Hi someone's situation:

They are looking at getting internet but the recption may be poor.  I plugged in a old ADSL box I had and walked around with my Smartphone. 

So they have run extension RJ11 telephone cable to other rooms.  Possible to use this cable as a network cable (at a reduced speed) and plug it into the main router and add a router in this other room to extend the WiFi?  Are there RJ11/RJ45 adaptors available on the market?

Saves me rewiring a new cable or two and crimping ....

In theory yes as 10/100 only requires 2 Pairs, Although alot of telephone extension cables are only 1 pair (All that is required for telephone)

I suppose you could try and use it as a draw cable.
Dont bother with RJ11 cable for Ethernet.

A better option would be a powerline adapter. You can get up to 500Mbps symmetric, most likely between 50Mbps - 100Mbps though, and if you're really unlucky, 5Mbps.

Powerline hmmm the house is over 100yrs old. Do you need 2 power outlets for each point or just one?

RJ11 is a telephone connector. What sort of cable did they run?

Assuming it's standard 2 pair phone cable it's only cat3 rated, so isn't technically capable of 100Mbps Ethernet. If it's flat cable it won't work at all.

yep that was what I was about to say the RJ11 is a type of connector not a Cable
type but

- Flat 2 pair ribbon cable - voice only
- two pair homelan (white & blue , Orange & Blue ) 10/100 @ best just 10 @ worst
- three pair (Twisted pr) phone cable (white & red , Green & blue, Orange & Black) 10 maybe or nothing

ADSL will work over the last two and very poorly over the first. (no long extn cords)

VDSL will work poorly over the last two ( that is why you are best to have cat5/6 cableing for VDSL)

rayonline: Powerline hmmm the house is over 100yrs old. Do you need 2 power outlets for each point or just one?

1 power outlet at each end for the powerline adapter, then any extra devices will need their own outlet. And the age of your wiring won't affect it so much, just the quality of the connections and the distance between the points.

Thanks all. Yes telephone extension cable don't know how many wires inside. Prob cheaper to just wire the 1 or 2 cat5 then.

Telephone wall jack to main router is fine Vdsl or adsl. Its that they have to have more access points. Everyone would be using wireless on their devices no Ethernet. Ethernet cable to APs I don't think the wireless signal can reach the APs....
