I've just purchased a new linksys wrt3200ACM and installed openwrt on it straight away. It has been a while since I ran a different rom other than stock, as I've been locked in to my ISP router. I want to make sure that I'm getting the best out of the router (one of the reasons of putting openwrt on it) but am not sure about the radio channels. How do I configure all these interfaces? Are there that many because it is a mu-mimo device? I'm currently working my way through the openwrt documentation and would be happy if someone pointed me in to the right place.
TIA (and apologies for not knowing more).
