Hi,

As per the title, for the last few days speeds drops to sometimes as low as 50 meg down and 20 meg up; ping and jitter also jump up in crazy numbers from 8PM - 00:00. It goes back to normal at any other times. I'm on the 350 meg package and never experienced this during the last 2 years. Can someone from VM check my line and confirm if its over utilisation in my area or a fault nearby that needs fixing ?

Im wired to my asus ac68u and vm hub 3 is in modem mode

nothing obviously wrong with those stats as far as i can see - can you also post the Network Log from the same area of the hub please?

it's also worth setting up a BQM to graph the performance of the connection from the outside

I will also set up a BMQ and keep an eye on the connection in the evenings

A few timeouts in the log but they are spread out -over a couple of weeks.

share the link to your BQM and a maybe repost the stats from the router when it’s going slow..
