Question about how Network Manager switches from 3G to 2G automatically

[Lu QIAO]

Hi,

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 ?

Is there a way to let Network Manager release device when the internet
connection is on ?

Thanks for your attention, Your answer will be appreciated.

Best wishes.
