I have been trying to configure my Raspberry pi 3 B+ as a 5Ghz access point but I'm unable to do so. Here is my hostapd config:
country_code=IN ieee80211d=1 ieee80211h=1 interface=wlan0 driver=nl80211 wpa=2 wpa_key_mgmt=WPA-PSK rsn_pairwise=CCMP wmm_enabled=1 ht_capab=[HT40][SHORT-GI-20][DSSS_CK-40] macaddr_acl=0 ignore_broadcast_ssid=0 auth_algs=1 hw_mode=a ieee80211n=1 require_ht=1 ieee80211ac=1 require_vht=1 vht_oper_chwidth=1 channel=36 vht_oper_centr_freq_seg0_idx=42
I get the following error
Failed to create interface mon.wlan0: -95 (Operation not supported) wlan0: interface state UNINTIALIZED->COUNTRY_UPDATE Could not set channel for kernel driver Interface initialization failed wlan0: interface state COUNTRY_UPDATE->DISABLED wlan0: AP-DISABLED hostapd_free_hapd_data: Interface wlan0 wasn't started nl80211: deinit ifname=wlan0 disabled_llb_rates=0
I also tried setting
channel=acs_survey but I keep getting the same error. How do I resolve this error?
What is the proper hostapd for configuring my raspberry pi 3 B+ as 5Ghz AP? Is it possible to utilize dual-band(2.4Ghz and 5Ghz) of the raspberry pi for an AP simultaneously?
If so, please post the hostapd for that too. Thanks in advance.
