I’ve had a stable 200mb broadband for several years - last month I upgraded to 350mb but since then my connection is dropping off all the time all my devices are going offline all day and the internet grounding to a snails pace at times which never happened before!
i have spoken to VM on phone who got me to reboot router but made no real difference!
i can worrying see lots of Errors and Critical messages in the network logs!
Thanks for posting back here with the additional information.
Would you be able to complete a speed test whilst the Hub is in modem mode please so we can make sure that the correct speeds are being reached to the router? You won't have to use modem mode for long, it will only be used for testing the speeds. Only one port will work for Ethernet connection as the wireless will be disabled.
Unfortunately I'm unable to do this as my only computer is a Mac book Pro which has no built in Ethernet that I can use without an adapter and I don't have one!.
I use a Pro and an Air too - I got thunderbolt-ethernet and USB3-ethernet adapters from eBay (<£10) for just this very reason. Also useful when the wifi is poor. So with 20m of Cat5e cable also on eBay at £3.95 I can get temporary connection where the wifi doesn't reach - e.g. in garage whilst following youtube videos on how to fix car problems, or garden shed when unwanted visitors arrive

Well tonight everything’s gone off - the Internet is completely unusable! I’ve had to resort to posting this message using my phone 4G connection. Trying to run a speed test on my WiFi was almost impossible - says I’m getting a 0.09mb connection, Just what you want when your paying for 350mb, feel like I’ve gone back to 1982 dial up
