Linksys has sold a bazillion of the old WRT54GS routers. It’s probably due in some small part to the many alternative firmware upgrades you can put on the device to increase its capabilities in a number of innovative directions. The most recent versions of these devices are somewhat less hackable though. The series 5 devices have shifted from using Linux to using VxWorks, and have cut memory down to 2MB of Flash and 8MB of RAM, instead of 4MB of flash and 16MB of RAM for earlier Linux based devices. But to placate the hacker market, Linksys has released the WRT54G”L” which retains the larger memory spaces of earlier models. How long will it last? Hard to say, I’ll be watching this experiment to see how it goes.
