#deco app setup

There are various troubleshooting options you can try to fix the TpLink Deco app not working.

First things first, make sure your device is up to date with its operating system and meets the technical requirements of the app.

Next, make sure your internet connection is reliable and operational by checking it. For the Deco app to interact with your Deco mesh Wi-Fi system, there must be an active internet connection.

Try forcing a restart and force-closing the program if it's still not working. Apps may occasionally experience brief bugs that can be fixed by restarting them.

Try resetting your Deco mesh Wi-Fi system if the problem still occurs by unplugging the Deco devices, waiting a short while, and then plugging them back in.  

Refreshing the system and fixing any connectivity problems can be achieved using this.

You might want to try removing and reinstalling the Deco app if none of these solutions work. Any corrupted app files that might be the source of the issue can be fixed with this.

Try these procedures first, and if the issue still doesn't go away, you might need to get in touch with TP-Link customer care. They can offer more complex troubleshooting procedures or assist you in figuring out whether your Deco mesh Wi-Fi system is experiencing a hardware malfunction.
