I have a huawei ec1561 broadband data card, ISP-MTS India. I am not able to connect internet through it. while connecting it via network manager it says "You are registered with home network" and again "Modem network disconnected" . i think it is detected as a modem but not connecting properly. Any help please? I'm hitting this rock with my head more than a month...

when I tried installing the driver that came with the device it finally says "Installing NDIS driver failed". I can post further information if anybody helps

  3. Select existing connection, click on Edit
  4. Now goto mobile broadband tab. Provide user name [user name is - ] and password [password is - mts] if not given already.
  5. Now try to connect, if same problem ouccures try the following
  6. Next go to "PPP settings tab" , in authentication click in "configure methods". Check only "CHAPS"
  7. Compression: Be sure the following are ticked: Allow BSD data compression, Allow Deflate data compression and Use TCP header compression

If the above settings doesn't work, try with other authentication method.

Alternatively you can use wvdial. Please comment here if the above method doesn't work. Accept this as an answer if it worked.
