Setting up the Reliance ZTE MG 880 USB data card on Ubuntu 8.10, Intrepid Ibex

Firstly plug in the USB Modem.

Then in a terminal type  cat /proc/bus/usb/devices |grep ZTE -B1

Look for  the Vendor id & Product id.

In my case :

P:  Vendor=19d2 ProdID=fffd Rev= 0.00
S:  Manufacturer=ZTE, Incorporated
S:  Product=ZTE CDMA Tech

Add the following line to /etc/modules* (you will need admin rights to do this  e.g. sudo nano /etc/modules)

and add this line to the end of the file on a new line.

usbserial vendor=0x19d2 product=0xfffd

where  19d2 is my vendor id and fffd is my Product id (Replace it with the values you got from running cat /proc/bus/usb/devices)

To configure wvdial, type sudo wvdialconf It should show you that it has detected a modem at the end of the commands output. (If you don’t have wvdial do a sudo apt-get install wvdial -You need to be online to do this)

next edit /etc/wvdial.conf (sudo nano /etc/wvdial.conf)

Copy and paste the following lines into your wvdial.conf

Note: If you are copying and pasting, the quotes will get mangled and you will need to delete and renter all the quotes/comma’s

[Dialer Defaults]
Init1 = ATZ

Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Phone = #777
Username = 9310xxxxxx
Password = 9310xxxxxx
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Set Volume = 0
FlowControl = Hardware (CRTSCTS)
Modem = /dev/ttyUSB0
Dial Command = ATDT
Baud = 460800
Stupid Mode = 1

Now replace the 9310xxxxxx in username and password with the Reliance number of your data card. Also replace ttyUSB0 with the device name that wvdialconf detected.

Now you can connect by opening a terminal and typing in wvdial from the terminal. If you get any permission errors, try sudo wvdial. On some somputers it works without sudo, on some others, I need to use sudo to connect. I haven’t been able to figure out the cause for this yet.
