Hi all，

Now i have build a mesh network with batman-adv routing algorithm（batman-adv-2014.2.0）and Linux 3.3.8. Each mesh node have one WiFi card which is configued to the adhoc mode （according to the suggestion of openmesh website）and 11A protocol.

But the data rate between two mesh nodes is only 8Mbps，while if I configure the same WiFi card in mesh node to AP mode and client mode，the datarate between them can achive 40Mbps.

I think the reason of the low data rate is caused by the adhoc mode（my wireless driver is ath9k，the datarate of adhoc mode is slower indeed）

My questions are：

1. 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,
