content: The short range is a feature in urban environments, the wifi protocol only runs on about 14 channels or less. This means with 2.4GHz your router is throttling itself so your neighbor across the street can live stream his smart oven and his kids watch movies in 4K and vr porn videos. It's also not only the router which might have to wait, but the client device as well if you're across the house and receiving your other neighbors wifi better. This is the inverse in rural areas, where indeed you might not have a neighbor for a half mile down the road. However, having many wifi devices will still cause the router to take turns broadcasting to all of them, and you could've avoided all of this with an ethernet cable. So if you see more than 50 2.4GHz networks, you're doing it wrong.
