I purchase an Apple TV model 4. Yesterday, after much difficulty, I got it to recognize the Ethernet cable and I got signed up with my Apple ID, trial ran an app successfully, etc. I left it in sleep mode. When I talked to my new internet provider yesterday they kept telling me that I should use WiFi which they would switch on for another $5/mo. They said that they much preferred working with WiFi. So this morning I signed up for WiFi and disconnected the Ethernet cable. My iMac is fine with the new WiFi network. However, when I wake up the Apple TV it goes into search mode and I just get the dashes circling around until, after about 30 minutes it reverts to the pretty picture of the bridge. At my computer I have shifted from 2G to 5G and it made no difference. When I have my TV look at the HDMI connections it recognizes that an Apple TV is hooked up. The Apple TV is only about 30 feet from the Modem. Now that I have the WiFi I would like to stick with it since I might want to try mirroring at some future date. Yesterday, when I wanted to use my Ethernet cable, Apple kept showing all of my neighbors WiFi networks (which were locked) and asking me to join one of them. How can I get the Apple TV to give me that option again so that I can connect it to my new WiFi network?
