      The Raspberry Pi 4 Model B is finally here, a $35 device that packs a lot of useful technology on a single circuit board you can hold in your hand. It might even be your next budget computer, assuming you can stomach some of the trade-offs enthusiasts have identified in their early testing.

      This tiny tool that powers plenty of people’s clever hacking projects—including dorm room parties—gets a lot of great upgrades for its fourth-generation release. On paper, the specs are impressive: a 1.5 GHz, quad-core, ARM Cortex-A72 processor; up to 4GB of memory (bumping the price to $55); Gigabit Ethernet; wireless-ac; and the ability to push 60 frames per second to a 4K display (or 30 frames per second to two connected 4K displays).

      • @rafitc99 said in NMCLI AP Mode config error | Connection activation failed: No suitable device found for this connection | Raspberry Pi 3 Model B Rev 1.2:

        sudo nmcli radio wifi on
        sudo nmcli con up $host

        Hi @rafitc99, Are you able to set up the AP when trying the commands individually?

      • I was trying to configure AP mode in Raspberrypi by using Network Manager. I'm using the below script. but it is throwing some errors.

        Bash Script to set AP Mode

        host="MyRPiAPMode" sudo nmcli con add type wifi ifname wlan0 con-name $host autoconnect yes ssid $host sudo nmcli con modify $host 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared sudo nmcli con modify $host wifi-sec.key-mgmt wpa-psk sudo nmcli con modify $host wifi-sec.psk "SomeRandomPassword" sudo nmcli radio wifi on sudo nmcli con up $host

        Error ----

        nmcli con (After script execution)

        I tried to make it availble via sudo nmcli radio wifi on
        But not working.
