NextG on Linux

This is how I managed to connect to the Telstra HSDPA, (NextG) network on my Ubuntu Fiesty installation with a pcmcia Turbo Card, (ZTE MF332 3G). However I think it should work on any distro with the right packages installed.

• You need to create a nextg-chat file. Just make sure you put your pin in. Hereś what mine looks like.

• Here is a copy of my /etc/ppp/peers/nextg file

• Now I insert the card and discover the vendor and product ID. Using the lsusb command. Here is my output.

Bus 006 Device 118: ID 19d2:0001
Bus 006 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 005 Device 002: ID 0483:2016 SGS Thomson Microelectronics Fingerprint Reader
Bus 005 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

• Next I load the usbserial module using the following command, entering the ID from the lsusb output.

modprobe usbserial vendor=0x19d2 product=0x0001

• You should now be able to see the ports /dev/TTYusb0 etc
• Now create a soft link using the following command

ln -s /dev/ttyUSB0 /dev/modem

• Now make the connection using this command

pppd call nextg

• I use kppp and I had to muck around with the settings a bit. I needed to alter a few things like entering a static default gateway 10.64.64.73 , the phone number *99# and specifying authentication as PAP.
• Next I plan on automating all these processes. If you wish to try for yourself, below are all the links where I got the information to get this to work for me.
