FEEDBACK - Rogers Rocket Wi-Fi Modem Firmware Trial

[RogersMargaret]

Hello Community,

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.

So I have figured out that Windows Firewall is blocking IPV6 completely.   I cannot seem to find the correct rule to enable it to work.  Disabling it completely gives me a 19/20 or 10/10 depending on the site.  Anyone know how to fix this?

[Datalink]

@dmbcanda have a look at the following Microsoft Technet page to add a rule to the Windows Firewall:

https://technet.microsoft.com/en-us/itpro/windows/keep-secure/create-an-inbound-icmp-rule

I think I did that for both inbound and outbound when I added the rule.

Is anything wrong with my numbers? My speeds are always inconsistent, i’m getting 200-400 down and 10 up on a one black dot CODA running 2.0.10.24. Currently on the Rogers gigabit plan.

@gp-se It's Blackdot 1.... yeah it's a bit weird. Speeds have not improved and still around 300, although seems stable compared to before .24 but now don't know if the missing channels are Modem related. Also, don't know why it switched from receiver 0 to receiver 1. Is it because they replaced the Line-X/Amp on the steet tap, CMTS or the Coda issue. Below are the readings....I'll copy @RogersDave and hope he can comment.

looking at your SNR levels they are quite low, I would call Rogers and have them run some tests on your line and see what they say. The low Signal to Noise Ratio's are most likely causing your slow speeds.

[Windwalker]

@RyzenFX Thanks.

[trafsta]

@gp-se and others who have tried helping me in the past few weeks. I had a Rogers tech at my house as per your recommendation to troubleshoot the last 4 channels that were around -7.8 to -9.7 for signals and he isolated the bad cabling issue to some coax running from the outside demarc point to the inside demarc point (it went under the concrete flooring of our garage for about 20-30ft or so). I re-ran some quad-shielded RG6 cabling from the basement demarc through the garage walls/ceiling to the outside demarc (100ft cable, might trim it down to 60ft or so when I have the time to get a Rogers tech over to cut/trim and recrimp it - not sure if the extra 40ft or so would cause a bit of a signal drop at all)... anyways, the signal levels have dramatically improved. Thesea re the readings I am getting now on my CGN3AMR, please let me know how they look now:

[RyzenFX]

@trafsta It's good that you replaced the bad cabling, it was the culprit behind your poor signal levels. In terms of your downstream and upstream signal levels, they look really good. Your downstream signal levels are near 0, which is great. Howevever downstream channels 21-24 have a low SNR (Signal to Noise Ratio). I would call in a report this to the agent, and have it diagnosed. Other than that, everything else looks good.

[gp-se]

@trafsta the signal levels are looking more consistant now, but like @RyzenFX mentioned the signal to noise ratio isn't ideal. Give Rogers a call and ask them what they think of the SNR levels.

[trafsta]

The last time I called in the agent just kept talking about "no packet loss" and just ignored the signal levels on the modem that I kept referring to. I'll try calling again and will mention the faulty cabling has been replaced but that the last 4 channels still have bad SNR. Hopefully this next agent takes the SNR and signal stuff into account a little more than just ping results... (the last guy never even bothered looking at signal stuff).

I took the physical timer off the modem to stop resetting it daily at 3am. We shall see if it crashes anymore.

What could the bad SNR ratio on the last 4 channels cause anyways? Download speed inconsistencies? Still getting great speeds from what I can see 🙂

I'm thinking of going to get the CODA modem soon also so I can temporarily get away from ipv6 for the time being too... Haven't liked having to disable ipv6 on all my Windows computers for the time being. Also curious if DOCSIS 3.1 is in my area.

[trafsta]

I have also been meaning to ask about a "3db SAT4203 5-42MHz return path attenuator" that used to be connected to the coax input on my modem. I have taken it off now that I have fixed the cabling issue in my house. Any idea what that was for and what it did? Should I put it back? Might it help with the SNR for the last 4 channels perhaps?

Bad news for you: IPv6 was enabled on the CODA 4582 a few days ago... 

[trafsta]

Eeeeep... Any kind of firewall available on the CODA modems? My older model doesn't and all my Windows 10 computers were accessible via ipv6 after going to the trial firmware. Guess I'll read up on the new CODA firmware tomorrow.

[RyzenFX]

Yup, there's an IPv6 firewall. Just before releasing IPv6, Dave mentioned that there is an included firewall along with firmware 2.0.10.24. You can read more about it on his post here.

Very good postings from the link above regarding possible security issues with IPv6.

Majority of people in this forum are concerned with speed rather than possible security issues. IPv6 improves speed in many aspects from faster network games, instant web pages, even speedtest.net to servers with IPv6 like TekSavvy Toronto has improved drastically with ping time of 5 to 9 ms. Some streaming videos, web cams etc. have improved with smooth video and I'm sure that the rest of media streaming apps like Skype and similar are benefiting from it.

Blocking IPv6 or additional hardware firewall will slow things down to the previous level and the only 5 ms ping out there will be from local Rogers server test if you even see it. It's a trade off between speed and security. For residential networks speed will probably win since we are not talking about disabling security just speculating about possible IPv6 vulnerability.

For these special occasions when you don't want IPv6 un-checking this protocol in network adapter instantly solves the issue without even reboot. You can also reach any of you home computers and devices from the Internet without complex router ports set up just by typing new long IPv6 number. Very useful for Remote Desktop and similar programs.

Tech came today and replaced all splitters. As soon as they left for an hr, my internet disconnects me ever hr an so. First they said the disconnection is due to abnormal noise level, it seems not only just the noise level. Not sure anyone out ere experience the same disconnection issue.

Am I better with the Attenuator plugged in or out? Not sure if "Return path" means it is just changing my UPLOAD signal or something? *confused*

EDIT" Wait, a ton of the "Channel ID's" changed since 10 hours ago... is the modem changing to different channels that have a better signal? That may be why I am seeing better SNR on the last 4 channels now? Interesting...

I would leave the Attenuator in, since it's helping to raise your upstream signal levels. As for your second question, yes the modem can dynamically switch to better channels if needed.

Is anyone else having an issue with their modem (coda) rebooting more frequently than before? I'm on firmware 2.0.10.24 and this barely happened on the .19

I was doing fine on .24, but since IPV6 got enabled, every night my modem reboot on it's own.

Getting horrible download speeds this morning.   Rogers.com is not even reachable at points.  On Gigabit plan via ethernet on .24 Gateway mode:  I did a hard reboot and did not solve.
