This project is to build an enhanced firmware for Linksys WRT54GS (versions 1.0 to 3.0 with 32MB RAM/8MB Flash) and similar routers, offering multiple Internet service providers Load Balance and Server Load Balancing capabilities (Layer 2). The Server Load Balancer technology is from by http://www.linuxvirtualserver.org/.
CoovaChilli is an open-source software access controller, based on the popular ChilliSpot project. CoovaChilli is the continuation of the great work of the ChilliSpot project. It is a feature rich software access controller that provides a captive portal / walled-garden environment and uses RADIUS for access provisioning.
CoovaChilli is an integral part of the CoovaAP OpenWRT-based firmware which is specialized for hotspots.

CoovaAP is an OpenWRT-based firmware designed especially for HotSpots. It comes with the CoovaChilli access controller built-in and makes it easily configurable. CoovaAP is perfect for just about any HotSpot application – from WPA Enterprise (with RADIUS accounting) to Free WiFi with Terms of Service acknowledgment to commercial HotSpot captive portal applications. Use the embedded captive portal for a simple self contained HotSpot or use your own captive portal and RADIUS back-end.
