Hi Aka,
Thanks again, the wireless authentication is now working, but I hit another issue that it will turn off by itself when the rpi session is idling
I have do some read out and this could the potential cause:

1. Upgrade the wireless firmware
sudo BRANCH=next rpi-update
2. Turn off power management.
sudo iwconfig wlan0 power off
Can this be integrate to WTware?
Again your help is very much appreciated.
Additional link info:
It also mention on the be link that it will improve the wireless self turn off and performance issue.

Signal level is low. Try USB WiFi with external antenna.

Hi Aka,
Just want to keep you updated.
1. Turning off wireless power management does help to improve rpi 3 wireless connection please keep the setting.
2. After further checking I realize that the connection drop off due to timeout session configure from wireless lan controller.
3. I have further fine tune the wpa_supplication and the wireless connection seem to be more stable now.
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="coyssid"
scan_ssid=1
proto=RSN
key_mgmt=WPA-EAP
pairwise=CCMP
eap=PEAP
identity="myusername"
password="mypassword"
phase2="auth=MSCHAPV2"
priority=1
}
Thanks,
Ken

Just to keep you updated:

2. The disconnection was cause by wireless lan controller session timeout setting.
3. I am fine tuning the wpa_supplication config file seem to connect better now, still monitoring the outcome.
My wpa_supplication config
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="coyssid"
scan_ssid=1
proto=RSN
key_mgmt=WPA-EAP
pairwise=CCMP
eap=PEAP
identity="myusername"
