Internet keeps disconnecting

I Plan to Stick Around

I tried unplugging modem and 3rd party router.

This problem seems to happen more frequently. I am now entering the info into my phone (notes) - time/day of disconnection and duration.

It went down Tuesday and now today. I don't recall how long it was out last time. Maybe 30 min or 1 hr total?

I also use a wifi Smart TV.

It has reconnected a few times only to drop 5 mins (estimate) later. Sometimes the speed is normal but often, the connection is at a much lower speed suggesting a problem.

I am wondering if there's an issue.

Re: Internet Keeps Dropping

I Plan to Stick Around

I've set up simultaneous traces to and the first hop outside my house to see if the outages correspond. They do. When the connection to the Google DNS drops, so does the connection to the CMTS router. 

Re: Internet Keeps Dropping

I've Been Here Awhile

Another bad day on Rogers here in south Ottawa.  Probably a dozen random drops of about 10 seconds each - enough to drop the video calls.  Often, I can hear my other party talking, but they cannot hear me.  This is a 500 Mbps connection, in theory.   Problems started in Nov 2020.   This is VERY frustrating.  2 escalations to Rogers tech support and nothing changed.


Did Rogers change something in the network in NOV 2020?


We run an Rogers Arris  TG3482G with Boot version + Download version in BRIDGE MODE.  We use a Netgear Nighthawk for router and wifi in the house because it gets much better coverage.


So far I have tried turning off the QoS in my Wifi router - as per Netgear recommendation for high bandwidth connections. Nothing changed.


Also tried connecting via a hardwire Ethernet line to my router.  This brought latency down, but did not solve the drops. No change.


I suppose I will try watching me ping tests to the first hop in the Rogers network to see what happens next time I see a drop....


Suggestions welcome.



Re: Internet Keeps Dropping

Exactly same issue here - on the 4 th tech and probably 6 or 7 hours online chat
They just either don't know or don't want to say what is wrong
Drops all the ignite tv's here as well
Tonight they have said they will 'monitor ' the signal for 7 days and get back to me
Same as you I have to work at home so this wait and see approach does not work
I have a PeakHour4 meter on a Mac hooked to the modem and I can see it dropping out - maybe 10 or 15 times and hour - some longer than others
Have no idea how to get it fixed - Guess get a new provider

Re: Internet Keeps Dropping

I Plan to Stick Around

Exact same issue here for a few month now.  Same issues as most others here.  No techs have come on site as I have pretty much ruled it out being an internal infrastructure issue. 


Rogers suggested moving me to the new Ignite platform but they could not do so w/o a price increase.  


I've emailed OOP to see what they can do, but in the meantime, I hold hope that someone will notice this thread and escalate these concerns accordingly. 

Re: Internet Keeps Dropping

I've Been Here Awhile

NOTE:  if you are using our own router - I noticed that vendors are recommending that you disable SIP ALG (Session Initiation Protocol - Application Layer Gateway), which can be the source of drops for gaming and for Zoom meetings (probably MS Team and Webex too, I assume).  My router has this option under the WAN setting.  SIP ALG was On by default.   I have turned it off but too soon to tell if things are better.


Also - Rogers techs appeared in our neighborhood yesterday and started replacing gear on the poles.  They would not provide many details (when asked) but mentioned that the hardware was old (20+ years) and corrosion had reduced service levels by over 30% in the coverage area.  (Our older neighborhood). This would map to my speed test which NEVER get higher than 350Mbps for a 500 Mbps service subscription.


Lots of outages yesterday, but not change in latency.


Average latency to the first hop from my house was 21ms and average packet loss was 7.8% over the day!   


So far today the latency is still 21ms but the packet loss is 0.1% (which is much better). Also - my speed test is STILL not topping 300 Mbps (on a 500 Mbps service)

Re: Internet Keeps Dropping

I Plan to Stick Around

All, let me share what I gathered.  I was with a TPIA on Rogers for more than 8 years , rock solid connection, perhaps have less than a handful of issues that I had to call tech support which all turned out to be Rogers area wide issues.


Last Sept, to prepare for work and school from home, I finally upgraded from 30/5 to 75/10 and was sent a brand new docsis 3.1 coda-45 (no wifi modem only) and since that day, I got random disconnections all day around 4-5 times up to 10 times a day and only way to get back online is power cycle the equipment.  And you know this, of course the disconnects only happened when you are in those critical zoom calls.. 😞   .   


Called support many times, had 2 techs came out, both claimed that they looked at all the lines , they all looked good etc.  Made a very long thread on another forum and have tried all sort of 'community suggested' tips and tricks include adding a 6db attenuator etc... Tried a second coda-45 to make sure the issue is not caused by a faulty modem, then finally swap to an older docsis 3.0 coda3-35 modem (without OFDMA upstream). With the 3.0 modem, I experienced a lot less disconnections, instead of 4-10 times a day,  down to around once every 2 to 3 days and again during critical meetings and had to power cycle equipment. 


After much more researches, it seems like the fix for me is to join Rogers direct and hopefully the issue would be taken more seriously or at least have a better response time.   So, I did and glad to report that I have been up for about 9 days now without one disconnection (finger crossed still.. ) and the trick seems to be the Technicolor XB6 modem with the Broadcom chipset.   This wifi modem combo unit also has a very good range and ended up returning my $300 router I bought over Christmas with the intend to fix the random disconnects.  BTW, the tech who came to hand me over the XB6 modem (charged $29 fee for me to install my own modem..),  is the same guy who came the second time to check my lines...


The only potential issue is that I get very slow upload speeds during the day , had a couple of speedtest showing 0.1Mbps and found that I also have very high number in Uncorrectable Codewords... will deal with this when an actual issue occupies I guess, right now I am just thankful to have stable internet like I had been having before.

