Review on Bionik Giganet Adapter USB 3.0 to Wired Ethernet: Nintendo Switch-Compatible, Ultra-Compact Dock-Size, Gigabit 10/100/1000 LAN Port, Enhanced Airflow Grill Pattern by Greg Bellman

Wanted to get an ethernet option for my switch and it worked with no problems. I had to unplug and plug it back in a few times before the Switch recognized it and proceeded with the wired setup, but everything else was smooth after that minor hiccup. When you unplug the Switch, it switches to Wi-Fi, but once you put it back on the dock, it doesn't automatically switch back to Ethernet.
