That can be a lot of things, some possible pitfalls: 1.) Antenna diversity Do you have all antenna outputs of your wireless nic connected to an antenna? In our case ath5k would randomly choose the output antenna for broadcast (e.g. OLSR) traffic, but only one antenna is connected. Thereby OLSR was losing too much packets and links did not pass the link quality threshold. In our case we had to change antenna config to "AR5K_ANTMODE_FIXED_B" in ath5k_config of drivers/net/wireless/ath/ath5k/base.c 2.) IBBS / BSSID merging: We had to configure a fixed bssid, because IBBS merging fails more often than not for us. e.g: iw dev wlan0 ibss leave iw dev wlan0 ibss join "umic-mesh" 2412 E2:33:32:31:90:B3 > > Best, > > Ethan [snip full quote] Best regards, Arnd -- Dipl.-Inform.
