LAN help, bandwidth hog.

Skorpion9x · 03-31-2007, 05:36 PM

So here's my situation. I live with my two brothers, and we share the same cable internet connection, with a Linksys BEFSR41 V3 wired router with 1.05.03 firmware (I checked the Linksys site for a newer firmware, but the latest on there is 1.05.00).

We used to all play WOW a lot, but recently one brother quit the game, and now he downloads a fuck ton of shit, and causes our connection to lag like a motherfucker. I'm talking 1-2 seconds of lag in the game. It's ridiculous and I'm sick of it.

What I want to know is if there is any kind of software that I can get - to download or buy (nothing too expensive) - to limit his bandwidth or lower his priority so we can enjoy a relatively lag free gaming experience? Any help would be greatly appreciated.

See if your router supports Quality of Service (QoS). You can use it to limit bandwidth per ethernet port.

[Edit]It should appear as a tab under Applications & Gaming.

If he's downloading shit via torrent, cap his upload speeds to 10kb/sec or less. When I was living with roomates, it wasn't our download bandwidth that caused the problem but the fact that he was choking our connection by overloading the upload bandwidth (which is usually a major chunk smaller than download bandwidth).

you may also try using QOS-Optimize for Gaming. there should be that option on most linksys routers.

Skorpion9x · 04-01-2007, 07:02 PM

There are no QOS options. I don't see any way to cap his upload bandwidth either. And don't suggest talking to him to tell him when to download stuff (such as while those of us who have jobs are at work, or while we're sleeping), because I tried that and he just tried arguing with me. He's an inconsiderate prick and won't listen to what anyone says. He doesn't think he's the cause of the problem even though we know for a fact that he is (the other night, my other brother unplugged him from the router and afterwards was lag free all night).

**dieKatze88** · 04-02-2007, 09:46 AM

It also doesnt help that you have an AssRouter(tm)

Which is my name for any Router thats way too old to be still used. Get a WRT54G for 50 bucks, make sure you get a v6 or lower, and install DD-WRT on it (or, you can even send me the router, and Ill do it for you, but only if its V6 or lower)

That will properly support QoS for you, so you can easily lock your brother out of using 100% of the stream.

Skorpion9x · 06-12-2007, 01:54 AM

So I followed the advice here and got a new router, one with QOS options. The router i got is this one: D-Link DIR-625. Since we got this router, there hasn't been any problem really... until today. Earlier today, I ran into some lag spikes in WOW, which no one else experienced. So I checked the active sessions in the router and found my brother's IP address listed a bunch of times all with the source port #50453 (I've tried looking up information on this port, but found nothing). Anyway, after a few minutes, it cleared up. He must've stopped.

Now, late at night, it's happening again, and it's there a ton of times in the active sessions. So I tried messing around with the QOS settings, changing the priority for him completely to 255 (lowest) and myself to 1 (highest). It didn't seem to help. When I first looked at the active sessions, all of his stuff was 255, but refreshing a few seconds later showed the code below, a bunch of them started coming up at 128! I don't know if I'm doing something wrong or what. With him going like that, this website took minutes to load, so I cut his access off completely just to type this post, and I am also completely lag free on the internet and WOW.

P2P clients are not restricted to a single port. Newer BitTorrent clients usually make use of traffic obfuscation to avoid bandwidth restrictions. Restraining it (as opposed to just giving it low priority) might be a solution. Can I see a snapshot of your router's QoS configuration page?

Skorpion9x · 06-12-2007, 04:49 PM

Here's a screenshot of the QOS settings. It's actually two screenshots put together because I edited only the bottom two, that's why there are two scrollbars on the side

Try setting the game to high priority instead of setting torrenting to low priority

Skorpion9x · 06-12-2007, 09:37 PM

I set WOW's port, 3724, and internet, 80, to 1 (highest) and 2 respectively. I thought it worked because the latency went down a little bit, but it was green at the time, so not really noticeable. Right now, it skyrocketed, over 1500! This shit is practically unplayable. I couldn't even copy and paste the active sessions here because it's way over the character limit!

Here's a screenshot of what I did.

Your router is holding onto closed connections until a timeout hits. Youll need to reboot it.

Geschpooklichkeit · 06-12-2007, 10:27 PM

See if there are options for TCP connection timeouts in the advanced settings pages.

Skorpion9x · 06-12-2007, 10:59 PM

Don't see anything about TCP Connection Timeouts.

Skorpion9x · 06-13-2007, 05:19 PM

Cool, I just figured out that by copying and pasting the destination IP addresses to port 80 into Firefox, I can see which websites he's visiting! Now to just find a way to block those websites, perhaps in a tricky manner such as redirecting him to an antipiracy website; that would be awesome! However, quite a few of the ones I paste into Firefox come up with 404 errors and stuff. Any way around that?

Edit: found a place to find host by IP address. I found that one goes to bpath.com "Free Web Tools." I don't think he'd actual visit a site like that, so it's probably safe to assume it's a popup advertisement or something, right?

Edit2: ROFL I found one that came up "creativelink.net" located in Lithuania. I went to that address and found this:

"You have accidently mistyped the domain name.

Get out of here.

Yahoo | Altavista | Google "

Yeah, that doesn't sound shady.
