What is "hyperwrt"

HyperWRT is a GPL firmware project for the Linksys WRT54G and WRT54GS wireless routers based on the stock Linksys firmware. The original goal of the HyperWRT project was to add a set of features—such as power boost—to the latest Linux-based Linksys firmware, extending its possibilities but staying close to the official firmware. Over time, it continued to be updated with newer Linksys firmware, and added many more features typically found in enterprise routing equipment. HyperWRT is no longer maintained and has been succeeded by Tomato.
