On my L.A.N I have a pc connected by ethernet, 4 laptops, an Xbox, 2 ipads, 4 iphones, and a chrome-cast. In the process of this I also moved my router and modem from the first floor to my room and also learned a lot about my network. Primarily I learned in class, and in my tampering how the cable systems actually work. I was surprised to discover that the cable we use for cable has to be plugged into the modem. I would tell other people to understand what each wire does that goes in and out of your router and modem. Also if you have comcast, call them every two months or so to prevent them from screwing you over (sometimes they randomly change your bill.
