SETUP
Linksys has simplified things in this area so once you launch your favorite internet browser the setup procedure starts automatically.
Here the setup program will check for available firmware updates and then will ask you to name (SSID) the two bands.
Of course if you want you can manually update the firmware by downloading it from the official Linksys support page.
You can also change the access password and create a smart Wi-Fi account.
We got this message once we finished the installation but we didn't have to do anything with the firmware afterwards (probably a software glitch).
