Freifunk Firmware (1.2 or higher) - Howto set a fix BSSID

This article describes how to use the new option within the Freifunk Firmware (Version 1.2 and higher) to set the BSSID on your wireless LAN.

Watch Out: Allnet and Siemens SE505 do NOT like the fixed setting of the BSSID. Be careful with such adevice and a Freifunk Firmware Version below 1.2.2. You have been warned ! The current Freifunk Firmware with set BSSID is tested on the following devices: WRT54Gv1, WRT54GSv1, WRT54Gv3.1 and WRT54Gv2.2.

1. 
   Install FreifunkFirmware 1.2 or newer on your WRT Router/AP. Freifunk Firmware is available for download from http://styx.commando.de/sven-ola/ipkg/
   You can just upload the Freifunkfirmware to the original linksys firmware update page.
   


2. 
   Go to the Webinterface of your WRT with a browser. If it's fresh (never configured before) it will be at 192.168.2.1 (IP). Configure your PC accordingly (e.g. with IP 192.168.2.2 and Netmask 255.255.255.0)
   


3. 
   Login to the administativ interface of your Freifunk WRT at: http://$lt;yourWRTIP>/ with user: "root" and password: "admin". Go to the wireless configuration page and enter the BSSID of your choice. Note: Your WRTs will only be able to communicate if SSID and BSSID are the same on every single one !
   Do not forget to submit the new settings and to reboot afterwards.
