Fix Zidoo X9S WIFI issue

When I bought the X9S device, I did not know its WIFI was so not stable.

Sometimes, when I am watching movie, I have to disable/enable WIFI several times as the connection status will become fake and could not play movie for me.

This issue confused me for a long time and I could not fix it.

While several days ago, when I checked the kernel log, I found below information:

[   72.514156] RTW: rtw_set_ps_mode(wlan0) Enter 802.11 power save - WIFI-TRAFFIC_IDLE
[   72.523698] RTW: rtl8812_set_FwPwrMode_cmd: Mode=2 SmartPS=2 UAPSD=0
[   73.721096] RTW: rtw_set_ps_mode(wlan0) Leave 802.11 power save - WIFI-LPS_CTRL_LEAVE
[   73.729388] RTW: rtl8812_set_FwPwrMode_cmd: Mode=0 SmartPS=2 UAPSD=0
[   74.514328] RTW: rtw_set_ps_mode(wlan0) Enter 802.11 power save - WIFI-TRAFFIC_IDLE
[   74.522213] RTW: rtl8812_set_FwPwrMode_cmd: Mode=2 SmartPS=2 UAPSD=0
[   76.514363] RTW: traffic_status_watchdog(wlan0) acqiure wake_lock for 4500 ms(tx:93,rx_unicast:158)
[   76.523675] RTW: rtw_set_ps_mode(wlan0) Leave 802.11 power save - WIFI-TRAFFIC_BUSY
[   76.531603] RTW: rtl8812_set_FwPwrMode_cmd: Mode=0 SmartPS=2 UAPSD=0

So it seems X9S has the WIFI power save mode enabled, and run below command to confirm my assumption.

root@X9S:~# iw wlan0 get power_save
Power save: on

I wanted to disable it automatically and wrote some simple commands to the /etc/rc.local file.

root@X9S:~# cat /etc/rc.local
# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
IPADDR=192.168.13.25
while true; do
/sbin/ifconfig | grep "$IPADDR" >/dev/null
if [ $? -ne 0 ]; then
sleep 1
else
/sbin/ifconfig >/var/log/wlan
/usr/sbin/iw wlan0 set power_save off >> /var/log/wlan
break
fi
done &
exit 0

The IPADDR is the assigned ip of the wireless adapter and after such change I played two movies and it worked really well.

 

Update: I found another more important reason of this issue was about the SMB settings on the DSM system, please check below screen shot:
