Some AR9344 boards do very poorly with the default settings and need custom rxdv-delay, rxd-delay, txd-delay, txen-delay flags to perform reasonably. In this case the WD My Net Wi-Fi Range Extender can not even manage 10Mbps on a 1Gbit link: root@AR9344:~# iperf3 -s ----------------------------------------------------------- Server listening on 5201 ----------------------------------------------------------- Accepted connection from client [...] [ 5] local [...] connected to client [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 1.09 MBytes 9.16 Mbits/sec [ 5] 1.00-2.00 sec 895 KBytes 7.33 Mbits/sec [ 5] 2.00-3.00 sec 762 KBytes 6.25 Mbits/sec [...] [ 5] 10.00-10.03 sec 17.0 KBytes 4.74 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate [ 5] 0.00-10.03 sec 9.00 MBytes 7.52 Mbits/sec with but with the correct settings in place, it does much better: root@AR9344:~# iperf3 -s ----------------------------------------------------------- Server listening on 5201 ----------------------------------------------------------- Accepted connection from client [...] [ 5] local [...] connected to client [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 23.1 MBytes 193 Mbits/sec [ 5] 1.00-2.00 sec 23.1 MBytes 194 Mbits/sec [ 5] 2.00-3.00 sec 23.2 MBytes 195 Mbits/sec [...] [ 5] 10.00-10.04 sec 710 KBytes 180 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate [ 5] 0.00-10.04 sec 237 MBytes 198 Mbits/sec The tx data and enable delay bits definitions are taken from Atheros' AR9344 Data Sheet Section "8.6.1 Ethernet Configuration (ETH_CFG)" on page 153.

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
