Default Ridiculous latency in online games

Hi. I'm not sure if this post belongs in this forum or the PC Gaming forum, so my apologies if it's misplaced.

I moved into my current house in mid September, at which point my roommates and I got Centurylink service installed. I was sitting at 56 ms on the dot for about a month and a half, bar any server side issues with the game. However, a few weeks ago I started having major issues with latency. Sometimes my ping is fine sitting at 56 ms like it always has, but fairly frequently it will spike to 180-200 ms in the middle of a game and stay there until I reset the router. Resetting the router fixes the problem for about 5 minutes, then it spikes again and stagnates around 200 ms. Tonight was atrocious -- I hovered at 500 ms for an entire game of league of legends, spiking up to 800 ms, obviously making the game 100% unplayable.

I've called Centurylink support 3 times so far, which has been completely useless. They tell me to reset the router, and when I tell them that that only solves the problem temporarily they offer to send a technician to my house for $85. No thanks.

I'm using a wireless connection, as running an ethernet cord from my roommate's room to my room is not feasible. I've heard Centurylink is particularly inefficient in their server routing, and I'm more than ready to switch ISPs if that will fix the problem.

However, I'm certainly no networking guru and I want to do everything I can to fix any issue being caused by myself before blaming the ISP. These are my tracert results for a NA League of Legends server:

If resetting the router resolves the problem (if only temporarily), the issue is likely on your end.

Since you're on a wireless connection, I'd suggest switching over to a wired connection for testing, and see if the problem persists.

If it does, you're probably running into some interference, and switching to another channel may resolve it.

If it doesn't, I'd suspect another computer in the network downloading or uploading something (and this can be any computer, including smartphones, tablets, etc.)

Yeah, I'm kind of leaning on the side of other people downloading stuff while I'm playing. I've asked most of my roommates if they're downloading when I experience lag, but haven't talked to all of them yet. Thanks for the reply.

It looks like the traffic is getting through your router and modem in 1-2 ms just fine. As long as it's consistently that fast through the first 3 hops, I doubt there's much a tech could do to help.

If you look at the line with "POS6-0-0.GW3.LAX15.ALTER.NET" in both cases you can see a sharp rise in delay from the previous hop (from ~170ms to 340ish in the first example and ~115ms to 285ish in the second). That's most likely the primary issue for your latency issues. That hop is probably well outside your ISP's network, unfortunately. It wouldn't hurt to call now that you have a specific problem to report, though.

Just make sure you do a traceroute before you call so you know you have an up to date IP address (152.63.112.105 in this case) and that it is a current issue with that location.

Traceroute is only useful as a performance diagnostic in a completely controlled environment, and even then, it's not that useful. Excessive latency on remote hops could be caused by transient bandwidth bottlenecks on the local network.

Right, it's important to remember that every new line is a totally different packet and that added latency can happen anywhere up to that point. However, if you run traceroute multiple times and the increase in latency is regularly on the same hop, you at least have a case for reasonable suspicion.

I talked to my roommates, and it turned out one of them was torrenting like there was no tomorrow. Asked him to lay off and my ping seems to have gotten better. However right now I'm hovering at 300 ping and my roommate says he isn't torrenting.

On the other hand, my other roommate is hosting a minecraft server on our network. I'm assuming this is taking up pretty much 100% of our upload, but would this cause high ping for me as well? I'm also getting ~.5 mbps when I'm paying for 20 mbps. Any ideas? Thanks

You know how your roommates claimed to have laid off the torrenting?

They lied.

I just went around to all of my roommates and watched them run a speed test -- they didn't have any torrent programs running in the task bar that I saw, and I really don't think they're lying. The internet went back to 20 mbps / 30 ms ping for about 30 seconds an hour ago, so I played a game of LoL, but as soon as I started it went back to hovering between 300-400 ms -.-. This is the most frustrating thing. I just want to solve this problem.

It's your friends.....
Are you paying for this service by yourself or are they pitching in?

Yeah, perhaps you are right. We're all pitching in ~$5 a month, which is pretty cheap. Still, I feel like there should be something specifically causing the abysmal latency and download speeds. My roommate runs his minecraft server all the time with no issues on my end, and all my other roommates are going about their normal internet activities tonight.

I talked to my friend who lives ~10 blocks away and also has Centurylink as his ISP -- he was sitting at about 90 ms latency and 6 mbps download (what he pays for), while I'm at 400 ms latency and .35 mbps download (about 2% of what I'm paying for).

If it really is just too much congestion on the network from my roommates, would upgrading to a faster provider be the solution?

Using nearly all the upload capability can bring the entire network to a halt.
Torrenting does the same.

What router do you have?

You could also log in to the router and see if you can change some QOS settings to favor your gaming.

If your buddy is paying for 25% of the bill, have him limit his torrenting to 25% of the internet speed.

Run QOS on your router.

Heck, make sure you're running one with enough horsepower and a stable enough firmware to handle your local load.

Tomato on an Asus or Linksys N router is probably your best option.
