I was curious, so did a Google search. You don't seem to be alone with this issue.

One forum post suggested that this was related to streaming media, and suggested a fix of changing the MTU value in the DSL modem setup. It had been set to "disabled". The suggested fix was to set it to "enabled" with a value of 1492. (Not sure why a DSL modem would have a "disabled" setting for MTU in the first place, as that doesn't make much sense...)
