I have exactly the same problem on ubuntu 12.04, AMD 64 with the following setting of wireless:

I upgraded my laptop from Dapper to Edgy a few days ago, and have since then had a problem with the wireless network. The problem is that the wireless network will reconnect periodically with intervals from a few seconds and upward (a connection usually lasts between 5 and 15-20 minutes before it happens again). Usually the reconnection is quick enough that existing network connections are not interrupted, but sometimes that happens too. Some Googling on similar issues seems to indicate that the reconnection can be triggered by Networkmanager trying to scan for APs, but I certainly cannot prove anything. I don't know enough about wireless networking to be able to completely understand what gets written to the system logs either, unfortunately (see link below). The laptop in question is an LG LW20, an Intel Centrino-based thing with Intel2200 wireless card (uses ipw2200 driver). The wireless network was rock solid using Dapper, same configuration as now with Edgy. I use knetworkmanager to configure the network, which uses WPA/AES (the same problem exists using WPA/TKIP and WPA2/AES, btw). My wireless router is a Linksys WRT54G with DD-WRT firmware, but I doubt that the router is the guilty one, since the same setup worked perfectly when Dapper was installed on the laptop. Here is what gets written in the daemon log when the reconnection happens: http://hem.passagen.se/l71/daemonlog-excerpt.txt OS & software versions involved: Edgy Eft, current updates as of 5th october, network-manager 0.6.3-2ubuntu5 knetworkmanager 0.1-0ubuntu1 wpa-supplicant 0.5.4-5 ipw2200 version 1.1.2 ieee80211 stack version git-1.1.13 Please let me know if there is anything more I can do to help, increase debug info levels, etc. Thanks in advance and best regards, Lars To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/64173/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
