1. My devices that are connected to the internet is 3 iphones, 3 ipads, 3 ipods, a playstation 3, 3 laptops, and a printer. The internet provider is Comcast and the internet cable comes through my parent's room on the second floor to a coax cable that connects to a modem. I then have a wireless router.
2.I learned that the router doesn't have to be connected to the modem. I also learned that it takes a lot of wires to connect to the internet than it looks like.
3.I would tell other people that when you are ready to have internet, make sure you have a good spot to put all the wires at because you would want place where you could have wifi connection from everywhere in your house.
