I have the same problem 5.0 GHZ turned on in but The MAC address of 5GHz-1 and 5GHz-2 is empty. I cant find any solution...

Perhaps your router decided to retire. In this case your only solution is a new router.

If the router's hardware is defective firmware change won't help.

if you cant see the MAC ID in the setup page, then the radio has gone kaput. I also have a RT-AC5300 where the high band 5ghz radio is gone. It is hardware issue and nothing will bring it back ...

So should i throw this and buy new or what is the suggestion ?

You can throw it away and buy a new All-In-One home router or you can use it as a Wired Router with radios disabled and antennas removed feeding an Access Point. This is the most cost-effective solution. Something like EAP245v3 is about $90 and comes with PoE injector. This RT-AC5300 router has older hardware, no firmware update for >1 year and seems like it's in unofficial End-of-Life state. It will never receive 388 firmware either. If only one Access Point (AIO router) is needed for your place I personally would buy an new AIO router, but not an overpriced tri-band spider model. More like compact size and much newer and faster hardware RT-AX86S. It's about $140 on sale. I don't know what country you live in though and what your local market is.
