Hello
I would like to create a wlan hotspot with this commands
nmcli con add type wifi ifname wlan0 con-name Hostspot autoconnect yes ssid xx_khadas
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 “xxxxxxxx”
nmcli con modify Hostspot ipv4.addresses 192.168.2.20/24
nmcli con modify Hostspot ipv4.gateway 192.168.2.1
nmcli con up Hostspot
After this I get a Kernel Error. Do you know what the problem could be?
