Problem with MT300N-V2 and Huawei E3131 USB 3G DONGLE

Hello, when i turn on (plugging in usb) my MT300N mango router with HUAWEI E3131 3G USB KEY, mango don’t connect 3G network but stay on the following screen:

chrome_Mz1O8KRQGK

so i must disconnect actual broke 3g connection and click “automatic setting” or go into “manual setup” and click “apply” so

then is ok… but i need it automatically connect when power on, is there a way to do this?

Can you post the screenshot of the manual config which is the correct settings?

What firmware version are you using?
