Wireless N router, long range/high power - reccomendations?

[clay]

go with wired. Less headaches, fast connection, and no mucking around with wireless which will be finicky. It may cost more now, but if it is used for anything crucial at all, wireless is just going to be a pain in the butt.

Run 3 data cables for some redundancy (preferably in a couple of different locations in case one is ever severed), and never look back.
