Hi,<br><br>I have a question how Network Manager switches from 3G to 2G automatically. Are there some scripts to let him do it ? And how measure the signal quality of 3G or 2G ?<br><br>Is there a way to let Network Manager release device when the internet connection is on ?<br>
<br>Thanks for your attention, Your answer will be appreciated.<br><br>Best wishes.<br><br>Lu QIAO<br>
