Separating the 5GHz and 2.4GHz bands on your router typically involves a few key steps, although the exact process can vary depending on the make and model of your router. Here's a general guide:

1. Access Router Settings: First, you need to access your router's settings. This is usually done by entering the router's IP address in a web browser. Common addresses are `` or ``. You'll need to enter your username and password.

2. Locate Wireless Settings: Once logged in, navigate to the wireless settings section. This might be labeled as 'Wireless', 'Wi-Fi', or something similar.

3. Rename SSIDs: Your router might have a single SSID (network name) for both the 2.4GHz and 5GHz bands. To separate them, you can rename one or both SSIDs. For example, you could name them "[YourNetworkName]_2.4GHz" and "[YourNetworkName]_5GHz".

4. Adjust Security Settings: Ensure both networks are securely protected, preferably with WPA2 or WPA3 security. Set a strong password for each SSID.

5. Save and Apply Changes: After making these changes, save them and apply. Your router may reboot.

6. Connect Devices Appropriately: After separation, you'll see two different networks when connecting devices. Connect older devices that only support 2.4GHz to the 2.4GHz SSID, and newer devices to the 5GHz SSID for faster speeds.

7. Check for Advanced Features**: Some routers offer advanced features like band steering or smart connect, which can automatically connect devices to the most appropriate band.

8. Firmware Update: Ensure your router's firmware is up to date for optimal performance and security.

9. Check Router Manual: If you're unsure about any steps, consult the manual for your specific router model or check the manufacturer's website for more detailed instructions.

Remember, the 5GHz band typically offers faster speeds but has a shorter range, whereas the 2.4GHz band has better range but might be slower, especially in crowded areas with a lot of overlapping networks.
