My RB4011iGS+5HacQ2HnD-IN… 5G down for unknown reason, there is nothing shown in the log as well.
Running 6.44 for 4 full days, and only just happen a moment ago. After reboot, everything back to normal.
Could it be that 5G radio channel is set to auto and that the selected channel is not supported by your device? Or that it was in a DFS waiting state? Perhaps you can share your settings?
/interface wireless
set [ find default-name=wlan1 ] band=5ghz-onlyac channel-width=20/40mhz-eC
country=thailand disabled=no frequency=5280 mode=ap-bridge ssid=
Internet5G wireless-protocol=802.11
It was running fine, but only earlier that the 5G band down, and I have to connect to 2G to reboot it.
And I was connected for all days long watching Netflix. Just curious, what was happening.
Problem device, no solution.

Thank you, I had been reading your post as well. Wondering will it be fixed sooner or later.
