As indicated in the original post, wired connections can continue to perform in less than optimal conditions. Wireless is plagued by problems. OP didn't really cover this, but there are problems like: Wireless performs more like a hub than a switch. Take a look at your router admin panel for a status page that includes your clients. People forget that they have a cell phone (or four), tablets, laptops, appleTv/smart TVs/chromecast/fire/Roku, webcam/baby monitor, smart fridge, smart light bulbs, etc etc etc etc. That's all competition. 802.11 happens in unlicensed spectrum. That means, in addition to the wifi devices above, all the other wireless devices you AND YOUR NEIGHBORS have all pollute the spectrum. Even non-wireless devices (the Microwave??) can pollute your connection. WiFi is junk. (Relative to a hardwired connection to a quality switch.) If your wired connection seems to perform worse, I'd say it isn't that your WiFi is better: I'd look for problems on your wired network.
