Linksys RVS4000 specifications & details


Here's as much information as I've managed to gather about the Linksys RVS4000 router. I'm hoping this will help or motivate someone to port emdebian or dd-wrt to it.
If you're in Australia and you manage to get emdebian running reliably on this router, I'll send you a case of beer.

If there's any more details you need, flick an email to
