Count me in as another person with the double reboot around midnight. I lost channel 18 though it came back after a reboot but the signal is slowly lowering again and I expect to lose it again.

Same with me, double reboot at midnight and now I'm missing Channels 18 and 19. 

Got this is my DOCSIS LOG:

RCS Partial Service

DOCSIS 3.0 Area, firmware .23

Never had any issues before this, signal levels haven't changed either. 

[hardretro]

Still so many issues....

I've lost quite a few channels over the last few days, as well as getting a lot of No Ranging Response, RCS Partial Service, and DHCP Renew errors. Rebooted a few times in the last two days.

I'm in a DOCSIS 3.1 area. Yonge and Eg

These are the channels I get before and after a factory reset:

Do you have the updated "Black Dot Modem" or an original launch CODA? The black dot modems have a black dot on the packaging, and a black dot on the modem itself near the power cord on the back.

The Black Dot modems have better shielding over the tuner to help with the missing channels. However in my case I don't suffer from the interference issue, so Rogers must be making changes to my Node/CMTS, which is why I'm missing two channels.

[hardretro]

@gp-se I am on the black dot modem. I swapped just over a week ago for this same reason, and was resolved until I noticed very evident latency and speed issues today.

[gp-se]

@hardretro I would call Rogers tech support and have them run some tests on the modem and ask them to check your neighbours to see if they're also missing channels. Perhaps they're making changes to your local CMTS, but call and see what they say.

[yyzsam]

I've only noticed one missing channel (#6)  once since i got the CODA-4582 and soft reboots didn't bring it back. I had to do a hard reboot aka pull the power cord, after that it came back.

[hardretro]

@yyzsam I've just done this, and yup, channels are back. Odd that a factory reset doesn't accomplish this. Anyone out there knowledgeable enough to advise why?

[JohnBeaudin]

Anyone know if @RogersDave will be back on the forums tomorrow?

[Alex4161]

@yyzsam and others

When it comes to rebooting the modem, I just find that unplugging the power cord and waiting a few minutes is the best technique.  Others have said that the reboot button in the GUI works but I am not entirely convinced.

I attribute this to the PC world of cold boot vs warm boot.  

GUI button press = warm boot.  

Unplug power and wait a few min = cold boot.

[tyreman]

My modem rebooted here about an hour ago. Odd did yesterday to at one time.

[gp-se]

When it rebooted did you notice if the Downstream LED on the front change to a lighter blue or purple colour compared to the Upstream LED? Rogers is deploying DOCSIS 3.1 so modems are going to reboot when the CMTS in your area is upgraded. 

[Mayoo]

I narrowed down the issue and kind of fixed it ( or dont know if rogers fixed it ) .. this is what happend in my case

I am on CODA Black Dot one and .23 FW was getting 400/30 Speed on Gigabit ..

I was on .19 before and no issues

1. If your using CODA as your Modem, then turn off the 2.4Ghz Wifi. Speeds came back
2. Here is the weird part. I was on Bridge Mode and then i turned off 2.4Ghz wifi ON THE ROUTER. Speeds came back ...
3. Once i found out workaround, 2, i ended up reloading the FW on my Router ( Asus AC87U with DDWRT-Merlin) I did a NVRAM Reset, Rebooted and now my Speeds are close to 850mbps ..

So below are some steps for members with no signal issues, channel drop issues but still getting low speed 

1. Reboot the Modem

2. Hard Reboot the Modem

3. Factory Reset the Modem

4. Turn off Wifi on 2.4Ghz Frequency on Modem

If you have a router then try the below

5. Factory Reset the Router and Hard Reboot

6. Do a NVRAM Clear as well  

[NLJ]

That could just be chalked down to using a third part firmware on the router.

[tyreman]

No I didn't notice,               There is a way I can tell from stats page correct?   You know what I look for ? Thanks

The point i try to reietrate is after every modem FW upgrade, we have to Factory Reset the Router FW as well .. Atleast that brought back the speeds in my case ... 

[AccordXTC]

@RogersDave has sure been quite, over a week and nothing mentioned. Could be a good thing or bad but ether way I wish someone from Rogers would keep on top and let us know whats going on in this epic fail.

I'm very curious to find out what you consider to be a soft reboot vs a hard reboot? There are NO reboot buttons on the modem or power buttons. The only reboot you can do is pull the power cord for 10 seconds. Not to confuse a reboot with a factory reset. The reset hole in the modem will perform a reboot if just pressed for a short time. If the reset hole is pressed for a longer time (20-30 seconds) it will perform a factory reset and the wifi will have to be setup again, as well as any settings you have made to porst, etc.

Just wanted to clarify this for the readers.

[yyzsam]

Pulling the cord isn't the ONLY option. There is a reboot button in the GUI. That's a "soft reboot". A "hard reboot" or "power cycle" is pulling the plug, or holding the power button down on a computer.

[borford]

OK, I was talking externally and there really shouldn't be a difference in that case as well. Glad that it did.

[yyzsam]

In theory there shouldn't be but....

@Mayoo

2.4 Ghz has been an ongoing issue since I reported the bug to @RogersDave over a month ago. 

This was mentioned as follows:

2.4 GHz WiFi Degrades speed

There has been reports in the last few days that disabling 2.4 GHz WiFi can make a difference on the wired speeds observed (by 200-300 Mbps). I suspect that this occurs on modems that are impacted by interference (which we are working on a replacement program in the next 2-3 weeks) but want to be sure that there isn’t another underlying issue.

If you observe this behavior and are available to run some tests, let me know. I will be looking for a case where cable signal is within specification and there are no sign of interference on your modem.

I would suggest you contact @RogersDave so he can run some tests since you have the updated modem with the interference issue fix.
