How to unblock wifi internet connection after VPN uninstall?

I am using windows in my laptop. I had cyberghost VPN, it was continuously blocking my wifi today morning and disconnecting from internet. So I uninstalled the cyberghost VPN. But now my wifi still remain as connected but no internet. How can I unblock it and restore the internet?

Please help.

Check your network settings and see if there is a config file for the vpn and remove it.
Next check your DNS settings on the computer. Still not working? Your router’s firewall could have blocked you. Try logging in to your router and check see if that’s the case. A simple restart of your device could correct the issue too.

Thanks for your reply. I did run the commands written what to try first section and restarted my laptop from here https://support.cyberghostvpn.com/hc/en-us/articles/360016429900-Unable-to-connect-on-Windows- . Now I’m able to connect. Thanks for your help.

Glad you got connected!
