Anthony is buying a newly built home and it comes with Cat5 Ethernet cable. He's wondering how the Wi-Fi performance will be. Leo says it depends on the design, but he may need to get a few access points and salt the house with them here and there. Leo recommends staying within the family of his main router.
Another good idea is to use the same name and password with every wireless access point. One other option is to use WDS as his firmware for the router, so he should make sure he has a WDS compatible router. Some people, Leo included, also use power line networking, which utilizes the electrical wiring as the internet network connection.
