Is there a way to specifically control which networking interfaces are brought online automatically by NetworkManager when I login? I have two wifi cards, one of which doesn't work, and I need to be able to specify "Don't automatically bring up wlan0" so that my wifi works and is stable.
Right now, I disable the interface by doing
sudo ifconfig wlan0 down to manually bring down the interface after login, but I'd like to not have to do that step.
The system this is primarily going to be used on is a Precise (12.04) system, but I would also like this to work with later versions as well.
