Eero

Episode 1600

David from Anaheim, CA

David needs to extend the WiFi in his apartment building. Will an extender do the job? Leo says it will, but at the cost of cutting bandwidth speed in half, because the base station is relaying the signal and spending half the time talking to the router. Leo recommends going with a MESH router. Eero is a good one, as is NetGear Orbi. But there are plenty more. Just about every router company makes a mesh model now. 

How Can I Set Up a VPN at Home?

VPN

Episode 1600

Tom from Warren, OH

Tom wants to set up a virtual private network at home. How can he do that? He's worried about getting bit by ransomware. Will a VPN prevent that? Leo says that no. If you click on something, a VPN can't help you. But a VPN will keep your traffic private, so no one can see where you're going. But even then, it has its limitations. While it burrows an encrypted tunnel to where you're going, once you get there, it's no longer encrypted. So you have to trust that where you're going will keep your privacy. And your provider still sees your traffic.

Once you order Amazon's choice, you start getting more results like that.
