My home network M2 Harrington

The devices connected to my L.A.N is 4 Laptops, 3 phones, an Xbox, a printer, and an iPod. While i was learning about Wireless internet i need no idea there was such a thing as a fire wall. I learned that a fire wall is something in your computer system that protects you from unauthorized websites. I would tell people that they really should know about what kind of modem or router they have in case there internet gets hacked into or it gets lost, then they need to know how to restart their WiFi.
