How can I extend my WiFi connection?

Episode 954 (2:27:37)

Alan from West Los Angeles, CA
Airport Express

Alan needs to get a WiFi repeater to extend his WiFi range in his house. Some say they work, some don't. Leo says that a repeater will work best if he gets it from the same company that makes his router. Matching chip sets and firmware is best. Leo prefers the Airport Extreme and Express from Apple. Another option is Powerline networking.
