Sometimes Chromecast is not found. 0 Recommended Answers 1 Reply 6 Upvotes

I have 2 chromecast (gen 2) and a Home Hub casting from android. Up until about a week ago, never had an issue casting to any of them.  Now sometimes they show up, sometimes I have no devices available, sometimes one or two of them is in the list.

Tried rebooting devices, wifi and android phone. Sometimes that works, sometimes not. Google Home devices don't seem to have any issue sending content to chromecast, just the phone. Was there an update that is messing up device discovery? How do you fix this?

Hello, Welcome to the Chromecast user help community.
Try each of the following before moving on to the next:
  • Is your Android device on current Minimum system requirement?
  • Do you have the Google Home app  installed that replaced the Chromecast app?
  • Make sure you power the Chromecast device with the provided power supply into an open electrical outlet, not using a USB input on your TV or other device.
  • Check your Android Wifi settings using this Nexus Help page.
  • Your Android device and Chromecast device should be within ~15 feet (4 meters) of each other. Your Chromecast device should be ~15 feet (4 meters) away from your router, or less.
  • Unplug your Router and Chromecast from electrical wall outlets for 5 minutes, and turn your Android device OFF/ON
  • See original post by Google employee about other settings.
  • Try Chromecast on the SAME 2.4 (Chromecast 1st gen requirement) Ghz frequency wifi router band as your Android devices
IF NO RESOLVE after trying steps above.
Conduct a Factory Data Reset
Make sure your Chromecast device is powered aat a wall outlet with the supplied power adapter
Next, re-setup your device
