Wireless Internet, Routers, USB adapters, expanders

Hi there.

Iv had quite a headache with my wireless internet for some time now!
Im on my 3rd router in 3months and today it is the DrayTek Vigor2800VG. It is said to be a very reliable router with a good signal and stuff.
(note: I AM NOT TECHNIC LITERATE)

It works briliantly when wired with the CAT5 RJ45 Cable, but when it comes to stand downstairs, in between both my houses - the signal fails to please me.

I looked and read around, and even summoned the assistance of my local computer technician and came to the conclusion that an investment in a signal range expander would be the wisest choice. I have two Computers in my house, One upstairs, and the other a laptop. In the other family house next door - I have 3 laptops one desktop. some have Cards some have usb adapters.

At times the signal is great - but at other times the signal is poor. If I were to place the router in the dining room adjacent to the wall of both houses, drill a hole through the wall, place an expander, put the RJ45 cable from the expander to the router on the other side, I would assume the signal would be good on the other side?

Due to this reason, I am asking my fellow sythe.org members to aid me in this wretching pond of misery.
I need to know the details of how these Networking systems working when the Expander comes into play... I assume it goes under the tab WDS?

I would like to know the best available Expanders for a good price...
and The best available USB adapters for a good price.

And oh... Im in the UK.

(wow i sounded like a nerd... dont like this acting at all haha)

Cheers for reading
