Bug Description
Binary package hint: network-manager
When connecting to wireless networks with multiple access points with the same SSID, the nm daemon repeatedly tries to associate. Generally the connection will only last a minute or two. Both the nm-applet and knetworkmanager (the new kde4 version) front ends have the same issue.
The syslog reads as follows:

But subsequent DNS lookups fail. Tried removing and re-inserting the ath5k module, restarting the NetworkManager daemon, etc... Clicking connect on the network will reconnect, only to roam to (none) (none) later.
Running the latest karmic packages.
summary: |
- networks with multiple access points roam too frequently + networks with multiple access points roaming fails |
dupe of bug 291760 ... due to background scanning. since the fix on driver side appears at least in reach, i am not sure if we should still invest what it takes to make user experience good without background scanning.
