Network issues over WiFi

[Android Central Question]

Hello,

I've suddenly have problems when connected to WiFi with a Galaxy S9, Android 10, Knox 3.4.1. Some apps (Firefox, Instagram, ...) can access the internet just fine and some don't (Google Play Store, Samsung software update). When I turn off WiFi and use my mobile data, ALL apps are working fine. My physical Internet connection also works fine.

I've reset my network settings, but I did not help. Do you have any idea what could be the problem?

Welcome to Android Central! Did you already try rebooting the router by unplugging its power for 30 seconds? If that doesn't help, then see this guide: http://forums.androidcentral.com/am...roubleshooting-wi-fi-connection-problems.html
