WRT54G drops linux support open firmwares not supported

WRT54G dot NET :: Your Source for the WRT54G and the WRT Series
whoa! hold the horses, that next Linksys router you buy might not be open source anymore! This is a very bad move on linksys' part, and could mean the end of my support for the company.
I just bought a wrt54g and luckily it was the right version.

Linksys recently released their fifth version of the WRT54G. This model doesn't not run on Linksys. It runs on VxWorks which means by default flashing current firmware will not work. It's unclear if Linux-based firmware will ever work on the v5. Regardless, for the current time no 3rd party firmware will work on the version five. The serial number for version fives are CDFB. If you have bought one, we recommend returning it.
