The Linksys WRT160NL WiFi router is equipped with a Linux based firmware by default. But, according to several users of the device, the standard firmware seems unstable.
Alternatively it is possible to install the OpenWrt firmware on the router. But only the version v6 of the router is supported and can be used together with the OpenWrt version “Backfire”. For the version v1 of the router a OpenWrt revision “Kamkaze” is available, but is still marked as “Work in Progess”.
