It supports superchannel without any license update. Just go to wireless settings and set wireless-mode=superchannel

Thanx normis i do that but when i make another Metal Station and search about super channel nothing appear i make wireless settings and set wireless-mode=super channel in AP and station and nothing appear in scan option

you must enter the AP frequency in the "scan list" setting on the client device. Otherwise it will not know that your AP is set to some non standard frequency
