I been getting the same issue and call Rogers CSR twice and 1 technician came out and took out the splitter in my basement and install a power amplifier and he says is passive. Will help and not distort other output. Issue continue and call in again they ask I go swap out my modem to the new Hiltron Coda version and last night has the .19 firmware and still keeps dropping for a few minutes and comes back for a few more hours and does it again.

Below is a small example of the event logs



@sti2006  Where did you find the DOCSIS event log for your modem? Maybe my CGN2-ROG modem doesn't have it.  Lots of info to read from 2014 here on:  Intermittent connection - DOCSIS Event log displaying critical errors

Re: Internet Connection Issues - 2017 experiences.

Just for info, I am still getting interruptions from 15 seconds to 4 minutes.

Example of the duration from 9:42 to 9:46 today for the imap.mail.yahoo.com server I have been tracking.

Re: Internet Connection Issues - 2017 experiences.

I've set up SmokePing on a Linux box I have and it's set to do the following:

 

ICMP ping localhost, my wireless router and the Hitron admin IP (192.168.100.1) -- 5 pings every 10 seconds

ICMP ping to DSL Report's EC2 server - 5 pings every 10 seconds

EchoPing HTTP requests to web.mit.edu - 5 requests every 10 seconds

DNS request to Google Public DNS and my Rogers DHCP-provided DNS - 5 requests every 10 seconds

 

I checked my CODA-4852 event log this morning and saw a ranging error overnight, which appeared to coincide with some high latency and a few dropped packets. This couldn't have lasted more than a minute.

 

Other than that, SmokePing shows some increased latency and jitter with all remote hosts last night (nothing terrible, mostly staying under 80 ms) until about 1:30 am, then very consistent latencies (20-30 ms) from 1:30 am til this morning.

 

The latency/jitter I'd expect from a busy node and peak browsing times, so I'm not too fussed about that. But I'm still wondering about the occasional "hiccups" that coincide with the ranging errors in the modem's log.

 

I'll continue to keep an eye on things.

Re: Internet Connection Issues - 2017 experiences.

I get this error "SYNC Timing Synchronization failure - Loss of Sync" at 2:00 pm every day in my CODA-4582 modem log.  I think I had the same issue with my CGN3ACSMR but didn't realize that it occurred at the same time every day.  It's not a big deal, but what would cause it to happen every day at the same time?

Over the 11 days in December 2016 that I tracked the imap.mail.yahoo.com server connection I was able to capture the lost connection time which all seemed to be about 4 to 5 minutes in duration. There were others that were 1 minute or less in duration and the loss of connection did not happen at exactly the same time each day, but it was close. I am leaning toward some daily check or update on the Rogers IMAP4Rev1 server that is used for emails. It seems this daily server event changes the IMAP data which ultimately gives you the "Your IMAP  server has closed the connection" error. I cannot be absolutely sure as only one of my Rogers email accounts constantly gives me this error message. The other does not!  1 to 4 minutes is hardly noticeable so I am sure most customers just think it is a glitch in their application, not with the internet connection. I would still like to get independent confirmation that the imap.mail.yahoo.com server does go offline for approximately 4 minutes daily before the next step of raising a trouble ticket.

RIP Gigabit speeds.


Those speeds look reversed. Try the Rogers Speedcheck Tool under Help and Support -> Internet.  Depending upon your DATA  PLAN, Roger's will give you a modem that limits your speeds. I have a CGN2-ROG modem that advertises 5 Mbps download and 1Mbps upload. With Speedboost, I can get between 10-18 Mbps download which is good enough for me.

I'm actually on gigabit plan and issues started on Jan 3.

 

It's either the new CODA modem (which I switched around Dec 28-30) and/or some artifacts left over from last tuesday (Jan 3) outages.

 

Called rogers yesterday and the technical support guy said the work was completed in my area so everything should have been back to normal. But when he tried to connect to my router it would time out and he saw I had pretty bad packetloss. 

 

Nothing much has changed in the past 2.5 years besides the new Asus router I got 3-4 months ago.  I already had a tech come by around September that had fixed my signal strength and replaced my splitter and the cable wires.

 

So they have a tech coming over on Sunday and hopefuly he can resolve it.

Re: Internet Connection Issues - 2017 experiences.

The internet disconnect/server availability is still happening. 2017-01-11     9:58 to 10:01 and a bit.

Does anyone know if report this on  Rogers Outages  is useful?  Some people seem to report this type of information here, but I'm not sure what they can do about it.
