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

@catalano11 sorry, thats not the signal data.  It looks like the data posted here:

 

http://communityforums.rogers.com/t5/Internet/Intermittent-disconnects/m-p/427573#M53744

 

Can you copy that section of the DOCSIS WAN tab and paste it into a post.  The post above looks like a screen capture, but, a simple copy and paste, as you have done above , will paste in the text contents of the signal level table without having to resort to a screen capture.

@Datalink

just talked to dlink "It doesn't have Downstream chart in the router" i would have to get into modem. how would i get into modem if i am in bridge mode from rogers modem AC, to my dlink -859 router?

Re: Intermittent disconnects

@catalano11, ok, sorry but this will be brief as I've just lost a long response to your situation.  Your post was moved and my ongoing response was lost.  Yet again, another example of leaving the posts where they are instead of congregating them into a monster thread. 

 

1.  For a factory reset on the modem.  Depress the recessed reset button at the back of the modem for 30 seconds and release it.  That will initiate a factory reset and reboot back to Gateway mode.  Set the modem up, to a point, by using a directly connected pc.  

2.  Log into the modem, and on the STATUS page which is displayed, check for two IP addresses in the upper right hand WAN ADDRESS block.  There should be two addresses, one IPV4 and one much longer IPV6 address.  

3.  Navigate to the STATUS ..... DOCSIS WAN tab.  Copy the lower signal level table and paste that into a post.  

4.  Navigate to the BASIC SETTINGS .... GATEWAY FUNCTION tab and change the Residential Gateway Function setting from Enabled to Disabled.  Save the changes and the modem will reboot into Bridge mode. 

5. Disconnect the pc while the reboot is underway and connect it to the router.  Connect the router's WAN port to one of the modems LAN ports.  

6.  When the modem reboot is complete, you should have internet connectivity.  You should be able to connect to the modem, thru the router by using 192.168.100.1 unless you have deliberately set the router's LAN address to that address.  If so, you will have to change it so that you can access the modem by using that address.  That will allow you to check the signal levels at any time and kick the modem back into Gateway modem with its Gateway settings intact.  

 

When this is all complete, you should be able to access both the modem and router by using separate and distinct LAN addresses.  



Re: Intermittent disconnects

Ok, from what you're indicating, the modem was and is still in Gateway mode instead of Bridge mode.  Follow the above instructions, staring at #4, to kick the modem into Bridge mode when you're ready. 

 

Your signal levels aren't great.  The downstream should all be around 0 dBmV instead of being down around -9 dBmV.  The signal to noise ratios are at the bottom of the normal range which is 36 to 40 dB.  The upstream levels are elevated above their normal 36 to 40 dBmV range.  Failure point is 51 dBmv, 52 dBmV according to Rogers.  So, your upstream levels aren't at the failure point yet, but they're getting nearer to that point.

 

Despite that, your signal levels are still within spec, but, I wouldn't be satisfied with where they are. 

 

There is either an external cable and/or connector issue afoot.  So, you're getting fast dropouts occurring, at which point the modem reboots and the signal levels will look fine for a period of time after the reboot.  Call tech support and ask the customer service rep to run a signal check on the modem and let him or her know that your seeing service interruptions.  Don't know if you will see a tech after that discussion, but, if you don't, and this persists, put tech support on speed dial and don't hesitate to use it.  Call in multiple times per day if necessary and ensure that the complaints are recorded on file.  That will build a poor serviceability history in a very short period of time, which can't be ignored.

 

Also ask the CSR to check your historical noise history, and to check the neighbours modems as well in order to determine if this is a single line problem (yours) or if this is a wider problem, which will require a Rogers tech instead of a contractor tech, or possibly a maintenance crew.

@Datalink 

Thank you so much for the help means alot! i know there is an issue with the internet due to my connection dropping always and  i would like it fixed since i pay money for the service. i will call rogers and have someone sent to my house to solve the issue. thank you again for the help and knowledge.

