So a couple of things that I haven't seen anyone else mention -- your signal levels, although all within range, are more varied that I would like to see. -1.3 to +3.3 is a 4.6dB difference - that's small but not trivial. They're also not varied really according to frequency (from your full list). This tells me that you might have some wiring problems.


Also, you're on DOCSIS3.0 still.

@tonytoronto let us know how it goes I'm also looking to go back to the black modems for gaming because the coda at this present time is worthless for me.

its been well over an hour and i havent heard nuttin from the kids, so far so good i guess.

The router part not great, might put it in bridge mode and use my old Asus router for now.

What firmware are you on ,heard the .27 improves latency

@4kgigabitguy can you have a look at the following post and follow the instructions included.


Hopefully this will give me a little more info on the 5g settings for those users who are seeing problems on the 5g network. 

Thanks @Datalink , I switched the channel bandwidth & things appear to running smoother. I'm not seeing the same results I used to get with the Rocket AC Modem on 250u in regards to wireless speed tests on 5G....I used to always get above 250-300Mbps where now, things flucate between 150-250Mbps....I have yet to see 290 Mbps which I used hit pretty often with my old modem/package.....Any other suggestions or ideas on why this would be happening ?

Yea I am and do is a lot of other users I'm thinking of going back to the cgn3acsr

@lethalsniper If you do go back to the CGN3ACSMR, do you mind letting me know if you notice improvements ? What were you getting on wireless 5G speeds test with the CGN3ACSMR & what you getting now with the CODA modem ?

Probably getting the CGNM-3552 but will let you know, would there be any difference between the cgn3acsmr and the CGNM-3552 in latency/ping if both run on the same firmware?

Re: CODA-4582 - Open Issues for Investigation

I am fortunately not a part of this ongoing beta testing and constant ongoing issues - once one is solved, it seems that another comes along.


Is there any sign that this is coming to a stable resolution.  I haven't notice whether there is an update on the original status reports by @RogersDave  I do understand that technology often does not go the way we expect once it leaves the lab and gets into the wild, but are we getting close.


People have been asking me about Rogers speed versus alternative companies and speed, and I am now saying, that the high speed solutions are not stable on Rogers, although it is being marketed strongly, but you will notice that they are now marketing mixes of solutions of speed and bandwidth solutions, and are finally acknowledging that lower speeds like even 30Mhz with 250GB bandwidth is more than adequate for many users depending upon what you use, and speed is not the be all and end all for all users - that each person needs to assess their usage patterns, and things like stability, latency, speed, bandwidth are all factors, and their decision recently to provide only 2.4mhz wifi in the 30 mhz speed plans, means that the modem is basically unusable in high density wifi areas and you need to pay for a higher end modem - it is time for everyone to just say that the standard needs to be dual band for those who don't have the higher band on their devices, and the need for 5 in some areas and drop pure 2.4 wifi modems totally.  And maybe time to go back to a model of just pure modems without gateways, because many of us end up with routers in place for various reasons, or at least give the alternative.  
The third party providers, all provide either modem only, or choice of modem/router, or gateway.  Yes, it is more front end cost, but the life of a high quality modem is pretty good, in particular if you go dual band, multiple antennas, focussed directionality of signal, and get one at ac level to prepare for possibly of new devices.


Just wondering what the status is and are we getting close or not.  I have stopped following closely, although I am interested on a technical level, but it has been going on for a long time now.  Compliments for the persistent of the tech team and plugging forward, and the patience of beta testers.  I do hope that these modems with instablility issues are not being sold at the production level - that will create nothing but annoyed customers.  Let's not repeat the Navigatr escapade.

I know Dave is working hard to make our internet better, but I don't think they're working on the UDP yet, they are working on other stuff first, but hopefully UDP is next because it's a priority for me anyway 😉

Just a quick update on what is coming. I have firmware but I can't push it to anybody yet. All modems are currently forced on firmware as this was the only way to re-enable IPv6.


Later this week or first thing next week, I'll be in a position to upgrade trial participants to This firmware will include fixes for SSID special characters (name and password) as well as a fix for modem rebooting on their own. From what we have observed, modems tend to reboot when they have more than 10 clients connected to them.


For UDP, I need to take a live trace of the issue on my modem and that has been really problematic. I tried multiple ways to reproduce this issue and I don't see it myself. Next thing I need to try is torrents as it appears this was problematic. As soon as I have a proper debug trace, we should be able to push Intel and Hitron for a quick fix.

Re: CODA-4582 - Open Issues for Investigation

Thanks for the update Dave, as for the UDP issue, we can try to help Dave with any logs or pertinent informations if we can re-create the issue, I am sure that would help him. Let's work together to make our internet better 🙂
