My laptop windows 10 Computer Successfully Connected to wifi but when I try to browse websites it takes a very long time and nothing shows then I did network diagnose The Problem was "Your computer appears to correctly configure but the device or resource (DNS Server) is not responding ' According to diagnose then I used these steps to fix the issue you can see the CMD Command below which I used (please run CMS as Administrator )
ipconfig /flushdns
ipconfig /registerdns
netsh winsock reset
netsh int ip reset
ipconfig /renew
Please mention is this successful for you?
