Tether App, which is available in iOS and Android only, is the place where you can manually set up your TP Link Router IP. Make sure you downloaded the app before moving onto the next part. Another thing to bear in mind is to check whether your router is compatible with Tether.
Go to your smartphone’s Wi-Fi section and connect to your router’s wireless network which is shown in the below image.
Launch the app Tether
In the Local Devices section, tap on your router icon. In most cases, it will be the only shown router.
You will be asked to log in with your router’s credentials or change your password.
You will be redirected to Quick Setup. Select your Internet Connection Type and hit the “Next” button.
You can change the Network Name and Password of your router in this section if needed, or else tap “Next.”
Review everything again and click “Save” to get the configuration started.
Wait a couple of minutes and hit “Finished” to complete the process.
