I have been trying a few different things to get hostapd working with my wireless card. With ieee80211d/h off ACS attempts to use channel 149 (80 MHz wide) and prints out a message of "Could not set channel for kernel driver”. When I turn ieee80211d/h on the message I get is "Can't set freq params” and "DFS start_dfs_cac() failed, -1”. The DFS stuff seems to want to use channel 52. According to iw list both 52 and 149 are supported channels by my hardware. I am using the ath10k driver with a Airetos AEX-QCA9880-NX wireless card. The full testing configuration I am attempting to use is below. Is there anything I am completely wrong on or could there be driver/firmware/hardware issues? interface=lan-wireless driver=nl80211 ssid=test hw_mode=a channel=0 ieee80211n=1 ieee80211ac=1 ieee80211d=0 ieee80211h=0 country_code=US vht_oper_chwidth=1 vht_oper_centr_freq_seg0_idx=42 vht_oper_centr_freq_seg1_idx=159 -- Matt Keeler _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
