Mobile broadband without networkmanager

pbneves · 10-03-2014, 01:40 PM

I have a laptop with a sierra wireless (1199:9041) 3g modem that works ok with network manager, and when it is working there aren't ppp or wvdial services running, and i have a wwan0 card running and with active ipv4.
The problem is that networkmanager puts eth0 down and i need both cards running so i can configure the correct network routing.
How can i configure and make the mobile broadband connection through console without using networkmanager?
Where can i read more things about this?
Thanks in advance.

Hi,

If you are talking about using a manual network setup then look at: Slackware Doc Project

I use pppd.

IIRC, I used pppsetup to do the spadework, then edited /etc/ppp/options with the correct device, as the only problem was that /dev/ttyUSB0 didn't feature in the list. When you plug in your mobile device, dmesg should tell you what it is.

FWIW here are my files:

/etc/ppp/pppscript

Code:

TIMEOUT 60
ABORT ERROR
ABORT BUSY
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
"" "AT&FH0"
OK "atdt*99***1#" #number to dial
TIMEOUT 75
CONNECT

/etc/ppp/options

Code:

lock
defaultroute
noipdefault
modem
/dev/ttyUSB0 #mobile broadband adapter device
460800
crtscts
passive
asyncmap 0
name "user"

Your mobile provider may require a username and password; I don't think it matters what it is on my network so I just use PAP authentication with "user" and "pass":

/etc/ppp/pap-secrets

Code:

"user"   *   "pass"

So, from any virtual terminal I can do (as root): "ppp-go" to connect, "ppp-off" to disconnect.

Maybe i was misunderstood

My main question is how to deal with direct ip modems. My device is located at /dev/cdc-wm0 and not at /dev/ttyACM0 or /dev/USB0, so i believe when it is in use with networkmanager it doesn't use wvdial and ppp, because it creates the network interface wwan0.
The modem in my laptop is a built in one.

So what is the output of "ifconfig wwan0" after you've done "ifconfig wwan0 up" ?

Here it is

wwan0: flags=4291<UP,BROADCAST,RUNNING,NOARP,MULTICAST> mtu 1500

Thanks.

It seams that the problem was using the nm-applet!
Using "nmcli c up id Vod" started the 3g connection and permitted the eth0 network card being running and define the ip route rules correctly.
When using nm-applet only one connection is active at the same time.
Thanks all for your help
