I found a simple solution and it worked. Switch off your Huawei device. Press both the volume down and the power button at once until the Huawei or Android logo comes up, then choose 'WIPE CACHE PARTITION' Reboot your phone. Wipe the cache partition again. Reboot your phone. Find the FM Player app on your device. Connect a headphone to your device (which is used as an antennae) Play FM for a couple of seconds. Remove the headphone and turn on your WIFI. It worked for me and I am sure it will for you!!! @coolchasere
