I was ALWAYS able to ALWAYS connect to the laptop (Acer VN7 Nitro) with the hotspot of my mobile phone (Huawei P9 Lite).

About a week ago, the network transmission did not work (connection was limited on the laptop). Then I pressed on the laptop at my hotspot on "Network not save", so that the connection works again (I have already done several times).

Now the problem is that I can no longer connect to the hotspot. After entering the password, it loads briefly and then "No connection to the network is possible". I tried everything - WLAN adapter on the laptop uninstalled and reinstalled, laptop and phone restarted, software update made on the phone, hotspot password removed, … No attempt to connect me was successful.
