Hi I just upgraded from intrepid release to jaunty alpha 6 and now
experience a similar problem. Whenever I start downloading a large file
the wireless connection drops and the network manager eventually
reconnects to the wireless network after some seconds. In the meantime
the connection is (naturally) broken.
Below is a dump of lshw -C network:

Please note that we are using the very same DSL router (Fritzbox 7270) with
different computers (inluding Win XP, Win Vista and, previously on my laptop,
Ubuntu Intrepid and the connection does not break with these systems. Please
also note that this problem does not occur if I use a cable connection instead.
In the router's activity log I can see that my laptop connects and -
after starting a large download at high speed - eventually an
"authentication failure" is logged. Maybe this helps?!
