Why does my mobile phone no longer connect to the WLAN?

Since I came out of school yesterday, my cellphone does not connect to the WLAN anymore, unless I'm standing next to the router.

But my star both have wlan throughout the house and I can't connect with any Wi-Fi (so not synonymous with our neighbors or so).

I've already tried everything, made mobile out, made route out, made wireless from, flight mode on, free up space, logged out of the Wi-Fi and yes.

Does anyone know what it could be?

(It's a huawei if that's important)

Think about it in advance

I know that as well. I always do a restart on the phone and then it works again.

Restart the router or check the settings on the phone.
