Hi, Johannes > Huh? Well that's odd, maybe there's a race condition and you program the > key before the peer was added to the device? Not so sure. The adding of key is actually done by the meshd-nl80211 (authsae) daemon running in userspace. https://github.com/cozybit/authsae/blob/master/linux/meshd-nl80211.c /* key to encrypt/decrypt unicast data AND mgmt traffic to/from this peer */ install_key(&nlcfg, peer, CIPHER_CCMP, NL80211_KEYTYPE_PAIRWISE, 0, mtk); > What device are you working with? I am using atheros 11n chipset (ath9k).
