This is a screenshot of some local WiFi networks (17 in total - Somehow Direct TV is its own antenna with connectivity), courtesy of WiFi Overview 360 (No promo).
I didn't think to tap the 5 GHZ option below. Maybe there are people on Channels 1, 6, and 11 down there. The squares can't mean that those are WiFi networks - There are more than 17.
We're not using what this app decides is the "best" channel for us.
Very good connection. I should try this with the AT&T router I used in Routerworld and see what we get. Definitely not actual internet connectivity.
Honestly I'm not very sure what this is. Any guesses?
