On Beta .24 I was getting 3days+ of uptime! but since the introduction of IPV6 it reboot during the night, not sure if it's related or if it's just a coincidence. I will continue to monitor.

Probably just a coincidence. A few days before .24 my modem was rebooting almost every night. I think Rogers is doing work/tweaking the CMTS causing the modem to reboot.

  If i remember correctly, IPv6 can be disabled in the wireless settings, for wireless devices and theres also some settings under Firewall related to IPv6. I been lucky i guess, all my devices work ok.

I have the same issue with my pixel XL. Frequent disconnects since IP v6 was enabled. Anyone have any suggestions to fix this



You cannot disable IPV6, even under the firewall settings you can disable http access, but the phone is still getting an ipv6 address.

Unable to browse websites while downloading.


I recently upgraded to the new Rogers Hitron CODA-4582 and while it is faster than the CGN3, I am unable to browse any website while downloading in the background.  I connect to Usenet and use about 60 threads and get around 95 MB/s which is a bit faster than the CGN3, but websites fail to load with the error "This website took too long to respond".  With the CGN3 I would get about 85 MB/s but websites opened in a snap and I could download files, with my Usenet speed dropping (this is how it is supposed to work) I looked in the 4582 and I don't see any options for QOS (I think that is what it is called) 


I have a fast computer with multiple Samsung 950 Pro drives. I don't use a router and am at a loss at what is going on.

Re: CODA-4582 - Open Issues for Investigation

Hello All


My purchased CGN3 modem died  a couple of days ago so I got myself CODA-4582.


Upon running it from the past two days I notice that compared to the 5 GHz band, the 2.4 is really slow (down to 10 Mbps at times. I get over 300 Mbps If I use 5 GHz!!


Is this normal?? I understand that compared to 2.4, the 5 GHz band has a shorter range but should they not be transmitting radio signals at the same speed?


I was not having this issue with the CGN3 that died.

CODA-4582 High Jitter, Poor Internet Experience

Hi all,


I have been encountering the same network issues recently, resulting in a number of CODA-4582 modem replacements. Some replacements are better than others but the problems generally remain the same. I have the Ignite 250u package, and my download speeds regularly reach max speed, however when I ping a website, or perform a speed test on the Rogers speed test page, I have jitter that varies from 4ms to 70ms+. I also appear to be experiencing packet loss. Often times this makes gaming or streaming a truly terrible experience as whatever I am doing will intermittently stop or fail, resulting in rubber banding or misfires in online games, and sudden stops in buffering/streaming. I've noticed that some other users post their DOCSIS WAN information, and looking over their information in relation to mine, it seems like my Upstream Signal Strength is lower than most of the other users.

Here is my information below:

Is there an issue with my upstream that could be causing my jitter and packet loss? If not, is there anything I can do to improve my experience? I am wired into the Ethernet port with the Wireless networks disabled. The CODA-4582 has firmware


Thank you all for your time.

I would like to add that all computers on my network have the same problem not being able to open a webpage while downloading.Too long to respond.jpg

Re: CODA-4582 - Open Issues for Investigation

I'm also suffering the same issue as you, jitter varies, sudden stops while streaming, and packet loss.

Is there some sort of UDP latency w/ the CODA 4582?

I currently have a ticket open srating that noise on my node is causing my upload speed to take a dip, aswell as jitter. It's very annoying during peak hours where noise is the most- and I have yet to get and update stating that they've fixed it. @RogersDave

Re: CODA-4582 - Open Issues for Investigation

While they are 'within spec', they are still in the low side.  Might account for SOME, but not all of the issue.

Where are you doing the speed test on? (rogers one or a 3rd party, and what endpoint server then)

And wired or wireless?

Re: CODA-4582 - Open Issues for Investigation

Same issue here on .24 firmware, high pings/latency all day , gaming online with Xbox one just horrible also we have to Xbox one consoles and one of them can find 5g but the other cant ? @RogersDave
