CDMA USB Modem how-to / FAQ
As the modem will not "autoinstall" any parameters you must first of all
get from the internet provider:
1. username
2. password
3. number to dial
You may or may not need the package "usb-modeswitch" installed. This
"switches" the usb from appearing as a disk to appearing as a modem. If
the modem appears as a disk on insert and it does not help to "eject"
it, try installing usb-modeswich.
There are 2 ways (that we are aware of) to get CDMA modems working:
1. NetworkManager, KNetworkManager or KDE Network Manager widget
depending on system setup
2. command line wvdial
If you are lucky the usb modem is recognised on insert and shows up in
the network manager as a "mobile broadband" device. In that case, simply
fill in the necessary parameters (number to dial, username, password)
and then connect.
If it does not (can take up to 10 seconds) try these steps:
1. Open a command line console
2. type command "dmesg" and look at the output. It should mention a
"GSM-modem" somewhere at then connected to something like /dev/ttyUSB0
or USB1 up to USB3
If NOT try installing the usb-modeswitch package with your favourite
package installer. Once that is done reinsert the USB modem
If it now shows up in dmesg as a GSM-modem you are almost there. If not
- I suggest you try another one...
You can also look at the output from "lsusb" and see if/what the usb
modem is identified as
Once it shows up as a GSM-modem it might then show up as a "mobile
broadband" in your network manager.
If NOT install the wvdial package using your favourite package manager
After that from commandline run "sudo wvdialconf"
it should find the modem. Then edit /etc/wvdial.conf to something like
below:
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttyUSB0 (or what wvdial gives here, you might have to try
USB0 up to USB2 before it connects)
ISDN = 0
Phone = #777 (replace with number from your provider)
Password = what the provider gave you
Username = what the provider gave you
then to connect run "sudo wvdial" from command line to connect
