Excellent thanks. :) Johannes, my previous assumption is apparently correct, The following is happening: ieee80211_open() -> ops->add_interface() -> ieee80211_start_mesh() -> ieee80211_if_config() -> ops->config_interface() -> ieee80211_hw_config() -> ops->config() Because config_interface() is called before config() the radio is not enabled at the moment config_interface() is called and the call to config() will effectively disable beaconing.
