Description of problem: network manager applet has no option to disable a specific interface while leaving another functional (at least for wireless) Version-Release number of selected component (if applicable): How reproducible: very Steps to Reproduce: 1. install 2 wireless cards that are supported 2. try to disable one using the network manager applet 3. reach same conclusion that I did. there is no way to do it currently. Actual results: impossible to do Expected results: select "disable" option next to specific card and have it disconnect and take down the interface and not try to reconnect Additional info: I know two wireless cards in one system is rare, but that's what I have.
In Fedora 12, you can disconnect either or both of the wifi cards and it won't auto-activate. Unfortunately until the 2.6.32 kernel it's not possible to rfkill just one of the cards, because it's not possible to conclusively match up each card to its rfkill switch if there is one. We also can't tell which card is internal and which is external, or whatever. So I'd give Fedora 12 a try and use the "disconnect" option which should pretty much be what you're looking for here.
