Re: Brutal latency/ping Recently

Mine all started with the whole stay at home thing.  I just don't think the infrastructure is setup to handle this many people.  It's fine for things like ignite tv and what not, but for gaming, you get way too many lag spikes.  When I play early morning or late night, it's completely fine.  If I try mid day or early evening, most games are unplayable.  I spoke with Rogers tech support last night and basically said, if the infrastructure can't handle it just tell me.  No need to try to fix something that's not fixable right now.


He did a few modem checks and checked the area and basically said ya, lots of people, high latency and a ton of packet losses.  Said he'd pass the message on to the engineers.  I doubt anything will happen though.

You would think a 600+ reply, 60+ page forum thread would get rogers to address these issues or atleast admit there is a problem

Re: Brutal latency/ping Recently

Alright here is a small clip I did today....This is not even as bad as it gets but its still bad.
Latency/Packet loss. I have the Coda-4582u Modem, 300Download 20 upload but my actual speed is 100/1 lol
My ping test to when it doesn't time out averages at around 100 with 200-300ms spikes

Some footage of me running around in Valorant.

Had a straight-up disconnect earlier. Found these messages in the logs. Can anyone elaborate on what I'm looking at here?

Re: Brutal latency/ping Recently

@herrshaun can you delete the CM-MAC data please.  That should be posted in an open forum.  


Looking at the data, yup, it looks like a disconnect, but, I can't ascertain any reason for the disconnect.  Depending you where you are located, and what the modem is set for in terms of time zone, that might be a 2 or 3 am disconnect at the neighbourhood node, or possibly a firmware update.  If it was a firmware update, you should see the download indicated in the log just before the disconnect.


Fwiw, over the last week, I've seen disconnects occur at my neighbourhood node, usually just after 2 or 3 am local time.  There's nothing evident in the log, but, there is most definitely a disconnect as both the internet and home phone were dead.  Rogers has been changing some aspects of its network, with no pubic announcements of what its doing, so, the disconnect could be part of that, or it could be just normal maintenance that occurred.

Re: Brutal latency/ping Recently

So it's likely that it was maintenance related in some way and not just a random disconnect? I don't know if the firmware updated or not, the version it's showing is

I googled the errors and in another forum, someone claimed that it was related to a damaged aerial/drop line (something I have suspected from the very beginning, but techs never touched it).

Also, I have edited the last post.

EDIT: It looks like the firmware version I have is from 2018, and a ping test that just finished had a max ping of 119 ms. They didn't update anything.

Re: Brutal latency/ping Recently

@herrshaun its really difficult to know if the disconnect is maintenance related or if its a random disconnect.  The timing leads me to think it was maintenance related, but I could definitely be wrong.  The crystal ball is in the shop for overhaul 🙂


When you have time, and the patience to do it, can you log into the modem, navigate to the STATUS .... DOCSIS WAN tab and copy the entire table under the "Downstream Overview" line.  Select or highlight the whole table, all the way down to the bottom right hand corner of the bottom OFDM/OFDMA section .... right click, Copy.  Then in a new post .... right click, Paste.  That should paste in the whole table.  Maybe the signal data might show if there's a problem on the go.

Re: Brutal latency/ping Recently

Their network has been running poorly from my perspective for awhile. Majority of people that only stream netflix won't notice, ever.


However, the issue has gotten really bad with the covid19 situation and everyone being home.


If I was a betting man I think Rogers is just buying time until the situation passes. The latency issue will still be present but will not be as bad as it currently is.


They're moving towards fiber.. I highly doubt they are investing in their cable infrastructure.

Re: Brutal latency/ping Recently

@Datalink if it helps at all, here is the output from my router's DOCSIS WAN page:

We've been experiencing the same issues. Normal tasks are fine but you try and go on a VoIP call for work, you only hear a word or two at a time from the other end.

We have a tech coming by tonight to look but not convinced that will do anything as they have been here for the same reason previously which wasn't resolved.

Hopefully, the table formatting sticks as it looks fine before hitting post...
