How can a computer be hooked up to DSL in multiple rooms?

Question

I know nothing about DSL. One of my friends has a modem and computer in one room, and what appear to be a phone jack and maybe a splitter with one end for DSL in another room.

How would getting a computer on the Internet in the second room work? Can he plug something in to the second jack, or will he have to run Ethernet to the room/use a wireless modem?

Answer 1

You can only have one modem connected to one DSL connection, you would need to have your friend connect a Wireless Router to the modem, then you can share the network connection either wirelessly or use a ethernet cable.

The modem may or may not have a wired and or wireless router built in, you would need to post the model for us to know for sure.

Answer 2

That splitter is probably a DSL filter for the phone on one side and an unfiltered jack on the other side for a DSL modem to plug into. It really should be only a single jack filter since you can only have one DSL modem on the line. It may be two filtered jacks, though. It should be labeled.

You will need to use Ethernet or Wi-Fi to add additional computers.
