VPN is off.
the wifi network i set up is named 'WASTELAND'. i see that 'WASTELAND 2' is blocked.

Thank you for providing the information, Joe.
May I know whether you've installed VPN program? If yes, then kindly disable VPN then enable Firewall and check the issue.
Also may I confirm whether the firewall is set to "I trust this network"? 
Thank you and keep us updated.
