Short answer
Yes, you can.
I have capsman setup with 5ghz out of the controller so I can use it for my own purposes
But as indicated by erlinden, why use capsman ? For only 2 APs ?
And yes, Audience allows usage of wifiwave2, so another reason not to use capsman.
Because... He doesn't know how bad Mikrotik radios are.
If caps-man could control a good radio... It would be the best one panel interface I have seen.
2 radios only?
Are you kidding... Have you used caps-man?
When it's working... I can log into the router and see in almost live time exactly what each wireless client is doing. You can see the devices move between radios in real time. Establish access control rules. Enable or disable SSIDs based on anything (like the primary ISP going down to save bandwidth on your metered back up ISP).
Unfortunately... It (caps-man) works with Mikrotik's old proprietary radio drivers. These drivers have UNCORRECTABLE ISSUES. These issues have been brought to Mikrotik's attention for years. And I noticed in the last few years... Mikrotik actually eluding to them on this forum. Actually posting that the customer had picked the wrong gear when they selected a Mikrotik radio.
I applaud them for finally admitting to it.
But... Man... Do I wish Caps-Man could could control a good radio. I think I have said it out loud, every day, for the last 4 years.
