I have a superhub 3 and was on the 200-250mb package.
I have a load of smart devices, we both work from home and our daughter is doing school work from home.
In total have around 30 devices connected to WiFi.
Used to get nest cameras dropping off the network and zoom/Skype calls very hit and miss.
I bought a Asus mesh system.. superhub now in modem only modem. And everything is spot on.
