Make your router run on VTEC by injecting it with Tomato Firmware. Tomato Firmware gives you excellent tools such as being able to monitor bandwidth consumption, boost WiFi signal, track results with graphics and much more.
This upgrade is great for older wireless routers with ddwrt firmware. Tomato firmware runs on Linksys' WRT54G/GL/GS, Buffalo WHR-G54S/WHR-HP-G54, and other Broadcom-based routers.
