Steve has his own Wi-Fi router but his cable company just gave him a new router with Wi-Fi built in. Is it more secure? Leo says they're about the same security wise. He'll want to be sure to turn on WPA2 password protection. And often routers have security flaws and rarely get updated. So Steve should make sure he has his router firmware updated.
What about using Wi-Fi extenders? Leo says that all extenders need to be connected to one master router, which will do all the work. Every other router should be in bridge mode to repeat the signal. And make sure they're all the same manufacturer.
