Check your network

How can I ensure that the TV and Mac are connected same network?

Start IP

End IP

For example, if the IP address of the phone is 192.168.0.3, and subnet mask is 255.255.255.0, IP range calculator will return Start IP is 192.168.0.1, End IP is 192.168.0.254.

The IP address of the TV is 192.168.0.4 in between the range, and subnet mask is same, so it's same network.
