CODA-4582 Modem & DOCSIS 3.1 in North York area

I'm Here A Lot

Hello,

 

I am on the 100u Ignite package. Thinking about switching to the CODA-4582 modem. Is anyone using the CODA-4582 near the Keele and Sheppard area? Is DOCSIS 3.1 enabled in that area? Is the modem stable?

 

Currently using the 3552 modem, still find a bit of lag when playing games on PS4 (wired), so just wanted to see if now is a good time to switch to the CODA modem.

Hello, @tony2tran91

 

Welcome to the Rogers Community Forums!Smiley Happy

 

Thank you for posting your query in the Community. While you are waiting for the other members to join the conversation, I would like to provide the quick update that the DOCSIS 3.1 downstream deployment has been completed in your area. 

 

As for the CODA-4582 modem, we have about three active threads discussing various aspects like speeds, latency, lag etc., please feel free to browse them to make your decision;

The CODA with D3.1 is getting nice results, but the UDP issue is still not fixed, (It should be fixed soon as hiltron and rogers are working together to find a fix).

 

If you want to play safe, you can wait until that fix is done.

@tony2tran91 I would suggest getting the CODA 4582, Rogers is tuning the network for DOCSIS 3.1 going forward. Hitron and Intel are also going to be spending more resources on the new CODA platform rather than the old CGN platform.

By the way, learned Bell is having UDP problems in some cases, in particular things like majic jack and voice over IP - they have workarounds, but it won't work natively.

 

So as this technology goes forward, there are glitches here and there all around.  It really is still beta on the higher end stuff.

Keele and Wilson here. Coda 4582 is not stable, not wired even less when wireless. They have been working on fixes since 2016. Now i am judging it for the Gigabit package, maybe in your case with 100Mbps downloads it is a different story. Docsis 3.1 and IPV6 are activated in my area.

Hey there @tony2tran91, I'm up north in Vaughan and currently on DOCSIS 3.1 with the 100u package aswell. I have to say that D3.1 download has been stable quite for me. I've seen in speedtests that my ping was went down by (4-5ms) and if you do some gaming you can probably notice this decrease as well. Once D3.1 upload is enabled, you can expect your ping to go down a bit more.

 

In terms of maintaining the speeds that come with 100u on the 4582, I haven't had a single problem maintaining those speeds even during peak time. Download has always been rock solid and I usually maintain 130Mbps, that is, after having it speedboost to 200Mbps at the beginning of each speedtest. Maintaining 10Mbps upload has been no problem, but at times I could have it drop below it as my node is saturated on the uplink. 

 

I do avise you that there still some lingering problems with the CODA-4582 such as the UDP packet loss issue which can affect you if you do quite a bit of gaming. This UDP packet loss could be caused by this variable upload speed seen on the modem. However,  the packet loss is more noticable in latency-sensitive games such as League of Legends.

 

In terms of WiFi range, the range on the 2.4 band is good at the moment, but I am seeing that there still needs to be more optimizations made to increase the range of the 5GHz band. These optimizations should be coming in the next firmware version. I do want you to realize that the CODA-4582 can output more speed than the CGNM-3552 over WiFi because it has more antennas which are more powerful. 

 

Overall, I do reccomend that you switch to the CODA-4582 but I would wait untill firmware version 2.0.10.26 is deployed network wide as it seems to be showing really good results at the moment or wait 1 more month.

Thanks for the reply @RyzenFX. How has the CODA-4582 gaming performance been with these last few updates? Should be safe to switch to it from the CGNM-3552?

If you're a gamer then the CODA is the way to go. Latency is improved with DOCSIS 3.1, which the CODA supports.

 

Re: CODA-4582 Modem & DOCSIS 3.1 in North York area

Really ? I thought the udp was already fixed with the coda and 27 firmware , is there going to be a fix anytime soon ?

Re: CODA-4582 Modem & DOCSIS 3.1 in North York area

I think you will find that UDP performance has been greatly improved with the 4582 and V2.0.10.27.  I can run 500 Mb/s down, 50 Mb/s up UDP, without any missing UDP datagrams.  Above that, the missing datagram numbers start to grow.  You would probably have to run an overclocked Windows pc or maybe run linux to test the modems UDP performance to its limits.  I suspect that 500/50 is far above anything you will see for UDP capability for an XBox, PS3/4 or typical pc.

