I have just bought an Huawei E1550 3G modem for use with 3 Ireland. I am trying to get it working with Kubuntu 9.10.
First of all, I manually created a new Mobile Broadband connection in Network Manager using variations of the following settings:
Then to get the kernel to recognize the modem, I issue the following:
Number: *99#, *99***1#
APN: 3internet, 3ireland, 3ireland.ie
(the values for vendor and product correspond to those output by lsusb)
sudo modprobe usbserial vendor=0x12d1 product=0x1001
Now, the NetworkManager icon turns into a mobile phone. So, I click on this and select the connection I created above. It appears to be doing something for about 5-10 seconds and then just stops without any information as to why. (When I roll over the icon, a tooltip pops up saying "Obtaining Network Address" and when I roll over the menu entry, a different one pops up with some more information including the message "Preparing to connect".)
The modem works fine in Windows (after the requisite software is installed), but I don't have Windows on my laptop (nor do I feel I should have to). I also tried using the modem in a Windows VM in VirtualBox, but it wasn't able to install the drivers for it unfortunately.
I tried it on Ubuntu 9.10 (on an eeePC) and it all works. The only difference I can see in the settings (between Ubuntu and Kubuntu) is that, in Gnome, I can set the IPv4 settings whereas this does not seem possible in KDE.
Is there any way to see what is actually going on in NetworkManager? (There don't appear to be any logs - at least not in /var/log.) Is there a command-line equivalent I can run to try to get some more information?
Or even better, has anyone had the same problem and been able to solve it?
