does this mean anything?

[Derek Trotter]

You might be aware of my problem with my dsl service.  Earthlink appears 
to be unable to figure out what's going on.  Some networks I have 
trouble with.  When a problem shows itself, the entire connection 
stalls.  This affects anything coming in, even if it's from a site I 
normally don't have trouble with.

Tonight I went to speakeasy.net/speedtest and started tcpdump, saving 
it's output to a text file.  Then I clicked on Seattle which is certain 
to make the problem show itself.  Here 
http://home.earthlink.net/~azspamhater/tcpdump.zip is the output of 
tcpdump from when I started it to when I stopped it right after the 
speed test told me the download test was complete.

Here's the bit from tcpdump's output when the connection stalled.  Can 
someone who understands this stuff please tell me what it means?  Thanks.
