problems with next G setup

[crutch52]

This is a copy of a question I posted at linuxquestions.org

Hi, I've been trying to connect to to a wireless internet sevice using a sierra airprime 880U card on Arch linux. the card seems to be recognised OK but any attempt to connect ends with the modem hanging up.

I'm trying to use wvdial but have not had any more luck with pppd or kppp. My config file for wvdial is

[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Phone = *99#1
ISDN = 0
Username = ***********
Init1 = ATZ
Password = *******
Modem = /dev/ttyUSB0
Baud = 9600

(note i've removed my username and password for this)

Initially when I start my computer I have problems with the ppp daemon
(This could well be the source of my problem but I don't really understand this) this is best illustrated using pppd

[bruce@crutch etc]$ sudo pppd call gsm
Password:
pppd: pppd is unable to open the /dev/ppp device.
You need to create the /dev/ppp device node by
executing the following command as root:
mknod /dev/ppp c 108 0

Running this command seems to help but I still get the modem hanging up

[bruce@crutch etc]$ sudo wvdial

And this carries on untill I abort the process.

Can someone please explain some of this? I'm stuck using other peoples internet until I can get this working

I found a How-To on getting an E-Plus UTMTS/HSUPA card recognized in Linux. I know it is a different card, but if you're lucky the process may just work for your card.

Linux with UMTS HSUPA ExpressCard - Perimeterless Network

With the card plugged in, enter this command.

cat /proc/bus/usb/devices

Find the card in the list. Copy the information from these three lines. You can post it here too.

P:  Vendor=  ProdID=  Rev=
S:  Manufacturer=
S:  Product=

You could enter that info when the module is loaded, but first you need to unload the module.

modprobe -r usbserial

Then reload it with the info obtained about the card.

modprobe usbserial vendor=<info here> product=<info here>

I don't know if this will actually work, I never ran modprobe with options before. If it does work, you can then add it to your modprobe file.

It has been a very long time since I have used Dial-up Internet but I seem to remember having a similar problem. Everything looked good until it tried to connect, then it just died. My problem was that I had the modem dialing the wrong number to my ISP. So make sure that the number you are dialing is correct. (Yes I know this is dumb)

Thanks guys,
I'll see what I can make of what you've given me.
