I used this Asus router http://www.newegg.com/Product/Product.aspx?Item=N82E16833320185&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel--Content--text-_ which work awesome with my computer but no go on the phone. My phone is a POS though so maybe thats it.
I set up a similar situation, but simply between home base and cabin - I used two Ubiquiti LocoM2 - pretty much the cheapest option, $50 each. I use them as a bridge, and I set up a $20 router in the cabin - works perfectly for me so far. Cabin and base are about 300 ft apart at least. I don't get a wifi signal on my phone right now, even though I have connectivity through my computer, I"m not sure why that is. One thing to think about is the farmwide wifi specifically for phones and what equipment may work the best for that scenario. Thanks for documenting your work!
Looks like a real improvement. I love the Farm Hack concept, but I feel like there is bit of confusion on how to use this website. I would think an improved navigation experience and some explanatory text about wiki and how to use this site would be a more pressing concern in terms of gathering more users and audience. For instance, I don't need all the subscription widgets on the right column on this page. Also, why have the +newtopic button up on the top there? Why would I do that right now while looking at a topic? And I don't need the Google analytics counter either, it is just extra data I don't have the need for. It all feels a bit frantic in the right column.
