Below are the steps recommended by Linksys router support experts at Icognix.
Access the router’s web-based setup page using Linksys Connect.
*IMPORTANT: When making changes to the settings of the router, make sure to do it using a computer wired to the router. If you are using a laptop or any wireless computer, temporarily connect an Ethernet cable from one of the Ethernet ports of the router going to the Ethernet port of your laptop or wireless computer.
On the web-based setup page of your Linksys Wifi Router, click on the Wireless tab and select Manual.
NOTE: The details of your router’s current wireless settings will be displayed.
On the Basic Wireless Settings page, look for the 5 GHz Wireless Settings category located at the left hand side and enter your new wireless network name (SSID) according to your preference. Then click on Save Settings to apply the changes.
* QUICK TIP: You can retain the original SSID but may add a “- 5 GHz” suffix for you to be able to identify the 5 GHz network easily.
You will then receive a confirmation window stating that the Settings are successful. Click on the Continue button to return to the previous page.
