Hi,
The 703N can only supply 200mA out the USB port, Its likely this issue is caused by the device using more power that can be supplied and the device resetting. TP-Link have a compatibility Martix for devices, It is based on Power consumption, Not just drivers in stock firmware. Mitch Kelly.

After establish 3g connection, we find 3g connection disconnect very soon. But this problem doesn't exist if we connect this usb dongle to another router. Would you can give me any suggestion?
