Good write-up for DIY WIFI Repeater:
First camping trip this year I was able to test out my new WIFI setup. Could not connect directly from my laptop.
Linksys WRT54G flashed with DD-WRT
SUNHANS 2 Watt 2.4 Ghz Booster with 6dbi attached antenna
This allows for multiple devices to be connect to WIFI. All I have to do is connect to my router and scan for available WIFI and connect. After that all devices can connect to internet via my repeater. No changes to devices.
Plans to add external antenna for better signal.
