Description qdii 2012-09-21 17:56:06 UTC
Shortly after a connection is established, NetworkManager disconnects from the AP. Connecting using dhcpcd and wpa_supplicant seems to be working fine, however.

Reproducible: Always

Steps to Reproduce:
1. Start NetworkManager
2. Establish a connection to an AP
Actual Results:  
A disconnection happens.

Expected Results:  
Connection to be established.

Comment 4 Alexandre Rostovtsev (RETIRED) gentoo-dev 2012-09-23 22:24:10 UTC
Please report this problem directly to networkmanager developers:

Attach the logs, your kernel config, and information about the wireless card and driver that you are using. And then please post the bug url here so we can keep track of it.

(I am asking you to write the upstream report because I cannot reproduce the problem, and networkmanager developers will probably need to ask you some questions about your setup so that they can figure out the cause of the bug.)
Comment 5 Alexandre Rostovtsev (RETIRED) gentoo-dev 2012-09-23 22:34:13 UTC
Since the bug appears to be related to ipv6, as a temporary workaround, you may try to disable ipv6 for wlan0 through the gnome-control-center or nm-applet gui (options → ipv6 settings → method=ignore)

The bug was reported on tuxonice 3.4.10 but is still present on tuxonice 3.4.11.

I tried setting ipv6 to ignore, but it did not help.

Is this error still present in networkmanager-
Comment 11 Pavel Šimerda 2013-03-02 14:54:57 UTC
Cannot it be the following bug in dhclient?

There is a lot of dhclient fixes in Fedora that were not accepted upstream.
Comment 12 Hugo Mildenberger 2013-04-10 02:08:46 UTC
This is already a  rather old bug ... but a possible cause is that net.wlan* was started outside of NetworkManager. With OpenRC, the command rc-update show should not list any net.* entries, and and /etc/rc.conf should have rc_hotplug="!net.*"
Comment 13 Pacho Ramos gentoo-dev 2013-06-16 12:03:14 UTC
What is the status of this with Also, it's not clear to me if it's a dhclient problem (can't you test with a dhcpclient alternative) or a kernel driver one :S
Comment 14 Dan Lee 2013-07-18 09:48:32 UTC
Found this , so set ipv6 to "link local only" should work, but you need do it again after next boot.
Comment 15 Pacho Ramos gentoo-dev 2013-07-27 11:13:45 UTC
please retest with
