Let’s dive into it!
Kasa Switch Not Working: How to Troubleshoot
1. Check the Wi-Fi Connectivity
At some point, you may notice that your Kasa Smart Switch keeps losing Wi-Fi connection, making it difficult to operate the device via voice commands or app prompts.
If this is the case with your TP-LINK Kasa Switch, the first thing to do is confirm your device’s connection status. The switch has a LED indicator to track Wi-Fi network connectivity. If the indicator blinks green, your device is connected. A yellow or red blinking light is a sign that your Kasa Smart Switch has lost Wi-Fi connectivity.
Your Kasa Smart Switch may develop connection issues for any of the following reasons:
- The switch is out of range.
- Physical obstructions and electronic interference from other devices.
- The router is malfunctioning.
- There are too many devices connected to the Wi-Fi channel.
- The switch is connected to an unsupported Wi-Fi band (5GHz).
- The switch is malfunctioning.
You can start troubleshooting this issue by moving the Smart Switch within range. Ideally, your Kasa Smart Switch should be within 150 feet, or less, of your Wi-Fi router or access point. Otherwise, you need to invest in a Wi-Fi extender to boost the signal.
If your smart switch still cannot connect to the Wi-Fi network, check around for objects that may interfere with signals, such as:
- Physical barriers (concrete or timber walls).
- Small electronic devices (garage openers, baby monitors, radios, etc.).
- Household appliances (microwave ovens and television sets).
Switching to another Wi-Fi network, separate from the channel you use regularly, can help fix the issue. Overloading a single Wi-Fi channel with devices often leads to a malfunction, which could be the reason your switch cannot connect.
A popular fix for Kasa Smart Switch Wi-Fi connection issues is rebooting the router and the switch. That’s often the last resort for users, and you should try it only after exhausting other options.
You should also note that connecting your smart switch to the wrong Wi-Fi band is another lesser-known cause of connection issues. Since the Kasa Smart Switch supports 2.4GHz by default, connecting it to a 5.0GHz network is likely to affect connectivity.
If your router has a dual-band, be sure to set it to run only on the 2.4GHz Wi-Fi band. You can do this via your router’s Wi-Fi settings or by selecting the 2.4GHz.
2. Inspect the Wiring
Wiring issues are an oft-cited cause of malfunctioning in TP-Link smart switches. The switch may be simple to install, but you can still make mistakes—especially if you’re not a pro. Here is a list of wiring issues that may be responsible for the problem:
- You connected the wrong wire.
- The wires are out of position.
- The device has short-circuited.
Except you have the expertise, it’s best to have a qualified electrician assess the problem and recommend solutions. If you decide to install the switch, keep the following things in mind:
When installing the switch, pay attention to the colors on the wires. Live, neutral, and ground wires have different colors to prevent installation mistakes.
Use the wire caps that come with the switch to safeguard wired connections
Avoid setting up the switch system if you don’t have experience installing electrical devices
3. Reset the Smart Switch
It’s not uncommon to have software glitches affect the functioning of Kasa Smart Switches. Like any high-tech device, the TP-Link HS200 Smart Switch will perform poorly if the code isn’t working.
A device reset clears pre-programmed settings and eliminates the glitch, which is why it’s a common DIY fix. You can either perform a hard reset or soft reset on your TP-Link device.
A hard reset restores the device to its original state when you first bought it—any pre-saved configurations will disappear. Also called a factory reset, this can be effective if a soft reset cannot work.
A soft reset wipes your device’s current operating system but safeguards your saved settings and configurations. If setting up your smart switch anew sounds like work, this may be your best option for fixing the problem.
- Performing a soft reset: Performing a soft reset on your Kasa Smart Switch requires pressing and holding the reset button for five seconds. Then you have to check for a green light to confirm if the app configuration has started.
- Performing a hard reset: Hold the RESET button for about 10 seconds until the amber indicator flashes to perform a hard reset. That should wipe off every memory from the app and activate factory default settings.
