The conversation around Wi-Fi and Ethernet in the home usually boils down to a single piece of advice: when you can use an Ethernet cable, you should. Most people don't have fast enough internet to encounter the true bottlenecks of wireless networking. However, Wi-Fi networks struggle with range, interference, and bandwidth, and Ethernet cables generally avoid these limitations. Smart home gadgets can be particularly grueling for a wireless network. A fully loaded smart home could include a number of connected devices in the triple digits, and they could be strangling your Wi-Fi bandwidth.
