And you can't run a cable over the next-door neighbour?

One access point may well be enough if it's mounted on the outside of your house on a wall facing or alongside the recipient.

This is the cheaper version at £35 (2.4 GHz only)

And you can get cheap access points on Ebay for a tenner up. I won't recommend one as some of them are locked to their own management software.

If your neighbour can also use an external USB wifi receiver near his external wall facing you.
