I used b43 chipset wlan cards(Asus WL-138G V2 PCI card) which are known to work with open11s. I could make the mesh interface, and see neighbor nodes by 'iw dev mesh station dump'. But its output is slightly different from open11s manual like this. root@ybim-desktop:~# iw dev mesh station dump Station 00:1b:fc:3e:52:44 (on mesh) inactive time: -66040 ms rx bytes: 0 tx bytes: 0 And what is serious is that when I execute the command 'iw dev mesh mpath dump'. I lose my ssh connection, and the system gets strange. The symptom is the same in both cases, wireless-testing and compat-wireless. I got below messages through dmesg when I used wireless-testing. Actually, I used following commands to create the interface. export MESH_ID=1023 iw dev wlan2 interface add mesh type mp mesh_id $MESH_ID ifconfig mesh down iwconfig mesh mode ad-hoc essid open11s channel 3 ifconfig mesh up ifconfig mesh 192.168.4.2 But, someone said to me that to use the command 'iwconfig mesh mode ad-hoc essid open11s channel 3' is not good way because it can make a problem with mesh interface mode. So I changed the commands like this export MESH_ID=1023 iw dev wlan2 interface add mesh type mp mesh_id $MESH_ID iwconfig mesh channel 3 ifconfig mesh 192.168.4.2 Then I couldn't even make any connection between nodes, that is, I could not find any node when I typed 'iw dev mesh station dump' I think I correctly installed following open11s manual, and the hardware is ok. But I cannot figure out the reason. Any ideas? Thank you.
