Step-by-step
-
Begin by connecting one end of your Ethernet cable to the LAN port of your BGW320 gateway. Ensure that the connection is secure and that the port is functioning properly.
-
Run the Ethernet cable to your RAX120 router. Make sure the cable is not pinched or damaged during this process. If needed, use cable clips to secure it along the walls.
-
Connect the other end of the Ethernet cable to the WAN port of your RAX120 router. Again, ensure that the connection is secure.
-
Power on your RAX120 router and wait for it to boot up completely. This may take a few minutes. Look for the status lights to confirm that it is functioning correctly.
-
Using your computer or mobile device, connect to the Wi-Fi network of your RAX120 router. The default network name (SSID) and password can be found on a sticker on the router.
-
Open a web browser and enter the IP address of your RAX120 router (usually 192.168.1.1) to access the admin interface. Log in using the default credentials provided by the manufacturer.
-
Once logged in, navigate to the WAN settings and ensure that the connection type is set to DHCP. This allows your RAX120 to receive an IP address from the BGW320 gateway.
-
Next, configure the wireless settings of your RAX120 router. Set your desired SSID and password, and choose the appropriate security protocol (WPA2 is recommended).
-
After configuring the wireless settings, check the LAN settings to ensure that the DHCP server is enabled. This will allow your RAX120 to assign IP addresses to devices connected to it.
-
Save your settings and reboot the RAX120 router to apply the changes. This step is crucial for ensuring that all configurations take effect.
-
Once the router has rebooted, reconnect to the RAX120 Wi-Fi network and test the internet connection by visiting a website. If successful, your setup is complete.
-
Finally, consider setting up VLANs if you have IoT devices. This can be done in the VLAN settings of your RAX120 router to isolate these devices from your main network for added security.
Best practices & security
To ensure your home network remains secure, it is essential to follow best practices during and after setup. First, always change the default login credentials of your routers to something more secure. This will prevent unauthorized access to your network settings.
Next, regularly update the firmware of your routers and devices. Manufacturers often release updates to fix vulnerabilities and improve performance. Keeping your devices updated is a simple yet effective way to enhance security.
Additionally, consider enabling WPA3 security if your devices support it. This is the latest wireless security protocol and offers improved protection against unauthorized access. If WPA3 is not available, ensure that you are using WPA2 with a strong password.
Common pitfalls & troubleshooting
One common issue during setup is failing to secure the Ethernet connections properly. Ensure that cables are fully inserted into the ports and that there are no visible damages. If you experience connectivity problems, check the physical connections first.
Another pitfall is neglecting to configure the WAN settings correctly on the RAX120 router. If the connection type is not set to DHCP, the router will not receive an IP address from the BGW320, leading to connectivity issues. Double-check these settings if you encounter problems.
If you find that devices are not connecting to the Wi-Fi network, ensure that the SSID and password are correct. Additionally, verify that the wireless settings are configured properly, including the security protocol. Restarting the router can also resolve temporary issues.
