Wanted to add a data point.
Running 22.214.171.124 on CODA with gigabit plan, in bridge mode with ER-X router (had to enable hardware offload for NAT otherwise I was getting about 450 down, also had to remove a rogue cat-5 cable from the mix).
Everything seems to be better than I would have expected.
@Lumute your downstream signal levels are high, but within spec. The signal to noise is ok. The upstream signal levels are fine. The only thing that a tech would do is install an attenuator to drop the downstream levels. That would also push up the upstream levels. if you're not having any problems I would leave it alone for now. Over the next few years, without any changes, those levels will drop on their own as the external cable and connectors age.
Thanks @Datalink, I am on Ignite Gigabit and my speeds are top 500 Mbps / 25 Mbps but fluctuates a lot and normally lower than that... To be honest anything above 150 Mbps on the download side is good enough for me, although I should be getting speeds that match what I pay for I am ok with waithing for them to deploy DOCSIS 3.1 to correct that issue later this year.
That said, due to the work I do from home the upload speed is a much more critical to me. If I were to install that attenuator so the the upstram levels get improved, would that improve the upload speeds? I somehow think the problem is they oversold on my area so maybe only 3.1 can fix it... is that attenuator something I can buy and install myself or should I call a Rogers and ask for a tech to do it?
@Lumute you can find attenuators online, but honestly, with your signal levels where they are, its not worth doing. It won't increase your upload rates. I suspect that the issue is as you indicated, oversold capacity. The question at this point is whether or not these low rates can be resolved with DOCSIS 3.1 on the upload side alone, or, whether it will require node splits. DOCSIS 3.1 on the upload side is still weeks or months away. From what I understand its still in development.
All cable systems are built on numbers. For example, X number of homes in a neighborhood will subscribe to a given ISP, of which, only some, Y homes require service during the day, and Z homes will require service during the evening hours. I think the numbers are all estimates, however by now I suspect that cable companies have this down a science. Crunch the numbers and you come up with an estimated throughput requirement for a CMTS. I suspect that the arrival of internet TV (Netflix and others) along with much higher internet speeds are throwing some of those calculations out the window, leading to unhappy subscribers. How that can be answered is up to individuals such as @RogersDave to determine. Maybe he can shed some light on what seems to be a dilemma for a growing number of customers.
I have been getting horrible speeds on the gigabit service, 150mbps download and 30mbps upload on a wired connection on the old modem, they are telling me to change the modem to the new one, but I am seeing so many problems listed. Should I do it, or just keep the old one and live with the slow speeds
@RogersDave My speeds have been acceptable and except for the odd ping spike to infinity and beyond like 2000 ms once and a blue moon it has been running well EXCEPT for two things.
I still find Xbox live to be laggy some times i suspect IPV6 will help this ALOT as it did before when i had it working. and there seems to be some bad UDP packet loss. I cant use my VPN to work on UDP it drops all day long like constantly. but i can use it ifi switch the proto to TCP. this was never an issue before. Sure some udp packet loss cna happen as UDP packets are never verified to reach their destination however constant drop reconnect drop reconnect forever. Shouldnt happen.
I've had to swap a few of these modems and I can confirm all of them were impacted by the UDP issue aswell. I really hope that this issue is put on high priority so it can be fixed ASAP.
