Re: High Pings and Ping Jitter with CGN3 and CGN3AC Modem

Thanks for the reply Aelph.

"rubber-banding", teleporting, sluggish game input, to disconnects." - this is what I experience while gaming at Aces High II. Very frustrating.

My modem model is the CGN3 from Hiltron.

Have two computers in my office, one hard wired.....and the secondary system is wireless.

I have the means of visually being able to see the "jitter" on my line, as there is a "Ping Test" option during the log in process of the game. When I run my "Ping Test" during the initialization of the.......both on my hard wired machine and on my wireless secondary system.........same erratic activity on my line.

To take it a step further.....last year when I was initially trying to get this fixed, I logged into my neighbors ROGERS connection. My neighbor did not have his wireless secured, so I connected to his connection and ran my "in game" test......same erratic behavior.

This indicates to me that the issue is not in my house...but further down the line. Problem is, Tier II folks escalate the issue up to their powers to be......and the reply I get is.. "not our equipment". Uggg.

Is there a firmware update for CGN3 model?

There currently is not at the moment.

 

The CGN3ACSMR model (the rocket one) does have a firmware update which fixes some MAJOR worse bugs.. but may also fix some other things.. its a newer revision, etc

Well it's been just under a year now since I reported this problem to Rogers and I'm still experiencing packet loss and high pings. Absoultely ridiculous.  Check out this screen shot of me pinging google.ca:

The only good thing is that they are crediting back all my internet fees. Really don't know what to do anymore. Maybe I should just go with Bell. Even though I heard their fibre is pretty bad too.

Re: High Pings and Ping Jitter with CGN3 and CGN3AC Modem

Hey,

 

On the 250u plan, but we're recieving very high latency / jitter which frequently occurs past 8PM although it may happen throughout the day.  The stats on the modem(CGN3ACSMR version 4.5.8.16) seem to be fine, so I'm thinking it's node congestion

Any ideas?

Was the speed test done via ethernet or wifi connection?  The signal levels and signal to noise ratios are all good, but the jitter in the speed test is ridiculous.  Can you run a ping test to the modem just to see what those results are like.  Bring up a command prompt and run:

 

ping 192.168.0.1 -n 20

 

To copy the results, right click on the title bar of the command prompt, Select.... Edit.... Select All.  Then right click again and Select .... Edit... Copy.  Then you can paste the results into the thread.  I would expect to see 1ms return times with possibly a random high ping over 20ms.  It should look something like the following.  I run my CGN3ACSMR in Bridge mode with an Asus RT-AC68U behind it.  So to ping the modem in this case I use 192.168.100.1.  That address would also work for the modem running in Gateway mode with a pc or laptop which is connected directly to the modem.

Ping statistics for 192.168.100.1:
Packets: Sent = 20, Received = 20, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 4ms, Average = 1ms

 

As you can see, the ping return times are not all 1 ms, as one would expect.  Firmware version 4.5.8.16 is a vast improvement in the latency to and thru the modem, but its not perfect.  Here's a ping test to www.google.ca:

Re: High Pings and Ping Jitter with CGN3 and CGN3AC Modem

These tests are done via ethernet. The jitter is pretty high past 8PM but for the other parts of the day it can vary between 10-20ms

 

The modem firmware is also the latest one available.

Jitter was 86 ms after that ping test.

Re: High Pings and Ping Jitter with CGN3 and CGN3AC Modem

That ping test is pretty typical for 4.5.8.16.  Are you in a house, apartment, condo, highrise, etc?  Have you called tech support to check the node which is what a home is connected to or MDU (Multiple Dwelling Unit) for apartments, condos, etc.

 

Can you post a ping test to www.google.ca as well, just out of curiosity?

House, haven't called yet. These tests are all done via ethernet...

Some of those ping times are pretty high.  Here's a comparison pinging the same address.  You must be using Rogers DNS, based on the ping address.

You might be on a node that requires splitting to reduce the load, and possibly, effects from any overloads.
