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

Hello,

I have sent the traceroute. Is there any more advice you could give to help with the bufferbloat and latency?

Like me your traceroutes aren't completing. Also your vodafone gateway isn't responing, again just like mine. This seems to be a new developement, traceroute has always been valuable as a diagnostic tool. It's highly likely vodafone have disabled ICMP on their gateways in fear of their own security. Can anyone else get a reliable traceroute that shows the gateway?? @Cynric ?

You could try running again with the -4 option (to force IPv4) but I think that'll die too. You could also try logging into your router's webgui and finding your IPv4 gateway in the status pages.

I'm not on IPv6, but no problems on IPv4, so those gateways definately respond.

Tracing route to bbc.com [151.101.192.81]
over a maximum of 30 hops:

1 1 ms 1 ms <1 ms vodafone.broadband [192.168.1.1]

Trace complete.

Yours completes, whether IPv4 or IPv6 always fail. I'm still on the Leeds gateway, there may be local issues to myself and to the OP but I've seen nothing official - as yet.

Could you show us what your traceroute looks like on I.Pv6?

IPv4 gives all the same missing hops, but the connection is fine and working sweet.

Aah. From a windows machine:

Looks like my Ubuntu install is carped out!

Thanks for the traceroute, I'm not at all familiar with I.P.v6.

I am surprised that (unlike I.P.v4) the intermediate servers are not Vodafone's, but all seem to be Hydra Communications.

So does that mean Vodafone don't have their own I.P.v6 network do you think?

Edit: Sorry for taking the thread off topic.
