Hi! I try to set up a mobile broadband in my opensuse 12.1. I am a beginner and have very little knowledge about linux. I have a USB modem, Huawei E1750. Is there any guide that I can use?
Hi seniorcoach
Just to start with, plug in your USB device, open a terminal and issue these commands
lsusb
ls -l /dev/ttyUSB*
dmesg|tail
Post the output (enclose between
and [/CO...] tags)Thank you! Are you saying that each commando should be written between the tags?
Excuse me! I misunderstood. This is the output when I run the commands.

Excuse me again! This will result with the correct tag.

It appears that your mobile broadband modem is recognised, and handled by the kernel properly. (The /dev/ttyUSB* device nodes are a good sign). Now, you need to configure via the network manager.
Ok, thank you! Can I use yast2?
I have chosen yast2 by default for the network setup. When I tried to switch to the network manager, I lost the wireless connection.

You’ll need to recreate the wireless connection, but it’s not hard. Read this guide about configuring with NM (slight differences between KDE and Gnome):
Thanks for your help! Change of network tools went well and the wireless connection is ok again. But the settings for mobile broadband want a username and password and there is nothing to get from my operator. How do I do?
It depends on your service provider, but for many, it is not necessary to supply a username or password. The SIM card essentially handles the security authentication.
For example, with my New Zealand XT mobile connection, I have only to define the following
Number=*99#
APN=internet.telecom.co.nz
When I click on Edit, I get up this message
showed, number = * 99 # and APN = online.telia.se APN, the system has found itself in the setting.
The picture was too big, but the text reads, No agents were available for this request

Hmmm…I haven’t experienced that error, but a bit of googling lead me to this possibility. Apparently, this error can happen when kwallet s not configured to manage your passwords (even with connections that are not using username/password authentication). Anyway, try the advice given here:
Chakra Linux – KDE – “No agents are available for this request” error
Now it works, but only if I have the box “Allow Roaming” checked. In the information box appears that I am connected to the wrong provider, Tele2 AB instead of Telia. But the ip address I get, is owned by Telia. But I have not yet tried your last advice!

Okay. That option doesn’t exist with the KDE config tool I’m using. That is a Gnome NM feature. I would be wary of allowing roaming (charges) though.
Maybe NM is having trouble connecting with your particular network.
I don’t think the kwallet advice is applicable to your situation, so don’t worry about it.
Maybe this explains the need to have ‘Allow Roaming’ checked
When PTS awarded four licenses for the 3rd generation mobile networks in December 2001, Tele2 was among the winners. Notably Telia, the former telephony incumbent in Sweden, did not receive a license and so an agreement was established to build a 3G network jointly by Tele2 and Telia using Tele2s license. SUNAB builds, owns and operates that 3G network.
That explains it all. Thank you so much for your help! I think I can drive on now without any problems!
