No internet connection with 5Ghz

Hello.
hAp AC Lite.
My settings:

add authentication-types=wpa2-psk eap-methods="" management-protection=allowed \
    mode=dynamic-keys name=WF5 supplicant-identity="" wpa2-pre-shared-key=\
    somepassword
/interface wireless
set [ find default-name=wlan2 ] band=5ghz-a/n/ac channel-width=20/40/80mhz-Ceee \
    country=russia disabled=no frequency-mode=regulatory-domain mode=ap-bridge \
    name=wlan5Ghz security-profile=WF5 ssid=5Ghz wireless-protocol=802.11 \
    wps-mode=disabled

I have 3 devices with 5Ghz support: all of them successfully connecting to wifi but non of them have connection to my network. Wifi status of any device is “not connected to the internet”. I tried nearly all combinations of band, channel widt and frequency (wasn’t certain if it’s a part of a problem). Also tried default security profile without password. 2.4Ghz with pretty much the same settings (i mean the same network, country etc.) works perfectly. Can you help me to detect the problem?

Post an /export hide-sensitive

Do you have DHCP server configured for 5G interface?

If you can connect ok to wifi, but have no internet access, it will have to do with your network / router configuration. Please post your config
