My Access Point isn't working, could I get some help?

Question

I went through a tutorial on thepi.io. However, my AP isn't showing up or not working. I ran the:

    sudo hostapd /etc/hostapd/hostapd.conf 

then it came back as:

    failed to create interface mon.wlan0: -95 (operation no supported)

    rfkill: WLAN soft blocked

    wlan0: could not connect to kernel driver 

    Using interface...

    Failed to set beacon parameters

    wlan0: could not connect to kernal driver

    Interface initialization failed 

    wlan0: interface state UNINITIALIZED->DISABLED

    wlan0: AP-DISABLED 

    wlan0: Unable to setup interface.

    wlan0: interface state DISABLED->DISABLED
    wlan0: AP-DISABLED 

    hostapd_free_hapd_date: Interface wlan0 wasn't started 

    nl80211: deinit ifname=wlan0 disabled_11b_rates=0

I apologize for the formatting errors if there are any, I could really use some help.

Answer 1

The first message failed to create interface mon.wlan0: -95 (operation no supported) doesn't matter. Monitor mode isn't supported by the on-board WiFi device. The kernel only tells you this.

But the second message is important:

rfkill: WLAN soft blocked

All other messages are follow up messages. I don't know why, because by default the device isn't soft blocked. You have to unblock it with:

rpi ~$ sudo rfkill unblock wlan

Show status with:

rpi ~$ sudo rfkill list

If Wireless LAN is Soft blocked: no then hostapd should start.

If you don't have rfkill installed, just install it with:

rpi ~$ sudo apt install rfkill
