I'm having issues to connect. And why do I need to connect to a 2.4GHz network?

In order to successfully connect Atomi Smart devices, a 2.4GHz connection is required.

The 2.4GHz frequency waves travel further than the 5GHz. This means that if your device is in another room or far from your phone, you will have a better signal reception (compared to 5Ghz) which is essential for your smart device to function correctly and stay online.

All modern routers come with 2.4GHz and 5GHz. Depending on your router type, these bands may appear as separate WiFi networks (Example: Name-2.4GHz and Name-5GHz) or combined. If you only have one WiFi network, you should still be able to connect since the Atomi Smart app automatically finds the 2.4GHz frequency when connecting to your router.

However, if you experience any issues, please follow the points below:

– Make sure that you are connecting to a 2.4GHz network

– Keep your mobile device close to the router during connection

– If you have two SSID for your WiFi (Example: Name-2.4GHz / Name-5GHz), please temporarily disable “Auto-Join” on your Name-5GHz network)

– If you have two SSID for your WiFi, make sure that your 2.4GHz and 5GHz WiFi have different names

– If your router gives the option to disable the 5GHz network, please disable it temporarily

– Disable any VPN apps/services in order to connect successfully

– If you are having issues to connect, turn on Airplane Mode (Keep only WiFi activated when connecting your smart device)

– Make sure that you’ve entered the correct password for your 2.4GHz WiFi on the “Select 2.4GHz Wi-Fi Network” screen (Case sensitive, and make sure that there are no extra spaces)

– If you have too many devices connected to your 2.4GHz (more than 10), please turn off some of them temporarily and retry connecting your smart device to the app

– If you have a Mesh router, you may not be able to manually switch to a 2.4GHz frequency. Since this frequency travels further than the 5GHz, you can force your device to connect to it by moving your phone far from the router

– If you are still experiencing issues to connect, delete the app and reinstall it

– If the issue persists, restart your router

I can’t find the atomi-smart-XXXX network in my Wi-Fi list
