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'
