After updating Ubuntu, my wifi is not working.
Issues faced:
1. From top right corner menu, "Wifi off" is shown. And when i trey to turn it on, noting happens.
2. If i go to Wifi settings and turn on using the top orange colour button (which was off previously and was grey in colour. ), colour changes but it still says wifi is off.
3. After closing and opening this dialog again, then it shows ON button.
4. But below that is says "No wifi adaptor found. make sure you have wifi adaptor plugged and turned on".
