Starting from Ubuntu 9.10, Network Manager uses ModemManager to communicate with mobile broadband (CDMA, UMTS and others) cards. Ubuntu 9.10 uses version 0.2 of ModemManager which most probably has some bug because of which few modems don’t get recognized. ZTE AC2726, the modem which comes with PTCL EVDO, is one of the unfortunate ones. In a previous post we have covered how to connect to PTCL EVDO in Ubuntu 9.10. If you have Ubuntu 10.04 or later you can use the following procedure to connect to PTCL EVDO.
Install usb_modeswitch using the following command:
- sudo apt-get install usb-modeswitch usb-modeswitch-data
after installing usb_modeswitch plug your modem in. If your modem is already plugged in remove it and then plug it back in. Now use lsusb command to see if your modem is properly recognized. The output should contain a line like:
Bus xxx Device xxx: ID 19d2:fff1 ONDA Communication S.p.A.
Now go to System->Preferences->Network Connections. Click on Mobile Broadband Tab.
Now click Add. In the new window that appears, you will have ZTE device already selected.
In the new Window enter firstname.lastname@example.org as user name and ptcl as password and click apply.
You are all set. To connect to this connection click on Network Manager icon in Taskbar. Select this newly created connection and click connect.
