Create a Wi-Fi hotspot on Linux using nmcli

Original post : https://unix.stackexchange.com/a/310699

nmcli con add type wifi ifname wlan0 con-name Hostspot autoconnect yes ssid Hostspot
nmcli con modify Hostspot 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
nmcli con modify Hostspot wifi-sec.key-mgmt wpa-psk
nmcli con modify Hostspot wifi-sec.psk "veryveryhardpassword1234"
nmcli con up Hostspot

Note

If after reboot nmcli con up Hotspot doesn't work

Use this command instead to start Hotspot

UUID=$(grep uuid /etc/NetworkManager/system-connections/Hotspot | cut -d= -f2)
nmcli con up uuid $UUID

@CEMoreno @Blokheck011 This worked for me in when I was facing security type issue.

nmcli con modify Hotspot 802-11-wireless-security.pmf 1

Source: AskUbuntu

Error: Connection activation failed: No suitable device found for this connection (device enp12s0 not available because profile is not 
compatible with device (mismatching interface name)).

I have this error, when I try to up hotspot.

Where i ask for a non-AP mode solution... 🤝

this is wep (very weak encryptions) how using WPA3 ?

I'm also trying to use same security type (WPA3) glad to know if you succeeded for it?

Thank you all, especially abhishekmj303 for this argument (802-11-wireless-security.pmf 1)

Excellent!
In some cases, you may need:

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Let me get this, it's possible to create hotspot without being connected to a WiFi?
