I'm using rooter Huntsman 2014-01-25red with my aircard 320u modem. I can't get my celcom connected. The network LED is blinking (blinking yellow in 4G or blinking blue in 3G).

The modem can connect if I plug it directly to my PC.
Below is the settings:
APN : celcom3g (also tried celcom.net.my)
User Name : (blank)
Password : (blank)
PIN : (blank)
Authentication Protocol : PAP (also tried none and pap)
Force Modem to PPP Protocol : No
USB Power : On
Connection Delay in Seconds : 5
Is the setting above correct?

EDIT:
Finally manage to make it work with a weird trick.
1. Plug 320u into router. Set Current Cellular Mode as "3G preferred".
2. Plug the 320u directly to PC. Use Aircard Watcher to set "WCDMA all".
3. Plug 320u into router. It connects to internet with 3G (steady blue). Set Current Cellular Mode as "4G preferred". It will switch to 4G mode (steady green). Yay! 4G Internet works fine but without stats for MCC MNC & Maximum Qos (shows --).
I'm now using APN "celcom.net.my" with Authentication protocol "None". I guess it doesn't matter.
EDIT2: After router restart, I have to do all of the above again
Anyone know what's the data port and comm port for sierra 320u?
