Question "Connected and secured" but no internet access ?

Dec 19, 2017
I have integrated wifi on my motherboard. One day my wifi went out, but in a strange way - the internet is "connected and secured" but there is no internet access, e.g. chrome can't load a page. Windows troubleshooter tells me that "Windows can't communicate with the device or resource (primary dns server)", and also that "security or firewall settings might be blocking the connection".

No online solutions have solved my problem, and I have no idea what to do. Any help would be much appreciated.
