DriverGeniusUSB 2.0 Extender to RJ45 Over Cat5e/ cat6 Connection up to 50 Meters, Driver-Free Version Ethernet Extension Adapter (NT50-A)

Can this go through a router or switch and still be usable?

Is there any latency with this? I want to use this for gaming.

Am i able to have a network signal coming the other way around, like a network adapter receiving a signal and transmitting it through usb to ethernet?

Does it work with mac ios 10.15.6, and if so- any software to download?
