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

I am not sure that's possible.

Why not buy a new Ethernet cable?

I will need a 20-30 m cable and run all the way from bedroom to hall.. Which won't be feasible

Wifi setup would be better feasible.

You need to connect your HTPC with it?

general opinion is that one needs at least 5mbps for smooth full HD streaming.

4 wires cable ? - Ethernet Card - Networking
Hi everybody and thx for your help. I have made some new tests, and I have found the bug :)
I have made a new cable with a real cat5 using only 4 wires and it works great. But if I use a phone cable with the same wiring scheme, nothing works. I guess the signal disapear too fast in the wire due to the electrical conditions of the phone cable (limited freqency). So I have to find another way to wired my house.
