Huawei WiFi Issues

<p>I've had my Huawei P8 for about 7/8 months now and everything has been going well. Last month my phone didnt want to pick up WiFi signals. I tried rebooting and all sorts of things until I gave up. One day I just saw the phone working again. All was fine until last week. Once again the phone didnt want to pick up Wifi, it keeps saying "Denied Access to network". I have done all the rebooting procedures but my phone still doesnt want to pick up any Wifi signal. What do I do now ?</p>
