Why won't my router allow me to visit a certain site?

Episode 953

Perry from Southern California
Linksys router

Perry can't navigate to a specific website. He keeps getting a message that says "this page can't be displayed." If he bypasses his router, he can get to the sites.

Will I benefit from upgrading to a DOCSIS III modem?

Jack from West Orange, NJ

Episode 952

Jack is being offered a newer, faster modem (DOCSIS III). His cable company has told him that if he takes them up on it, they will have to disconnect his second modem. Leo says it's OK. It may be the speed difference which causes them to disconnect it. He could get a second DOCSIS III modem and try that, though. He can always reconnect the second modem after they leave, too, and see if it works. A wireless repeater may be a better option to get internet through his house, though.

Will the UN Take Control of the Internet?

Russia has been in favor of a UN takeover of the Internet. The International Telecommunications Union (ITU) actually does regulate the Internet as they have all communications mediums since the late 1800s, but the Internet is largely modeled and operated by the United States.

Why am I not getting anything back when I 'ping' certain domains?

Adam from Hesperia, CA

Episode 922

'Pinging' is a method of directly contacting a site just to confirm there's a connection there. According to the chatroom, if he has too many devices on his FiOS router, it could be preventing the router from connecting temporarily. Each device takes up an entry on the NAT table (Network Address Translation). Size limitations on that NAT table could cause the router to choke.
