Huawei P8 lite 2018 why I can't connect to ethernet without my router

[Eitzberg]

Until recently I only used my router to Google and WhatsApp. My provider has now enabled data transfer so that I can do the above away from home. But it doesn't work. My Smartphone language is German and I have the following setups:-

Einstellung -
Drahtlos & Netzwerke -
Mobile Daten (17. Tag 0.00B) -
NetwerkApps:
u. a. WhatsApp und Google+ (beide Mobile und WLAN aktiviert)
Datenverbrauchsoptimierung:
Installierte-Apps:
u. a. WhatsApp & Google+ aktiviert
System-Apps:
u. a. Google aktiviert

Can anybody help me or should I change the language to English for help? My wife has a P8 lite 2017 and it works.

Welcome to Android Central! I'm sorry, I don't quite understand what you're asking. What do you mean when you say you only used your router to Google and WhatsApp? Do you mean that when you connected your phone to your home wi-fi network, all you used it for was to use the Google app and WhatsApp? Even if you're not using other apps, they're still accessing the web intermittently to refresh data.

What do you mean that your provider has enabled data transfer? Do you mean that you now have 3G/4G mobile data?

By the way, this is what Google Translate says:
