Here’s a step-by-step guide:

1. Placement of the Repeater: First, find a suitable location for your WiFi repeater. It should be about halfway between your router and the area where you need better WiFi coverage. Make sure it’s within the range of your existing router’s WiFi signal.
2. Power On: Plug the repeater into a power outlet. Wait for it to start up. This might take a few minutes. You’ll typically see some LED lights come on.
3. Connect to the Repeater’s Network: On your computer or smartphone, scan for available WiFi networks. You should see a new network, often with the name of the repeater’s brand or model. Connect to this network. Initially, there might not be a password, or it may be something simple like ‘admin’ (check your repeater’s manual for default credentials).
4. Access the Repeater’s Setup Page: Open a web browser and enter the repeater’s IP address, which is typically printed on the back of the device or in the manual. If not, common addresses are 192.168.0.1 , 192.168.188.1 or 192.168.1.1.
5. Log In: Once you’ve accessed the setup page, you’ll likely need to log in. Again, the default username and password are often ‘admin/admin’, but check your manual for specifics.
6. Setup Wizard: Many repeaters will have a setup wizard that guides you through the process. If yours does, simply follow the on-screen instructions.
7. Select Your Home Network: You’ll be asked to select the WiFi network that you want to extend. Find your home network in the list and select it.
8. Enter WiFi Password: Input the password of your existing home WiFi network.
9. Configure Repeater Settings: You might have the option to change the repeater’s network name (SSID) and password. You can keep these the same as your existing network for seamless connectivity or set a different name and password if you prefer.
10. Save and Reboot: Save your settings. The repeater will likely reboot to apply these settings.
11. Test the Connection: Once the repeater restarts, connect your device to the repeater’s network using the new SSID and password, if you changed them. Check if you have internet access and improved signal strength in the desired area.
12. Adjust Placement if Necessary: If you’re not seeing a significant improvement, you may need to adjust the repeater’s location.

Remember, each repeater can have slight variations in setup process, so it’s a good idea to have the manual handy for model-specific instructions.
