5GHZ Network Disappearing
I have a six-week-old TP-Link Archer C1200 router. The past few days I've had issues with the 5GHZ network just cutting out. The 2.4 network continues working, but the 5GHZ network just goes away completely. My smart devices show they aren't connected, and it doesn't appear in the network list on my phones or computers. When I go to the config page, it doesn't show anything out of the ordinary. When I turn off WiFi broadcasting on the router and turn it back on, it works again for a while, but not for long. It was already on the latest version of firmware, but I refreshed it anyway. It's still doing the same thing.
I'm an IT Technician, so I'm somewhat knowledgable here, but I'm just trying to see if there's anything else I can try before getting it replaced.

The only other thing you can try to do is disable the 5GHz and re-enable it. If that doesn't work and since you are on the most recent firmware the next likely step is replacement.

I am experiencing the same issue.
I have a c2300 router and I am on "Smart Connect", however; the 5ghz band always drops off about a minute after a reboot. I have put a few devices within 6 inches of the router and still they only connect to 2.4ghz. For reference my network has 16 wireless devices and every single one of them are on 2.4ghz. In fact, using wifi analyzers there is no broadcast of the 5ghz band at all - despite the TPLink tether app (and web broswer) saying that it is enabled, and the LED light on the router saying it is active too.
I don't understand why ithe 5ghz band isn't visible to wifi analyzers and no devices are capable of connecting to it when in "smart connect".
With that said, if I enable ONLY the 5ghz band (ie. disable smart connect and 2.4 ghz) devices do connect fine. The 5ghz band does not seem to drop in this instance, as I have been connected for hours at a time.
For reference, when doing speed tests on the 5ghz band (when it is the only band broadcasted) I get 120+ mbps. Using the same device in the same location using the 2.4ghz band I get about 50 mbps, which is less than half. So this begs the question, why won't smart connect even broadcast the 5 ghz band or change my devices to a faster band to get the best connection? It certainly feels like a glitch in my opinion based on the firmware.
Note - I am well versed in networking too, and work in IT.

@kvnshffr Disabling the SSID broadcast helped for me, I had a similar issue.

First thing I'd check is IF 'Smart Connect' is enabled in Wireless settings? I ask as that could be the default setting in wireless, as you didn't state if you just got the router or if 5Ghz was visible before and now disappeared?
