This bug has been driving me round the bend now for three releases of Ubuntu. Edgy, Feisty and Gutsy. I really don't know why it isn't getting fixed, any ideas? Using network manager and the madwifi drivers (atheros chipset) cause the user to be disconnected from the access point at regular intervals. This bug seems to be knocking around in lots of incarnations and the problem seems to be this: 1) The madwifi drivers don't support 'background scanning' 2) Network manager instructs the atheros based card to scan for access points in the background whilst it is already associated with an access point. Because the madwifi drivers don't support background scanning, when the instruction to begin background scanning is given then the network card disassociates with the access point, disconnecting the user. This bug is a show stopper for any new user, as they are unlikely to dig into the problem to find out what's causing it.

This bug has seriously turned some people off Ubuntu but no-one seems to want to take responsibility for it... -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
