Mikrotik base frequencies?

Question

WiFi

The problem is the following. There is a 962UiGS-5HacT2HnT router. Firmware 6.45.8. It creates 2 wireless networks, one - 2.4 Ghz -B, G and the second 5 Ghz AC only. No questions from the first. It is impossible to connect any device to the second one. In 5ghz console: denying assoc to 64:B8:53:5F:58:00, does not support all basic rates. It is clear that the problem is in the base frequencies, but unfortunately, I cannot find any combination at which the network would work. In general, I looked through the manuals everything I found. Result is the same

Answer 1

It was not necessary to post so many pictures, a text config would have been enough.

/interface wireless
set [ find default-name=wlan2 ] antenna-gain=0 band=5ghz-onlyac channel-width=20/40mhz-Ce country=russia3 disabled=no frequency=auto installation=indoor mode=\
    ap-bridge security-profile=home ssid=<You_SSID> wireless-protocol=802.11 wmm-support=enabled wps-mode=disabled

The rest is default.
PS
The channel width is too much for you, that's why it doesn't work.

Answer 2

My guess is that the etsi standard might not work with 5Ghz.
/interface wireless> info country-info etsi
Try selecting the actual country while resetting the other settings to their original state. In my current firmware, there is no etsi at all - there are etsi1 and etsi2 with a different set of frequencies.

Answer 3

I had something similar, changing the country to the states helped ...
