Routers that work with DD-WRT
Router Recommended
The DD-WRT community recommends the Linksys WRT54G, WRT350N and WRT600 N, Buffalo WHR-HP-G54 and the router WL-500G and Asus WL-520gU. These routers have been found to be 100 percent compatible with the DD-WRT firmware and showed no blinking problems. The Buffalo has the best range. Asus routers have additional USB ports that allow you to connect drives or printers in a network. The Linksys WRT350N and WRT600N use the fastest 802.11n specification, in addition to the available USB ports. Enterprise router is a basic product for any business/enterprise.
