Matthew wants to know if he can bridge two Airport Extremes, put them 300 feet apart and still get a signal. Leo says it's no problem, except for the distance. 300 feet is a long way for 802.11,b,a,c, which max at about 150. 802.11AC, though, can go about 300 feet. One thing he can do is use a directional antenna from one to another. A new Airport Extreme, though, will work. Leo advises sticking with the same company's products to make the extension.

Jay is thinking of getting a new Apple Airport Extreme, but he also wants to use the DDWRT firmware. He's heard that it's more secure, and the Asus router he's looking at comes with it.
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.
