I worked hard to make the device starlit finally did.
I don’t understand that. starlit?
but when I go to the Network settings.... wifi never works.. only Ethernet.
If anything is plugged into the ethernet port, then Wi-Fi is not available at that time, only ethernet. That is an intended feature of Apple TV. To use Wi-Fi, simply unplug the ethernet cable from the Apple TV device.
Please check the screenshots. What do you think?
DNS should not be the router itself. That is a faulty setting right there. If Auto doesn’t work, then use IP addresses of actual DNS servers. There are some public/open DNS servers, if you can’t find the recommended DNS server addresses from your ISP. Each ISP will have their own DNS servers, which should always be the fastest option for you. The DNS settings should always list two DNS servers.
As you are using manual settings, I can’t see from the settings if there is a conflict or other issue of communication between the router and the device. As stated earlier, manual settings are not recommended, nor ever needed (unless your corporate network admin tells you to do so, which doesn’t apply in home situations).
You would need to verify any manual settings with what the router detects as devices on your home network – which is why Auto is so much easier.
