Connecting a 2nd router to an summer house

Hello - I am hoping that some can help me.

I have a summer hose at the back of my garden, when I had this build I had a electrician run cat5 cable from the back of my main BT phone socket to the summer house. He tested the socket in the summer hose with a phone and it worked. I have now purchased a TP-Link wireless n router and want to make it work in the summer house. I have a BT smart hub connected to the master socket in my house for internet in the house. How can I get the router woring in the summer house?

Google for: "configure a router to be an access point"

There was a description on this website, but at the moment I can't find it.

The Cat5 cable is carrying the phone line or an Ethernet signal?

If phone line then you need to rewire it to handle Ethernet, so ideally adding an Ethernet socket and making sure the pairs are wired correctly at each end.

You have to lose the phone in the summer house, and change the wiring to be an Ethernet connection. As MrSaffron says, you have to unwire this from the back of the master socket, and attach a plug, and plug that into the BT smart hub, and the other end can then be plugged into your TPLink router.

You can't have two routers on a single phone line.

Thanks Michael_Chare, the 2 router can act as an access point as the cat5 cable that's connected to the house is in a BT phone socket, not in the BT hub router.

Thanks MrSaffron, I will check with the electrician as I did tell him the line so I can have internet at the back of the garden.

Not all electricians will understand how to do this. Its not really an electrician's job.

Thanks jchamier, I will have to get the electrician back to do this.

As others have said the extension socket in the summer house has been wired for a telephone and not the internet.
You need to tell the electrician that you want the extension to be a "Network Access Point". Then you can attach the TP Link router and configure it.
Ask the electrician first if they can do this as they will have to disconnect the extension from the back of the main BT phone socket and attach an RJ45 plug to it. To do that the electrician would need a crimping tool. The RJ45 plug would then need to plugged into the back of the BT smart hub.
The electrician would also need to know the wiring sequence from the RJ45 plug to the phone socket in the summer house. If they get the sequence wrong at either end it won't work.
If the electrician doesn't normally do this sort of thing my guess is they won't have a crimping tool or any knowledge of the wiring sequence.

Better an RJ45.
