@Anders: Any improvement in Ubuntu 12.04?
** Description changed:
I have a built-in wifi adapter and a brand new USB wifi adapter plugged
into my netbook. Both are found by network-manager and both can "see" my
home wifi network ("MMM-net"). However, only the built-in adapter is
able to connect. When trying to connect with the USB adapter, I am
prompted for the passphrase, but after a while, I am prompted for the
passphrase a second time. Then again, after a while I am prompted for
the passphrase a third time. Then it fails, saying the network has been
disconnected.
I've tried turning off the built-in adapter (in case this 'confuses' the
USB adapter), but this turns off both adapters (i.e. it turns of WiFi
networking off completely).
