Hi, I am trying to setup an Access point using hostapd in 802.11ac mode. The wireless interface pcie device supports 80MHz channel. I verified that with "iw list". When I configure it in 5 Ghz mode, it works fine. When I configure vht_oper_chwidth=1 and then I get the error as ACS: Failed to get compute ideal channel. ACS: Possibly channel configuration is invalid, pls report this along with your config file. Here is the hostapd.conf that I am using interface=wlan1 driver=nl80211 hw_mode=a ssid=test1234 ieee80211n=1 ht_capab=[HT40+][LDPC][SHORT- GI-20][SHORT-GI-40][TX-STBC][ RX-STBC-1] ieee80211ac=1 vht_oper_chwidth=1 vht_oper_centr_freq_seg0_idx= 42 vht_capab=[MAX-MPDU-11454][ RXLDPC][SHORT-GI-80][TX-STBC] wmm_enabled=1 wme_enabled=1 wpa=2 wpa_key_mgmt=WPA-PSK wpa_passphrase=test1234 Thanks for any help, vijaya _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
