Why do you think that only 1x2 or 1x3 was possible on these devices? 2x2
and 3x3 has been working just fine for a long time now, and it's enabled
by default where supported by the hardware.

You don't need to change anything, just use the defaults.
I have no idea what post from the list you're referring to, but here's a
piece of advice: It's not unheard of that sometimes people put wrong
things on the internet :)

Pickend this Info from The List that devices with openwrt are just transmitting at 1 stream but rec. at both. How can I change the settings? Also with uci or only with the iw-commands?
Tnx 4 support.

Hi,
If the device EEPROM states that it's a 2x2/3x3 device, it'll TX on
two/three streams.
If it's something like an AR9281 where it's physically a 1T2R stream
device, that's what it'll transmit/receive on by default.
If it's something like an AR9285 where it's physically a 1T1R stream
device with antenna diversity, that's also what you get.
If the device EEPROM lies though, well, that's a problem. :-)
