Can someone give me a bit of background about wireless?

Forget wireless.

My house had thick walls and it was a total pain to try to set up. I now use a BT wired broadband router and a dlan homeplug AV plug. These adapters can be moved about (plugged in anywhere in the house with a power supply) and then are connected back up to a laptop. You can buy any number of adaptors and so several laptops and computers can use internet at once. They will even work in a barn/shed provided you have a power supply. They are a bit pricey but easy to use and safe.
