Wireless Network Extension

My router is the Linksys WRT54G2 V1.5 Wireless-G Broadband and I think it's got excellent range and quality; however, I'm not home much and I want to share my internet with a neighbor who's about 700 ft away. He will be using a laptop, ACER NV53A.

What are my options with a $25 and/or $50 budget?

Looking around, in my far-from-expert opinion, he can use: http://www.amazon.com/AU-4622-Wireless-Detachable-AP-Interface-Smartphone/dp/B003YEWG38 for $23 to connect to my network.

Will that work? It's a direct line-of-sight connection, with no obstructions except that my router is behind a window. I'm in a mobile home, he's in a camper and he uses his laptop in his front yard on a semi-picnic table, but it's still a straight shot from my window/router to the table where he uses his table.

No, it will not work.The normal range of a wireless g router is about 300ft outside with no obstructions on a good day. 700 ft away is just to far even if you both had a big antenna at both ends. And at 50 bucks budget you can rule out any directional antenna that you could get.

I know you are trying to be a nice guy in helping a neighbor out but have him go get his own internet. By you giving it away your neighbor can do what he wants on the internet and if he does something bad (ie child porn or something like that) you would be taking the blame for that. I personally don't want to be held responsible for someone else mistakes. Not saying that your neighbor is shady or anything but it is something to consider when allowing someone else access to your internet.
