I received a Chromecast for Christmas and am having some difficulties setting it up. My internet provider is CenturyLink and my router is an Actiontec M1000. When I attempt to set up to Chromecast, My computer says “Something went wrong. We weren’t able to find your Chromecast on the network. I had already entered the network ID and Password. After this, the popup suggests 3 trouble shooting solutions: 1) Ensure you are not connected to a VPN (I’m Not) 2) If you have a dual band (2.4 and 5GHz) router – ensure it is not in AP isolation mode (I don’t know what this means) 3) If your router has MAC whitelisting – your Wi-Fi network allows this device and your Chromecast to join (not sure here either)
It then prompts me to visit this support page: https://support.google.com/chromecast/#topic=3447927
When I go to Chromecast Router Compatibility and find my Actiontec M1000 router, I click on the workaround option to try and find a solution to the problem. it says that if multicast is available I need to enable it by going to my Router settings > Enable UPnP. I cannot find this option in my router settings so I am not sure if it available for my router, or even if my router is compatible with Chromecast at all.
Any help at all would be much appreciated!
