I have a Huawei E172 USB dongle that works perfectly with Precise. However it keeps on disconnecting the internet connection when I'm not doing anything that requires internet connection. I think it has to do with Powertop tunables. I have turned so many things off in this section. Here is the list of the things I turned off:

Here is the screenshot of the tunable section in Powertop

    I think that you enabled autosuspend for USB while relying on USB for your internet connection :-) I don't use powertop, because I lack a deep understanding of what it actually does.

  • I have now turned off autosuspend for anything 'USB' related to see if that will stop this. I'll report back if this is successful

  • Indeed not turning things related to 'USB' solves the issue of disconnection

You can try changing the state of your mobile broadband from the Tunables tab.

As the Powertop web site doesn't have any useful documentation, I was unable to find any concrete answers. However, you can have a look at the website: http://www.lesswatts.org/projects/powertop/

  • You are so right about the lack of documentation with regards to Powertop

A temporary solution would be to prevent the internet connection from idling with a simple script.
Create file /etc/cron.d/ping

# /etc/cron.d/ping
# ping every one minute
* * * * * nobody ping -c 1 -W 10 -q www.google.com >/dev/null 2>&1
