Hi Markus,<div><br></div><div>Indeed, I realize that anything below reported connection speed of 150Mbit/s (regardless of actual throughput sustained by the IP stack) could indicate only one chain is active.</div><div><br>
</div><div>My suspicion that perhaps both chains are active, tho not actually connecting due to non-ideal SNR, comes from what a Nano M5 reported briefly after power up. A single chain wouldn't report 240Mbit/s, correct?<br>

For an update, I believe I was able to get HT modes working in IBSS (aka adhoc) on two Nanostation M5s. The Links reported 150Mbit/s connection on both ends after settling, and throughput measured at 45Mbit/s.<div><br></div>
<div>This required patches to iw and compat-wireless on OpenWRT r25206. More info here:<br><a href="https://forum.openwrt.org/viewtopic.php?pid=131299#p131299" target="_blank">https://forum.openwrt.org/viewtopic.php?pid=131299#p131299</a></div>
<div><br></div><div>I would be interested to hear if anyone has been able to specify HT modes in /etc/config/wireless on OpenWRT, since I was unable.</div><div><br></div><div>Note that the link speeds did suggest I was getting multiple chains (i.e. MIMO) very briefly.

Sorry for not explaining this in the original post.

</div>Since Ubiquiti M5 devices are not as identical as the pre-M series,<br>
could you be more specific?<br>
<br>
These three categories are quite distinct, require different firmware<br>
and have their own, distinct quirks:<br>
- PicoStation / Bullet M5<br>
- NanoStation M5<br>
- NanoStation M5 Loco<br>
<br>
Cheers,<br>
