Sengled Bulb Keeps Disconnecting: Try These Troubleshooting Tips

1. Update the Sengled App on your Phone/Tablet

As mentioned earlier, your Sengled light bulb may keep disconnecting because you’re using an outdated version of the app.

As you probably know, old app versions may contain bugs/ errors, and these errors are usually fixed in the new versions. So, if your Sengled bulb keeps losing connection, check and update the app to see if it resolves the problem.

Follow these steps to update the Sengled app:

Go to the Google Play Store on your phone. If you use an iPhone, go to the App Store.
Enter “Sengled” in the search bar.
Click on the Sengled app in the search results.
If your current Sengled app version is outdated, you will see the Update button at the top of the screen. Tap the button to install the latest version of the Sengled app.

2. Move Your Router Closer to Your Sengled Bulb

Weak Wi-Fi signals can also cause your Sengled bulb to keep losing connection. And this usually happens if the router is located too far from the bulb.

To fix this issue, bring your router closer to the bulb. We recommend placing the router less than 30 feet away from the Sengled bulb.

3. Reboot Your Router

If your Sengled smart bulb still keeps disconnecting after bringing the router closer, you may need to reboot your router.

Here’s how to reboot your router:

Press the power button on the router to turn it off. If your router is plugged into a power outlet, remove the plug from the outlet.
Wait for about 30 seconds.
Now, turn the router back on and plug it back in. Your router will restart.

4. Change Your Wi-Fi Band 2.4GHz

Another likely cause of connectivity issues with your Sengled light bulb is an unsupported Wi-Fi band. That is, your router may change the Wi-Fi band automatically, and the bulb will lose connection when the router switches to the 5GHz band.

As you probably know, most routers are dual-bands. This means they can offer Wi-Fi networks on both 2.4GHz and 5GHz bands. Occasionally, your router may switch from one Wi-Fi band to another, depending on the network with the strongest signal.

However, the Sengled bulb is only compatible with the 2.4GHz network. So, when your router connects to a 5GHz network, your Sengled bulb may disconnect.

You can fix this issue by setting your router to run on the 2.4GHz band only. Refer to your router’s manual to learn how to do this.

5. Update Your Sengled Bulb Firmware

Your Sengled bulb may keep disconnecting from your Wi-Fi because the bulb’s firmware version is outdated.

Although Sengled bulbs update their firmware automatically, the update may sometimes fail due to an error. So, you’ll need to check and update your bulb’s firmware manually.

Follow these steps to update your Sengled bulb’s firmware:

Open the Sengled app on your phone/tablet.
Click on the Settings tab at the bottom of the page. Then tap Firmware Update. If any of your Sengled devices need firmware updates, the Firmware Update option will have a red dot beside it. If you see this red dot, tap the Firmware Update tab.
Now, click on the Upgrade button beside your Sengled bulb to update the firmware.

Your Sengled bulb should stay online after updating its firmware.

6. Reset Your Sengled Bulb

If the bulb keeps disconnecting after trying all the tips here, try resetting the bulb.

Here’s how to reset your Sengled Bulb:

Turn on the bulb via the wall switch.
Quickly turn the switch off and on five times. If you do this correctly, your Sengled bulb should flash three times. After this, it will blink twice to show that the reset was successful.

But if the bulb doesn’t flash, you’ll need to repeat the process.

After a successful reset, your Sengled bulb will activate pairing mode. This means you can now connect it to the Sengled app. Turn the bulb off to keep it in pairing mode. You’ll turn it back on when the Sengled app tells you to do so.

Note that resetting your Sengled Bulb will restore the factory settings and delete all custom settings. So, you’ll need to re-add your Sengled Bulb to the Sengled app.

Follow these steps to re-add your Sengled Bulb to the Sengled app:

Ensure that the bulb is turned off and that your phone is connected to a 2.4GHz Wi-Fi network.
Open your Sengled app and tap the Menu icon (3 dots) at the top of the home screen.
Next, click on Add Device and select Wi-Fi LEDs and Accessories.
Click on Confirm to continue.
Turn on your Sengled bulb. Your bulb should flash, indicating it is still in pairing mode.
Tap Search Devices. The Sengled app will now start searching for the bulb.
When the Sengled app finds your bulb, it will appear in the app.
Now, click on the Connect button beside your Sengled bulb to set up the device in the app.
Your phone will connect to the Sengled Bulb’s Wi-Fi. It will then send you to the “Select a Wi-Fi Network to Connect” page.
A list of all your router’s 2.4GHz Wi-Fi networks will be displayed. Choose the network with the strongest signal.
The system will ask you to input the Wi-Fi password. While entering the Wi-Fi password, tap on the Show icon to ensure that you are typing in the correct password.
After entering your Wi-Fi password, click on Next.
Your Sengled app will now try setting up the bulb. If the setup process is successful, the bulb will flash within the first 30 seconds of the process.

After the setup, you’ll be sent to the Congratulations page. This means the re-adding process was successful. Click on the room where your Sengled bulb is placed, and assign the bulb to the room.
