This issue has been bugging me a lot recently. Whenever I am playing a multiplayer game like diep.io or Left 4 Dead 2, everything in the game stops for 1 seconds, starts again, and then does the same.

 

I thought my ping was the problem. So I went to Command Prompt and issued a ping www.google.com -t command.

 

Here is the result:

 

bab584a76bef4b20824b4236040d6ad2.png

 

I don't even know what to do anymore to fix this.

 

I have a Netis WF2419 Router and a broadband wired connection.

 

Here is my configuration:
Broadband cable from my DNS is connected into my router's "WAN" port, and I have another cable connected from "LAN1" to my PC.

 

PC Specs:

- OS: Microsoft Windows 8.1 Pro 64 bit

- CPU: Intel® Pentium® G620 2.60 GHz Dual-Core

- GPU: NVIDIA GeForce GT 610 1024MB DDR3

- RAM: 4 GB of DDR3 RAM

- PSU: Free Silent 500W Power Supply

- Motherboard: ASRock H61M-DGS R2.0

 

Here is a list of everything I tried:

- Resetting my router to factory defaults. Helped for a while then it started again.

- Changing my DNS to Google DNS. Didn't work. Tried OpenDNS. Still not working. Left it default. Still not working.

- Cleaning up my PC and doing a complete internet repair using "Complete Internet Repair" tool. Not working.

- Changed ethernet cables, changed ports they were connected in, still not working.

- Contacted my ISP and told them if this issue was on their end, they said everything was fine.

- Tried looking for applications who use my internet, nothing was found except for Skype and Steam, and those aren't the problem.

- Connected cable from ISP directly to my PC, still not working.

 

I am completely stumped. Any help would be nice. I HATE this issue.

First thing I would try is connecting your computer directly to the modem from the ISP. From there, try a speed test.

 

If the problem is the same, try a traceroute: tracert google.com and post the results. FYI to copy/paste instead of having to screen shot, right click somewhere on the text of the CMD windows and click select all then press enter. Then paste into a reply.

 

Also, you had a thread here about a GPU issue causing game lag. Could this be related to your problem in anyway?

Also that thread I posted, no, it turned out one of my power supply cables was stuck in the GPU fan.

 

I tried connecting directly to the Ethernet port on my motherboard, that doesn't work. Neither does changing cables or moving them in other slots.

"Tracing route to google.com [216.58.214.238]"

 

The IP is different for the tracert then the ping. Try tracert www.google.com or tracert 172.217.16.100. Also the latency needs to be occurring for it to show in the trace.

 

"I tried connecting directly to the Ethernet port on my motherboard"

 

Do you mean the ethernet from your computer goes into the modem? Or do you mean you have a second NIC and you tried the main one on the board? If direct into modem, try checking the signal levels of the modem at 192.168.100.1. If you want specifics, what model modem do you have? I know WF2419 is the router, but what is the modem?

No, I meant I have a cable from my ISP that uses PPPoE Authentication. I either connect that to my router or to my motherboard. Doing both makes no difference.

 

Everything about my router can be found here:

I have no modem.

"No, I meant I have a cable from my ISP that uses PPPoE Authentication."

 

Can you explain this in more detail? What does the ethernet from the WAN on the router plug into? It looks to be going into something else that is acting as a router. Connecting a router to a router is not good for performance and might be causing your spikes. Notice the first two hops have private IP's.  This means you are double-NAT, which makes match making in games difficult.

 

 1    <1 ms    <1 ms    <1 ms  192.168.1.1

  2     2 ms     2 ms     2 ms  10.0.0.1

 

"I have no modem."

A modem turns one kind of signal into another. They don't run ethernet lines on the streets, so the ISP has to be using something else(coaxial,fiber,wifi,etc) to get service to your house. The modem is what ever takes that signal and turns it into ethernet. Who is your ISP?

So when they set up my internet they basically went to the pole outside my house, put a internet box there I imagine, I don't know what it is and dragged a cable from that box (an ethernet cable) to my roof, into my room and from there I could either plug that cable into my router or my motherboard port. I plugged it into my router's WAN port and took another cable, put it in the router's LAN1 port and from there into my PC's ethernet port.

 

My ISP is called RCS RDS, a romanian ISP.

10+ years of ISP troubleshooting and have never heard of such a setup. Who is your ISP? What ever that thing is on the pole, it is acting as a router and possibly causing your latency issue.

Something like this, Idk how to explain it. It basically is the source of every fiber cable in the neighborhood

Do you mind telling me who your internet service provider(ISP) is so I can try to research how they work? Looking just at Romania, seems they use a micro-ISP setup.(reţea de bloc/reţea de cartier)

 

Here are some common ones:

 

RCS&RDS

Euroweb

Mediasat

UPC formerly known as Astral

iLink (acquired by RCS-RDS)

Intrabit

Ines & Fibernet

GTS Central Europe GTS Telecom (formerly known as KPNQuest Romania)

Lamit Company

 

I would suggest contacting them and seeing if you should be getting a public IP from the thing on the pole. If you are not, then your choices is to live with double NAT or find another ISP. It may not be causing the latency problem, need more data to isolate that, but it is still likely effecting performance.

 

As for the latency, are you getting the high latency in the ping before you do the tracert? Need a tracert when the latency is concurring to see where(which hop) it is occurring.

My ISP is RCS&RDS.

 

Right now the latency stopped fluctuating but I'll get back to you when it does that, and I'll get a tracert exactly when it starts again.

I looked through their support site but didn't find any manuals or instructions for your setup. Closest I could find was "Digi Net Fiberlink 100" which uses FTTB. If that is the case, your speeds are slow at 50-60Mbps when they should be closer to 100Mbps.

 

If you do have Fiberlink 100, then this says to use DHCP. Your router is taking a 10.0.0.2 IP from the street and turning it to the 192.168.1.x it(router) uses for your network. If rcs-rds allows more then one 10.0.0.x IP from street, you could put your router in Access Point(AP) mode and allow devices on your network to get their own 10.0.0.x IP's. This would get rid of the dual-NAT issue and may improve performance. I wouldn't try it though without passing it by rcs-rds first.

 

Hopefully the tracert will show more when you catch it.

I'm getting the speeds I wanted, 50 MB/s DL and 30 MB/s Upload, but mine are actually 51 DL and 57 Upload, which are better.

 

You mean use DHCP on my router settings page? Because I am using PPPoE to login with my user and pass they provided me. On my connection I have it set to "Obtain DNS/IP automatically".

 

And if I click on "DHCP" on my router settings my connection doesn't work anymore.

 

One thing I did is update my Realtek drivers from April 22 2016 one to July 24 2016 one, just now
