Now turn ON “flight mode” for 5 secondes and turn it OFF. This action will refresh the network connection from your device.
Once “flight mode” is off, you will see the network appearing at the top.
NB: in case no network is displayed even after several minutes, go to Network Selection on this same menu > deactivate automatic mode > select a network on the list that will be displayed after few seconds. When the network is displayed, go to the next step.
