Leo has been trying a new DNS service called NextDNS. Not only does it keep your online activity private from even your ISP, but it also blocks ads and has great parental controls. And it's free for most types of online activity.
Brian has an Apple Airport and every time he gets on the network with his phone, the internet drops out. Leo says to check his DNS to see if it's properly configured. That can be found in network settings. He should also try rebooting his router. Steve Gibson has a tool called DNS Benchmark at GRC.com which can tell him how well his DNS settings are responding.
Dan got a new router from his ISP and he can't change the router settings. They're grayed out. Rich says while he can change the router settings in the router, he can also change them in his computer's OS. He'll have to be sure he has administrator access in the router to make any changes. The other option is to buy his own router.
Pedro created an account at OpenDNS but it isn't working for him. Leo says that OpenDNS can protect kids with a custom "phone book" that has a list of approved domain names in it. OpenDNS can then filter out the undesired addresses that he wouldn't want. If he inputs the router server settings of OpenDNS properly, it'll filter the traffic correctly. But if his kids have figured out how to change the settings in the computer, it can override that, unless he's made the settings in the router itself.
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.
Andrew wants to know why OpenDNS is disabled on his network. Leo says it may be that his Mac is set up to do its own DNS. He'll have to go into the internet settings on the Mac and take out any DNS entries that are there. Then he should lock those settings with an administrator password so his kids won't be able to just change the DNS to something else. He should remember that as his kids get smarter, they're going to figure a way around it. So the best thing is to talk to his kids about making good choices.
