Help: Assess my BQM?

Hi all,

Was hoping someone more experienced might be able to offer some insight into my BQM:

I am on Virgin Media Volt M500 which runs into a Superhub 3 in modem mode, with routing and Wi-Fi provided by an Eero 5 mesh system.

To contextualise the obvious changes - from 8am I shut off my linux ISO hosting box to see what the line looked like without it, and I turned it back on again at 12.30pm - so that explains why the blue increases I guess.

I suppose my specific questions are:

- I've read the page on interpreting these results a few times now, but I still feel like I need an ELI5 - what does a broader band of blue ("average latency") actually mean? Does that mean over a certain period the average latency result per min/similar has varied more?

- The yellow (maximum latency) - between 8 and 12.30 on that graph really all that was going on other than passive connections for various household gadgets was me using my work laptop, and nothing very challenging - no zoom calls this morning! - in other words, the yellow between that time period is close to what the "resting state" of my connection is, and I would say that's a pretty typical amount of yellow compared over many weeks of running BQM. Is that a cause for concern? The Guide to interpreting the BQM's example of a healthy connection is practically all green with only a few hints of yellow blips here and there.

If there's anything in here that folk would consider cause for concern, what would you recommend to troubleshoot / fix? I had a Virgin engineer out the other week and he did a few things - tightened connections, changed out some old looking wiring at the local box etc.

Thanks all!

One thing I can tell you is your minimum latency is kinda high.

I am on a faster connection but id expect out latency to be the same.

Here is my graph for compaison

Yeah other than the latency being high (if in england) - my virgin BQM from N.Ireland was similar

Thanks! I had meant to ask whether it was line with what I could reasonably expect. Interesting - any idea as to why that might be?

My Broadband Ping

The blue line occasionally getting thicker coinciding with the min latency slightly dropping I think is related to docsis power saving state. I ignore it.

Is this a RFoG connection? They seem to have a higher ping?

You can ignore it for sure. It's when the ping to respond to the BQM can go into a minislot that's already been requested so no need to go through the request-grant-transmit cycle to reply to TBB, straight to transmit as there's capacity left in an existing grant.

Depends where you are in the country to what ping you get. I'm in Yorkshire and mine is closer to the OP's figure than to yours. I also get around 20ms for at least half the day and c.15ms for the rest.

Sorry, only just seen this - thank you! That's good to know.

Thanks for explaining - that's good to know!
