[SOLVED] Is it possible to use Ethernet through an RJ-11 port?

[sphax]

I recently moved into an apartment complex where the buildings are fairly old. There are not any RJ-45 ports. There are only coaxial and RJ-11 ports (I am not allowed to convert any ports, obviously). My internet modem is connected via coaxial, and my router is connected to it via RJ-45

I’d like to connect my PC via ethernet, rather than WiFi, but unfortunately, there are not any coaxial ports near the place I have my desk. Therefore, I have to place my modem and router elsewhere. There is an RJ-11 port right there, though. If I got an RJ-45 to RJ-11 adapter cable, would I be able to use the RJ-11 port as a makeshift ethernet port for my computer? If so, would this affect internet speed?

When posting replies, please keep in mind that I only know the basics for this type of thing, and I will not understand anything explained in complicated terms. I would greatly appreciate some help though! 😀

Unfortunately, ethernet requires a minimum of 2 pairs of wires (4 wires), while phone jacks are typically only 1 pair (2 wires). However, if you really, really want wired, you can use a vdsl ethernet extender on both ends of that single pair of wire and get up to 1.2Gbps wired. The ones I've used are from a company called netsys direct and were their older model limited to 200Mbps, and other companies make the slower models:

It's not cheap though at $400.

Rather than go into any detail why don't you take the jack apart and look at how many wires there are. You need at least 4 connected to jack to even think to do strange stuff like use rj11-rj45.

There are a couple other issues though. First the wire must be the proper type. Older building you will find the older red/green/yellow/black cables. They many times use screw connection on the back of the jack. This type of wire will not work for ethernet.

Next phone jacks tend to be daisy chained room to room. They appear as one long wire with multiple jacks on it. Ethernet is point to point. If the phone jacks run back to a central closet you have a better chance. Running it on daisy chained tends to not work but might if the rooms have a direct hop in the chain.

Likely the cheapest is going to be powerline converters. You could also consider Moca to run on the tv coax but that is not as cheap.

How did I forget about powerlines? This is easily the quickest and best solution if it works well, and I think it should from the description of the place.

Yeah, I forgot about them at the time of posting this as well, but remembered later. I actually used them in my old place a while back, and have an extra set. That’s probably what I’ll end up using. Thanks for the help!

Sweet, hopefully those powerlines do the trick. They're a neat technology that solves issues like this quite easily.
