When I had the same problem, it turned out to be the cable broadband 
that caused it.   I had purchased a Cable modem from the cable 
company when I had broadband installed several years ago.   When I 
filed a complaint about the speed, they said the modem I was using 
was no longer supported by the cable company when they "increased" 
the speed for no increase in price.  The older modem did not support 
the new protocol that they had introduced (without making this 
incompatibility known to customers).   My speeds would vary all over the map.
