After taking a lot of time looking at many disperse threads... I looked at a thread for ZTE MF626 that was essential...(http://ubuntuforums.org/showthread.php?t=1302235).
This was used to connect a ZTE MF100 in Brasil with the VIVO 3G network.
Part one (use windows to turn off the usbdrive option).
1. Connect your ZTE MF100 to the USB port of your computer with hyperterminal on it. The modem will automatically install the appropriate drivers and launch the User Interface (UI).
2. Determine the COM port of the modem by inspecting the modem properties under Modems in the Device Manager (do not get confused with ZTE Dianostics Interface or others).
3. Close the UI and open hyperterminal (or equivalent) and connect to the appropriate COM port using these parameters:
Speed: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow Control: None
4. Input the following command (you may wish to turn on local echo so you can see what you are typing):
AT+ZCDRUN=8
You should receive the following back in confirmation:
Close autorun state result(0:FAIL 1:SUCCESS):1
5. Close the hyperterminal connection and unplug the modem. Your modem is now reconfigured to be plug and play in Ubuntu.
Part 2 (Ubuntu)
6. Connect you modem to your Ubuntu computer. In the NetworkManager Applet you should find the option to create a new mobile broadband connection. Do so with the location and APN appropriate to you ISP.
You should now be able to connect successfully to the internet and your modem should function as a plug and play device in Ubuntu. This works by disabling the self installation and autorun features which would otherwise cause Ubuntu to detect the modem as a CD-ROM. If you wish to revert the modem to it's orginal settings to allow atomatic UI installation on windows PCs the command to do so is: AT+ZCDRUN=9 (administered by hyperterminal as above)
The original thread finishes here...
What I add now:
After finishing all the steps I could ping my servers IP address with Terminal but no WWW surfing (the DNS was not working... ).
SO:
Open TERMINAL and type:
sudo sh /etc/ppp/ip-up
The ip-up script will correct the DNS for you....
Now open firefox and everything will be fine!!!!!!!!!!!
Cheers
