 * [http://bitubique.com/content/view/26/42/ Getting Nokia 6630 / Nokia 6680 / Nokia N70 to work as 3G / EDGE / GPRS modem in Linux].

The following cards/phones works 100% with next scripts/configs:

  • Novatel U630
  • Option Fusion
  • Option Quad
  • Motorola E1000
  • Nokia 6680 (just don't set the speed/service - no 3gonly and 384k configs)
  • Option HSDPA Card
  • Novatel HSDPA Card
  • Huawei E620
  • ["Huawei E220"]

See ["3G_modem/cards"].

You need to download the new wvdial.conf for the ["HSDPA"] stuff to work !!!

This was originally written for ["Gentoo"] Linux which compiles everything from source. As a result of things might be a bit different, but we can work around it. Firstly, we need to get Linux to detect your card, start your PCMCIA services - normally this can be done using (most distros do this for you):

Code: /etc/init.d/pcmcia start Before you insert your card, open a console/switch to an open console and as root run the following

Code: tail -f /var/log/messages This will allow you to "see" what Linux is doing

Right, now insert your card and you should see some stuff happening. I have included log traces of what the two cards "look" like under /var/log/messages in the attachment section.

If you see only the option_insert_nousb.txt messages using an option card run the following command:

Code: modprobe usbserial vendor=0x0af0 product=0x5000 If you had to run the above command, you will need to save the vmc_g file attached into /etc/modules.d

Now we need to find out where your card is - you will see in the messages where the card is - /dev/ttyS? for novatel or /dev/ttyUSB? for option

Code: find /dev/ | grep ttySShould show /dev/ttyS0 or /dev/ttyS1 for a Novatel Card.

Code: find /dev/ | grep ttyUSBShould show /dev/ttyUSB0 and USB1 and USB2 for an Option Card. (or /dev/tts/ttyUSB0-2 for udev)

Once we found that, we need to change /etc/wvdial.conf to match your settings, attached is my working wvdial.conf. Now we can start dialing up

For Novatel:

Code: ["wvdial"] novatel internet 3gonly 384kFor Option:

Code: wvdial option internet 3gonly 384kIf you need to send your PIN, add "pin" infront of all the commands, e.g.

Code: wvdial pin novatel internet 3gonly 384kOnce your connection is up - surf away Now you can setup things like KPPP and Gnome's Modem Lights to do your dialing for you.

Extra Steps for the HSDPA card:

Download the kernel module from the link below. Extract it to a directory somewhere safe. If you are *still* running the 2.4 series of kernels, you need to change the Makefile to reflect this.

Compile the driver using the following commands:

Code: make clean && makeOnce this is done, run the following command to insert the module into the kernel

Code: insmod nozomi.ko (2.6 Kernel) insmod nozomi.o (2.4 Kernel)Once you have done that, use the following command to setup the connection:

Code: wvdial hsdpa Extra steps for the Novatel U740 Card

Until I get time to update the files etc. our Novatel Linux Users out there can just type this command before using the normal dialing command:

Code: ["modprobe"] ["usbserial"] vendor=0x1410 product=0x1400OR

Code: modprobe usbserial vendor=0x1410 product=0x1410 Using ["lsusb"] will show you the Vendor and Product ID's or cat /proc/bus/usb/devices will do the same.I will still add them into the FAQ but atleast this should help for now

This will add the USB's like the 3G Option did - am I seeing a swap here ? - so just dial /dev/ttyUSB0 or so - check the logs

Extra Steps for the Huawei Cards:

None really - just make sure usbserial is loaded and the card will come up on /dev/ttyUSB0 - check the logs again to confirm

If the card doesn't come up, unload usbserial and reload with the following command:

Code: rmmod usbserial && modprobe usbserial vendor=0x12d1 product=0x1001 I am still trying to work on the USB only card, so at the moment, I don't know if it will work under Linux.

Huawei E220:

I have found that this modem will only work with the short cable supplied...not the long one with two plugs...*shrug*

Same as the E620, except use the following modprobe command:

Code: rmmod usb-storage modprobe usbserial vendor=0x12d1 product=0x1003 (Some have reported an ID of 0x1001 - use lsusb to confirm) After that, you will notice only one USB serial coming up, then, remove the device and re-attach it, you shouldn't need to re-insert usbserial.

Notes:

I have only seen 3G speeds on this device, but I think it is because of my RF conditions and location. More on this to follow...

FAQ

Q) How do I enable "Internet Connection Sharing"

A) Since the 2.6 kernel is main stream etc. I will only cover IPTables and Kernel 2.6. I am also assuming that ppp0 is your dialup and eth0 is your lan

Firstly - we need to add some rules to iptables - run the following commands:

["iptables"] -F (This will CLEAR ALL RULES !!!) iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

then we need to enable routing: echo "1" > /proc/sys/net/ipv4/ip_forward

That should do it - from here you can add rules to block incomming connections etc.

Q) My card is broken/replies "ERROR" to all the commands

A) You didn't send your PIN to the card - either add the "pin" command or disable the PIN on the SIM

Q) My Novatel card is very slow - +-800 bytes per second

A) Try running "setserial -a /dev/ttyS1 low_latency spd_warp" - replace /dev/ttyS1 with your port Once you have your setserial command, insert it into /etc/ppp/ip-up.local - this will cause the command to be ran everytime a connection is made.

Q) What does all the wvdial sections do/mean?

A)

Defaults - What to do if nothing is selected (Always included) pin - send your pin to the card novatel - select the novatel card option - select the option card hsdpa - Option HSDPA card e1000 - select the E1000 via USB onboard - select the onboard modem of my notebook internet - select the internet APN internetvpn - select the internetvpn APN myapn - select your apn 384k,144k,64k - select the speed of your 3G connection 2gonly - select GPRS only 3gonly - select 3G only

Q) How do I see the usage under Linux

A) Linux Usage

TODO:

  • Make the Option card call "modprobe usbserial" by itself
  • Make the Novatel card register the second port under Linux
  • Do some research into the signal levels reported via +CSQ
  • Get the PIN to work with wvdial and Novatel
