Latency EXTREMELY unstable on the new Gigabit package

Before my switch to Rogers, I was experiencing packet loss during peak hours. The ISP determined that we were having issues with the node in the area (oversaturated). Nevertheless, my latency to the outside as well as the modem were extremly stable. Now, with the switch to the 1GBPS plan from Rogers, my latency is absolutely everywhere. Here are some ping graphs:


Ping to modem

Ping to outside

You can see the crazy unstable latency on the right hand side -- it's literally everywhere.

Anyone else have this issue, or anyone know what I can do to fix this?

Re: Latency EXTREMELY unstable on the new Gigabit package

You're not the first person to notice this.  Other users have seen this come up ingame and in VOIP applications.  I've switched to the CGNM-3552 as well and my ping time to the first node beyond my modem has gone from an average of 10 ms enroute to anywhere to something between 20 to 30 ms on average with high ping times ranging from 200 to 300 ms.  My graphs look very similar to yours.  I'll be sending an email to the engineering staff pointing out the fact that users are really starting to notice this now.  Have a look at my post #76 on the following page and have a look at some of the linked graphs.

Re: Latency EXTREMELY unstable on the new Gigabit package

Yup, looks like we're definitely having the same issue. What's the likelyhood that they'll get this resolved? I can see this being a pretty annoying issue while gaming.

Re: Latency EXTREMELY unstable on the new Gigabit package

@Mathooshan can you have a look at the product sticker at the back of the modem and let me know what it happens to be, CGN3, CGN3ACR, CGN3ACSMR, CGN2, or DPC-3825.  

 

In the case of the CGN3 series modems, can you log into the modem and let me know what Software (firmware) version is loaded, as indicated on the Status page that comes up after logging in.  Finally can you then navigate to the STATUS ...... DOCSIS EVENT page and have a look for one of the following sequences:

a. CMTS-MAC=00:17:10 which indicates that you are connected to a Casa Systems Cable Modem Termination System (CMTS), or;


b. any of the following which indicates that you are connected to a Cisco Systems CMTS.

 

     1. CMTS-MAC=00:05:00
     2. CMTS-MAC=00:12:43
     3. CMTS-MAC=00:14:f1
     4. CMTS-MAC=00:1f:ca
     5. CMTS-MAC=e0:2f:6d Note: there may be other Cicso MAC addresses
                                                             as well which are not on this list yet.


Please let me know if you have the CMTS-MAC=00:17:10 sequence in your DOCSIS EVENTS log as you will need to request the trial version 4.5.8.21 if you are connected to the Casa Systems CMTS, which that sequence indicates and you happen to have a CGN3ACSMR.

@JohnyR you should request the firmware as indicated in that post as it resolves the issue of dead LAN ports when connected to a Casa CMTS which you will have.  

 

I will be chatting via pm or email with the engineering staff about this issue.

Re: Latency EXTREMELY unstable on the new Gigabit package

@Datalink Here it is:

CGNM-3552

Firmware: 4.5.8.21 (firmware trial)

I am definitely on the Casa CMTS (00:17:10 in logs present)

Re: Latency EXTREMELY unstable on the new Gigabit package

Thanks, you're a step ahead of me.  Unfortunately I have no idea when this will be resolved, but, I'll be bringing it up with the engineering staff.

Re: Latency EXTREMELY unstable on the new Gigabit package

Yeah, I just hope they take it seriously.

 

If you ever need any sort of data, ping graphs, ect. please let me know. Here's another MTR that may help when you speak to them http://i.imgur.com/xs04OEw.png

Re: Latency EXTREMELY unstable on the new Gigabit package

@Datalink

 I Have the CGN3ACSMR with 4.5.8.20 firemware version. 

I cant find any of the CMTS-MAC you listed .

Re: Latency EXTREMELY unstable on the new Gigabit package

I'm getting crazy 8% packet loss right now to the node. Anyone else?
