| - | The original WRT54G was first released in December 2002. The router is considered a home network device supporting, WLAN(//WiFi//), LAN and WAN. It has a 4+1 port network switch (the Internet WAN port is part of the same internal network switch, but on a different VLAN). The devices have two removable antennas connected through Reverse Polarity TNC connectors. The Linksys WRT54G series family is well-documented in [[wp>Linksys WRT54G series]]. | + | The original WRT54G was first released as a SOHO router in December 2002. The product line supports WiFi and five switched Ethernet ports. (The WAN port is part of the same internal network switch, but on a different VLAN.)

| + | For versions of the OpenWrt "brcm47xx" target prior to "Attitude Adjustment" 12.09-final, you may wish to use Broadcom's proprietary wl driver due to longstanding issues with the b43 driver in Linux kernel versions 2.6 and newer ([[https://dev.openwrt.org/ticket/7552]]). After installing the brcm47xx image, you will need to execute the following commands while logged into the router over TELNET or SSH: | ||

| + | opkg update | ||
