Things to try.

1.  Try the transfers with the system connected with a network cable. 
This will tell you if it's the wireless driver (possibly, what wireless 
card do you have?) or if it's something with the network settings in Ubuntu.

2.  If the transfer is still flaky with it wired, look at the 
speed/duplex settings.  ethtool is your friend in this case, run it from 
the command line and it will tell you the speed and duplex options for 
the particular interface.  I've seen more than one problem like this 
because of a duplex mismatch or autonegotiate issue.

A lot depends on your wireless card.  A flaky driver will cause those 
problems, but I've not seen a linux driver that is /that/ flaky in a 
while, the new wireless drivers are really very good.
