2000ms+ lag spikes every 6 minutes

Question

Hey, I'm having a frustrating issue where we get a huge lag spike every 6 minutes. Tried to have a chat with the Virgin Media help phoneline, who sent me a new router. Tried that with nothing else connected but experienced the same issue so I'm fairly certain it's outside our network. Have had the quality monitor running for a while, but because the spike is so short it does not catch it often. Here is a day when it catches one spike -

But this happens EVERY 6ish minutes. If I run a constant ping test we see -

Which makes playing games impossible and video calls irritating! Any Help appreciated!

You have more of a problem then a lag spike you should not see low level packet loss like that VM may need to reboot something or you can reboot the hub or equipment that for BQM pinging to.&nbsp;

Cardiffman282 · Answer

There's constant packet loss in the BQM. Check for local faults on 0800 561 0061 / 150.

MattG3 · Answer

Cheers, I didn't realise that was out of the ordinary to be honest. Would make sense though, if I ping any external IP I see packet loss when this dropout happens. I've rebooted everything in the LAN a few times and switched out the hub for a new one. Bqm is pinging the hub so I think it may be Virgins kit

MattG3 · Answer

No faults registered unfortunately on virg.in/servicechecker, will check via the phone line too though
