Similar to other messages in here, I have had the Volt upgrade TV and broadband package. I pay for 1gb internet and through a ps5 wired connection i will get about 800-900mb download speed but often only 8-12mb upload speed.
The lag on my gaming is really really bad.
I was previously on a 75mg internet package and myself and my son could be gaming in seperate rooms, whilst we also had various ipads/smart tvs connected over wifi and there was never an issue.
Currently its not only effecting gaming, me and my wife work from home 3 days per week and microsoft teams calls are regularly struggling or disconnectin altogether. So speed says its auick but connection stability/ping just isnt good enough. ive seen numerous posts with similar issues
