Hi,
I have two Mikrotik RB911AC boards (radio based on QCA9882) in which I injected OpenWRT 15.05 and ath10k.
I managed to get them connected in AP/STA configuration in a very short (2 meters) distance, but when I try to connect them on 5 kilometers, even if I set the distance parameter on OpenWRT's UCI config files properly, it tries to connect but after 3 retries, it declares unauthenticated.
No problem with the same firmware on ath9k, for example.
Signal is stable at -62 dbm, I also tried to change channels and push tx power, but nothing helped to do the trick.
Also tried with every firmware combination (10.2.4, CT firmware, 999.999.0.636, 10.1.467.2-1), without success.
Is there anybody who can tell me why? Could it be due to the kernel version (i'm running on 3.18.21)?
Thanks in advance,

CT 4.0 or 4.2? 4.0 is most stable currently, though the last few days I've been committing a lot of barely tested code. Will test this better shortly.

As far as I know, the 'official' ath10k dev kits use the same firmware that is available on the public git firmware tree, so probably firmware performance is similar unless some third-party company has acquired firmware source code and put some considerable effort into it. My CT firmware is primarily focused on stability and features. I have not made a lot of effort to try to optimize speed, though I have had a few people tell me my firmware was faster, and I don't recall anyone telling me it was slower. I suspect it is basically about the same. Possibly a very recent linux kernel + ath10k driver is more efficient than reference driver OS's, but I am guessing that would depend greatly on how the reference OS is tuned for the hardware in question. I test on x86 primarily, and have plenty of CPU, so I haven't been worrying too much about CPU resources on the host.

Then, openwrt would need to know how to set the value through debugfs. Maybe someone in openwrt can work with me to get this working sometime soon.
