We are currently offering our users an exclusive opportunity to participate in an upcoming trial of the new firmware for our Rocket Wi-Fi Modem (CGN3ACR, CGN3AMR and CGN3ACSMR) and Rocket Gigabit Wi-Fi Modem (CGN3552 and CODA-4582). For details of this program, please see this thread.
This thread will be used for feedback regarding the firmware. We've invited @RogersSergio, @RogersSyd & @RogersBob from our Networking team to participate in this thread. Your feedback is very valuable and will be used to enhance the firmware before it is released publicly.
Thank you for your continued feedback and support.
The ODFM (Orthogonal frequency domain multiplexing) profile is the modulation definition used by each device to pass traffic on the cable network. Depending on this setting it would increase or decrease the amount of traffic that can be passed. As you'd expect the higher the modulation the more data can be passed.
When we introduced D3.1 we only had one profile... so like D3.0 we only pass traffic at a specific QAM (Quadrature amplitude modulation) level. Depending on noise on the plant we are constrained on how high we can set this value so when we have a single setting we need to aim for the lowest common denominator.
With the multiple profile support we will be able to set various thresholds within the device and as impairments are encountered the devices can automatically adjust to ensure you are getting the best performance. With any network we are always in a constant battle with noise and how to mitigate it's impact on your service.
I'm hoping this answers your question... if you are looking for a more techy response let me know and I can see about getting you one.
I know a number of you have asked to have your devices upgraded but I am not going to be able to upgrade everyone right away. There is a network side update that also needs to be completed which may push out your upgrade date a little.
I will keep an eye on the network side updates and get everyone signed up as testers upgraded as soon as possible.
With that said, some of you may know that as we approach Sept network/device updates slow down a little because of back to school. Typically this wouldn't impact rolling out the test code to our tester base, except this time we are tied to the network changes.
So far performance in speed tests showing perfect speeds. Streams default auto quality to 1080p & no longer seeing down scaling to 360p. This version is definitely back in the right direction.

Thanks for getting us back on track hopefully it gets pushed out to everyone asap.
These you done are on the new firmware for the AC modem? It's very promising hopefully it will fix that issue on the CODA, everytime I watch twitch if on autoplay it goes to 360p and if I force it in higher res it will cut for 2-3 secs every 2-3 mins.
This is on the coda modem with the new firmware 220.127.116.11T2
That is exactly what I am talking about it fixes the downscale of quality on twitch. It locks into 1080p fairly quickly and the most iv seen it go down was 720 at one point.
My modem went off the night before so I'm assuming a network update was done in the area.
@mcsandy ran the puma6 test, not all green like yours, but maybe a minor improvement? it's possible the CMTS for my area isn't updated. or maybe my signal levels aren't as good as yours, and that's affecting it. the DSL connection I have here is 100% green, no weird latency spikes. I'm definitely on the 18.104.22.168T2 firmware for the CODA too.
I knew you would call me out as soon as I posted that note 😉
In an attempt to get you the more techy response I would like to clarify what should the focus be on?
Are you looking for info on D3.1/OFDM or more about how it's been implemented at Rogers [keep in mind there is only so much i can share :)]
