What’s wrong with just Wi-Fi?
"In smaller homes, a router-and-modem Wi-Fi rig can handle just so much. With a couple of laptops and a phone or three using the wireless bandwidth in a home that’s under, say, 2,000 square feet, everything will likely work fine. But add anything from a smart TV streaming a movie service to a wireless audio system to a connected fridge, and the bandwidth that particular Wi-Fi device provides can become rapidly unstable. And no one wants to see a frozen screen or “the spinning beach ball of doom” on a device in the middle of a critical Zoom meeting or the kids’ e-learning session."
