My brother has a problem with his house. Essentially with the size of the house and number of walls he has not found a WiFi station that can provide service over the entire house (and large backyard) reliably. I think that 2 WiFi stations would probably work best, one on each side of the house. But, I do not have any experience with this. What is the best way to extend WiFi like this. Essentially he wants just one WiFi ssid that he can go anywhere and it switches base stations as needed.
