Re: 5th Upstream
On the new firmware now, modem was stuck in flashing yellow light loop for some hours, I figured it had enough time to upgrade firmware so power cycled it, it went back to flashing yellow and resigned myself to reporting a fault later, but then when I noticed my IP come up in pfSense, and glanced back was green light.
Speedtest is ok, but all my 3.0 upstream channels are stuck on QAM 16.

What's your downstream say, I have over 3.8 million uncorrectable errors on my 3.1 but not messed to reset it yet as connection appears fine?

That’s absolutely normal nothing wrong don’t worry uncorrectable errors on the 3.1 channel

My upstream is QAM64 now, it fixed itself.
I will attach a screenshot of my downstream here, but so far so good, no timeouts, and 0 unfixable errors.

Re: 5th Upstream
This firmware has messed up my 5ghz WiFi channel on the hub, after I rebooted it to clear the errors I had no access to my 5ghz WiFi, turns out it had locked itself on channel 120 which is a DFS channel for radar! So changed it to 40 and all is fine again.

Re: 5th Upstream
In basic terms, what are the advantages of these new 3.1 channels?

Lots more bandwidth available to customers, the channels were here before, just that the hub5 wasnt reporting them in the GUI.

Re: 5th Upstream
Tucked into the 5th channel and the Docsis 3.1 scenario are some technical surprises. Given that the D3.1 and D3.0 upstream data needs to arrive at the same time sort of thing, the D3.0 channels are woven into sub-channels of the D3.1 channel. Quite a clever innovation by CableLabs.

I've reset it since posting, it currently shows corrected errors 2896038797 and uncorrectable errors 417317.

Re: 5th Upstream
Luckily I am still zero, I sympathise as that would probably annoy me if it was going up.
You can try reporting, but I think if you dont have a visible effect on your service, they will likely say is no issue with your service.

It's not normal. What I'm not sure about is whether the 417K uncorrectables you have are entirely down to your data. Your modem "sees" everything on your segment. The modem filters on a unique security key and that data proceeds past that gate and onto your router.
Therefore, the uncorrectables would statistically include traffic not destined for you. That said, I have just 57 uncorrectables and it's not rising. I would deduce that yours is a somewhat noisy downstream.

My downstream is saying locked SC-QAM is something wrong there?

That'll refer to the primary channel which is currently a Docsis 3.0 channel. When the modem is turned on it goes through registration - that's on a D3.0 channel. I expect the D3.1 downstream channel to say QAM4096 (as mine does).

On the Downstream tab it does say QAM 4096 and upstream says QAM256, so all ok on that front?
