Tomato is a small, lean and simple replacement firmware for Linksys' WRT54G/GL/GS, Buffalo WHR-G54S/WHR-HP-G54 and other Broadcom-based routers. It features a new easy to use GUI, a new bandwidth usage monitor, more advanced QOS and access restrictions, enables new wireless features such as WDS and wireless client modes, raises the limits on maximum connections for P2P, allows you to run your custom scripts or telnet/ssh in and do all sorts of things like re-program the SES/AOSS button, adds wireless site survey to see your wifi neighbors, and more.
This firmware is provided as-is without any warranty. I will NOT be responsible for damages that occur due to the use of this firmware. USE AT YOUR OWN RISK.
Editors Note: File comes in 7z format. If you don't know what that is, you should not be playing with your routers firmware This download works for most routers but for WHR-G125 & WL520GU you might need this download instead.
