i'm trying out Xubuntu 12.04, preference was due to hardware specifications of my machine. My problem is my broadband connection using a USB Huawei modem and Sun Telecoms Philippines keeps getting disconnected.

I've read in Ubuntu forums that this may be due to the USB Autosuspend. How can USB Autosuspend be disabled?

I'm not using powernap or powertop, is there a way i can disable usb autosuspend from the terminal?

How about setting the auto-suspend threshold time for your specific device to a very high amount - as described by this forum thread? – jhohlfeld Apr 30 '13 at 6:50
