Hi.
Can we set a WiFi device as specific mode?
Specifically, I want Marvell 88W8887 802.11bgnac device in my OpenWRT put as 802.11ac or 802.11nac.
Is it possible? Which material should I refer to?
Is this the third radio on a WRT3200 / WRT32X?
Yes. Correct.
How did you know that? O.o?
Does this help?

Because I own that same device... 
Unless you have a very specific need, or are just experimenting, I would not tinker with that radio, and just disable it.

Yeah. Agree with your way.
But only thing I regret is that abandon(disable) expensive equipment(the third device) since poor network performance....
The manufacturer never intended it to be used in the first place, its only original purpose was doing regular DFS scans in the background, without blocking the real wireless cards (although I have no idea if this goal was ever properly implemented).

Hey guys,
I think this is better way to user all the device.
nano /etc/config/wireless
config wifi-device 'radio0'
option require_mode 'ac' <-- HERE ADDED to limit as AC mode.
Think that better than disabling. What do you think?
It is still crap. To my knowledge, there is no external antenna, so it has really limited connectivity.
Feel free to experiment, but do not expect any performance from it. And please pay attention to the discussion about the third radio causing trouble for the main mwlwifi radios if its config is not quite in sync with the real radios.