I find the cgn ignite rocket modem plays better with NHL 17 on the Xbox one it give me better ping then the coda

Re: CODA-4582 Modem & DOCSIS 3.1 in North York area

CODA with V2.0.10.27 loaded?  If that wasn't the case at the time, have a look at the following post and look at the ping time comparison between .26 and .27:

 

http://communityforums.rogers.com/t5/Internet/CODA-4582-Open-Issues-for-Investigation/m-p/393227#M44...

 

Those are simultaneous download/upload ping test results.  .27 shows considerable improvement over .26

 



Re: CODA-4582 Modem & DOCSIS 3.1 in North York area

Yea with .27 firmware ...ping was lower before I would get roughly lowest ping was 15 and highest 20 on the cgn modem but now on the coda I get anywhere from 19 - 29

Re: CODA-4582 Modem & DOCSIS 3.1 in North York area

Is that ping time to the CMTS or ping time to a target somewhere?

Nhl 17 shows us ping in game under network performance

@tony2tran91 I'm glad to say that the gaming performance of the CODA-4582 with firmware 2.0.10.27 has been fantastic. In my gaming sessions of League of Legends, Battlefield 1, and CS:GO I have noticed that my ping has decreased. With this also comes increased responsiveness and thus smoother gameplay. Having said this, it is safe to switch from your CGNM-3552 to the CODA-4582. Robot Happy

 

Firmware 2.0.10.27 was a big one to hit the CODA-4582 as it included a new Intel base code for the Puma 7 which dramatically reduced buffer bloat. Buffer bloat occurs when the modem is handling too much data and it has to drop packets in order to process the data effectively- this was to blame for the modem's poor gaming performance pre-2.0.10.27. Since 2.0.10.27 was released, a lot of users have reported positive feedback such as lower ping, dramatically lower buffer bloat, and generally more consistent performance. Since the release of 2.0.10.27 it has been quiet here on the forums so I'm suspecting the majority of the users are happy with their CODA-4582. 

 

Looking ahead on the CODA-4582, firmware 2.0.10.30 will include an improvement in WiFi performance (increased speed), and maybe increased range.

 

It's an all clear to make the switch to the CODA-4582. When you have the time, make the switch to the CODA-4582 and let us know on how it performs. If you do need help don't hesitate to ask for help from us as well Smiley Happy

@lethalsniper From what I know and have read, the UDP packet loss issue is to blame due to the poor buffer bloat performance of the modem on firmware versions pre-2.0.10.27. 

 

UDP packet loss is still seen on firmware 2.0.10.27, BUT that is because my node has high uplink usage (it's not the problem dropping the packets, the node is).

Re: CODA-4582 Modem & DOCSIS 3.1 in North York area

What do you mean you have high uplink usage on your node ? Your upload speed drops ?

Re: CODA-4582 Modem & DOCSIS 3.1 in North York area

In short yes, my upload speed drops because my node does not have enough bandwidth to handle all of the outgoing data. As a result, packets are dropped as the node tries to squeeze in more outgoing data.

 

Even if the upload speed goes down to 20Mbps, I still notice my ping increase in League of Legends from 25ms to 40+ms.

 

If the node upload speed drops down to 20Mbps on a daily basis, at that point Rogers should decide to segment the node or initiate upstream capacity uplift. It's ridiculous to have upload speeds as low as that now a days. Throughout the last 6-7 months, I have seen the trend that the upstream usage has increased by a lot. Rogers should be working to re-define when to plan for upstream capacity uplift, especially given the fact that DOCSIS 3.1 Upstream (OFDMA) is around the corner.

Re: CODA-4582 Modem & DOCSIS 3.1 in North York area

Yea that's the issue I'm having but only at night since December I finally got a call from the Pres of rogers and there is a fix on the way for my building from what I know the fix is by splitting the node and replacing fibre optic cables in some of our units in our building hopefully that fixes it ..
