Frequently Asked Questions

Why can't the TP-Link Tether app find my router?
The most common reason is your phone is connected to cellular data instead of your router's Wi-Fi network. The Tether app can only detect and manage routers when connected to the same network.
Do I need to be connected to my TP-Link router's Wi-Fi to use the Tether app?
Yes, you must be connected to your TP-Link router's Wi-Fi network for the Tether app to detect and manage the router. Remote management requires specific setup and may not be available on all models.
What if my TP-Link router's Wi-Fi network doesn't appear in my phone's list?
Check that your router is powered on and the Wi-Fi light is solid. Try moving closer to the router, restart the router by unplugging for 30 seconds, and ensure the Wi-Fi broadcast isn't disabled in router settings.
Can I use the Tether app when connected to a different Wi-Fi network?
No, the TP-Link Tether app requires you to be connected to the specific router's network you want to manage. You cannot manage your home router while connected to office or public Wi-Fi.
How do I find my TP-Link router's network name and password?
Check the label on your router for the default network name (SSID) and password. If you've changed these settings, you'll need to use the credentials you set up during initial configuration.
