a bit more info...

on thos slow uploads from the machine I notice the net traffic (as reported by a graphical network monitor) is periodic. For a bit less then a second I get a spurt, and then I get a period of no traffic for a couple secs. This process repeats to give an average tx speed of about 5kB/s. This is vs. my average download speed of 500kB/s.

My dmesg gives this after startup...
