Linksys is offering their Linksys EasyLink Advisor (LELA) Setup Wizard as a native Mac application for managing some of their more recent router models. Similar to the Airport Setup Utility the EasyLink Advisor allows users to setup and manage their Linksys router based networks without going through the web page based setup that Mac users have traditionally had to suffer.The LELA Mac Wizard is compatible with the Linksys WRT54G2, WRT111, WRT160N, and WRT310N routers and will be on on the setup CD included in the retail packaging.

Update: Thanks to a reader, found a download link (select version 1.0 from the dropdown menu to reveal it).
