low speed in the evening (area 06 Strood)

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

Re: low speed in the evening (area 06 Strood)

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

Re: low speed in the evening (area 06 Strood)

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..
