TIL: so, wifi has these regulatory domains right, where if you don't tell your radio what country it's in, it doesn't know where it's allowed to transmit and effectively locks out all channels above 2.4GHz.
So I went to see how my chipset was configured... And somehow, it knew that it was in Canada and configured itself appropriately, despite me not telling it and there not being any OS-level service that would have done funky geolocation things.
