I’ve seen a lot of other people have had similar issues on the forum and I’m experiencing the same latency spikes and lag which makes gaming unplayable most of the time.
https://www.thinkbroadband.com/broadband/monitoring/quality/share/8653454bed9800f1f15e05821c023c7170492eaa
I have the 600mb package and no issues with the speed but throughout the day I experience terrible lag spikes. This has been going on for months now and it’s unbearably bad at this point.
Is anyone able to confirm my issue after taking a look at the BQM graphs? Any suggestions of things to try to improve the latency. I play on wired connection on a PS5. Would a 3rd party router and using the VM hub on modem mode help with latency?
on 28-03-2022 15:20
Initial thoughts from the BQM are that it might be over-utilisation (network congestion), but there can be other causes. The other causes can usually be resolved, over-utilisation much less likely to be fixed (or indeed admitted to by VM).
There are benefits to running in modem mode with your own mesh or router, and I do that, but I can assure you that it doesn't improve latency so won't help your specific problem.
Connect to the hub by clicking on this link http://192.168.0.1/ That should pull up the log in page for the hub. But don't log in, just click on the link "Check router status" That'll bring up a window with five tabs. Open the Downstream tab. Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here as TEXT not screenshots. Post that, do the same for the Upstream and Network log. You'll get an error message when you post the Network log, just click on "post" a second time. Then we can check for any obvious problems with power, noise or error counts.

Thanks for the reply Andrew, appreciate the quick response.
A shame that an additional router won't have a significant effect on the latency 😞

Any idea when the hub was last rebooted? Power levels and SNR look good, but the number of T3 timeouts and post-RS errors are very high (restarting the hub clears the error counts).
BQM shows an obvious problem, without explaining what it is - the shape and timing look wrong for over-utilisation (network congestion), but don't give any clues to what else is happening that's causing those latency problems, nor whether the problem is unique to your connection or affects neighbours. Is there anything networky going on in your property that you can think of that started around 9pm last night, and stopped at about 2:50am this morning?
on 29-03-2022 12:54
The hub isn’t rebooted frequently at all, only if the internet stops working completely which is rare so I’d say it’s been a good few months. Will give it a restart today but I’m certain this won’t resolve the latency issues as they have been going on for close to a year now.
Nothing in particular went on between 9-2am as far as I’m aware apart from the usual stuff like family members watching TV, playing PS5, etc. We also have a ring device, mesh network and 2 switches in the network - if any of these could be affecting the latency? But again these are usually on 24/7 and not in particular for those hours mentioned.
on 29-03-2022 15:09
Nothing you are using would affect latency on it's own. If something were faulty it would effect everything and not just latency.
Your BQM is horrible by the way and something is amiss on the VM circuit. As Andrew-G has pointed out a new Router would be a waste of money at this time. Until this circuit is fixed don't bother.
Post the latest stats after you have done a pin hole reset.

Thanks Adduxi.
I've done a pin hole reset (didn't reboot the Hub yet - let me know if that matters).
Thanks for the advice on the router. Regarding the VM circuit being messed up - do you know if this is something VM are able/willing to fix?

The pin hole reset should reboot the Hub as part of the process. Your stats are all okay at the moment, but check the PostRS errors after 24 hours and the same with the BQM.
