Setting up Ethernet

I have heard from most computer professionals that ethernet is much better than using wifi for home computers because of the speed compared to wifi speeds. Today, I installed an Ethernet switch underneath my desk. First, I ordered an Ethernet switch from amazon (Amazon Link), and then I also ordered a 15 foot long cat7 Ethernet cable (Amazon Link). Once they arrived, a few days later, I plugged an ethernet cable into the nearby ethernet outlet, then sent an internet signal to another port that I plugged into the port that I labeled “North Room” (which was my bedroom). Then I plugged my Ethernet cable I just ordered into there and then plugged the other end into the switch, which I mounted right below my desk. So far, it seems to work better than Wi-Fi. I wanted available Ethernet ports because I have several Raspberry Pi’s that I use for different projects that need to be connected directly using ethernet instead of wifi is because I had issues with my Raspberry Pi. Either the wifi chip inside the Raspberry Pi isn’t strong enough, or it doesn’t have wifi compatibility built-in.
