How can I extend the Wi-Fi signal from an Apple Airport Extreme?

Episode 1106 (2:23:09)

Jeff from Los Angeles, CA
Apple Airport Express

Jeff has a 3000' square foot house and has several Apple Airport Expresses to relay the signal from his Airport Extreme. Leo says that Jeff should have the Express in 'Bridging mode' and should let the Airport Extreme choose the channel because it will adjust according to congestion. Just select the option to extend the network and let it handle everything else.
