To answer my own question: Switching off "require_ht" in hostapd configuration solves the problem. With "require_ht=1", "hostapd -d" gives the following message when using EAP authentication: -------------------- >8 -------------------- association request: STA=00:3f:8b:xx:xx:xx capab_info=0x11 listen_interval=2 seq_ctrl=0xa800 WMM IE - hexdump(len=7): 00 50 f2 02 00 01 00 Validating WMM IE: OUI 00:50:f2 OUI type 2 OUI sub-type 0 version 1 QoS info 0x0 wlan1: STA 00:3f:8b:xx:xx:xx IEEE 802.11: No supported rates element in AssocReq -------------------- >8 -------------------- The client cannot associate, and times out. Their is no "No supported rates element in AssocReq" with "require_ht=0" and everything works. HT is still available after association. This is 100% reproducible with ath9k and rt2800usb APs. Could HostAP developers please tell me if this is expected, or should I report a bug?
