Hello, I have what may be a basic question. I am trying to use 80 MHz channels for 802.11ac and my client station reports that hostapd is always transmitting at 40 MHz. My client does report it's sending at 80 MHz though. It seems like it isn't even trying to use 80 MHz channels. There is nothing in the log about it. My card supports WiFi 6, a Qualcomm QCA6391, so it seems like that shouldn't be the limitation. I can't find any information online about why this might be. My regdomain database supports 80 MHz channels. This is what `iw reg get` shows: > global > country US: DFS-FCC > (2400 - 2483 @ 40), (N/A, 30), (N/A) > (5150 - 5250 @ 80), (N/A, 23), (N/A), AUTO-BW > (5250 - 5350 @ 80), (N/A, 23), (0 ms), DFS, AUTO-BW > (5470 - 5730 @ 160), (N/A, 23), (0 ms), DFS > (5730 - 5850 @ 80), (N/A, 30), (N/A) > (57240 - 71000 @ 2160), (N/A, 40), (N/A) > > phy#0 (self-managed) > country US: DFS-FCC > (2402 - 2472 @ 40), (6, 30), (N/A) > (5170 - 5250 @ 80), (6, 24), (N/A), AUTO-BW > (5250 - 5330 @ 80), (6, 24), (0 ms), DFS, AUTO-BW > (5490 - 5730 @ 160), (6, 24), (0 ms), DFS, AUTO-BW > (5735 - 5835 @ 80), (6, 30), (N/A), AUTO-BW > Here is my complete config: > ssid=box > hw_mode=a > channel=149 > > vht_oper_chwidth=1 > vht_oper_centr_freq_seg0_idx=155 > > wpa=2 > wpa_passphrase=xxxxxxxx > wpa_key_mgmt=WPA-PSK > wpa_pairwise=CCMP > rsn_pairwise=CCMP > > country_code=US > logger_stdout=-1 > logger_stdout_level=2 > interface=wlan0 > driver=nl80211 > > ieee80211n=1 > ht_capab=[LDPC][RX-STBC1][HT40+][SHORT-GI-20][SHORT-GI-40][DSSS_CCK-40][MAX-AMSDU-7935] > > ieee80211ac=1 > vht_capab=[RXLDPC][SHORT-GI-80][TX-STBC-2BY1][SU-BEAMFORMER][SU-BEAMFORMEE][MU-BEAMFORMEE][MAX-A-MPDU-LEN-EXP3][RX-ANTENNA-PATTERN][TX-ANTENNA-PATTERN][RX-STBC-1] > > ieee80211ax=1 > he_su_beamformer=1 > he_su_beamformee=1 > he_mu_beamformer=1 > > wmm_enabled=1 > uapsd_advertisement_enabled=1 > > wmm_ac_bk_cwmin=4 > wmm_ac_bk_cwmax=10 > wmm_ac_bk_aifs=7 > wmm_ac_bk_txop_limit=0 > wmm_ac_bk_acm=0 > wmm_ac_be_aifs=3 > wmm_ac_be_cwmin=4 > wmm_ac_be_cwmax=10 > wmm_ac_be_txop_limit=0 > wmm_ac_be_acm=0 > wmm_ac_vi_aifs=2 > wmm_ac_vi_cwmin=3 > wmm_ac_vi_cwmax=4 > wmm_ac_vi_txop_limit=94 > wmm_ac_vi_acm=0 > wmm_ac_vo_aifs=2 > wmm_ac_vo_cwmin=2 > wmm_ac_vo_cwmax=3 > wmm_ac_vo_txop_limit=47 > wmm_ac_vo_acm=0 > > tx_queue_data3_aifs=7 > tx_queue_data3_cwmin=15 > tx_queue_data3_cwmax=1023 > tx_queue_data3_burst=0 > tx_queue_data2_aifs=3 > tx_queue_data2_cwmin=15 > tx_queue_data2_cwmax=63 > tx_queue_data2_burst=0 > tx_queue_data1_aifs=1 > tx_queue_data1_cwmin=7 > tx_queue_data1_cwmax=15 > tx_queue_data1_burst=3.0 > tx_queue_data0_aifs=1 > tx_queue_data0_cwmin=3 > tx_queue_data0_cwmax=7 > tx_queue_data0_burst=1.5 > > ieee80211d=1 > ieee80211h=1 > > ap_max_inactivity=10 > utf8_ssid=1 > ctrl_interface=/run/hostapd A log of a sample session is here: https://gist.github.com/akvadrako/2fa6ab0588ff3a10c8a41b0b20ace128 If anyone has some pointers, I would be grateful. ~ dev _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
