Re: CGN3 keeps rebooting itself

Yeah.. so I take it back. After a good 36-48hr run it's back at it again. Random disconnects during random times. I logged into the modem and from what I could read and understand it lost connection a few times during the day while I was at work. This is in my DOCSIS Log from the most recent disconnect:

And @RogersMoin I don't have any USB Wifi devices on our network at home

I looked in my breaker panel box, saw the cable coming from the outside of the house runs into a splitter (which seemed old). Replaced the splitter and voila!

 

 


Thank you for replacing the splitter, however, the quality of the splitter matters. I can arrange a tech to inspect the splitter and do the replacement.

T3 timeouts are not alarming in that log, it's normal operation. Thank you for the update regarding USB WiFi adapter. Please reply to the PM which I've sent. 

 

Cheers,

Re: CGN3 keeps rebooting itself

sooooo for the past month my modom has been rebooting by itself.. ive had 4 technitions come by, called rogers tech support over 15 times. 

 

one tech said its a power issue. so we moved the modom to a different location in the house. the problem still occured . - modom switched 

 

another tech came and switched the modom.

 

another tech told us theres signal issues "on the air" coming from our tv cable box so we disconnected it. and he swapped the modom. - the problem still occured.

 

modom was sswaped 2 more times...

 

sooooo 5 modms later, un plugging our cable box in the living room, changing the power adapter, doing whatever all the techs told us AND THE ISSUE STILL HASNT BEEN FIXED. this is unacceptable rogers. its been 3 weeks. 

We pay for gigabit internet from you guys, cable and home phone. we also have buisness accounts with you, we spend 1000's of dollars how can you guys take this so lightly.

Re: CGN3 keeps rebooting itself

Hi @devv1995

 

 

Welcome to the Community!

 

Did this issue start after you changed to the Gigabit modem? Or did  you also experience something similar prior to switching to the current modem?

Re: CGN3 keeps rebooting itself

First of all, I'm sorry to reply on an old page. My problem seems to be similar or maybe the same to the problems stated by the people above. My router would reboot by itself randomly 1-8 times day. I first thought the issue was the router overheating because it usually happens once or twice in an hour when I play League of Legends on my laptop while my brother plays the XBOX. Both of them are connected to the router through Ethernet cables. Whenever I touch the router or the router's plug, its slightly warm, but not too warm. 

 

Something I also noticed was my DOC SIS Event logs show critical, warning and notice priorities. There are usually a lot more but its only 3 because I decided to reset my router to see if it would do any good.

 

I would greatly appreciate some help Rogers!

Re: CGN3 keeps rebooting itself

Hello @Leon_Li,


Welcome to the Rogers Community Forums! Smiley Happy


An intermittent internet is the worst! Especially when you’re gaming online it can become a major nuisance.


If you are still using the CGN3 series modems we strongly recommend upgrading to the CODA-4582 modem. It’s much better suited for online gamers and provides the best available speeds. You can go to the Rogers store and swap your current CGN3 modem for the new CODA-4582. All you need to do is bring the power cord and some ID for authentication at the store. Click here to use our Store Locator Tool


Setting up the modem is a breeze but if you have any issues please send us a private message @CommunityHelps the next time you're online and we can take a closer look.

For more information on our private messaging system check out our blog.

 

Regards,

 

RogersTony

Re: CGN3 keeps rebooting itself

No replacing it with the different modem is not the fix. We are on our third CODA modem and it is doing the same thing.
We are at the point where the service will be cancelled.

Re: CGN3 keeps rebooting itself

 

Hello, @jberria

 

Thank you for joining and posting your concern in the Rogers Community Forums. I can certainly appreciate your position, the modem rebooting itself can be disruptive. Since you have replaced the modem already we can rule out the hardware issue. 

 

In the past, we have seen the modem rebooting itself when certain devices connect to the WiFi network. Have you noticed any such anomalies when your modem reboots?

 

Also, if you can log into the modem, navigate to Status/DOCSIS WAN and post the Downstream, Upstream and OFDM sections so that we can analyze the signal levels.

 

Thanks,

RogersMoin

Re: CGN3 keeps rebooting itself

Where is said list?
I have done everything that has been suggested in this forum.
It could not be a device as the modem worked just fine with all the devices I have in the house for months.
This happened before where the replacement would be fine for a little while then start rebooting in the evening, every evening.
We have had techs come in and nothing was wrong at their end. The wiring is fine.
The modem or the connection is the issue. Unless we have a tech in at the exact moment it happens or full monitoring of our line for 24 hours nothing gets done.
I have been to other forums and this is a regular occurrence that happens to others, regardless of the modem.
I also have the modem with the black dot, which was the last recommendation in a forum. The last two I have had were black dot modems.

Re: CGN3 keeps rebooting itself

I had the same issue. The modem is just rebooting every few minutes. The strange thing is this happened most times during the night after 9 or 10 pm. I m looking forward to seeing how to solve it.
