How to limit network traffic speeds with a network card?

[vpwin7]

I'm not sure if I'm trying to do the impossible but I'll explain the situation.

I have this roommate that is excessively consuming the majority of the networks bandwidth. I've blocked all service ports except for 443, 80, and a few other ones used for every day task. The problem is that he is still consuming a ton of bandwidth, I'm guessing by streaming or downloading through HTTP.

I have *two* WGR614v10 router, and a Realtek PCIe LAN card controller at my disposal. I attempted to set QoS settings on what we will call Base Router. That did not seem to do the trick because router QoS only blocks ports and slows upload speed. Since that did not work I hid the SSID/MAC filtered connections to the Base Router and then connected my computer to the Base Router and rebroadcasted the signal using a Secondary Router using a shared connection, which I gave him access to. The point of this was an attempt to control bandwidth through the Realtek LAN card; I am not having any luck with this though. I've set the adapter to 10Mbps at half duplex already.

Does anyone have any suggestions on what I can look into for limiting bandwidth? I want him to have Internet but not abuse it like he's doing because that is not what we agreed upon.

If you want to solve the issue using your existing equipment, you can try dd-wrt on one WGR614v10. See this thread (DD-WRT Forum :: View topic - WGR614v10 Support - Jump to post 9) which claims that there is a dd-wrt flash for WNR1000v3 which works on WGR614v10. Then look a thread like this (DD-WRT Forum :: View topic - Steps for Permanently limit Bandwidth of a PC using DD-WRT ?) to setup the limits. You can start a new thread in those forums if you want someone to walk you thru the steps.

Or you can just buy a router/access point that has a bandwidth limiting feature for each SSID that it broadcasts.

I appreciate the response but looking into that thread further they merely just flashed another stock firmware from one router to the one I described. This didn't really unlock any special options. I looked into DD-WRT as well but both the devices described in the thread, including my router, are incompatible.

However, after thorough testing I've managed to drop an ~8.5mbps connection down to ~1.5mbps.
Here is what I changed that made the most significant differences:

Within router I changed the MTU to it's lowest setting. (effective)
On my LAN card I changed mode to 10mbps half duplex. (most effective adjustment)
Within router I changed max upload speed to 64kbps using QoS. (effective against streaming and torrents since handshakes require upload speed)
Within router I blocked UDP on the ports I had allowed. (only slightly effective)
On LAN card I adjusted receive and transmit buffers to their lowest setting. (test results weren't persistent enough to determine if this helped)
