I have a project for which I'd like to automate configuring the network settings on a Raspberry Pi. I can create a WPA1 hotspot very easily with the following bash one-liner.

nmcli connection add \
    con-name wifi_hotspot \
    ifname wlan0 \
    type wifi \
    autoconnect no \
    ipv4.method shared \
    802-11-wireless.band bg \
    802-11-wireless.mode ap \
    802-11-wireless.ssid "wifi_hotspot" \
    802-11-wireless-security.key-mgmt wpa-psk \
    802-11-wireless-security.psk "rubberbabybuggybumpers" \
    802-11-wireless.hidden yes

It seems like the NetworkManager parameter 802-11-wireless-security.key-mgmt is missing an option to specify WPA2 over WPA1.

Is there a way to create a hotspot with WPA2 encryption?

EDIT 1:

I found that specifying 802-11-wireless-security.proto rsn enables WPA2, but also leaves WPA1 enabled. How can I enable only WPA2?

    What operating system do you use? NetworkManager isn't supported by Raspbian.

  • I am using headless Raspbian Stretch. Could you possibly point me to documentation that NetworkManager isn't supported? It works great except for this one issue I'm having.

  • NetworkManager isn't part of any Raspbian image. You will not find a link that tell you what is not supported. You only will find links telling you what is supported and Raspbian uses dhcpcd: Another Raspbian Desktop User Interface Update. And no, NetworkManager isn't working great on Raspbian as you see.
