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:
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
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.
