VM engineer came this afternoon, speed was alright he changed the white internal box and some connectors from the cable ends, all was ok until 6.30pm when the speed (dropped wired and wifi), latency and ping went high, theres definitely a network problem, the connection during the day isnt as stable as it used to be its up and down more than a yo yo, new logs and BQM below

That doesn't look right at all - just to confirm it's been the same way since the engineer left?

Cheers.

nuttyslack · ‎22-03-2021

It's still the same with the speeds from 6.30pm onwards, very unstable and Saturday it went altogether but came back after a reboot. Maybe it's over utilisation on the network, maybe when everything is some kind of normal it will settle.

I tried showing the engineer the bqm but he wasn't interested.

Ryan_N · ‎22-03-2021

Unsure why they wasn't interested as it would only help them - apologies for that.

From 6:30PM when does it last until? Can you let me know how it goes tonight and can you screen shot the time periods please.

Cheers.

nuttyslack · ‎23-03-2021

thanks for the reply, didnt get chance to test it last night, will try tonight, it can last until at least midnight come the morning its back to full speed, until roughly the same time again, normally its around 8-830pm it starts.

Zak_M · ‎23-03-2021

Do keep us updated @nuttyslack.

Kind regards,

Zak_M

nuttyslack · ‎23-03-2021

Did a speedtest on your webpage, less than a 3rd of the speed it should be.

nuttyslack · ‎23-03-2021

about 1hr 15 mins later slightly worse speed
