Does my router support 5 GHz Wi-Fi? How do I connect to its
5 GHz Wi-Fi?
1. Yes. Your router supports 5 GHz Wi-Fi, which is faster and
less sensitive to interference. However, it does not penetrate
walls as well as 2.4 GHz Wi-Fi and can only be used on
devices that support 5 GHz Wi-Fi.
2. If you have enabled the feature that prioritizes 5 GHz on your
router, the 2.4 GHz and 5 GHz networks will share the same
network name and you will be automatically connected
to the faster network. If this feature is disabled, two Wi-
Fi network names will be displayed. Connect to the Wi-Fi
network ending with "_5G". You can manage this feature in
your router's web-based management page.
If you are experiencing any other issues with the router:
1. Restart the router.
2. Restore the router to its factory settings.
3. Contact your carrier.
