How can I raise the data rate to 30M+ if I use the adhoc mode？
As far as I know ath9k works usually well in adhoc mode and can reach much higher datarates. In any case the problem is likely to be ath9k specific, so batman-adv can't do much for that. > 2. can I use the monitor mode of WiFi card with batman-adv？someone tells that > it can be done，but when I batctl addif wlan0 （wlan0 is configured in > monitor），it shows that interface type not support by batman-adv. > you cannot add a monitor interface to batman-adv (as explained by the message), but you should be able to create to interfaces: an adhoc one to use with batman-adv and a monitor one to use for your purposes. This is what most people do. Cheers, -- Antonio Quartulli
