Network problems, out of ideas, wtf is going wrong *SOLVED*

hello H&A! I am coming to you because something has gone wrong with my home network and no one can seem to figure out what.

SUMMARY: Upstream connection speed intermittently drops to <60 Kb/s, resulting in everything internet related working horribly slowly.

MY SETUP: Internet connection comes from Comcast via cable modem, which connects to my Linksys WRT54GL router, which operates 1-3 wireless connections to whoever is using a computer in the apartment.

BACKSTORY: The problems began when my roommate replaced our old Belkin router with an Airport Extreme. This was about three weeks ago; I never noticed the problem with the Belkin. Since then I picked up the Linksys and swapped it in, which worked fine for a couple of days. But then this morning the same shit started up again.

WHAT THE PROBLEM IS NOT/WHAT I HAVE TRIED: It's not wireless interference, since the problem presents on a wired connection to the router as well. It's not my computer, since everyone on the network has the same problem. It's also not a problem with my Internet connection itself, since plugging a test PC directly into the cable modem via Ethernet cable works perfectly. I also have to assume that it's not directly a router problem, since the same problem has now happened with three different routers (although it seemingly started when we brought the AirPort online, could that have caused it? Could my network have caught some insane Apple virus?? that doesnt even make sense)

HELPFUL (?) INFORMATION: Here's a tracert showing that there's no problems between my PC and the router; it's only when data tries to get upstream from my house that things start going awry:

And here is a speed test, showing that downstream works OK:

If any technical wizards out there need more information I will do my best to supply it, but this is all I can think of for now. Thanks a lot if anyone has any thoughts on this; I am seriously about to strangle a hobo unless I can figure this shit out. Fix my network and save a life! (A hobo life)

    Holy shit that is some fucking LATENCY.

    Edit: so have you swapped the Belkin back in?

    Do you use any bittorrents? Sometimes Comcast will throttle you if you are using too much bandwidth with them. WoW patches are distributed by bittorrents don't forget, so this might also be a hidden cause.

    You can also try this to help confirm/deny said throttling.

    FYI here's some more info on what I'm talking about.

    Hope this helps.

    e: fixed links.

    What happens when you connect a single PC directly to your router with no other machines connected? (may want to disable the wireless on your router to be sure). Check with a different PC if the problem shows up on the first one.

    Throttling is the first idea that comes to mind, though.

    pretend that I am a dumb idiot for a second and explain what that number means--I know that high is bad but that's about it!

    also, it went like this: Belkin (no problems) -> AirPort (problems) -> Belkin again (problems) -> Linksys (problems)

    I don't use bittorents hardly ever, my roommate might have some open though. I will ask him. Here is what that tool said (assuming I clicked the right one):
    TCP/Web100 Network Diagnostic Tool v5.5.4b
    click START to begin

    ** Starting test 1 of 1 **
    Connected to: ndt.iupui.nuq01.measurement-lab.org -- Using IPv4 address

    ACTION NEWS UPDATE!

    Asked my roommate to hold off on Midget_Grandmas_Fucking_for_CASH[xVid-LOL].torrent for a few minutes, and the latency problems vanished instantly. Now as part of the scientific method, I have a couple of torrents open and everything seems fine (so far). I don't know what client he uses; could it be possible that he just needs to enable some encryption setting to keep the Comcast goons from noticing the traffic and making our lives difficult?

    Torrenting is the slayer of connections.
    Fought with roomates doing this all of the time in college. Standard torrenting will hog all bandwidth no matter what, but the faster he's downloading/uploading, the slower you're gonna get.

    Tell him to knock it off or he gets a cockpunch, or do it at sensible hours (Ex. Both gone, late late night, etc...) or you reserve the right to terminate his connection at router level in the middle of his fap sessions

    I would have no qualms whatever with doing this, but it seems weird that I can torrent without difficulty but he can't, no? Which suggests that his using a different setting/client might be a solution as well.

    I use uTorrent btw, no idea what encryption settings since I usually just click buttons at random

    He could just be downloading/uploading more than you, or be connected/seeding to more peers.

    Have him set his upload limit to like 15 kb/s that way it won't hog too much of your bandwidth. I used to have this exact problem when I lived with a guy who was afraid the Internet was dead.

    Also make sure he isn't connecting to a ridiculous number of peers at once.
