
NM disconnects Wi-Fi every 2 minutes but iwconfig+dhclient and wicd
don't -- ath9k
Status in “network-manager” package in Ubuntu:
Confirmed
Bug description:
Binary package hint: network-manager
I have Dell studio XPS 13 running:
Description: Ubuntu 9.10
Release: 9.10
with wifi card (lspci):
06:00.0 Network controller: Atheros Communications Inc. 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...
Hope it helps....
