Bufferbloat

[Willow123]

I seem to have high broadband bufferbloat on latency. I cannot see any QoS settings on the router and would like to know how to improve this. I have a few smart devices and also notice some lag while online gaming

You new image hasn't been moderated yet, but your original shows you probably haven't allowed the router to respond to pings..

You need to enable ICMP ping on the router's WAN. I can't remember what vodafone have called it but it needs enabling, as it's clear from your BQM that it isn't (you'll likely find it in the firewall settings). Or your ip is wrong, which I seriously doubt.

@Jayach no worries. IPv6 needs no real routing, so I'd expect not to see much mention of vodafone. Google for hydra - they have their fingers in lots of pies. The IPv6 infrastructure is probably leased.

@Willow123 there's nothing you can do about poor latency caused by vodafone's routing. I would have expected better pings from IPv6, but if your connection is travelling long distances before even reaching the spine high latency is inevitable. Even raising an issue with vodafone is unlikely to bring a resolution. Just keep your fingers crossed that it'll straighten itself out.

Did you find your gateway IP?

Hopefully things sort themselves out, if it is a routing issue. Currently reading 42ms on black ops 6 😅 Would a different router fix those issues? Also, what is the difference between IPV6 and IPV4? 

[Ripshod]

@Jayach, where I mentioned routing I meant to say NAT.

I'm wondering if there's more to learn by using iperf (https://iperf.fr/) as a lot of speed tests only give the summary figures. Any thoughts?

[Ripshod]

I have iperf3 on a remote server, leftover from the days of the original gateway issues. I don't know how much use it would be here as you need iperf installed on both ends of the connection, and running as a server on the remote end. 

[Cynric]

@Ripshod If I remember correctly there are public remote servers.

[Ripshod]

iperf tests performance (speed), not latency.

@Ripshod  Ooops. My bad. 😉
