Re: Hub 3 / Compal CH7465-LG (TG2492LG) and CGNV4 Latency Cause

Rubber banding is worse than usual today, still no update or even information about the update from VM

I'm in area 30, 200Mb, router mode, fruitlessly retrying a pinhole reset every few days

Re: Hub 3 / Compal CH7465-LG (TG2492LG) and CGNV4 Latency Cause

I'm in area 30 on 200MB and last night I got the firmware update, I will test it today and see how it goes.

Re: Hub 3 / Compal CH7465-LG (TG2492LG) and CGNV4 Latency Cause

After waiting what seems like forever, my Virgin Media connection now looks pretty much perfect! The modem updated last night at around 03:30. My graphs are no longer littered with points showing up to 200ms in latency.

My new firmware is 9.1.116.608

Tests as follows...

 

IP SLA / Grafana UDP Tests

I have some tests set up from my home router using something called IP SLA, some of which use UDP traffic for tests. Proving that this update isn't just "only fixing ICMP traffic".

It generates test UDP telephony traffic, and sends it off to a server on the internet, which sends timestamped return traffic, and then records the delay for the jitter and latency in each direction. It sends and receives 10 UDP packets mimicking the g729a telephony traffic codec for each test.

Ignore the "One Way Latency" test. Due to the hot weather we're having and my router being in the loft, I'm getting a lot of clock drift as the large swings in temperature affect the clock frequency.

You can see that the UDP round trip time is now very low.

The downstream jitter is now extremely low, with upstream as expected on a cable service.

The MOS test for scoring telephone quality now also looks perfect with the exception of a single blip at 06:30.

ICMP - Ping Plotter, pinging around 50x per second

Ping plotter no longer shows huge spikes every 200ms.

CAtoUGT

 

Think Broadband

This still looks poor compared to the tests above. This is because my router prioritises traffic passing through it over responding to ICMP traffic. It's not a great indication of how the line is performing. Also, ignore the red blob from yesterday, I caused that.

I'd say well done Virgin Media / Arris but its mental how long this has taken. Virgin Media have handled the fault very poorly.

Area 31 still not had the update yet. 

Like the update that you've added regarding UDP latency, definitely more than a cosmetic update.

How did you get the update, automatically or by requesting it?

Automatically. From my experience with the "technical" support team there's little chance you would be able to request it.

I'm 31 and no update yet but I checked my superhub 3 network logs and one of them was this "SW Upgrade Failed Before Download - Server not Present" 🤔
