How do I change my Wi-Fi frequency?

The frequency band is changed directly on the router:

1. Enter the IP address 192.168. 0.1 in your Internet browser.
2. Leave the user field empty and use admin as the password.
3. Select Wireless from the menu.
4. In the 802.11 band selection field, you can select 2.4 GHz or 5 GHz.
5. Click on Apply to save the Settings.
