Wifi connectivity issue only with Huawei router
I have purchased new IPhone 8 Plus, it is connecting to all WiFi devices except my home device (Huawei router) model HG659.
I cannot understand why because all mobiles are connecting with my Huawei router except my Iphone 8 Plus. Even my wife also bought new Iphone 8 plus and surprisingly her IPhone is connecting with the same WiFi router. I have tried all things from restarting my Iphone and router and even tried reset network settings. I have tried it before updation and after updation to IOS 11.3 but the result was same, I could not connect my Iphone to my home WiFi router.
