What's the best internet alternative to Frontier?

Don from Rancho Cucamonga, CA

Episode 1288

Don is a Verizon customer and they just got bought by Frontier communications and now his FIOS internet speed has been cut in half, which is worse than dial up. What can he do? Leo says that Time Warner cable is probably his best bet for broadband. They just got bought by Charter Communications, though. Cable is usually better than DSL, but it also depends on how it is in his area. As for phone service, he can just keep it or simply cancel it. He should make sure he gets a DOCSIS III modem if he goes with cable, though.

Can I split off my internet and phone modem?

Episode 1114

Jim from Woodland Hills, CA
Modem

Jim wants to buy his own modem and send back his Time Warner modem. But they say he has to keep it because of his telephone service. Leo says that may be true, since cable phone service uses VoiceOver IP and the cable modem box may require it. So if he is going to use his own modem for internet, then he'll need a splitter to divide the internet traffic. And that's why Leo hates cable monopolies. His only choice is his cable company. He'll get about 1-2 Mbps with Netflix at best. And that likely means a downgraded quality of Netflix.

Should I buy or rent my cable modem?

LaxMan from Tempe, AZ
Motorola Surfboard modem

Laxman has to get his own DSL modem for his cable internet service, but will they be backwards compatible? Leo says that DOCSIS III modems have auto configuration menus that can handle older devices. But buying is a far better option than renting that modem for $5-7 a month.

Leo likes the Motorola Surfboard. He will have to tell his ISP that he bought one and make sure they support the model he wants to use.

He might be able to disable the router portion of his modem/router, and buy a replacement for the router. Then he could change the DNS settings. The chatroom says he could set up a "DMZ" to his own router.
