@lethalsniper As he mentioned, it will start during spring b/c it will require permits and a lot of digging in order to split the node. You can't really do much other than wait for it to be fixed.

@RogersDave

 

Has there been a fix to the issue where I keep losing the OFDM Downstream channel rendering my modem as being offline from the Rogers network?  I have this happening 2 to 3x a day and the only fix is to unplug, wait a few minutes and replug the modem to reboot it.  This is really annoying and has started from last week.

 

I called support and they eluded to the fact that I may have a signal problem and I have a Sr. Tech coming to check things out tomorrow morning.

 

Here is my current signal levels and I power cycled the modem aroung 7 pm.

Okay fair enough but @RogersDave what's causing the high ping and jitter as you see in that image

Congestion on the uplink will cause high ping and jitter.

I have a question for everybody with very unstable connection (I know this is a vague definition) but looking at really slow downlink speeds (below 50 Mbps) or serious UDP problems.

 

Can you tell me how many devices (both wired and wifi) are connected on your network?

 

When I try to reproduce some of the UDP issues, I only have a single device on my test modem and I'm wondering if that has an impact in my inability to reproduce the issues you are facing.

@RogersDave  I'm having UDP problems & I can help you test - particularly serious since .24 on downstream RTP (VoIP) traffic.  My MOS scores are constantly dropping to 2's now on .24

25 devices wired & wireless - split across multiple VLANs on business-grade hardware.

Re: CODA-4582 - Open Issues for Investigation

I seem to be having more and more issues with streaming now. Major latency and some packet loss continues.

I reset the modem after the spikes there at the end which seemed to fix it but the latency was still terrible (up to 150ms) - and that started at hop 2 (the modem).

@MegnaGaming

 

I think your logs from Twitch could help @RogersDave to reproduce the UDP issue so he could work a firmware fix.

Re: CODA-4582 - Open Issues for Investigation

Modem lost sync last night according to logs, woke up to alerts on my cell telling methat my remote monitoring software lost connection to my servers i monitor.  investigated and my IP v4 changed. so fixed that up on my backends.

 

Internet was still acting foolish so i did a reboot of the modem and im not on DOCSIS 3.1

 

Weird, it mush be havign a hard time locking it as I assume thats what the reboot overnight was for, and it didnt grab it first time. 

 

 

Will test today.

Awful Upload speed and the Download is not much better when I was getting 940Mbps most of the time.
