What’s happening with this BQM?

Can someone help me figure out what’s going on with my BQM? Noticed since last Tuesday that some websites occasionally take a couple of clicks to load. They’d just hang and then click on the link again and it would load straight away. Thinking there might be some issue with the router, this led me to reinstalling the router software (once with Pfsense and again with Openwrt). The BQM has always been relatively flat, for a VM connection, since I joined last year. Since last night, I’ve had these blocks of yellow. They seem too flat and consistent to show congestion. Speeds are completely fine, near enough maxing out the line. I changed the WAN port to another one around 5:30pm ish. This seemed to drop the max latency for a bit, then it went back up. Ignore the red packet loss, that’s me doing things. I’ve done a reset using the button earlier on the hub.

Changed to router mode on the hub just before midnight. Disconnected the router and just left the connection idle with no devices connected for an hour. No change. I’m guessing it’s some issue between VM and Thinkbroadband. No idea what as if I run a traceroute, it looks normal.

A normal day for my connection:

potentially DNS issues, noticed you got no reverse DNS on your pathping output.

Thanks Chrysalis. Might be a dumb question but how would I fix that? Is that a problem my end or Virgins end?

Interestingly, the BQM does occasionally go back to normal for short periods.

The shapes you are seeing here are likely caused by power management in the modem or a device within VMs network. I call this 'short grass'.

The reason they go away sometimes is likely because there is some load that snaps it out of a low power mode.

Used WinMTR. Couple of traces. Am I right in thinking there might be an issue as soon as it hits ntt.net?

No, thats fine, the loss is only on a intermediate hop, router treating pings as low priority.

Thank you. I’m not sure what’s happening then to cause the latency blocks.
