LAN over RJ11?

[PVTD]

Hy,
My parents run a BnB in Tuscany and we have had some trouble with networking. Not only are the walls about 50cm thick solid rocks, not bricks, but using power lines is impossible since every room has its own power switch board (or w/e u call it) and the distances are just way to far (its a fairly big place).

When they restored the building, the idiot Italian electrician thought UTP cables are those cables phones use, so we have the entire building wired with RJ11 cables, all going to a central room with a internal phone thingy to call from one room to another (not used at all).

I was wondering if its possible to use the RJ11 cable as alternative to RJ45... I don't care if its 100mb/s since... Well... Its Italy, the stonage country where internet is still at "20/1" (in reality 1/0.01). As long every room could have its own AP, and every teenage can post selfies on Facebook, and every parent can enjoy their Holliday's instead of hearing internet complains.

If so, can u tell me what I'd have to search for?

All RJ11 connectors are separate, just FYI.

Yours,

Don't try to fudge around the crappy wiring from the last guy. Do it right.

Use the existing cable to (try to) pull actual Cat5e cable.

RJ11 (phone) cable is cat 3. The twists are very loose - about one twist every 3-4 inches, vs about 2 twists per inch for cat 5. This makes it much more prone to noise, which isn't an issue for voice comms (100-3300 Hz), but can seriously degrade ethernet (100-350 MHz)

I tried running a network signal over some cat 3 cable once without any success. You can try it if you like (connect the wires to pins 1, 2, 3, 6 on the RJ45 jack). But USAFRet's suggestion is the best solution.

You may get away with running 10mbit/s but that's about it.

A CAT3 cable is also an UTP, so...

Thank you for all your answers.
Most of you say the noise ratio will be higher then ussual, but we are talking GPRS speeds here (2.5G).
Will this impact an already slow and unstable network? My original thought was to pull cat cables, but the cost of it would be huge :S...
I am talking about 2-300 meters of cables in total.
The man hours included, I'm affraid to ask for a rate haha!
But if it results in constant time-outs, I guess i have no choice.

You might as well try it. You want to remove the rj11 use rj45 and you must have at least 2 pair of cables. I would use a switch where you can set the speed and force it to 10m just to improve you chance.

You never really know when you use non standard wire. I have actually used a 20ft cable made from wire meant to put in door bells when I was desperate. It actually ran at 1g but we only used it for a couple of hours until someone got us a real cable.
