Running ifconfig -v wlan1 makes: sturbo ucast NONE mgmt 6 Mb/s mcast 6 Mb/s maxretry 6 11na ucast NONE mgmt 12 MCS mcast 12 MCS maxretry 6 11ng ucast NONE mgmt 2 MCS mcast 2 MCS maxretry 6 I think that it's incorrect. 12MCS needs 2 spatial stream and what is with cards which support only one? Something in this subject is mentioned in line 1608 sys/net80211/ieee80211.c 1608 >.......>......./* NB: 12 is ambiguous, it will be treated as an MCS */
