Re: [PLUG] Linux on Router Question

For most Linksys and some other brands of routers (e.g. Buffalo), it should be possible to flash them without using the web interface, for example if the interface is unstable or unavailable.

Unless you disabled the boot_wait setting, each time a router boots up it will listen in a specific way for you to send an image to it via TFTP for a few seconds.  You have to give your computer a certain static IP, turn the router on and keep trying to update it, and it's not easy since it's only available for a few seconds.  Sometimes you even have to plug your computer into a specific port on the router.

The settings for your specific router/firmware will need to be discovered via research.  This isn't an easy method, but it will recover some routers that couldn't be fixed otherwise.

See http://wiki.openwrt.org/toh/linksys/wrt54gl#using.the.tftp.method for an example.
