web user interface served by a light web server software running on the device. It is possible for a computer running a desktop operating system with appropriate software to act as a wireless router. This is commonly referred to as a SoftAP. In 2003, Linksys was forced to open-source the firmware of its WRT54G router series (the best-selling routers of all time) after people on the Linux kernel mailing list discovered that it used GPL Linux code. In 2008, Cisco was sued in Free Software Foundation, Inc. v. Cisco Systems, Inc due to similar issues with Linksys routers. Since then, various open-source projects have built on this foundation, including OpenWrt, DD-WRT, and Tomato. In 2016, various manufacturers changed their firmware to block custom installations after an FCC ruling. However, some companies plan to continue to officially support open-source firmware, including Linksys and Asus.
