Fix “Phone or Apps unable to find Chromecast device on same WiFi network”

The issue being discussed here can be caused by a variety of issues. Therefore, it is not possible to pinpoint on to just one. Below is the list of all possible bugs and fixes for when phone or apps cannot connect to or find Chromecast device on network.

Make sure to check the easiest methods first and then move on to more advanced solutions.

Restart Router and Chromecast Device

Restarting is the most common troubleshooting method that works for over 90% of problems. And this is not just a coincidence. Both and old modern devices can get worn out if they run for a long time. Or they just did not set up correctly. Therefore, just restarting can fix the most basic issues.

Do this in following order:

  1. Switch off router.
  2. Unplug Chromecast device.
  3. Turn on router and wait for its WiFi to be active.
  4. Plug in Chromecast device again.
  5. You may also restart your phone just to be sure.

Now just check your apps and see if casting is working now. Otherwise, move on to next step.

Check Network

It is possible that the network for Chromecast device and your phone is actually different. It can happen due to number of reasons. Maybe one of these two got connected to a different router and you did not realize.

Another possible culprit is Smart Network Switch. This is a modern option now available in almost all Android smartphones. This feature allow users to constantly switch between WiFi and Mobile data. The switch happens when one of the networks is weak. The switching in network can disconnect you from Chromecast.

For those who report that their phone disconnects from Chromecast after few minutes, this may just be the answer. In order to fix this, either just turn it off and use normal switching or add casting apps to filtered apps.  Smart Network Switch option is available under WiFi tab in settings. However, this filtering is not always available or very successful, therefore, just turn smart network switch off.

Try using Chromecast after this. If it is not fixed, lets move on to next step.

Factory Reset Chromecast

Not so long ago, Google released a software update for Chromecast devices. It also warned the users that it may break it! It may have stopped working just like so many users have reported it. The mentioned solution for this is to factory reset it. The factory reset method for Chromecast 1st Gen and 2nd Gen is same. Follow these steps:

  1. Plug in Chromecast device to a USB Power outlet.
  2. Locate a button near its USB port.
  3. Keep it pressed for few seconds until the light turns white.
  4. Once it is white, let the button go.
  5. Your Chromecast device is now factory reset!

From here on, use the usual method to set up your Chromecast device using Google Home app.

Check if Battery Saver is messing with Chromecast

Chromecast may disconnect from your phone if the battery saving services in phone cut the connection. How does it work? Well, most modern devices have built-in battery saver apps to maximize battery life. The monitor all apps for background usage. When the usage is extended for long time in background, they cut it off to save battery. The app thinks that it is not in use and just consuming battery.

What actually happens is that Chromecast although does not use phone to cast but it required persistent connection. Otherwise, users may encounter issues like Chromecast controls do not work after sometime on phone. This issue in particular is caused by battery saving apps.

Check WiFi bands (2.4Ghz or 5GHz) and Channels

First generation Chromecast devices connect with older 2.4GHz WiFi connections. However, the second generation supports even 5GHz. While it is faster and good, it could still cause some bugs.

The Chromecast may stop showing up on phone after some time if the WiFi connection is messed up. Therefore, try switching the WiFi connections for it. To do so, follow these steps:

  1. Reset the Chromecast as shown above.
  2. When connecting it to WiFi again, select 2.4GHz if it was previously connected to 5GHz (2nd Gen models). 1st Gen models only connect to 2.4GHz though. You can see the 5G sign on WiFi SSID while connecting. The 2.4GHz channel only shows WiFi name.
  3. Now try casting from your device.

If it does not work, then change channel for 2.4GHz to 11 from router settings page. This option is available under Wireless settings. Below is an example but this interface is different for all routers. Also note that, some routers may not have channel 11 as an option. Try other channels in this case.
