All of you reported experiencing speed degradation over time (somewhere between 30 minutes to 12 hours). One question asked by Hitron is if this degradation occurs only using a Wired connection or if it occurs on both WiFi and Wired?

 

Also, did any of you run firmware version 2.0.10.13 or 2.0.10.14 for a couple of days without experiencing this issue (was it introduced by 2.0.10.19)?

 

Thanks

I thought I'd replied earlier today, but maybe I hit Cancel instead of Post.

 

Rogers & Hitron technicians stopped by this morning to investigate how in about 10 to 24 hours, roughly once a day, my bandwidth on a wired connection will drop from 940-960mbps to under 10, sometimes 0.2-0.8mbps. It immediately resolves itself on a reboot.

 

I left a PC running plugged in to the router with TeamViewer on it, so when it next happens, a Hitron technician can run a series of troubleshooting commands to explore what might be wrong.

 

Strangely, I'm now looking forward to the next time service degrades that much, since I'll be able to help fix it. 🙂

I thought I'd replied earlier today, but maybe I hit Cancel instead of Post. (Edit: I didn't, as I wasn't able to post this, twice now! Here's hoping a third time is the charm...)

But as it happens, it last occurred at 10pm the night before, and I'd rebooted the modem then, so it wasn't occuring while they were here. I have a PC running that's plugged in to the router with TeamViewer on it, so when it next happens, a Hitron technician can remotely run a series of troubleshooting commands to explore what might be wrong.

Hi Louis,

 

Mine does the same thing, but every 6 hours - pretty much like clockwork 🙂 ... so I'm going to be looking forward to hearing what you find out ...

 

Good luck!

@RogersDave

 

Hardware Version 1A
Software Version 2.0.10.19

 

100u plan without bandwidth limiter:

100u plan with bandwidth limited to 85mbps down and 9 mbps upload via ASUS RT-N66U:

Before i was getting lots of fluctuations from Grade F during congested periods and Grade D during the day. Now i am experiencing A's by setting my bandwidth cap between 80-90% via QOS.

Re: CODA-4582 - Open Issues for Investigation

@RogersDaveYep, I am getting 'C" grade in bufferbloat as per your instruction. My best so far. Download was below 80ms and upload was above 1000ms. Not the best but better than before.

 

Now in a simple layman term, what needs to be done here? I don't know if the speedboost is good or bad.

Re: CODA-4582 - Open Issues for Investigation

nothing needs to be done, it's just the way the test calculates buffer bloat. Speedboost is a GOOD thing.

I don't think your connection is bad, the problem with torrents is depending on seeds/peers its not consistant. I think if speedtest.net shows you as getting good speeds then that is your real speed.


The other thing with torrents is that, depending on your settings, they can be VERY hard on your NAT device.

 

If you are doing a speedtest, that's one TCP session that needs to be NATted.

 

If you are doing torrenting with, say, 200 connections, that's 200 connections (plus there are always some disconnections and some new ones) that the NAT device needs to keep track of.

 

So a NAT router that can easily handle one connection at 800 megabits/sec could easily only have the processor capacity to do 300 megabits/sec of heavy torrenting. If you are using a router that lets you observe its processor activity, that would be an interesting angle to explore...

Re: CODA-4582 - Open Issues for Investigation

@RogersDave I have been noticing very bad speeds for over the past hour and have never seen speeds like this? It must be the rogers network in North Oshawa near 5 points mall? Smiley Surprised And I did another reboot of the Modem and the same results. 250/20

Re: CODA-4582 - Open Issues for Investigation

Received the .20 firmware this morning before heading to work.  Did a couple speed tests and everything seemed like it was fine.  Tried 4 or 5 servers and was getting around 890/20 which is a lot better than I was getting before around 300/2.  Came home from work and ran a couple more tests, and the speed is terrible again.

Both were taken at 12:40am.    Currently running in bridge mode, connected to an Asus RT-N66U.

Re: CODA-4582 - Open Issues for Investigation

I must say that i do not remember the last time i had this 'slow' download speed.

I had issues with upload recently due to the issues on my node, but that was 'fixed'.

 

Since i got this .20 firmware, i can't say that i am very happy with down speed especially, upload is so so, far from advertised speed 'of course' (sadly), but download .. on Gigabit, 150-250, the most i saw was 700mbit, but not for long.

I can't say .20 is the reason for this, i don't know, but, it started happening since i got it.
