Question: How do I manually set my Cell Id? I have tried the following code
sudo iwconfig wlan0 ap 02:12:34:56:78:9a but it randomly resets the Cell Id to a different value.
I am trying to create a wireless mesh network using some raspberry pi devices; http://www.open-mesh.org/projects/batman-adv/wiki/Quick-start-guide.
It wouldn't work and whilst troubleshooting the problem, I find that I can't even get a basic ad-hoc network going. It doesn't allow me to manually set the ap (cell id) nor does it allow you to set an essid that is already in use by another rpi device.
Everything is connected out of box. Rpi are set up using NOOBS with raspbian. I ran apt-get update, upgrade, installed batctl and enabled batman_adv module on boot. I have limited experience with linux and rely heavily on google for answers.

How I set up the network:
ifconfig wlan0 down iwconfig wlan0 mode ad-hoc essid mymeshnet channel 1 ap 02:12:34:56:78:9a ifconfig wlan0 up
ifconfig wlan0 inet 192.168.2.1/24
ifconfig wlan0 inet 192.168.2.2/24
iwconfig on rpi(a):
wlan0 IEEE 802.11bg ESSID:"mymeshnet" Nickname:"<WIFI@REALTEK>" Mode:Ad-Hoc Frequency:2.412 GHz Cell: 02:11:87:75:18:01 Bit Rate:54 Mb/s Sensitivity:0/0 Retry:off RTS thr:off Fragment thr:off Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0
iwconfig on rpi(b):
wlan0 unassociated Nickname:"<WIFI@REALTEK>" Mode:Ad-Hoc Frequency=2.412 GHz Cell: Not-Associated Sensitivity:0/0 Retry:off RTS thr:off Fragment thr:off Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Searching through similar questions I have tried using different essid and using
iwlist wlan0 scan to sync the cells but still no gas.
Thank-you for reading this lengthy post. Any help would be appreciated.
