Public bug reported: Binary package hint: network-manager
I have had the following bug since Ubuntu 6.10: - I connect to a wireless network with Network Manager (doesn't matter whether it's hidden or has any type of encryption) - After a few minutes my connection goes down (usually around 10-30 minutes) - I can immediately see nm-applet trying to reconnect or connect to another network My computer is a Thinkpad T60 with an Atheros-based internal wireless interface (more specifically, AR5212 802.11abg NIC) using the default MadWifi drivers that are shipped with Ubuntu. This is a big problem when doing long downloads, or using SSH or VNC. At times, nm-applet would even fail to reconnect to any of the available networks, requiring me to restart the NetworkManager process by hand. This does not happen on the same machine when running Windows, so malfunctioning hardware and anything external to the computer are obviously not the underlying cause. Other (Windows) computers on the same wireless networks operate without any problems. Also, the problem survived through clean installs of Ubuntu 7.04 and, later, 7.10. So this is not an issue related to my specific settings. After a while looking for a solution for almost 1 year, I finally found a temporary fix: to disable IPv6. I'm not sure *why* this works, but the fact is that it *does*. I've been happily using my WiFi now for 20 days without a single reconnect. This is how I disabled it: - edit /etc/modprobe.d/aliases - change line "alias net-pf-10 ipv6" to "alias net-pf-10 off ipv6" - reboot I explained these steps on another bug report (https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/64173), but since I'm not sure whether the original poster's bug was related to mine, I figured it would be better to open a brand new one. ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- IPv6 causes wireless to disconnect/reconnect often https://bugs.launchpad.net/bugs/158481 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
