Can't connect to HSDPA modem

Hi all,

I'm new to Arch Linux and this Forum.

I recently installed Arch + KDE. But I have noticed that I can connect to Internet via LAN (Ethernet), but not from HSDPA Modem.

When I run lsusb or usb-devices, it shows my modem. And NetworkManager and ModemManager is also running. When I try to create a new profile using Network Manager Applet, I can select the device (Huawei E176), but when I click next, the GUI dissapears and then nothing happens. I don't have an Ethernet or Wi-Fi connection at my home.

Please help me.

Run nm-applet in a terminal and see where it goes wrong. Or try wvdial.

Re: Can't connect to HSDPA modem

Thank you for your quick response.

I was using KDE. hence only had kdeplasma-applets-networkmanagement. So I didn't have nm-applet installed (which is intended for Gnome, if I'm not wrong). But as you said, I installed it anyway, and now everything is working fine..!

It installed libnm-gtk-0.9.10.0-2,  libsecret-0.18-1,  mobile-broadband-provider-info-20120614-2 and  network-manager-applet-0.9.10.0-2 and however it started working fine. I have no clue how.

Anyway, thanks for the help.

EDIT : Not solved.

Re: Can't connect to HSDPA modem

Hi again,

I'm really sorry, I was really trilled when it worked, at least for one time. After I reboot, the same problem is there. Now, even tough I run nm-applet and try to connect from it, it gives me an error.

(nm-applet:1183): nm-applet-WARNING **: Cannot grab information for modem at /org/freedesktop/ModemManager1/Modem/0: No ModemManager support

At some tries, it just runs and when I tried to connect, it won't (without giving any error.).

And now I'm stuck..

Re: Can't connect to HSDPA modem

^ Ok, at least now we have a clue. Check the status of the respective services:

systemctl status ModemManager
systemctl status NetworkManager

Both of those services are up and running.

Re: Can't connect to HSDPA modem

Hi again,

I noticed that, ability to connect via my HSDPA modem seems random, after reboot. Sometimes I can, like at this moment. But many of the times I can't. I don't know what is wrong with my installation.

Re: Can't connect to HSDPA modem

Try following instructions here for the ModemManager service:

https://wiki.archlinux.org/index.php/Sy … ic_service

Sounds like some race condition to me, maybe with a kernel module?
