Computers continue to get cheaper and better all the time. And the ways to connect them together in networks keep improving in speed and capabilities, and dropping in price as well. Life is good for geeks.

MAXX 2400 high power outdoor access point
A weatherproof 800 milliwatt 802.11g access point, wireless bridge, and wireless client, with optional 8.5 dBi antenna.
Netgear RangeMax 240
A MIMO 802.11n access point -- this device gives you much better range and speed than an 802.11g device, and it actually benefits from walls and objects that reflect the signal around corners, to eliminate dead spots around the home, office, or (in my case) farm.
Netgear WPN111 USB Wireless Adapter
Get 108 megabits per second and up to 10 times more range by pairing the RangeMax 240 with this tiny USB WiFi device. Your laptop's internal WiFi just won't compare to the speed or the range of this little gem.
24 dBi Parabolic Dish Antenna
I share my high-speed Internet access with a neighbor 2.5 miles away, using a quarter watt access point and a 24 dBi antenna at each end of the link. Works like a charm!
