How can I get better Wi-Fi reception?

Episode 1222 (25:42)

Phillip from Camarillo, CA

Phillip's girlfriend is having issues with her Wi-Fi. Leo says that it could be an interference issue with metal frames and dead zones in her home. Would a range extender work? Leo says that they can if she gets one from the same manufacturer as the original router. But if the main home is using a router from the carrier, then that could be a problem. It would be better to buy a new router with the extender and match them together. Another option could be powerline networking.
