Mikrotik SXTSA5AC 90 Sector Not Able to Enter Selected Channel Like 5180,5220,5540,5680,5745 in this format not accept, only 5100-5600 format work can anyone Help me for this
With legacy (wireless) driver, set
/interface/wireless
set [ find default-name=wlan1 ] frequency=auto scan-list=5180,5220,5540,4680,5745
In the new wifi (e.g. wifi-qcom-ac) both parameters are combined into single parameter like this: frequency=5180,5220,5540,4680,5745
Another possibility is to use channel lists:
/interface/wireless/channel
add list="ch36" band=5ghz-ac frequency=5180 list="my5G" width=20 extension-channel=Ceee
add list="ch44" band=5ghz-ac frequency=5220 list="my5G" width=20 extension-channel=eeCe
add list="ch108" band=5ghz-ac frequency=5540 list="my5G" width=20 extension-channel=eeCe
add list="ch149" band=5ghz-ac frequency=5745 list="my5G" width=20 extension-channel=Ceee
/interface/wireless
set [ find default-name=wlan1 ] frequency=auto scan-list=my5G
This form comes handy if one uses same list of channels for multiple configuration items. Also allows for "personalization" of individual channels (e.g. set non-standard width or extension-channel layout. It's also possible to (temporarily) disable individual channels in the list and wireless interface adjusts automatically.
BTW, if one sets channels as shown, then it's also possible to reference these channels in frequency assignment, e.g. /interface/wireless/set [ find find default-name=wlan1 ] frequency=ch149
