A few months ago I encountered throttling on my Teksavvy account in the Queen St. East area of Toronto. It was being done by Bell as that is who supplies Teksavvy its lines.
The following was posted to the DSLReports.com back in May of 2008 and is a simple work around for people who don’t want to invest time into learning about MLPP. For the original post click here…kudos to HiVolt for the post…

“Here is an idea for the people who have non-WRT54G linux capable routers, to temporarily use the MLPPP trick in Windows, in order to bypass the traffic shaping.
Set your modem in bridge mode & disable its DHCP server, and your router should be configured to use your TekSavvy PPPoE login, as usual.
What the loopback wiring allows you to do, is to establish a PPPoE connection using Windows XP, with the multilink checkbox, while your router is still connected in the mix and can still supply your other PCs or devices with internet. When you connect in Windows using it’s built in PPPoE, it overrides whatever is supplied by your router, so you can download a torrent or use whatever application is affected by the DPI.
However, as you can see, it eats up two ports on a typical 4 port router. If you have another switch with more ethernet ports, you can easily uplink to your router and your problem is solved. Also, as this creates a direct IP connection to your machine, it bypasses the firewall of your router. So make sure to at least enable the Windows firewall, or use some other firewall software of your choice. Otherwise, you’re left exposed to the net with a direct IP. One last thing. If you have a singlestatic IP, you will have to manually force a disconnect in your router’s web interface, as an account with a single static IP will not be able to connect again unless its disconnected. You can then establish the PPPoE in Windows.
As an added bonus, you can now access your modem’s line stats without unhooking your router. Just make sure the modem’s IP address is different than the router’s. If not, change one, for example the modem 192.168.1.254 (ST516), router 192.168.1.1″
