Community wireless networking projects just got easier (and cheaper) with a new upgrade to Ewrt, the free Enhanced WRT Linux distribution, created by Irving Popovetsky and Brandon Psmythe of Portless Networks.
It modifies the popular Linksys WRT54G and Linksys WRT54GS
access points, creating an inexpensive, easy to use hotspot-in-a-box
solution with your own custom splash page. No computer necessary.
EWRT differentiates itself from the other WRT54G
distributions by providing a captive portal based on NoCatSplash and a
writeable jffs2 filesystem for storing content. [Daily Wireless]
