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.
