Chromecast suddenly undiscoverable

[marie00]

Hi,

Anyone here experienced their Chromecast not being discovered by your devices?

I was playing YouTube videos yesterday. After one video finished playing, I can no longer cast anything (YouTube, Netflix, Spotify, MX Player). I have already tried resetting the device twice. The Chromecast will be successfully set up but my devices still can't find it.

Thank you.

Hi

I returned home last night, switched on tv, no chromecast. Rebooted all devices so many times. Nothing! Why won't my android phone and Chromecast find each other all of a sudden?

Hi folks,

Thanks for posting and for being a step ahead of us. I just want to clarify if your TV still displays the screensaver (ambient mode). It means the Chromecast device is still connected to Wi-Fi. I’m assuming that you’re using an older version of Chromecast (non-Google TV). The older versions can only connect to one network or bandwidth at a time. It may connect to 2.4 GHz and/or 5 GHz, but it won’t switch back and forth, unlike smartphones and other smart devices. Just ensure that the casting source (smartphone, tablet, etc.) is connected and stays on the same network or bandwidth. Instead of rebooting the Chromecast, try to toggle the Wi-Fi switch (on/off) on your smartphone. If it persists, reboot your casting source and/or your router.

Let us know how it goes.

Thanks,

Kimy

This is currently happening to me as well.  Everything was working as expected yesterday.  Now Google Chrome on my desktop can not find any devices.  I've rebooted everything several times, re-installed Chromecast devices several times, and adjusted all wifi devices to connect to 5 GHz.

Hi mlbrownewell,

Thanks for posting here. Based on your description, it was working perfectly the day prior to this happening. Have there been any changes? Did you try to isolate it by testing other devices like smartphones or other computers and not just your desktop alone? Is your desktop connected via an Ethernet connection or are you relying on Wi-Fi alone?

If you can, kindly split 2.4 GHz and 5 GHz and name them separately. Have all devices connected to 2.4 GHz and forget the 5 GHz (or vice versa) to ensure that all devices are not steering to both bands because older versions of Chromecast devices can only connect to one network or bandwidth at a time. Test and observe.

You can also isolate a possible network issue by having your Chromecast setup and connected to another smartphone’s mobile hotspot along with your own smartphone and computer.

Let us know how it goes.

Thanks,

Kimy
