Can You Hook up an Ethernet Cable to a Phone Jack?

Can You Hook up an Ethernet Cable to a Phone Jack : Using an Ethernet cable, connect your wireless router to your modem, plug your telephone cable into the modem, and your DSL will be activated.

Follow these steps if you are connecting your modem via an Ethernet or USB connection. Plug the phone splitter into the wall jack, and the other end of the phone cable into the DSL port of the modem.

Your question regarding telephone ethernet cables is absolutely correct. They are completely different from computer ethernet cables. They do not fit into the same ethernet hole on a wall since telephone use ethernet cables that use RJ11 connectors while computer uses RJ45 connectors.


You can use a patch cable directly between the wall jack and your PC if there’s an ethernet cable (probably Cat5) directly running from the router to the wall jack (Of course, the wall jack has to be for ethernet, not phone).


Simply plug one into the wall with your router, connect it with an Ethernet cable, and plug the other into the wall with your far-away devices. Note that you have to plug the cables straight into the wall; you cannot use a power strip or extension cord.


The wires must be color coded: the blue ones first and then the orange ones second. Nowadays, Cat5 cable is commonly used instead of wire for telephony.

There are eight wires (four pairs) on Ethernet Cat 5 cables, set to different standards, but only four (two pairs) of these wires are actually used. One pair is used to transmit data, the other pair is used to receive data.


A good number of ways exist to connect to the Internet, including ordinary modems, local-area network connections in your office, cable Internet connections or digital subscriber line connections (DSL). DSL is a very high-speed line that’s like a regular telephone line.


Using the standard phone cable, connect the modem to your phone jack. The wireless router should begin distributing wireless signals as soon as it is plugged in. Most routers include Ethernet port if hard-wiring your desktop computer is desired.


I heard a question about whether Ethernet Cables and Network Cables are the same. The answer is that Ethernets and Network Cables are the same. So any cable that allows you to connect with a particular system or device within a local local area network is basically the same.

What do I plug Ethernet cable into?

  • Plug one end of an Ethernet cable into your modem.
  • Plug the other end of that Ethernet cable into the Internet, Uplink, WAN, or WLAN port on your router.
  • Plug in your router.
  • On your computer, click Start, and click Shut Down.
