Buried the lede by calling this a "usb wifi adapter" and not "magic Ethernet adapter that you don't have to plug a cable into". This will come in handy for my systems that are normally air gapped or currently connected to something else, but sometimes I need to get another network connection on there for a few minutes. I don't always have a USB ethernet adapter on hand or enough cable, but I almost always have a Pico around.

Also I posted this comment using one. Speedtest says about 4 Mbps. Surprisingly usable for web browsing though. Very nice tool! I'll be keeping the .uf2 file around for sure.
