Intermittent disconnects

I've Been Here Awhile

I've been having intermittent disconnects lasting ~30 seconds on weekend afternoons ever since I got the Ignite 100 package last summer. It happens on ethernet and wifi, no matter what I'm doing (surfing, streaming, video calling, etc).

 

When I initiate a chat support session, the signal is usually good and there is no packet loss. But the issue continues soon after -- perhaps every 15 minutes or so.

 

I've tried swapping the modem, the technician has replaced something outside my house, and I've tried swapping the modem a second time, but the issue hasn't gone away. Rogers chat support has opened an engineering ticket on March 19th but I was told via chat support today that they have closed the ticket and found no issues.

 

However...! I have gathered some proof. I have started to keep a log of of my modem's signal levels and noticed that the upstream channel 3 signal strength goes up from ~40dBmV to >50dBmV whenever I'm experiencing the intermittent disconnect issue. I also see the following DOCSIS event message: No Ranging Response received - T3 time-out;

 

Here are the signal logs I've kept over the last few weeks: https://drive.google.com/folderview?id=0ByfHiW1x8WuXbHVvRmg5QjhCWVk&usp=sharing

 

How can I get this issue resolved? I would rather have slower speeds if it meant that I could have a constant reliable connection. As it stands now, I get good speeds but I can only enjoy it 70% of the week.

Re: Intermittent disconnects

@jooooka1 call tech support and ask the Customer Service Rep to run a signal check on your modem.  That check should fail automatically, followed by a conversation to get a field tech out to your home. 

 

Your downstream DOCSIS 3.0 channels (1 to 32) are all low, with slightly low signal to noise ratios.  They should all be at or very near 0 dBmV with a signal to noise ratio of 36 to 40 dB.

 

You have two OFDM channels which are running, which is new.  Typically we only see one channel running.  Two is the future, so, its nice to see Rogers making headway with this.  No doubt, the signal levels are also low for those two channels.  Unfortunately, the signal data isn't shown in the user interface, so I can't tell you if those channels are running normally, but, I suspect they aren't.

 

The upstream levels aren't not too bad.  They are higher than normal for this modem.  Typically we see somewhere around 30 to 32 dBmV, so, you're levels are still well within spec, but higher than normal.  That would be the result of whatever problem exists with the external cable and its connectors. 

 

Can you delete the CM-MAC and DOCSIS Overview table from your post if you read this in time.  After three hours the posts are locked and only a moderator can change them.   The CM-MAC address and DOCSIS Overview IP addresses shouldn't be posted to an open forum. 

 

Where are you located?  Just wondering given the presence of two OFDM channels. I'm wondering if that data is correct or if its a result of the poor signal levels?

CGN3ACSMR Modem keeps disconnecting randomly

 

Hey all,

 

I'm hoping I can get some help in regards to my internet. I've been having issues for about 2 months now and lately it has been getting worse and worse. Long story short I keep getting disconnected from the internet for about 30 seconds maybe 5 to 6 times a day (I've looked at the modem right when it happens and the '@' sign starts flashing or the upstream and downstream turn off). I've actually had two tech specialists come to the house but because of COVID they can only check outside and they said the issue was too much signal (they added a splitter and changed modem twice) but it still happening and it is actually getting worse.

 

what could be the issue? I am hoping somebody can really help me out this time because this is getting frustrated.

I am just adding my signal to see if everything checks out okay here. is it looking okay or could it still be an issue as I had a tech come and checked the signals and said it was fine. ALSO! i there is no OFDM Overview under the DOCSIS WAN tab on my router webpage.

Re: Intermittent disconnects

@pizzamber your downstream DOCSIS 3.0 channels (1 to 32) are higher than I'd like them to be but, you should be okay.  You're just at the point where historically, users start to see issues with high signal levels.  The DOCSIS spec is + 15 dBmV down to - 15 dBmV, but, typically users start to see issues long before the extreme ranges are reached. 

 

The upstream channels are what I would expect for a black Hitron CGN3xxxx modem, which normally run in the 36 to 40 dBmV range.  The odd issue here is that you only have two upstream channels, instead of three or four.  Where are you located?  There is one area near Hamilton I believe which was bought out by Rogers, from Shaw (?).  I've seen another recent post where there were only two upstream channels provided.  If you're not in that area, then you have some issue afoot as there should be more than two upstream channels running.  The signal levels don't indicate any issue associated with just two channel running, which is odd, but, that depends on where you live.  

 

What modem do you have, a black Hitron CGN3xxx where the modem model is seen on the product sticker at the back of the modem, or, the white CODA-4582 modem?  There is only one white modem in use with Rogers.  IF you have a black Hitron modem, can you specify which modem it is, as indicated on the product sticker.

Heey there @Datalink ! thank you again for helping me out with this.

 

My location is in Mississauga close to the eglinton and hurontario area.

Actually right now i decided to check my DOCSIS WAN again and its only showing me one upstream which is 

Upstream Overview

the modem that i have right now is the Black Hitron CGN3ACSMR and I am still getting issues where my internet goes down maybe for 30 seconds then comes back up. I've noticed the '@' sign sometimes is off when it happens or either one fo the arrows facing up and off or not blue or green. Don't know if that would make any difference.

 

Once again thank you so much for helping me out with this!

My internet drops for 10 -15 seconds every 15 minutes at exactly the same times to the second.

