   Until recently, we had an 11-year-old modem, on the same "legacy" plan   
   that everyone's talking about. One day about 6 months ago it went   
   flakey, and so the oul' Woman calls Bell (the service is in her name)   
   and gives the details, and (surprisingly) they responded knowledgeably,   
   and the modem came back on and I said "tell them it's slow, too" --   
   because it had been, it was down to like 3 Mb or a bit more -- and the   
   service lady says "oh, hang on" and bumped the speed up right there   
   while we were on the 'phone to 7 Mb. They sent us a new modem, of   
   course, same speed. The service lady had never heard of the old   
   Speedstream that went flakey. The service lady never once went into that   
   "are you using the phone cable that came with the modem?" or any of the   
   other scripted shit. "Reinstall your system software," remember that   
   one? "Oh, you're using a _router_?"   
      
   The moral of all that rambling is that you can call Bell and try to get   
   your speed bumped up. We have a Bell box of some sort on the corner of   
   the street, but we're also only 3 blocks from the CO here in our little   
   corner of Anglophone tranquility. Good luck with that crazy Marois woman.