Re: Intermittent disconnects

@catalano11 there's no guarantee that tech support will send a field tech as your signal levels are theoretically in spec.  However, you should not be seeing any service dropouts.  If you have a similar situation with Home Phone services, if you have that, or with pixelation on Cable TV or audio problems, ensure that the CSR understands that.  It would be much simpler if the cable and/or connector simply failed, as the failure would be much easier to locate.  At the present time, its a pain in the rear, not fully alive and not fully dead.  

 

The other issue is to decide to run the modem in Bridge mode with the router in full router mode, or, run the modem in gateway modem with the router running in Access Point mode.  In the last configuration, the modem is in charge of the network, in terms of assigning IP addresses, firewall duties, port forwarding etc.  So, it depends on where you want those duties to live, in the modem or in the router.



Re: Intermittent disconnects

@MichelleH are you making any headway with tech support to resolve your internet problems?

@Datalink

i have called into rogers and they have told me there seeing an issue but its on the street most likely. they would have to send an engineer not a tech to solve this issue. 24 to 48 hours i should receive a text msg telling me if the issue is solved and i should call in to let them know if it is. they will also compensate me until this issue is fixed. here are my readings today looks higher.

For about 2 weeks the internet randomly disconnects for no reason. We’ve had a tech come out and “fix” the issue and also swapped the modem, but still the same issue. At this point it’d make more sense to change companies

 

Re: Intermittent disconnects

Hello @jailengomes,

 

Welcome to the Rogers Community Forums! 

 

We appreciate you bringing this to our attention. Having a consistent and reliable Internet service is essential these days so we definitely want to do our best to get these intermittent issues resolved for you ASAP.

 

We'd like to review the notes from the technician that recently visited your home and run some additional diagnostic tests to see if we can determine what is causing the disconnections. Please send us a Private Message to @CommunityHelps so we can pull up your info and take a closer look at this.

 

If you are not familiar with our Private Messaging system please click here.

 

We look forward to hearing from you!

Hi.  This is my first (and hopefully, only) post.  I already mentioned this to a Rogers Customer Support agent and she passed this to the Technical Support Dept..

 

Like many people, here.  I too had many dropped/weak internet connections.  However, I just didn't know the source of the problem (which lasted many years), and neither did Rogers.  The technicians who came to my house (over the years) for service did their best in finding the problem, but it still persisted.

 

Recently, another Rogers Technician came to my house for the same problem.  He tested the modem and cable outside (and said that they're both OK).  He also shortened the Internet Cable to the modem (it was too long).

 

Before he left, he suggested that I get an Electrician to check the outlet (for which the modem is plugged to the power bar) next to the Internet Cable because the internal wall wiring for that particular outlet was causing electrical interference (which had been resulting in the aforementioned problem).

 

As soon as he left, I did a super-easy trick that took me under 30 secs.., I unplugged both the power bar (for my PC equipment and modem) and extension cord and plugged them to another nearby power plug outlet (away from the Internet Cable).

 

The Result ?  I now have a rock-solid (Fully stable) Internet Connection (both 2.5G/5G), no problems so far for the past two weeks.  My Internet service is  Ignite 150/15 (2-year contract).

 

As for the problematic plug outlet (next to the Internet Cable), it's no longer in use;  I simply covered it with duct tape (you can also use childproof plastic plug covers).

 

I hope that this helps anyone here.

 

Thanks for reading.

Re: Intermittent disconnects

still seems like theirs an issue but they keep telling me issue have been solved. i wonder if i get my modem pushed to the trial versions for gaming if that would fix my issues?   do these numbers look normal to anyone? also my WAN up time is different from my LAN up time. i have 150 ignite unlimited.

Re: Intermittent disconnects

@catalano11 can you delete all of the data above the "Downstream Overview".  For your own online security, the Gateway Serial Number, HFC MAC Address, and WAN IP Address should not be posted in an open forum.

 

Are you seeing service disconnects at all?  Although the downstream signal levels are well below the ideal 0 dBmV, their still in spec.  As long as the modem is operating normally, you could continue to operate with those signal levels where they are.  The upstream levels are above their normal 36 to 40 dBmV range, not at the 52 dBmv failure point that Rogers uses, but, half way in between.  So, still in spec.  

