    Verify ISP compatibility

    Consult your ISP website to confirm if they allow third-party routers and if your specific model is compatible with their network. Ensure your account is active and you have your login credentials ready for the ISP mobile application or customer portal.

    Note: Some fiber providers require a specific ONT that must remain connected to your new router.

    Disconnect the rental router

    Power off the existing rental router by unplugging its power adapter from the wall outlet. Locate the Ethernet cable connecting the modem to the rental router and detach it from the WAN/Internet port on the rental device.

    Note: Label your cables before removing them to prevent confusion.

    Connect the new router

    Connect the Ethernet cable from your modem's LAN port to the WAN/Internet port on your new router. Plug in the new router's power adapter and wait for the status lights to indicate a stable connection, typically signified by a solid white or green LED.

    Note: Use a Cat6 or higher Ethernet cable for optimal speed.

    Access the setup interface

    Connect your computer or phone to the new router's default Wi-Fi network using the credentials printed on the device label. Open a web browser and enter the default IP address, such as 192.168.1.1 or 10.0.0.1, to access the admin dashboard.

    Note: Check the bottom of the router for the specific admin URL or IP.

    Configure network settings

    Follow the on-screen prompts to set your Network Name (SSID) and a strong WPA3 password. If your ISP requires a specific connection type like PPPoE or Static IP, enter those details now in the WAN settings menu.

    Note: Reboot your modem after the router setup to ensure it registers the new MAC address.

    Return the rental hardware

    Take the rental router to your ISP’s local retail store or ship it back using a provided return label. Obtain and save a receipt as proof of return to ensure the monthly rental charges are removed from your billing account immediately.

    Note: Never discard ISP hardware as you will be charged a full replacement fee.
