Hello, so I have been planning to move another PC into my own room which happens to be about 30 feet away from my router. Since I don't want to have Ethernet chords running throughout my house, I was wondering if there is anyway i can add a modem in my room or something to have a place to plug my PC into a Ethernet port. It would also be good if i can have more than one Ethernet port to plug my Xbox in as well. By the way I have At&t internet connected through a DSL to my phone line. Any help with this would be appreciated.
