Do you have line of site between the two? If so here is what I would use http://www.amazon.com/Ubiquiti-Nanostation-NSM5-802-11a-Hi-power/dp/B0049AVWAO This is what I use to have WiFi in my shop. They will go a long ways if you have line of site. They will also go through some tree but you won't get as good of range. They do take some setup. They are slightly harder to setup than a wireless router, but there are some videos on youtube that can help you. You need two of them one at each end.
