have you tried it with a short distance?
If you did you should better ask Ben Greear directly.
By the way ath10k gen 2 chipsets don't work very well with long distance links without a
special feature which implementation is only available to companies like Ubiquiti and very few
people who have an own reverse-engineered implementation.
It works on IPQ401X, QCA9886 and QCA9888 based chips only.
And it is not possible to set a coverage class for gen 2 devices, yet as far as I know due to missing
documentation and implementation (correct me if that information is outdated).
Furthermore a high channel width often results in problems
due to lower receiver sensibility.
We have better experiences with lower channel widths and sometimes get more throughput with that.
Actually I think this does not explain your connection issues as 13 km is not that much.

Vincent Wiemann

After i installed openwrt and ath10k ct driver, kmod ath10k and board-2.bin the device can run a 80MHz channel in WDS AP. The problem is that it won't run as station or station wds. It can scan
