Expected Behaviour:
Wireless network able to work with pihole set as the dns.
Actual Behaviour:
when the dns is set, only wireless devices lose internet connection. I first discovered this when I was setting the dns in my tp link xe75 pro. To confirm this I tested the pihole dns for individual devices like my phone and got the same result.
