A:Answer No. It is not.
You do not want a hub on any network that you run. The GSS108E is a managed switch.
It only has eight ports. But I am finding it a good seitch for my home network.
Most home networks do just fine with an unmanaged switch.
The only thing a hub is useful for is sniffing packets while troubleshooting on your own network.
With a hub, only one device can use rhe network at a time.
With a switch, multiple decices can communicate at the same time.
With a managed switch, you can further segment your networks into other subnets.
