My use case is very standard, netflix, youtube, voip video calls. Not running anything like a home server or dealing with transferring large files regularly. 4 family members but 2 are young kids.
I was thinking 300, but would I notice the difference from 150?
Thanks in advance?
It depends how many different streams will have running. 40 mbps is probably needed per screen or even more but 40 is absolute min for 4k. If you want to have enough room for people to stream and room for anything else they want to do you need 300 mbps minimum.
