I moved into my bungalow 3 years ago. The bungalow had been extensively extended going from a 2 bedroomed 1 lounge to a 4 bedroomed, dining room and 2 lounges. The extension is powered from an additional consumer unit (fuse box). The telephone master socket is at the front of the bungalow where the TalkTalk router is placed. I'm unable to get a decent wifi signal at the back of the bungalow. I have tried using wifi extenders that utilise the electrical power sockets but these don't work when going through the second consumer unit. When I contacted TalkTalk about this issue they recommended that I purchase their latest most powerful router and I would get a wifi signal even in my back garden. I bought this router at a £30 cost but there has been no improvement in the wifi signal in my back lounge. With also having my original router I went online and renamed both router I.D's the same, also with the same password. My thought was that I would have both routers powered up and my mobile phone wouldn't keep searching for the strongest wifi signal as I made my way from one end of the bungalow to the other. I ran a new telephone cable from the master socket to the back lounge with the intention of powering up both routers. The old router now in the back lounge would also be connected (wired) to the TalkTalk TV box.
When I have both routers on the old router can't connect to the internet even though the wifi signal strength is at maximum. When I power down the router in the front lounge I get internet connection in the back lounge.
My question is this.
How can I have both routers powered up and on at the same time?
If this is not possible is there anything else I can try
