I'm running into the same thing. Two locations, each with their own WEP keys.
Switching from A to B seems to work ok, but when switching back from B to A, B's WEP key overwrite's A's. It does seem to be a rather scary security issue, having WEP keys sent out unpredictably. -- WEP Key for one SSID carries over to all SSIDs https://launchpad.net/bugs/67788 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
