Did you try this? So I'm confused. That's a fix in Network Manager source, but I thought the problem was suppose to be in the Atheros driver not in Network Manager. Or does that longer timeout just suppress the detection of the Atheros driver disconnecting so that Network Manager doesn't show the disconnect? What's the status of .7? If that is indeed a fix then will that make it in .7? I'm also waiting for .7 to have a system wide store for my WPA keys. -- Bill Moseley [EMAIL PROTECTED] ___ NetworkManager-list mailing list NetworkManager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

Re: Frequent Disconnects
So one working method to decrease disconnects seemed to be to increase the timeout for link losses. Taken from the bug report, changed src/nm-device-802-11-wireless.c, line 2318 from self->priv->link_timeout = g_timeout_source_new (8000); to self->priv->link_timeout = g_timeout_source_new (2 I am willing to try this, although I think the first step would be to eliminate the possibility of a driver problem.

Re: Frequent Disconnects
Seems this is quite a common problem. I don't know if it helps at all, but there are a couple of user submitted patches in the Ubuntu bug system aimed at sorting it out. The one at the bottom of this thread allows a user configure the reconnection timeout: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/64173 Here's another related bug: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/37821 Also, after using network manager to get your connection up, issuing a kill -STOP to the NetworkManager process seems to stop the reconnections.

Mine is not weak signal. I'm just a few feet from a Netgear WG302 and nm-applet shows all bars solid and something like 80%. My other linux laptop running Sarge and an Apple iBook don't have this problem. The linux laptop is not using wpa_supplicant, either. Can you explain how to generate useful debug logs?

Weak signal strength could cause them if you're at the margins of the network, and the driver looses sync with the AP. But if you still get disconnections (ie, iwevent shows SIOCSIWAP events of 00:00:00:00:00:00) when you're right next to the AP then we really need debug logs from the driver to figure out why it thinks it's being kicked.

AFAIK, it always gets turned into a hex key of length 64. Check the encryption key listed in iwconfig. Wit a signal strength of 44, it wouldn't take much interference to knock you off-line. It could come from a portable phone (not cell), a baby monitor, a microwave, or any number of sources. Google "wifi 2.4 interference" to see some ideas on what can interfere and how to avoid it.

Now it's back and at 44%. OK. Start with what kind of Linux computer it is. You seem to think it is NM that is causing the problem. Provide all the things that make you think so.

I too have been experiencing this a lot and when my laptop is just a few feet from the AP, a Netgear WG302. My laptop (Thinkpad T60p) is just a few days old so have not had time to look at the problem -- I was wondering if it was due to dhcp leases renewing, although that sounds very unlikely. I'll try and watch the logs more carefully next time I'm on the wireless and see if I can capture anything interesting in the logs. The little single strength meter in the nm-applet still shows strong signal, although I also noted that it continued to show strong strength after unplugging my AP. It may not be quite real-time, I guess. Another difficulty I had initially was that my AP had no security enabled -- but I had my ssid set to not broadcast. My other two laptops (iBook and Debian Woody) associated fine as long as I typed in the essid. The T60p would sometimes manage to connect but it was rare. I enabled broadcast and WPA-PSK and not it connects without problem. I then disabled WPA-PSK and it still associated so my guess is the non-broadcast ssid was the problem. I tried to test that theory a bit by changing the ssid of the AP and toggling ssid broadcast, but it seemed like the laptop was remembering the AP by MAC address so it wasn't easy to test. Sorry, this posting is a bit premature since I wasn't able to test much.

I too have been experiencing this a lot and when my laptop is just a few feet from the AP, a Netgear WG302. My laptop (Thinkpad T60p) is just a few days old so have not had time to look at the problem -- I was wondering if it was due to dhcp leases renewing, although that sounds very unlikely. I'll try and watch the logs more carefully next time I'm on the wireless and see if I can capture anything interesting in the logs. The little single strength meter in the nm-applet still shows strong signal, although I also noted that it continued to show strong strength after unplugging my AP. It may not be quite real-time, I guess. Another difficulty I had initially was that my AP had no security enabled -- but I had my ssid set to not broadcast. My other two laptops (iBook and Debian Woody) associated fine as long as I typed in the essid. The T60p would sometimes manage to connect but it was rare. I enabled broadcast and WPA-PSK and not it connects without problem. I then disabled WPA-PSK and it still associated so my guess is the non-broadcast ssid was the problem. I tried to test that theory a bit by changing the ssid of the AP and toggling ssid broadcast, but it seemed like the laptop was remembering the AP by MAC address so it wasn't easy to test. Sorry, this posting is a bit premature since I wasn't able to test much.

In any case, are you moving around at all? In your first log file, you connect at 8:17, then: Jul 15 08:19:15 localhost NetworkManager: ^Iwpa_supplicant(6734): Wireless event: new AP: 00:00:00:00:00:00 and the driver appears to get angry with you, since it disconnects you again during the association a couple of times. About all we can do right now is try to get debug output from the driver itself to find out why it's sending disconnection events to userspace.

Frequent Disconnects
Hi all, I'm not sure if this question is exactly appropriate for this mailinglist, but my computers experience frequent disconnects (and sometimes reconnects) from my WPA network while they are booted into linux and using nm. In windows they do not disconnect, leading me to believe it's related to linux in some way. I've been looking at /var/log/syslog, and it contains lots of information about the disconnects, but I can't tell what it means or what to do about it.
