I do not get the error message you get via dmesg on my Sony laptop.
With regard wireless with the latest kernel over and above no signal
level stats due to the bump to WE 18. I have the same connection and
drop out issues. For me the connection is fine for anything web related
that is not passing constant data, but if I vnc to another machine on my
wireless connection, it will die after about 10 mins and require me to
close and restart vnc.
