[Solved] [now truly solved ;)] nm-applet doesn't show usb-3g-modem

Hello everyone!

First of all: I've used this very modem (huawei e173) for many years *successfully* under _all_ of my arch systems now. On the first installs I had to manually help it, but during the last 2 years there never was a single problem with the device or arch.

Now I've had to wipe both, my desktop machine and my netbook and start over. I decided to go with Plasma as my DE now and I got everything working. Everything? No! The modem won't work, no matter what I try!

To clarify: I'm using NetworkManager and ModemManager, both services are started!

lsusb output:

$ lsusb | grep Huawei
Bus 002 Device 003: ID 12d1:1436 Huawei Technologies Co., Ltd. E173 3G Modem (modem-mode)

As you can see, the modem is in modem mode!

Also, if I plug in the modem the icon for mobile internet appears in the nm-applet, but the modem itself doesn't show up under connections.

[b]systemctl status ModemManager[/b]

Mär 12 22:07:21 mypc ModemManager[329]: <info>  Modem /org/freedesktop/ModemManager1/Modem/0: state changed (enabling -> registered)

Do you have any idea what could be the cause of this? Before I primarily used gnome and never had a problem at all. Could it be due to nm-applet?

Kindest regards,
Humar

So, as far as I understand its wrong that it changes the value

12d1:1446

(which stands for "storage")

to

12d1:1436 

I tried to fix it like so: http://www.draisberghof.de/usb_modeswit … php?p=4521

No luck. Still changing to 1436

New modemmanager version did not fix this for me.

If you need any more logs or anything, just ask. I'm getting desperate here. I really need that 3g modem!

Humar,

I'm not certain that the 1436/1446 issue is still live. What seems to be the relevant file (12d1-1446) used by the PKGBUILD for usb_modeswitch 2.2.1-1 seems to include 1436 in the "TargeProductList" array:

# Huawei, newer modems, and rebrandings
TargetVendor=0x12d1
TargetProductList="1001,1404,1406,140b,140c,1412,1417,141b,1429,1432,1433,1436,14ac,1506,150c,1511"
HuaweiNewMode=1

You don't have netctl running as well? (That always seems to happen to people.) Here is a useful article on debugging nm and mm, which you might want to follow:

Nah, I don't have netctl running and I debugged to no avail. Everything seems right. It just doesn't show up in the applet. (Although the "3g icon" appears, I have no modem-device available there).

Maybe I'll try out gnome again. It could be a problem with plasma, although that's highly unlikely, as I used both, Gnome and Plasma beforehand. (But gnome was always there first, so...)

Yep, it really was/is Plasma. It works like a charm with cinnamon (2.0)!

I configured the stick there (in the gui) and it now runs perfectly under plasma -.-

What a stupid problem!

edit:

Other way to fix this, install

mobile-broadband-provider-info

package and add the mobile internet through nm-applet. Works like a charm as well. Sadly this is no dependency and I had to figure that out by myself -.-
