FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

I'm in Mississauga in a DOCSIS 3.1 enabled area btw.

I got the Coda 4582 black dot model today. It came with firmware 2.0.10.26T2 out of the box. So far, this modem is rocking. Played 4 HotS matches back to back and not one single disconnect or ping spike so far. This is significantly better than my older CGN3AMR on the latest firmware. 

Latency wise, this modem does much better than my old  CGN3AMR. Ironically, bufferbloat on this modem is considerably worse than the old AMR. Also, speed tests report higher jitter numbers on this modem.

send a PM to @CommunityHelps with the subject "coda firmware trial" provide you account number, modem serial number, and modem MAC address. The last two can be found when you log in to the modem. The latest .27 firmware offers huge latency and bufferbloat fixes.

@OL1v3r,

I've updated your MAC address in the trial participants lists and pushed the latest firmware to your CODA. You should see an improvement now.

Did a couple of tests after rebooting the unit. Jitter is significantly down compared to the previous firmware. Upstream bufferbloat is also improved (I don't think it went over 10ms during the test vs 600ms on the previous firmware). Downstream bufferbloat has not improved.

Glad to hear that uplink performance has improved, there was a lot of work done around that.

Regarding downlink, was it better with your previous (non-CODA) modem?

My current working assumptions are the following:

The CODA-4582 with firmware 2.0.10.27 is the best configuration we ever had in terms of uplink performance. Some users still have issues but it is likely caused by local RF issues / load and not the modem itself. This modem/firmware combination works better than any previous modem we had.

For downlink performance, there is really not much difference between our modems (although Puma 6 lineup tend to introduce additional delays).

Does it make sense?

I just noticed that I was updated to .27 and my performance has degraded pretty significantly from .26T2. I'm in Mississauga and on Docsis 3.1.

With 26T2 I'd get 900+ down and 30 up. On .27 I get 500 down at most and uplink seems to cap at 5-10 on most tests. 

Any insights?

Looks like you have some Port IDs missing, from 2-11. Reboot your modem and see if they come back, if not, do a PIN reset. If that doesn't work, you will need to swap out your modem. Unfortunately, when I had that problem, I had to swap out.

[ONeill88]

I factory reset and only channel 1 and 7 came back but 12 is gone as well now. 

Looks like I'll have to get it swapped.

Edit: Also noticed I'm back in 26T2 after the reset.

Just received the .27 firmware. Latency and jitter improved , but I lost about 100mbps down and around 10 upload. Webpages seem to load a bit faster though.

Can you post the details of the DSL reports test so I can see the current bufferbloat on this firmware for CODA.

Here is an example of mine running on the CGN3ACSMR on the .27 firwware.
