Hey @AndyPandy,
Hope you are well

No I haven't yet, but I will set it up now. I decided to switch the playstation on after a while and just like clockwork, as soon as it hit midnight - huge latency spikes, continuous packet losses and completely unplayable gaming online. I don't have any monitoring tools but I have recorded my game play to show the network metrics that can be toggled on from the menu to be viewed during gameplay.
Please note I have tested gameplay with both a wifi router (the one hey broadband supplier) as well as a direct ethernet cable - both yielding the same results. Midnight hits and it's horrible!
I'll set up the monitoring tools now and will report back soon
Thanks for the help btw - super appreciate it
