For example this is how my config looks like ``` allow-hotplug wlx000f00bf4a3f iface wlx000f00bf4a3f inet static address 192.168.1.71 netmask 255.255.255.0 gateway 192.168.1.254 wpa-ssid ssid-name wpa-psk e8918bce6980814557b664fb52bda4d342174d2a2c95dd06078d7a29851de799 ``` Hope this helps. -- Regards, Nektarios Katakis
