I have a desktop with a Fritz USB WLAN N stick and tried Ubuntu 12.04. Installation went fine and WLAN is working. However, connection drops permanent. Reconnecting manually fixes it but after a few minutes it drops again. It's connected to a Vodafone 802 box with WLAN N fix set. It seems that it works when I switch off N mode. But I need to test. Can someone confirm this issue or is there another solution?
I have another machine with 12.04 (HP 625 laptop) running where connection is stable.

Perhaps a dupe here. The tricks below worked for me a day but now they are again not working, irritating! So this case is not resolved at least with Thinkpad X220.
I. Generic partial solution
II. Some Intel models
