The netbook can sometimes, sometimes not, connect to the internet mobile broadband 3G (or 2G GSM) via USB 3G modem.
For it to connect to mobile broadband (when it can) I have, after sticking the modem into the USB port, and then enter the shell prompt with the command:
Then I have to restart the network-manager:
Service network-manager restart
The shell reports the number xxxx this process.
Entering the command:
Then, I annotate the number yyyy of the process
Then I change the priority of these two processes for priority for maximum priority:
renice -20 xxxx yyyy
So, sometimes, I get a 3G connection. I do not know if he can connect on 2G (GSM), but it seems to me that when the connection changes from 3G to GSM she soon falls - but I am not sure.
- When the connection is not achieved, the modem-manager is constantly trying. It can be seen that through the connection icon in the upper right side of the screen.
Yesterday, Saturday 12/Jan/2012 I tried to connect to the internet and could not. The system detected an error and asked me if I wanted to send an error message. I accepted, but as I was not connected to the internet, I copied the details of the problem. Today, Sunday 13/Jan/2012 I got the connection and I sent you the error report. The error details are below (may have some copy error because the report is very large):
