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.

I'm having the same issue with this new firmware.22 all handheld devises work except my acer laptop keeps on getting disconnected never had issue with.21

Re: Intermittent disconnects

 250/20 disconnects / constant slow down

 
 I made some account changes a week ago, now on the 250/20 using the CGN3ACSMR. Since I setup the modem I've been having these constant slow downs or disconnects. Rebooting the modem will get me back up to speed most of the time, but it only lasts 5 - 30 mins, then slows down again.

Contacted Rogers, but the Tech says nothing he can do, since the speed check while chatting with him was close to 200mbps. Of course, 5 mins after I hung up the phone, it slowed down to 43mbps.

 

Any help in fixing this would be greatly appreciated.

Re: Intermittent disconnects

I Plan to Stick Around

Hi, I'm wondering if my signal levels are sufficent? I'm getting constant disconnects with a bunch of T3 and other errors on  my router logs for the past 2 weeks now. I'm wondering if it's my old wiring in the house that is causing this. However when I had the CGN2, it was not a problem (T3 timeout with reboot every 2-3 months) with the CGNACSAMR I'm getting one almost every night coming home from work.

Thanks in advance. Should I be talking to a tech person on the phone as soon ast disconnects the next time?

Re: Intermittent disconnects

@WBarras, you have a high frequency roll-off occurring on the downstream.  The signal levels start at almost 0 dBmV, and by the time you reach 621 Mhz, the signal level is down almost 6 dB.  So, that in itself isn't a good thing but, even with that, the internet modem shouldn't be dropping off line.  The signal to noise ratios are good.  The upstream signal levels are low.  Normally they are in a 36 to 40 dBmV range, but, the modem uses pre-equalization on the upstream, where the CMTS indicates to the modem what transmitted signal level is satisfactory so that the signal arrives at the CMTS with the right level and signal to noise ratio.  So, that makes the upstream levels a little more difficult to judge. 

 

You might be getting some very fast transient signal levels downward on the downstream that are too fast to display on that page.  That might account for the service drop outs.  The one way to see that is to load pingplotter and ping the CMTS to look for packet loss and any potential drop outs.  Let me know if you want to pursue that. 

 

If the service drop outs are long enough to last thru a call to tech support, then that is the best time to call them.  Don't reset the modem.  Let the CSR attempt to query the modem.  The question at that point is whether the problem is just with your cable line, or if it also affects your neighbors or if its a wider area problem.  So, don't hesitate to call tech support, every day and more than once a day if necessary.  Put tech support on speed dial and don't hesitate to use it. 



Re: Intermittent disconnects

Hi all,

 

I've been having intermittent dropouts with my Rogers internet and thought to turn here for one last chance at a solution before I try another provider. 

 

The problem: Sometimes the internet can be stable for weeks, then it will die 3-4 times in a few hours, or a few times within a week. All my devices, including those wired directly to the Hitron modem, are affected. Sometimes the internet will come back to life within a minute, other times it will take longer (up to 2 hours) and/or power cycling the Hitron modem. During the shorter outages, my Hitron often keeps the usual 'connected' lights on the front panel. Longer outages and the blue "up" and "down" lights go off.

 

I'll mention that we have fibre to the home. 

 

The various setups I've tried: In the beginning, I had a Hitron CGN2 (wifi disabled), with one computer and an Airport Extreme (bridge mode, no DHCP) both connected via ethernet cables. I moved this setup to three different cable outlets in the house (two were dedicated; no splitters). After a few months, I replaced the CGN2 with a CGN3. For a while, I tried using the CGN3 as both modem and wifi router (i.e. the Airport Extreme was completely removed).  Currently, I'm trying something different: the CGN3 is in Gateway mode (i.e. no DHCP/WiFi) and only the Airport Extreme (with DHCP/NAT/WiFi on) is connected to it. My intermittent dropouts have occurred during all of the above configurations.

 

Rogers has visited twice: once to re-terminate all the cable jacks within the home, and a second time to replace the fibre-to-cable converter in the basement. Friendly techs both times, but no relief with the problem.

 

The CGN3 event page reports "no ranging response received - t3 time-out", and it appears to be around the time of my outages. However, some outages will happen without any events appearing in the logs of the CGN3. It's in bridge mode now so I'm not sure how to access the CGN3's internal web server anyways. 

 

Yesterday was a particularly bad day - the internet kept dropping - so I left "ping google.com" running in a Terminal window (Mac) on a comptuer connected via internet. Over five minutes, the packet loss was ~36% (usually, it's 0%).

 

Any help would be appreciated. Given that literally everything downstream of the fibre optic cable has been replaced at this point, I don't think there's anything left for me to try.  Oh - throughout ALL of this, our Rogers TV service has been perfectly fine, and works even if the internet is down.

 

Thanks!

Sam

Update: This problem continues to persist. (It is certainly not solved, even though this thread is marked as such.)

Re: Intermittent disconnects

It is marked as solved, as its another users initial thread, and their issue may have been soved.

 

 

I am not sure how many users here are familiar with fiber direct... i am not sure overall how different it is..
Though it appears to be using the same modems, etc... so i would assume most of the other stuff is the same, its only the delivery.  (so the troubleshooting on the fiber line itself would be different than cable, etc).

 

Are you able to log into the gateway and post the signal levels at a good time and a bad time? Just to see if there is anything there which may be amiss.

Re: Intermittent disconnects

Hi Gdkitty,

 

I can't login to the Hitron currently as it's in 'bridge' mode and there's no access to 192.168.0.1 (I think I read elsewhere this is a bug in the firmware).

 

Last I recall, the signal levels were -2 dBmV down and 38.5 dBmV up. I can say that every time I've called a CSR and they've tested my signal levels (whether my internet was working or not),  the CSR has said both up and down are within acceptable values.

 

Sam

 

PS - I'd intitally created a new thread, but my post was merged into this one. Does anyone know of a way to mark it as 'unsolved' again?

Re: Intermittent disconnects

Yeah, when bridged, your own router, etc.. will take usually be your gateway at 192.168.0.1 (or whatever you have it set as).

 

Depending on what your model is.. (as some firmware seems to permit it and some dont) some of them you can access the gateway via 192.168.100.1


Was just asking, as if there is a DROP durring the Bad times.
But generally for good times, that strength isnt horrible if fairly consistant across all the channels.

Re: Intermittent disconnects

oogabooga007
I Plan to Stick Around

Hi Gdkitty,

 

Thanks for following up. No, there is no drop during the bad times; the strength is indeed fairly consistent across all the channels, and in both good and bad times. 

 

I've read something about "CMTS" issues but I don't know enough to say whether it is perhaps related to my woes.

 

Sam

Re: Intermittent disconnects

The CMTS is something at the local head end.. sort of where the modem registers to.

There have been CMTS changes recently, with them changing to CASA instead of cisco.. but generally shouldnt be causing what your happening.

 

Unless its just droping the registration or something.. that the cmts is having issues in that way.

Re: Intermittent disconnects

oogabooga007

Thanks again Gdkitty. I picked up a Cisco modem this afternoon, so let's see if it can fair better than the two Hitron misses I've had thus far.

Re: Intermittent disconnects

WBarras
I Plan to Stick Around

Hey @Datalink sorry for the late reply. It suddenly stopped not working! 🙂 Unofrtuntely for the past week it's been off and on again (not as badly but more than normal I would think)

 

Ever since then, my roll-off has been better on the downstream, reaching 300ish Mhz vs. 621. Upstream is still low as you said, hovering around 30-33 dBmV range. This correlates with a few changes I made to the wiring sytem in my house. I haven't changed the actual wire, but I have replaced a few splitters which were unknowlingly in positions that were better catered to couplers (I used splitters for those instead of couplers) Silver ones if that make any difference. That obviously changed my timeout situation for the better, but not my upstream.

