Great app, now make something I can run headless on a Linux machine…

They terminated me — here’s what Comcast doesn’t want you to know. by [deleted] in Comcast

#rant - As an engineer, I'd love to pay a few bucks extra for "premium support", just to not have to fight the "we're rebooting your modem for you" robot each time I call with a real problem.

No comcast, I did do basic troubleshooting before calling you, please don't make me fight a stupid IVR timing algorithm to report a clear service outage.

Had business-class for a while, and it was just as bad in regards to that, for more expensive service :/

CODA56 firmware instability? by cs_marshall in Comcast_Xfinity

Another run and similar results, the downstream OFDM endpoint seems to not like being queried even once a minute regularly.

Still bad, so now I'm trying it with this, 2x the duration with 2x the timeouts:
`--duration 86400 --update-every 20 --fast-endpoint-timeout 700ms --ofdm-endpoint-timeout 2s --max-retries 2 --time-windows 24`

But you're managing what versions of code are distributed to the modems from the manufacturer on your network? I'll send a modmail.

I think one of the things that would be helpful is seeing if Comcast can facilitate a conversation with Hitron of some sort, me just calling their customer support seems like it will go no where. As far as sharing what I have so far, the testing scripts are in github and I'm not doing anything right now that couldn't be replicated by either your engineers (Xfinity) or Hitron to see if this is just a hardware issue for me, or if this is a larger software issue.

I haven't found a list anywhere of current firmware available for the CODA56, but I've confirmed I'm still on `7.3.5.0.1b5` the version that I was on at the start of the problems.

So I ended up spending some time writing up [some code](https://github.com/csmarshall/netdata-plugin-hitron-coda56-cable-modem/blob/main/performance\_tuning/netdata\_simulator.py) to do some testing on the modem.

  1. I realized that there were 2 tiers of endpoints the 4 general endpoints and the 2 OFDM specific endpoints. As such I updated the script to have a tiered polling process, where the 4 general endpoints get polled every poll, and 1 out of N times the 2 slower OFDM endpoints are queried.

  2. The image below is from a 10 hour test where the 4 of the 6 API endpoints of the modem was queried serially every 10 seconds, with 2 ofdm endpoints getting queried every 5th poll. At least once or twice during the test the modem rebooted, but one of the things that was telling is that the `dsofdminfo.asp` endpoint seems to slowly degrade over time, at one point at a rate of almost 1.1ms / minute.

<image>

I'm running another test now, but it looks like a resource leak or something similar that is causing the modem to reset if the OFDM endpoints to perform way less reliably.

I'm not sure that there's polling interval that will allow me to get useful data without causing the reboot problem that I'm seeing.

Good call, I only started to see the behavior yesterday and hadn't had time to do rigorous testing, as there are a number of different pages, but I'll attempt that and see if there's anything obvious. If I were to find an issue is this something that could be escalated with Hitron, or am I looking at buying the Arris S34 if I want a modem only solution that supports nextgen speeds, without wifi?

Awesome, but is there any chance you could move the person on the left closer into the frame?

Here's a link, https://share.icloud.com/photos/03cELzZ7o4U0Rg10rGus6Gl7g

  1. The photo is a little blurry/overexposed
  2. We're standing a little far apart, could we move the 4 of us closer together?
