I followed the recommendation from day 1 -- use wicd.  works fine for
me and no dropouts.

> Since about 8.04 or 8.10, perhaps when Ubuntu switched over to NetworkManager, my wireless connection has randomly dropped its association with the access point, about every ten minutes. For a while, the connection will just die, then it will be detected and NetworkManager will re-authenticate and re-associate.

> In Lucid Lynx, this problem is now much more frequent (often exactly every two or four minutes) and now Ubuntu does not report that the connection has dropped. Instead, it re-associates in the background, eventually connecting to the access point again, all behind the scenes. Thus, the only thing that has changed, aside from the greater frequency, is that Ubuntu now doesn't report that it has dropped the connection, which seems deceptive from previous versions.
