Hi,
having similar problem here, i am using lucid on a T61 lenovo.
and i get random problem when connecting to my servers using SSH.
after reading this discussion:
https://lists.ubuntu.com/archives/ubuntu-server-bugs/2008-June/003360.html
i tested when having errors on ssh to restart the wireless (turn off and
back on)
and ssh connection just worked
