Sometimes this happens shortly after beginning and other times when more than midway through.  No
other Internet service is lost.  I have tried various downloads such as linux isos, video downloads,
XPsp2, etc.  I have also switched out the network cards that handle the wlan interface without
resolution.

 It occurs when connecting from the lan and wlan interfaces.  I have only used the default mtu value
of 1500.

Are the downloads from the LAN or WLAN networks ?
Have you looked at the logs to see what may be blocked or dropped ?
What network cards are you using for each interface ?
Have you tried different sources for the downloads ? ie..if you
download a service pack from MS, do you still have a problem vs. some
mirror (and some other file) from say...sharebear ?

It might help if you can post a scrubbed config.xml
I have Comcast here is Richmond, VA, and don't have any problems.
