Dear all,

I=92m currently doing me masters thesis on the subject of Wireless Mesh
Networks and how to optimize them for home use.
The devices I use are 5x PC Engine APU2c4 with 2x QCA9880 chip (Compex
WLE900VX). All of them are running LEDE (OpenWRT fork).

The problem I=92m experiencing is the same as
http://lists.infradead.org/pipermail/ath10k/2017-January/009075.html . Using
the tips mentioned I did not come to a better performance. I=92m thinking i=
t=92s
driver related..
When running iperf3 only one direction is running at a reasonable
throughput. Since I am using adhoc mode primarily I decided to use these
packages:
-	Kmod-ath10k-ct
-	Ath10k-firmware-qca988x-ct
Some sources on the internet said that using the Candela Tech drivers should
result in better support for adhoc/mesh networks.

As suggested in the other issue linked above, I switched TCP congestion
control to =91Reno=92 instead of the default =91Cubic=92. =

I also did try the command =93iw reg set BE=94 since I am from Belgium, but
running =93iw reg get=94 right after still gave me US as a result.

Let me know what additional command info I should post. Any help would be
greatly appreciated.
