Tony's router is starting to get flakey. Leo says that we've become used to using cheap routers. However, the cheaper the router, the faster it will wear out. If Tony buys a better quality router, it'll be more consistent and last longer. Netgear makes good routers.
The problem could also be Tony's modem. He'll want a DOCSIS III modem. For that, Leo likes the Arris Surfboard SB6141 which is $70 on Amazon.
