wifiroamd is a background program which tries to just do the right thing to bring up your wireless network. Simple, yet customizable init.d-like scripts are used to determine which networks are preferred and to do things like set the ESSID or WEP keys. Other advanced functionality such as bonding of wired and wireless devices is also automated. wifiroamd is an engine for the handling of connecting to wireless networks. It is entirely command-line based, and meant to run in the background without interaction.
