From the panel widget I turned wifi off because I also had an ethernet cable connected to my laptop. Later I wanted to turn wifi back on but now there is no option to enable wifi in the panel widiget nor under the network settings in the settings app. I checked: rfkill list but there is only bluetooth. Also ip link set wlan0 up doesn't work because there is now nor wlan interface. Rebooting didn't help either. How do I trun wifi back on?
Can you attach a screenshot of the panel wudget that doesn't have a switch to turn Wi-Fi back on where you expected it to be?
