NetworkManager + Mobile Broadband

[vh-bil]

I am having problems with the NetworkManager. It only sometimes shows my USB mobile braodband device in the list of networks I can connect to. I think the device is not discovered my system sometimes.

Is there a way to have my internet more reliable and stay in the NetworkManagers drop down list?

The model of the modem is MF626

Thank you for your help.

I've occassionally had problems with NetworkManager and mobile broadband. These days I use Vodafone Mobile Connect to connect to my mobile broadband service instead of NetworkManager. Although its named "Vodafone Mobile Connect", it works with any network as long as you enter the right dial up settings.

I think the problem is with the mobile cdrom driver built in it that stores the windows drivers for the device.

What I have been doing to get it working is boot up my windows VirtualBox with the ZF626 drivers installed, and then hyperterm into it using:
115200 – Bits per second
8 – Data bits
None – Parity
1 – Stop bits
None – Flow Control

then send these commands:
AT+ZOPRT=5
AT+ZCDRUN=8

I then shut down VirtualBox and then it will work in Linux.

This command will get results only after the firsts steps have been taken in VirtualBox:
ls /dev | grep ttyUSB
ttyUSB0
ttyUSB1
ttyUSB2

I am hoping someone knows a way for Linux to see the USB serial ports with out going to that trouble.
