Actually we do have a pretty good wireless G setup, I was thinking about something faster like wireless N. We do have an
Intel 4965agn card that should support N speeds, but I was unable to get it to run any faster than G speeds (steady 60
mbit/s though).

That would be great if you could test wireless N setup if you have one available. We have been using iperf to do
bandwidth tests. It's in Ubuntu repos, just do "sudo apt-get install iperf". Then on one computer run "iperf -s" and on
another run "iperf -c IP_ADDRESS_OF_ANOTHER_COMPUTER".

Thanks!
