Huawei p8 isn't connecting to wifi

[Anna.E]

I have a Huawei P8 and past week it fails to connect to my wifi, even when I am in the room where my broadband box is, it's a very poor connection. other family members are connected just fine, and my iPad also connects just fine, even in my bedroom, it has good strength. 

I went onto support thing here where you select, personal, pay monthly then your Mobile model... But they don't have mine on there! Not helpful. So thought I would try on here, unsure if it is my phone but as other devices work in my wifi I can't see what else it could be.

Hi there

If other devices work fine it would indicate that it is the P8 that isn't working properly.  Have you tried connecting it to another WiFi network, and if so, did it work okay?

Hi. Other things to try are turning off then back on, forget WiFi network then reconnect, factory reset if the phone (having backed important stuff up).

If none of these or @drey_p suggestions work it may need to go for repair.
