What’s going on with this BQM?

[Jon22]

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.

Hi Robert,

Yes, the BQM is back to how it normally was. The Hub 5 is still showing an increase in Pre and PostRS errors. Not sure if that is an issue or not?

Far too many uncorrected errors. There's a lot of noise on your feed. 

[Jon22]

Not sure if it might be related, as it’s not the cabinet that the coax goes to, but the cabinet just across the next junction up, has been making a rapid clicking noise for weeks now. Kind of like a relay clicking. I did report this on the cabinet issue/damage thread on here but nothing has been done about it.

I think the last time I had pre and post rs errors, was just before an amp in the cabinet stopped working. But that was quite a while ago. Anyway, I guess that’s for the network engineers to sort out.

The noise will be from a fan.