Re: Internet Keeps Dropping

I Plan to Stick Around

I spoke with the OOP today.


1. They will not discuss technical issues. Despite being the "OOP", they would not escalate this concern.  The only way was to do so through Tech Support. 


2. They will not offer me a switch to "Ignite" without increasing my costs, despite not getting any extra service (I don't count usable service as extra service).


So thus I am stuck in limbo with the rest of you unless I wish to bite the bullet, and pay Rogers more money to get on "the new platform". 

Re: Internet Keeps Dropping

I Plan to Stick Around

yep that's pretty much my experience too with OOP.


They don't care..

Re: Internet Keeps Dropping

I've Been Around
I keep loosing connection with both Ethernet and wired connections. Been going on daily for about 2 months. Have white koda hitron 5482with black sticker at back.
Tech support ran some tests but couldn't find any issues from their end. I replaced my modem last month and they recommended plug in my modem directly to wall instead of UPs or surge protector. No difference. I ran a ping test last night for half hour. No packet loss. Lost all connections a few minutes ago so I decided to take a capture of the wan settings below. Any advice is appreciated on what to do. Thanks

Re: Internet Keeps Dropping

I Plan to Stick Around

I'm also having this issue. I have the white CODA modem and have had it replaced twice in the last 2.5 weeks as my original modem died. I was talking to a tech support today who also told me that I might need to "upgrade" my Ignite Gigabit service to the "new" Ignite Gigabit service. They currently have my internet being monitored for outages but based on this thread and the fact that they told me that according to whatever they were looking at that it's been up for 4 days despite that I told them it went out at around 12:55 today.

They stopped trying to get me to "upgrade" when I reminded them that it wasn't just the Wifi connections going out but the wired connections as well. I can't wait for it to go out again and have to talk to someone else about how whatever it is they are doing isn't solving the issue.

Re: Internet Keeps Dropping

I Plan to Stick Around

I am on Ignite, and have the same issue.

Connecting my laptop directly to the modem via ethernet cable has decreased the problem's duration and frequency, but not made it go away. 

Re: Internet Keeps Dropping

I Plan to Stick Around

The conspiracy theorist in me says this is just Rogers way to force everyone onto the new platform at a higher cost. 

Re: Internet Keeps Dropping

For those having Internet Instability issue and suspecting OFDMA causing the issue I would like to share with everyone a successful case of resolution.


Like everyone here I started having 5-minute instability starting Nov 2020.  After a few unsuccessfully attempts with Tier 1 support and swapping the router, I asked to speak to a supervisor and was transferred to a Tech Support Manager in the North York office.  I explained him of my issue and pointed him to this forum that linked the issue to OFMDA implementation.  He acknowledged there are multiple customers with this issue.  


He was able to run tests specifically on the upstream frequency and pinpointed the issue causing my instability and dispatched technicians to my area to perform node hardening and frequency tuning at 2 of my neighbors to remove noise from the upstream frequency used by OFDMA.  Issue is now resolved as of yesterday and I have stable internet for 2 full days!


Hope this helps others having this issue as we know DOCSIS technology require sharing of frequencies with your neighbors and in my case the excessive noise from my neighbors' signal is the cause of my instability.





Re: Internet Keeps Dropping

I Plan to Stick Around


Is there any way I can reach the Tech support manager?
I've had a technician swap out my modem, and I've been with their support team on twitter, which say they see no noise in the upstream.

Re: Internet Keeps Dropping

I Plan to Stick Around

When you call re a technical problem, ask to speak to a manager. 

Re: Internet Keeps Dropping

Having identical issues. What region are you.

Re: Internet Keeps Dropping

I'm in the east end of Toronto.

Re: Internet Keeps Dropping

I Plan to Stick Around

Sounds like exactly the same issue I am having - I have been referred and an M1 ticket created.  9/10 this just gets closed almost immediately.

Had the modem replaced 3 times now - significant slow ping outs.  Horrible speedtests, 13 techs to the house (insanity), and this thread has hit the nail on the head.

I was told to hang tight (last Thursday) till Tuesday as maintenance will have resolved it fully by then.  If not to call back and have a technician sent out... (ugh).  

Re: Internet Keeps Dropping

@stuhome you have a DOCSIS 3.1 upstream channel (OFDMA) channel running. That is fairly recent as Rogers slowly enables OFDMA across the network.  This appears to be negatively impacting a growing number of customers. Have a look at the previous comment that I just posted.

Re: Internet Keeps Dropping

I Plan to Stick Around

@Datalink I just saw that and just called Rogers out on it, finally got through and they hung up on me.

Back in the queue to speak to a manager, oh there will be a lot  to pay for hanging up on me.  I read out exactly what you had written and they were silent... then said ok I'll put you through and beep beep beep call ended.

Thanks for the information 🙂

Re: Internet Keeps Dropping

I Plan to Stick Around

I just wanted to update the status as of Feb 1, 2021:
1. I was told couple months back that my node is congested and needs segmentation

2. Waited and finally got the ticket resolved, got SMS couple days back

3. The problem DID NOT go away, I lose connection daily since the first day I complained

4. Called the Support Line, was told issue is resolved

5. Complained that it is not resolved, and was offered to upgrade to more expensive plan so I will receive the black modem.


I wanted to tell Rogers one thing - I'm extremely disappointed with the service and with the way how I was handled in the first place.

I personally think it's outrageous to even offer me to pay more $$ for the problem that is not on my end!!!


I demand to replace the defective CODA 4582 modem with the new XB black modem FREE of charge because it's not my problem that Rogers cannot deliver the product they advertise.

FYI Coda modems are known to be faulty as they part of the massive PUMA chipset defect that is well known:



@ROGERS - please take responsibility and ownership!!!
