Bug Description

Binary package hint: linux-restricted-modules

  Installed: 2.6.24.16.18

I'm using the Madwifi driver with a Netgear WG511T wireless card on Hardy. Quite frequently it will disconnect for a few seconds and then jump right back on the network. Sometimes it's so quick it's not even noticeable. Whenever this happens Networkmanager will dump a couple of these in the logs

Apr 20 23:31:53 P3nguins NetworkManager: <info> Supplicant state changed: 0
Apr 20 23:31:55 P3nguins NetworkManager: <info> Supplicant state changed: 1

As I mentioned before this happens quite often, so Networkmanager is completely flooding my logs with these messages.

This is a WEP encrypted connection if it matters.

Hi futurepilot07,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISOs are available from cdimage.ubuntu.com)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

The output of lspci -vvnn would also be worth having.

Hi

I was using the ath5k driver on Intrepid until they switched it back to the madwifi driver. I didn't appear to have this problem with ath5k. Now with madwifi I'm still seeing disconnect and reconnect behavior and flooding of the logs. I'm using WPA2 now and in the logs NM keeps spitting this out every few seconds:

NetworkManager: <info> (ath0): supplicant connection state change: 7 -> 0
NetworkManager: <info> (ath0): supplicant connection state change: 0 -> 4
NetworkManager: <info> (ath0): supplicant connection state change: 4 -> 5
NetworkManager: <info> (ath0): supplicant connection state change: 5 -> 6
NetworkManager: <info> (ath0): supplicant connection state change: 6 -> 7

which I think is a disconnect. This didn't happen with ath5k

This also happens in my laptop. Sometimes I loose the wifi connection encrypted with WPA2 and with an Atheros AR242x card. In /var/log/syslog appears these messages:

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.

The ath5k driver does not have this problem. I haven't had this problem since Ubuntu switched to the ath5k driver.
