Hi again Jes, good news, I do not know what I did wrong before, but I am retesting above kernel and dongle and things seem to be working from the very beginning, no problems found after plain boot (just need to enable the network twice, but that also happemed with the old b/g dongle, may be something with network manager). This is not my usual box, it is slow and I do not have it accesible in a daily basis, but feel free to ask for further testing. Will try to make my best. Best regards, -- Agustin
