Fonera

  • Freischalten Channel 13
  • Version von FreiFunk (Sven Ola) wien unter Fonera mit OLSR beschrieben ist
  • Kamikaze, da funkzioniert das nicht so wie bei der Freifunk Firmware von Sven Ola. Hier ist für die Freischaltung nur ein Eintrag im /etc/config/wireless unter config 'wifi-device' und zwar option 'country' '276' notwendig. 
bei mir sieht es so aus

cat /etc/config/wireless

config 'wifi-device' 'wifi0'
        option 'type' 'atheros'
        option 'distance' '15000'
        option 'diversity' '0'
        option 'country' '276'
        option 'channel' '13'

config 'wifi-iface'
        option 'device' 'wifi0'
        option 'network' 'wlan'
        option 'mode' 'adhoc'
        option 'mcast_rate' '5500'
        option 'encryption' 'none'
        option 'rate' '5500'
        option 'ssid' 'v13.freiesnetz.www.funkfeuer.at'
        option 'bssid' '26:A7:D4:E4:4F:4D'
