Networking/SSH Problems with 9.10

[Tim Henderson]

I am a xubuntu user, however I have found this problem to exist under 
Ubuntu as well.

I realize I was having networking problems during SSH sessions.  While 
ssh'd into my server the network would "drop" for up to 30 seconds at a 
time where any command I typed would not show up in the terminal for up 
to 30 seconds.  Eventually the network comes back and my commands all 
flow through at once.

While I though this was originally an SSH problem, I have realized the 
problem exists while normally using my computer/server.  Firefox 
sessions will just not load for seconds.  During this time I attempt to 
run `host google.com` in my terminal.  A few second pass then finall the 
host cmd loads while the firefox page loads.

I have another computer running 9.10 which is directly plugged in with 
no problems.  And a laptop with 9.10 connecting wireless through a 
realtek NIC, also no problems.......So I assume there is a networking 
issue with either of my Wireless NIC or my router.  I use a Netgear 
Wireless N router and a Gigabyte Wireless G card.

This problem never occurred with any previous versions of Ubuntu or 
Xubuntu dating back to 8.04.

Has anyone had any similar network drop problems on their Ubuntu machine 
running 9.10?

Does anyone know what may have changed between 9.04 to 9.10 regarding 
networking scripts/apps/bins which would effect connectivity?

Thanks,
Tim H.
