Chromcast disconnects to Wi-Fi randomly

Bryanew40 — Wed, 06 May 2026 14:03:16 GMT

My chromecast 3rd gen 10395a-G454v frequently disconnects and reconnects from the Wi-Fi. I have another chromecast downstairs that is further away from the Wi-Fi router that connects and works with no random loss of connection. I have high speed internet connection so that also should not be at fault. I do the classic of replug and unplug the dysfunctional chromecast, reconnect and disconnect from Wi-Fi, signing in and out but it still randomly lags and disconnects from the Wi-Fi. I tried chromecast support and received no help beyond the class IT suggestions of unplug and replug. I am really frustrated because this chromecast is closer to the Wi-Fi router than the other functioning one. Please suggest fixes or send a replacement

A patchy wifi connection can sometimes mean a congested wifi channel / frequency. Try changing the wifi channel in your router / hub uses. Download a "wifi analyser" from your favourite app store which should be able to tell you which channels are congested and which are not.

Hi @Bryanew40,

Thank you very much for reaching out to the community! I understand the issue you are having with your Chromecast constantly disconnecting from your Wi-Fi. I appreciate you contacting support to confirm the troubleshooting steps you have already performed and for noting that your other Chromecast is working properly. I realize how frustrating it is when a device does not perform as expected; please rest assured, I am here to help.

I would like to share some troubleshooting steps that may resolve the issue:

Power Source Verification:
- Please verify that your device is connected directly to a wall outlet using the original Google power adapter (brick).
Turn on Bluetooth and local network access only if you have iOS device:
- Go to your iOS device's Settings app.
- Select Bluetooth and make sure it’s enabled.
- Go back to Settings.
- Tap Privacy and security > Local network.
- Turn on Local network for Google Home.
Router Configuration Check:
- Check AP: Ensure that "AP Isolation" or "Guest Mode" is disabled in your router settings. This prevents the phone from being able to "see" the Chromecast.
Perform a factory reset on your Chromecast or Google TV Streamer.

@mildenhall, thank you very much for your recommendations regarding this issue!

Please feel free to share any additional details you think might be relevant.

Best regards,
Eduardo
