Kasa Smart Bulb is a successful product produced by TP-Link, it has sold thousands on Amazon due to its features such as long lifespan, remote control, ability to create scenes and schedules, reduction in power consumption, as well as the ability to change color and adjust brightness, and many others.
People who use these bulbs on their property say that sometimes they lose the wifi connection and wonder why and what is the solution to get them back online?
Kasa bulbs can lose internet connection due to many causes such as weak Wi-Fi signals, wall switch off, firmware and hardware issues, router failure, interference problems or expired internet connection.
How do I troubleshoot Kasa smart bulbs not connecting to Wifi?
So users are looking for a solution to this problem and this is what I am going to show you in the next chapters of this article, all tips that I am going to provide are easy to understand and implement and you can do it yourself even if you’re not a techie.
One: Check the wall switch.
The first thing you need to do is make sure the light switch is on because when you use a traditional light switch with a smart bulb and it’s off, your lamp will lose its Wifi connection.
Two: Check your Internet subscription.
The presence of your internet connection is a must for your Kasa smart bulb in order to work and connect to your mobile and voice assistant.
And when your internet subscription expires, the bulb will experience connection difficulties, so make sure your subscription hasn’t expired yet and if it has, renew it to fix this problem.
Three: Power cycle your router & modem.
To get the most out of your internet connection you should periodically reboot your modem & router, a reboot can fix certain internet connectivity issues, from no internet connectivity to slow wireless connections.
This process also allows them to reset and re-establish a connection to your ISP and help the router and modem recover from an unresponsive state and let them re-select the least crowded channel for each frequency and provide a stable connection to your Kasa bulbs.
Four: Check for firmware updates.
Firmware refers to a type of software that has been permanently installed and programmed into a special memory contained in your Kasa Smart Bulb.
This firmware is frequently updated by the manufacturer to fix bugs and performance issues, including connectivity issues, as well as to improve device functionality, so go to the app and check if there’s a new update, here’s how to do it:
- Open the Kasa app and log in to your account.
- Tap on the hamburger menu at the top left corner of the screen.
- Then click on Settings.
- select Firmware Update.
- If any firmware updates are available, they will be displayed on this screen.
- If there is a new firmware version, please click the corresponding firmware and the Kasa bulb will be updated automatically.
- Don’t use the bulb until the firmware update is finished.
Note: Updating your Kasa app and your router firmware is as important as updating the Kasa bulb, so make sure you do that too.
Five: Connect to 2.4 GHz frequency.
Kasa bulbs only work on the 2.4 GHz frequency, which has many advantages such as a wider range and can penetrate solid objects better, as well as greater compatibility with many smart home devices that work on this channel.
So ensure that you’re enabling the right frequency on your router when connecting your bulb to the internet, and avoid enabling both channels at the same time if you own a dual-band router.
Six: Reduce interference and expand signals.
Wifi interference could be the root cause of your Kasa bulb connectivity issues, it can lead to slower speeds, higher latency, frequent disconnects and reconnects, and sometimes a complete inability to connect to a Wi-Fi signal.
You can fix this interference problem by relocating your router away from nearby routers, appliances and dense building materials, unplugging the devices when not in use, and avoiding using too many wireless gadgets at the same time within close proximity of each other.
Weak wifi signals are also a cause that leads your Kasa smart bulbs to connectivity issues and this problem mainly occurs when your router is so far from your lamp.
If your bulb is installed in a dead zone, there are many ways to boost your Wifi signals and let them reach all your devices, such as moving your existing router to a better position, installing a mesh Wifi kit, or a Wifi extender, buy a new router with better performance.
Seven: Reset the Kasa Smart Bulb.
Resetting your light bulb can also fix connectivity issues and can be a solution to any issues you are facing, but make sure to leave it as your last solution as it can delete all settings and user data from the app.
Note: a soft reset that does not erase the current settings, and a factory reset that erases all of your custom settings and restores them to factory defaults.
To reset your bulb you need to turn the light switch controlling the bulb to the OFF position, then flip the light switch on and off 3 times, 5 times, or 10 times depending on the model you have.
Follow the instructions shown in this article to reset your bulb correctly.
Eight: Reset your router & modem.
The last solution in this article is to reset your router and modem, this will restore them to factory default settings and can fix connectivity issues and improve speed and signals while maintaining a reliable internet connection at all times.
Reset the modem:
- Ensure that your router is on.
- Use a paperclip and hold down the reset button for 30 seconds.
- Release the button and wait for the router to power back on.
Reset the router:
- Turn on the modem.
- Press and hold the reset button with a paperclip.
- Release the button when the modem lights start to flicker.
- Wait for the internet light to turn green.
