Re: Brutal latency/ping Recently

Hi,

 

My internet recently has been starting to have insane ping spikes that makes playing videos online virtually impossible. I can't play a single game of league without lagging out and i've literally tried everything. I've had a technician come out, maintenance department came out, and still no resolve.


I have a hardwired connection to my Hitron C3GN modem on Rogers Gigabit Package. My ping constantly stays 120 or above and its brutal playing any game. I have a Cat6 ethernet cord connected directly to my PC.

 

see snippit of Docsis Wan below

Re: Brutal latency/ping Recently

Hello, @zRa.

 

Thank you for posting the Downstream, OFDM and Upstream signal levels; high pings can impede online gaming experience. 

 

The signal strength for OFDM and Upstream looks good, besides online gaming, have you noticed ping spikes in any other application?

 

Can you please follow the Internet Knowledge Base article Troubleshooting Latency (Wired Devices) and post the ping & traceroute results to google.com and your gaming server? The results can help us to isolate the issue. 

 

Regards,

RogersMoin

Re: Brutal latency/ping Recently

Hi,


I'm in Ottawa (K2J) and for the last 2 months everyday I hear my kids complaining about internet connection when they are gaming online (fortnite and minecraft).   Both PCs are wired connected using Gb cables.   They get disconnected from their online gaming servers.   Regular browsing, downloading and watching netflix seems to be fine.    I'm using modem in the bridge mode connected with an Asus 1900p router running latest Merlin's fw.      I run some simple ping tests to check for packet loss, but I haven't seen anything.    I've tried rebooting CODA modem (7.1.1.32 fw) and my router without much luck.    My kids think they need to buy new PCs to fix this problem.     Can someone please check my current CODA stats and tell me if they look ok.   Also please let me know if I can conduct any tests to troubleshoot this problem.

Re: Brutal latency/ping Recently

My lag spikes are back. I had the issue at the beginning of Feb 2020. That lasted almost 2 months. Not for the last 2 weeks, I started to lag in games again. Last time the issue "fixed" itself because Rogers never fixed anything after all the visits and customer support. I really can't keep dealing with the internet like this. My Phone LTE is better to game.

Re: Brutal latency/ping Recently

Hello,

 

I have been having constant ping spikes on my ignite gigabit connection for a while now (over 1000 ping on some occasions) and I average around 300-400mbps when running speed tests on ethernet.

I am running my Technicolor CGM4140COM in bridge mode connected to a pfsense router (dual core 4 thread i3 with 8GB RAM) and a tp-link gigabit switch.  I have tried connecting direct to the Rogers gateway with the same results.

 

I would really like to get this resolved as gaming is almost impossible when the connection is spiking and the download speeds are less than half of the rated speed.

 

Thank you!

Welcome to the Community!

 

Your Downstream signal levels actually look pretty normal but they only tell part of the picture.  If the Rogers network is introducing latency, it could be happening in the "CMTS router"... and nothing out of the ordinary would show up on your downstream or upstream signal levels, error stats, or in the modem's Events log.  You would need to perform additional tests to localize where latency spikes and/or packet loss is occurring and those tests would also need to rule out anything on your side as the cause.

 

I don't use pfSense and I certainly don't mean to bash it in any way.  However, if you search the Internet for pfsense "ping spikes" , you will get a bunch of hits where other users are describing pretty much the same issue that you are seeing, including the 1000 ms ping spikes.

 

You mentioned that the performance issues also occur with a direct connection to the Rogers modem.  In that case, I would take your XB6 out of bridge mode, connect a computer directly over Ethernet, run your tests to confirm that the performance issues still reproduce consistently, and contact Rogers Tech Support to report the problem.  Get them to check the signal levels to your modem, noise levels in your area, check the loads on your local node, and check for other possible problems affecting your area.  You can also send a private message to @CommunityHelps  to report the problem and ask them to investigate and open a ticket on your behalf.

Re: Brutal latency/ping Recently

been having this issue for about 1 year and 2 months now, words cannot describe the frustration i have built up on this subject.
