Why Devices Keep Disconnecting From Your TP-Link Range Extender

If your TP-Link extender keeps disconnecting your devices from the Internet, the cause may not be the extender itself. A range extender extends your Wi-Fi signal, but it does not maintain the Internet connection on its own. Connection stability depends on your main router and other network factors. This guide walks you through a series of tests to help identify whether the router or the extender is the root cause. The steps apply to TP-Link range extenders generally. Check your device's user guide for model-specific details.

Key Takeaways

• Devices losing Internet connection through a TP-Link range extender may be caused by issues with the main router, not the extender itself.
• Updating the range extender to the latest firmware is the recommended first step in both scenarios, as firmware updates can resolve known connectivity issues.
• Moving the range extender closer to the router during testing can help determine whether distance or signal interference is the root cause of the disconnection.
• Checking the IP address, Default Gateway, and DNS settings of the affected device at the time of disconnection can help identify whether the issue is related to IP configuration.
