Couple of ideas.

  - run tcpdump -s0 -X >dump.txt during a bad download and see if the 
content of the packet is bad.  TCP checksums should find bad stuff in 
transit

  - there can be memory or disk problems *on the server* not on your 
client.  If you control the server test this also.  This would explain 
why the TCP packets are not seen as corrupted, the data was corrupted 
before it was sent over the network

  - If you control the server, try downloading synthetic files, eg dd 
if=/dev/urandom of=testfile bs=1024 count=1024 will generate 1M of 
randomish junk.  Look for commonality if there are errors in that too.

  - Network driver could be crapping on its buffers I guess.
