Is there any way we can convert normal cat 3 four wires telephone cable to Ethernet cable...

I need my existing secondary concealed telephone wiring as a LAN cable

AFA I researched 4 wire can support upto 2 mbps only..

Also couldn't find any rj11 to 45 converter..
So crimping needs to be done I guess

Has anybody tried this..
Or any inputs regarding the feasibility
 
Not possible.
Cat 3 = 2 pair
Ethernet cable (Cat5/5e/6) = 4 pair.

Incorrect !
Cat3 = 4 pairs = 8 wires

Cat3 = 4 pairs = 1st gen ethernet cable that supports 10mbps till 100 mtrs.
technically, upto 100 mpbs ethernet uses 2 pairs out of 4. But if you have a category 3 written on the cable then it is 4 pairs only, maybe the guy who crimped it just terminated 2 pairs for phone application and discarded 2. You just need to change the RJ11 connector to RJ45 on both sides.

It has four wires.. Two pairs.. Doesnt seem like a twisted pair.. The wires are separate..

But won't it need crimping
 
LAN connection needs total 4 wires.

One for read and one for write for each end.

So for two ends - total 4 wires.

All you have to make sure is that proper crimping is done with proper color. But may not be easy
 

See this image, when you crimp, let unused areas have NO wire.

Rest of areas use same colors at both end.

Its not necessary that you need exact same colors as in image below.

Colors are standardized just to make sure there is no confusion in future.

You can try, but keep in mind that the signal/bandwidth will have a massive drop from room to room using this '4 wire' cable. Ethernet cables have more twists to improve signal/bandwidth.
If it works, then nothing like it. If it does not work, then wifi is an option.
 
In the context of telephone cables, Cat 3 can come with 4 cores/conductors. So, don't worry about it.
Crimping - It's a little troublesome, but doable.
 
i was able to get it right the first time. had to watch tutorials on youtube and pause them several times to get it right. end result is crude but it works!
 
Yes its easy if u watch videos and do as per video.

4-5 years back my friend was setting up new office. And electrician asked him for 50Rs per crimping point! (total 6) (cables were already laid)

I told him forget it we will do it on our own!

We bought new crimping tool for about 150Rs and bought 15 plugs. (all done with just 1 bad crimping)

Overall:
  1. He saved about 50-75Rs.
  2. Got own crimping tool
  3. Learnt to do it well
  4. Will save money in future too!
  5. Some time lost but worth it

Then it's not cat3. Pls show me one cable with 4 cores and cat3 printed on it. 😀
