Huawei E1550

Hi, Am pulling my hair out with this modem not working under mandriva 2010.2 distro. Am trying to get the modem to work.

It does detect the modem, and you can see it in the network manager, but when you click on it, it asks you for the pin, which is normal, then you put the pin number in and then after a while the network center just says please make sure that the sim card is inserted?? It just does not seem to be able to get passed the pin code input.

Anyone else had this problem?

For the past few weeks I have been living in a remote area of the Philippines where the only option for internet connectivity is the mobile broadband service provided by a local cell-phone company (Huawei Mobile E158). As you, I have been pulling at my hair (and I donít have much hair left!) for the past few days attempting to get connected through my Linux OS, Mandriva 2010. I will here relate, in general terms, my ultimately successful experience.

First, I discovered I needed additional software. Fortunately, a friend had a Win7-based machine on which I downloaded rpm versions (and subsequently installed from a thumb-drive to Mandriva) of: COMGT; LIBPCAP0; & PPP. Additionally, but perhaps unnecessarily: KPPP; KPPP-PROVIDER; AND USB-MODSWITCH.

Second, the following website was extremely helpful, especially in setting up the broadband usb drive to behave as a modem only:

Third, I had to specify dev/ttyUSB0 and setup Analog Telephone Modem (POTS) (pppO).

Now I am able to connect, as root, at my machineís Network and Internet Connection Management icon (right click).

Wishing you the best, ~rc

Hi, many thanks for your reply and links. I have managed to find a way round the problem. I found out that there is a bug in the usb_modeswitch 1.1.1 package that is installed with mandriva 2010. So the way round this i found was like this and this works everytime. Is a bit longer, but at least it works.

Have to insert modem, and wait for it to be recognized, then launch a terminal and change to SU and type the following command:

usb_modeswitch -H 12d1:140c -v 12d1 -p 140c -R -V 12d1 -p 1446

that then switches the device to use the 1446 driver, then i click on the network center and click on the huawei modem and then the password prompt comes up and then click ok and then wait until the connect button comes up and click connect.
