In my homenetwork the internet comes from a Comcast ISP connected to a router and a router/modem combo through a Ethernet wire. My desktop, two TV's, Wii, Sonos sound bar, Blu-ray, and stereo speakers are connected to these devices. the gadgets with WiFi are four cell phones, multiple home phones, two Ipod-touches, four laptops, three kindles and a kindle-fire. I learned that my internet is a lot more complicated than I thought. I know that I probably would not be able to survive without it so I think that learning more about my internet would be a good to prepare, just in case something happens.
