Title:
Wi-Fi connection lost every minute -- iwlagn
Status in “network-manager” package in Ubuntu:
Expired
Bug description:
Binary package hint: network-manager
Hello there
I am quite undecided where to file this bug, but as far as I can see
it could be something between Network Manager and something in the
kernel (drivers)?
The NM version I was using was the following (I had to switch to
wicd):
bronto@lotus:~$ sudo apt-cache policy network-manager
network-manager:
Installed: (none)
Candidate: 0.8~a~git.20091013t193206.679d548-0ubuntu1
Version table:
0.8~a~git.20091013t193206.679d548-0ubuntu1 0

0.7.1~rc4.1.cf199a964-0ubuntu2 0

As Google reveals, I am one of those users that experimented problems with
wireless connections after the upgrade from 9.04 to 9.10.
After the upgrade, NM successfully connects to the wireless network,
but it loses it after less than a minute. It retries to connect short
after, and may succeed again, to lose it once again less than a minute
later.
To understand if this was a NM problem I did the following:
1) disabled wireless from NM, added this entry to
/etc/network/interfaces:
iface wlan0 inet dhcp
wpa-ssid WiFiBronto
wpa-psk PutYourKeyOnLaunchpad!
ifup wlan0 successfully configures the interface, and the connection is
stable.
2) used wicd instead of NM: the connection is stable
3) removed the connection from NM and re-created it from scratch: the
connection is UNSTABLE
4) reset the AP to factory settings and reconfigured: the connection
is UNSTABLE
5) installed the latest kernel from jaunty, booted it: the connection
is stable (but, unfortunately, I have no audio...)
Messages in the logs in case of unstable connection are similar to the
ones I am attaching from /var/log/syslog
My Ubuntu installation is a pretty standard one, that started as a
8.04 and was upgraded up to 9.10. The only non-standard configuration
is that I eventually had to disable pulseaudio due to crappy audio and
high CPU consumption (I think it was at 8.10).
bronto@lotus:~$ lsb_release -rd
Description: Ubuntu 9.10
Release: 9.10
My PC is an HP Compaq 8710w laptop. The wireless card, as reported by lspci,
is:
bronto@lotus:~$ lspci | grep -i wireless
10:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN
[Kedron] Network Connection (rev 61)
The driver is a iwlagn:
bronto@lotus:~$ lsmod | grep iwl
iwlagn 109052 0
iwlcore 112540 1 iwlagn
mac80211 181076 2 iwlagn,iwlcore
cfg80211 93052 3 iwlagn,iwlcore,mac80211
led_class 4096 3 iwlcore,sdhci,hp_accel
Is this a real bug or I did something wrong?
Thanks in advance for any solution you could provide.
Ciao
