Hi Amitkumar,
Yet another observation with RS-9113 module.
I managed to setup an access point on my board with RS-9113 connected either
via SDIO (this one is soldered on my board) or via USB (this is your RS9113
Evaluation Board Rev 4.0).
But regardless the module I use I still see the same bandwidth figures.
RS-9113 sends data at ~100 Kbits and receives at ~1.5-2 Mbits.
See below results of iperf3 runs (from development host side).
The board with RS-9113 acts as a server:

The board with RS-9113 acts as a server (but with "-R" it sends us data now):

My configurations are as below.
hostapd.conf:

interface=wlan0
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=AP_NAME
hw_mode=g
channel=1

wpa_supplicant.conf

ap_scan=1

psk="password"
}

Note I use vanilla Linux v4.14.4.
I'm wondering if you may see different results in your setup and if so
could you please suggest something for me to try.
Thanks in advance,
Alexey
P.S. I do remember about my previous email but so far I was not able to
get with the board to the place with "problematic" Wi-FI AP, once I get
there I'll grab longs for you.
