M350 Slow and unreliable

Hi Guys, just had VM installed a couple of weeks ago from BT as i wanted faster and more reliable speeds... all good day 1 but downhill after that, i am constantly having to reboot my Hub 3 as a few hours after it resets i get 20 - 30mbps at best (over 300 at startup)

Everything in the house is as it was with BT and worked fine, i have a PC using a powerline which i use as work calls and teams etc, worked okay with BT and now very sketchy voice calls etc

I waited the required hour for service and they said an engineer would be booked but having spoken to 2 neighbor's who installed the same on the referral system they are getting the same problems!!

I inclined to think its not my network but the Hub to external?

Any ideas would be gratefully appreciated

Re: M350 Slow and unreliable

Hi Alessandro, thanks for the reply, yes seems better but i had just rebooted the router

In Modem mode Ping 9ms Download 313.08mb Upload 24.00mb

In Router Mode Ping 11ms Download 191.00mb Upload 18.00mb

Although from the same vm speedtest site from my phone

Ping 11ms Download 17.87mb Upload 14.16mb

Then a couple of hours later all slowed down and not able to use teams at all

Create a BQM and post the live link.

Access your HUB on http://192.168.0.1, log in, and copy/paste the 'Upstream', 'Downstream', and 'Network Log' tab data, as text (You may have to click post twice due to an error), across multiple posts as requried.

Re: M350 Slow and unreliable

Your HUB stats don't look to bad too be honest (Downstream power levels a touch high, but in spec).

Can you create the BQM when you get chance.
