Linksys WRT54G (and variants WRT54GS, WRT54GL, and WRTSL54GS) is a popular Wi-Fi capable router from Linksys. The device is capable of sharing Internet connections amongst several computers via 802.3 Ethernet and 802.11b/g wireless data links.
The WRT54G is famous for being the first consumer-level network device that had it's firmware source code released to satisfy the obligations of the GNU GPL. This allows programmers to modify the firmware to change or add functionality to the device. Several development projects have been started to provide the public with enhanced firmware for the WRT54G.
Linksys routers that have been used with the wirds.net project are
- WRT54G versions 1.0, 1.1, 2.0, 2.2, 3.0, 4.0
- WRT54GS versions 1.0, 1.1, 2.0, 2.2, 3.0, 4.0