 

I have an old splitter (only one now) that is rated at 5-1000Mhz. Is that sufficent or should I be looking at higher ones of the 2Ghz range? It's also silver plated vs the gold I'm seeing at Best Buy and the Source. So far it's good! But if it comes back, I might look into the actual cable replacement and a tech visit. Thanks in advance again.

Hello,

 

Exact same problem for me as well, my internet have been disconnecting atleast 3-4 times a day and it last for roughly 30 secs. I have swopped modem and the samething is still happening. I nothiced this issue occured when there was a issue with Rogers back on October 27 (case number C116716310). I called Tech 3 times and they couldnt find any issue but to tell me to unplug the modem. I live in a Condo, so I guess the lines run accross the whole building. 

 

I have the CGN3ROG router and here is my log ( not sure what it means), hopefully someone can shine a light.

 

Thanks

Re: Intermittent disconnects

While your signal is a little on the low side, they are technically not out of spec..
But they do still look a bit out of wack.. 

 

That it lists 3 upstream channels... but the channel ID and frequency is out of wack.

This is definately something you will need to call in and have a tech sent out.

Re: Intermittent disconnects

I am trying to figure out what is causing my modem go through these changes... for some reason during certain hours .. there isn't a specific time frame the modem stats spike and there is a big difference in variation .

 

When the jumps happen my internet starts behaving differently, and more t3 errors start showing up in my modem log and hiccups in the internet where things dont load.

Upstream seems pretty consistent on both days:

Re: Intermittent disconnects

Both of those are within spec.. and still pretty close to the good point.. that i wouldnt think that DIRECTLY is the issue your having.  Its only when you start getting close to/above +/- 10 that you really start seeing a bunch.

Question is, what is causing the varriance?

Does this happen randomly durring the day? Or does it seem to happen more at a specific time?

Randomly.. could be something like the connector outside the house is going (with the weather, etc).

More specific times.. i am guessing its more of an area issue.  When more people are on, etc.. that something cang handle the strain, and then your seeing signal changes... as well as possible OTHER issues at the local node, etc possibly, which may be causing the problems.

From what I have gathered, it seems to happen between 2-7 sometimes 9 and the stats drop off again to "norm"

But on lets say weekends i've had it all day until midnight .

 

So it could be an "area" issue , or maybe something going on at the tap, 

 

They are within spec, but there is a variance between the lower to highest and back down.. like some channels jump and others remain .

 

I don't know to be honest.. there have been periodic slow down and ping spikes but nothing huge

I am also having similar issue, my wifi for 2.4/5g is very unstable. Below is the event log, not sure what they mean, but i see alot of "errors", "no range response". I got a tech coming this friday, but does anyone know whats going on in the mean time? Thanks

I Plan to Stick Around

I started noticing this problem in Ottawa a few weeks ago.  Saw somewhere that the Rogers supplied DNS seems to have software bugs so I manually set my DNS servers to Google 8.8.4.4 and OpenDNS 208.67.222.222 and the problems seem to have gone away.

I also believe this problem might have resulted in "inflated" internet usage...

This has been happening in our neighborhood for years. Most people have stopped complaining because it's such a hassle to call in and wait through the authentication process, automated menu, too-loud musical hold, etc. The local techs who've investigated and changed modems, connectors, lines, community boxes, etc., have been great, but haven't been able to fix the problem. I believe the issue is NOT local, but further up the chain of head-ends and feeds. This affects TV, home phone and Ignite Internet. It is particularly bad for YouTube, which drops out to the main screen. TV just freezes, loses audio or drops pixels for anywhere from 1 second to 30 seconds. Home phone drops calls in progress. We pay over $200 a month for our services ($2,500 a year plus) and are constantly embarrassed when guest are over and ask, "What happened?" when a music video fails on Qello, YouTube or a program freezes on Netflix. I just tell them we're on Rogers, and that the service is intermittent and has been for years. One tech person told me, "Hey...we're not perfect!"
