well you can take a look at this site and make your own
here or
here but ive had wireless for a long time now and unless your gonna
spend alot of money and get profesinal wirless routers and cards like the big companys do your gonna get disconnects i often loose the signil in my house in the same room it gets annoying sometimes i only use wirless when i need to
i recomend buying some cat 5 cable
and running either under ground (dig a shallow trench)
or something like that yall are neighbors so it shoudn't take to much wire
