Setting up a second router using telephone port

baarrrneeee · Sep 30, 2017

Hi there!

I'm hoping someone can help me learn if this is possible.

I have a wifi router set up on one end of the house, and would like to set up another on the other side that (ideally) I can use to plug the ethernet in to my PC.

Problem is, the wifi doesn't anywhere near reach this side of the house (walls made of lead or something), so range extenders won't do the trick.

I do, however, have a phone port in this room (Like this: https://support.zen.co.uk/kb/Uploads/Images/FTTC/BTEquipment/FTTCNTE5-kb.PNG). Is it possible to use this as an ethernet cable, plug it in to a seperate router and ethernet it into my pc?

Cheers

Odds are not good but if you are lucky it might be possible

What you are going to have to do is convert the phone jack to ethernet. The most important issue is going to be are the wires capable of supporting ethernet. You will need at least 2 pair and that will limit you to 100m 4 pair will get you 1gig but the wire needs to be cat5e or better to get 1g. You can sometime get 10mbit working on 2 pair of other quality wire at short distance.

Next the wire needs to be point to point. If it is daisy chained to multiple jacks you must disconnect those and leave only a direct path between the 2 jacks you want to use.

You would then replace the ports with standard rj45 ports using the wires in the wall.

I guess you can pull the wall plates and look and hope to get lucky.

If not you could consider powerline networks instead. They technically do make a device that will use actual phone lines, it is a form of private dsl, but it is rather expensive and it is relatively slow compare to something like powerline.

Thank you for your response!

I ended up going with a powerline network as you suggested. Working great so far!
