Victoria from Pasadena, CA

Victoria wants to know about WiFi extenders. Leo says that WiFi extenders help give better coverage in the home. WiFi doesn't travel well through walls and people. So the best way to improve WiFi is to place a router up higher in the house. Like on a shelf. It's also a good idea to use a router that is dual-band. Let smart devices use the 2.4 band, while you use the 5.0 band.

Rudy from Montreal, Quebec, CAN

Rudy wants to know how secure public apartment wifi is if everyone is using the same password? Leo says it's not secure at all. What it means though, is that anyone who knows the password can use the wifi. But it also means that if someone is malicious, they can use hacking tools to gain access to other people's computers and data. That's why Leo says that a VPN is a must for a situation like this. Or at least only surfing to HTTPS websites only, so the traffic is encrypted. Another option is to use a travel router. It's designed to join a public network and provides a barrier like a VPN.
