OK

To cut a long story short,

My new house cannot get broadband via the phone line (I live in the countryside,)

However, my landlord, who is my neighbour, can, and has a wireless router on my side of his house, which I can connect to in my house on my laptop, but only get 1 bar. If I put the laptop on the windowsill facing his house, I get 4 bars.

My question is this:

Someone said to me that I can use my previous ADSL Wireless ROuter to connect to his WIFI connection and then relay it around my house.

How do I do this?

my wifi expertise is low-intermediate: I've seen "wifi extenders" online, but can't help believing that they're not just glorified routers...

Please help!