 

If you are seeing service disconnects, call tech support and lodge a complaint.  Do that as many times as you have patience for.  I would also ask the tech support customer service rep to run a signal check on the modem at every call and run the same check on your neighbours modems as well.  There is an ongoing problem, its just a question of whether its a single line issue (yours) or a wider problem that also affects your neighbours. 

 

Also note that the trial firmware will not solve a cable or upstream equipment problem.

Hello !

 

Can somebody kindly look into my numbers? These random drops are driving me crazy when gaming, I've been tolerating them by quickly turning on my WiFi Hotspot on my phone and using that while the system reboots which takes 3-4 minutes.

 

I'm paying for internet service and I can't deal with the random drops every day. It's getting extremely frustrating. Not to mention I've never gotten close to the full Gigabit speeds I'm paying for, but at this point I'd just like a STABLE connection.

@azar1 call tech support and ask the tech to run a signal check on the modem.  It shouldn't pass the signal check.  Next step is to arrange for a tech visit to inspect the external cable and its connectors.  You definitely have some type of cable / connector problem on the go, so, first step is a tech visit.  Ensure that the tech understands that you're seeing service dropouts.

 

When that tech visit is complete, keep an eye on those signal levels.  The downstream DOCSIS 3.0 signal levels should be at or near 0 dBmV.  The upstream DOCSIS 3.0 levels should drop to somewhere around 30 to 32 dBmV for this modem.  If you still see service dropouts, call tech support again, and again, as many times as necessary.  Put tech support on speed dial and don't hesitate to use it to register a complaint regarding yet another service dropout.  Sometimes this takes more than one tech visit to resolve.  Be proactive and don't hesitate to call in. 

 

The modem itself is running DOCSIS 3.1 on the downstream side as can be seen with the one active OFDM channel, so, those upper DOCSIS 3.0 channels aren't used.  But, they are an indicator that there is an ongoing issue with the external cable and/or the connectors. 

 

The log timeouts aren't a huge issue.  Their simply a case of the modem requesting a maintenance period from the Cable Modem Termination System (CMTS), and not receiving a maintenance period within the usual timeframe.  That doesn't necessarily translate to a modem problem, just a case that the maintenance request has not been honoured by the CMTS.  So, the modem logs it (unfortunately) as a critical error, and carries on to request a maintenance period once again.  That cycle will continue until the maintenance period request is honoured by the CMTS.

@Datalink Thank you for your prompt response. A tech is being dispatched tomorrow. I will keep you updated on the outcome.

I Plan to Stick Around

@Datalinkthe technician came over today and quickly checked the signal coming into the home and immediately said its very weak. He then went outside near the power meter and checked it there. Said the signal coming from the supply box is weak and he will have to run a wire from the supply box to my home. (Sorry if I'm not using the right words here)

He said he had to run a long wire, currently it's going over 3 trees and across into my house. He said this is a temporary solution and he'd note that in about 2 months another team would come and fix the cable underground to the home. I hope this will be doner sooner because the wiring job isn't too nice to look at and I'm worried the neighbors will complain since it's using their trees.

He then went inside and added a power adapter with a coax cable into a new splitter, not sure what that's all about?

The end result however has been promising. No drops at all today and steady speeds. Hopefully it stays that way and hopefully they're able to fix the issue in a way where we don't have a massive wire running on top of people's driveways lol

Edit: can't properly paste the modem data from my phone so I'll post that later on.

Hello all,

I need your guidance or help on this since this is driving me crazy..

I actually found really similar issue that was posted on 2016. 

http://communityforums.rogers.com/t5/Internet/Internet-goes-down-for-5-minutes-once-to-twice-a-day/t...

He apprarently was not able to solve the issue...

 

Long to short, I have no speed/latency/throughput issue while internet is up, however, when I push high usage  (mostlikely playing a game on PS4), it will likely drop the connection and restarting the internet.

 

I have called technician twice already.

First solution was replace the modem and second time was technician came to my place and replaced all the old adapters (not cable).  

 

Strangely enough, this only started happening 2 weeks ago. Until then, I had no issue whatsoever. 

 

Here's the logs from hitron.

 

Thanks for your help in advance!
