Yes, wired is always better, but it’s not always feasible. Not everyone can choose where to place their router — renters may not be able to get permission to have new holes for coax cable or fiber equipment, for example. Many homeowners would prefer their network gear live out of sight, as well, and may not be interested in the expense and headache of running ethernet throughout their homes. Additionally, particularly with the advent of Wi-Fi 6, going wired can be past a point of diminishing returns in a lot of homes with a good router or mesh system, as latency and throughput gains fall short of noticeable for all but the most competitive and dedicated gamers.
