Someone should tell ZyXEL that's called antenna diversity, not MIMO :) I wonder if they do diversity/antenna switching externally from the ZD1211 hardware. If they use ZD1211 functionality for diversity, it may explain why the current antenna never changes: our driver doesn't support the ZD1211 diversity features (and neither does the vendor Linux driver really). One interesting test would be doing the same experiment under windows and seeing if the lights change. Finally tried this under Windows - the switching is indeed performed from the driver.

[zd1211-devs] New device ID for zd1211rw driver
Hello,
I'm writing to contribute a new device ID for the zd1211rw driver.
Product: ZyXEL M-202 XtremeMIMO USB Adapter
USB IDs: 0586:340a
Chip ID: zd1211b chip 0586:340a v4810 high 00-13-49 AL2230_RF pa0 S
FCC ID: SI5WUB221Z
Driver code: { USB_DEVICE(0x0586, 0x340a), .driver_info = DEVICE_ZD1211B },
I have successfully used this configuration in a WEP-encrypted
infrastructure network.

Thanks for the report. It's very interesting: MIMO is the technology
used to drive 802.11n (multiple simultaneous data throughput channels)
but the ZD1211 hardware does not support this (it only has a single
radio). The ZyXEL website doesn't really explain how they are using MIMO
in this device. Just curious, do you have any ideas?
The extent of my knowledge about this product is that it ran me about
$12 last week from TigerDirect :-).
It claims to have three antennas inside its little box - pointing up,
left, and right - with LEDs indicating which one is in use. Oddly
enough, the same LED lights up regardless of how I orient it w.r.t. the
AP. I also notice that all the literature calls it 802.11g - not
802.11n. My guess is that it's a garden variety, gimmicked-up 802.11g
desktop dongle.

I checked the windows driver and it does seem to be just a ZD1211B,
nothing new...
I'll submit the ID addition in a few minutes. Thanks!
Daniel
