Does MR60 support 802.11a Wireless?

Hello,

My son built a new gaming PC.  He bought various parts and put it together and installed Windows 11. It is working except the wireless part.  The motherboard spec says that it supports ***802.11ax Wireless**.    We use MR60 NightHawk as our wireless router.  Does MR60 support 802.11ax Wireless?  Could you please confirm that for me?

Thank you,

Mustafa
