Linksys last month switched the standard model of its ubiquitous WRT54G wireless router from Linux to VxWorks, starting with the “series 5″ version. Now, Linksys is shipping a Linux-based WRT54GL model that it says it created specially for Linux hobbyists, hackers, and aficianados. The L version is identical to the “series 4″ WRT54G units that Linux hobbyists have long enjoyed hacking, according to the company.