When the time changes to 12:00 to the second, the internet will drop, then at 12:15, 12:45, 1:00, 1:15 ..... and so on.

I have talked to Rogers tech, they have come out and replaced the cables outside, done tests still the same.

Got a new modem as suggested, still the same, another senior tech was dispatched and they are not able to figure this out.

I am testing this out by connecting my computer directly to the modem with an Ethernet cable no WiFi involved.

Re: Intermittent disconnects

Good evening @oliu202020,

 

Intermittent disconnects canm be incredibly disruptive to say the least. We appreciate you providing us with the steps you took so far and thank you for giving us the opportunity to assist with your internet issue.

Internet is garbage I have had this for 4 weeks now and I have had 8 calls and 2 tech come out to tell me there is nothing wrong my internet drops twice every hour and have to wait 10 min for it to come back this is so frustrating and shouldn’t happen for a new service I have 1gig download speed and might get 50mbps at best
Please fix your internet if anyone is thinking of switching to this ignite DONT

Re: Intermittent disconnects

Having the same issues. My Rogers internet disconnects very often for 30 - 60 second intervels. As far as I can tell, this is relegated to just WIFI. I've had not connectivity issues when plugging directly through LAN cable. I've tried firmware upgrades, etc but to no avail. Details below. Please help!!

Re: Intermittent disconnects

Hello, @Balistixx.

 

Welcome to Rogers Community Forums!

 

Thank you for joining this discussion; undoubtedly, the WiFi devices dropping the connection for brief periods can be inconvenient. It's helpful to know that the wired devices are not losing the connection. 

 

Where is the modem located? For optimal WiFi performance, this modem should be in a standing/vertical position above the floor and enough clearance around it. 

 

Do all the devices disconnecting from the WiF network? When was the last time the WiFi network was stable?

 

I look forward to hearing from you!

 

Cheers,
RogersMoin

Re: Intermittent disconnects

@Balistixx 

 

Which modem are you running? It must be an older model since it only have 24 channels. Are you renting the modem or do you own it? If it's being rented I would suggest swapping to a newer modem. Also have you tried a factory reset on the modem?

Re: Intermittent disconnects

In the last several weeks on some days I was losing an Internet connection for up to 1 or 2 minutes quite a few times a day. It seems that WiFi is OK during these outages.

I have: Hitron CODA-4582U modem, Software Version: 2.0.10.36T8

Re: Intermittent disconnects

@Yury_mak call tech support and ask the Customer Service Rep to run a signal check on the modem.  That will fail automatically as you appear to have severe cable and/or connector problems.  That will lead to a discussion to have a tech visit your home to check the external cable and its connectors.  

 

1.  Are you in a house or apartment/condo/highrise?

2.  If you're in a house does the external cable run underground to a nearby pedestal which should be visible from your front yard, or does the cable run overhead to a nearby utility pole?

 

 



Re: Intermittent disconnects

>> 1.  Are you in a house or apartment/condo/highrise?

           Single family house.

 

>> 2.  If you're in a house does the external cable run underground to a nearby pedestal which should be visible from your front yard, or does the cable run overhead to a nearby utility pole?

     External fiber optics cable goes into my house.
     Then there is a small box that has a coax cable as an output.
    Then my Hitron modem is connected to this coax cable.

Re: Intermittent disconnects

@Yury_mak it looks like you have Rogers Fibre to the Home (FTTH) which probably looks like this:

 

https://forums.redflagdeals.com/rogers-rogers-cable-retentions-new-customers-deal-thread-read-thread...

 

From what we've seen in the forum, the fibre installations are probably pretty reliable, but, their not infallible.  We don't actually see many complaints but they do happen.  

 

Next time that you have problems, call tech support and indicate what you're seeing on the modem in terms of missing channels or poor signal levels, but, key point, also mention that you're on an FTTH system.  

 

The only thing that the FTTH system does is replace the traditional copper cabling that runs from the neighbourhood node to the local tap to your modem.  Its still a DOSCIS system, running over fibre.  

 

I would think that the tech would also have to check the fibre terminal to determine if there are any issues with the fibre feed.  It should have its own set of signal parameters which should indicate whether or not the fibre signal was within specs.  The fact that the modem has poor signal levels could point to the fibre terminal output, or perhaps the neighbourhood node if in fact what was seen at the output of the fibre terminal reflects the output of the neighbourhood node or perhaps the fibre cabling itself.  The fibre system also brings with it its own set of potential problem points.  So, tech support has to recognize the fibre optic portion of the system and diagnose any potential issues with it.  

 

The question at this point is whether or not the average front line Tier I service rep has the experience and knowledge to tackle FTTH system.  That I don't know.  It would be worth a comment from @CommunityHelps.

Re: Intermittent disconnects

Hello, @Doxy.

 

Thank you for posting your concern in the Community; micro disconnects can be tricky to diagnose.

 

I appreciate you posting the log and signal levels; they are within the acceptable range and should not cause the disconnects you are experiencing. Is it happening on both the wired and WiFi devices?

 

Do you notice your modem rebooting when the connection drops?

 

We look forward to hearing from you.

 

Cheers,

RogersMoin

@RogersMoin 

Yes the disconnect is happening both on wifi and wired.

The modem doesn't reboot. It's kinda a micro d/c 10-20 sec most.

Then everything is back to normal.
