LinuxQuestions.org - OpenWRT Adhoc / mesh network not working (with and without batman-adv)

I am trying to setup a set of computers to connect over an ad-hoc network, or mesh (on top of adhoc) using batman-adv.

The adhoc network is able to establish a station, but I can't ping one computer from another.

When using batman-adv to create a mesh on top of the adhoc network, the bat0 device never seems to have any traffic.

Here is the setup for two computers:

Code:

Computer 1:

        option device 'bat0'



config device

        option name 'bat0'

        option ipv6 '0'

-----------------------------------------------------------------------------------------

After setting up the config, I am using the following to start services:

Code:

# Load batman-adv module

modprobe batman-adv



# Replace phy0-ibss0 with your wireless interface name (use 'iw dev' to find it)

batctl if add phy0-ibss0



Activate the interfaces

ifconfig phy0-ibss0 up

ifconfig bat0 up



Assign IP address to bat0 interface (use different IPs for each device)

ifconfig bat0 192.168.2. netmask 255.255.255.0 # Use 192.168.2.2 for the other device

What is going wrong here?
