Hello TH community,
I'll try to be short and concise here. My internet is suffering from jitter issues. At first I thought that it was only the wireless connection, but last night my brother (who is wired into our router) did a connection test via pingtest and told me that the test showed a 10ms jitter. Whenever I do a test via pingtest I'll usually end up getting somewhere between 1-8ms jitter or even as high as a 20ms jitter.

Now I know that jitter may not have that tremendous of an effect on simple web browsing, but I play a lot of FPS games and that's where my internet's jitter hurts the most. I'll be playing CS GO for example and normally my ping to a specific server would stay at about 30ms. What happens is in random intervals (ranging from every 6-12 sec or a minute or so) my ping will flutter from let's say 30ms to 60ms, or 30ms to 80-120ms or sometimes as crazy as 30ms-230ms but will go back down immediately. It's just rapidly increasing and decreasing, but still causing annoying hiccups in my connection. I'll link a video to provide an example.

This jitter issue did happen for a period of a few weeks several months ago, but eventually went away, but now it's come back for its revenge. We did get a new router, and I got myself a new wireless adapter (a pci card this time) but both have not helped. This jitter issue occurs in Valve games, Killing Floor 2, and dedicated servers (so not just matchmaking) and pretty much any online game that I play

I have tried the following to fix my problem but to no avail:
-Restarting modem and router
-Restarting my own wireless adapters
-Unplugging home phone and wireless printer near my computer (is it interference?)
-Used my laptop to see if it was just my PC, but it happens on my laptop and my brother's wired connection



Not really sure at this point what else to look for, but I'm open to suggestions. Let me know if you require additional information that I may have forgotten!

Solution
10ms or even 20ms of jitter is pretty much just noise in the testing tools you can not really trust the numbers. Those small numbers will have no effect on games.

The ping times in the game are much harder to say since they are not actually ping and include overhead from the game client and server. You can have video setting set wrong and the game will blame the network.

You need to run actually ping test while the game is running to your router and then to point in the path to the server. You really need to test on wired the wireless will contaminate the results. The most common point of problems is the connection between you and the ISP

Regardless of the small number of the jitter from the test, it's still drastically affecting my games. Especially Counter Strike. I forgot to mention that my ISP is Time Warner, which is being switched over to Spectrum...perhaps this transferring over might have something to do with it?

Also, how would I point to the path of the server, by using the server's IP?
 


He has not tested it on any games since he hasn't played anything for weeks. I can hop on his computer and test some games to see if I get the same problems though. He did conduct a pingtest test and got a jitter of 10ms.

And just to put it out there, I've used pingtest for several years and I've never had any jitter on my connection, this is relatively new to me.

 


Understandable, its always good to try on a different PC and see if you get the same outcome though. If the problem shows on his PC as well there is nothing you can really do, that is unless your cable is running next to a 400 amp transformer. Anything beyond that its your ISP.
 


Apparently my bro is sick so I'll have to stay off of his computer for now. One thing we're gonna work on though is getting a new modem because we apparently have Time Warner's "Ultimate 100" internet package, which I would assume means a 100 megabit connection, but we only get 25mb, more recently 30-33ish. I think our modem is old and doens't really support anything higher than 25 or 30 megabits, so getting a new modem will be another solution that I'll try.

 


Yeah sounds like you have an old DOCSIS 2 cable modem.
