Garth is having trouble on his browser accessing the internet. It's very slow. Leo says that if he's tried different browsers and different websites, then it sounds like the DNS configuration with his router is screwed up. He can use a third party DNS like OpenDNS, which is free and easy to set up.
Jennifer wants to be able to control all her kids' devices at the router level so they can't work around it or stay up all night. She's also concerned the Verizon FiOS router could stop working. Leo says it may be a good idea to get an additional router for wireless applications and turn off wireless capability in the Verizon router, and just keep it wired. She should use the Apple Airport Extreme. Then she can work with the settings in the Airport under the Access Control List.
Don wants to be able to cut off access to the internet with a touch of a button. Leo says that some routers allow him to do this by MAC address (called an "access control list"). They can set the internet to go off at certain times. He can also go to OpenDNS.com and use their DNS system to filter out unwanted websites. This will work for smartphones as well.
