Support for BSNL 3G (Teracom USB devices)

[Amit Mendapara]

Binary package hint: usb-modeswitch-data

I have added support for Teracom HSDPA datacard distributed by BSNL. Here I am attaching the patch against the recent upstream revision.

[Amit Mendapara (cristatus)]

This patch is tested with Teracom (Linktop / LW273) usb datacard. I am not sure about LW272 model though.

[Mandar Vaze (mandarvaze)]

Tested this patch with LW272 - works.

[Amit Mendapara (cristatus)]

The patch works with both Linktop/LW272 and Linktop/LW273 distributed by BSNL.

[Bhavani Shankar (bhavi)]

Same here

regards

[Amit Mendapara (cristatus)]

Here is the lsusb output.

[Amit Mendapara (cristatus)]

And here is for LW272. The previous one is for LW273 and both are identical.

[nagaraj (hamlet32)]

hi, i too have a detection problem with teracom lw272. how do i use/apply this patch to usb_modeswitch?
thanks

[nagaraj (hamlet32)]

sorry, forgot to attatch lsusb.txt

The patch is already accepted upstream. You can get upstream copy using git as:

git clone git://git.debian.org/collab-maint/usb-modeswitch.git
git clone git://git.debian.org/collab-maint/usb-modeswitch-data.git
git clone git://git.gnome.org/mobile-broadband-provider-info

Also, try the latest versions of ModemManager and NetworkManager from the NetworkManager daily PPA (https://launchpad.net/~network-manager/+archive/trunk) for better experience. I have implemented ModemManager driver for Linktop devices which is accepted upstream.

sudo add-apt-repository ppa:network-manager/trunk
sudo update
sudo upgrade

Then restart your computer and enjoy!

[nagaraj (hamlet32)]

thanks,
but no luck for me,
my comp refuses to show the modem. i ran all the commands above and did what the tweaking you have suggested in http://amit-mendapara.blogspot.com/2010/11/amazing-bsnl-3g.html. still no luck. any suggsetions?
one more thing sudo update and sudo upgrade did not work for me. had to 'sudo apt-get update' and 'sudo apt-get upgrade'.
waiting for your response.

[Amit Mendapara (cristatus)]

Oh, sorry. The commands should be:

sudo apt-get update
sudo apt-get upgrade

BTW, both the models are reported working well with these updates. Would you attach few more information here? Please, don't paste the output but attach txt files of the output of following commands:

sudo lsusb -v > ~/Desktop/lsusb.txt
sudo usb-devices > ~/Desktop/usb-devices.txt

After issuing `usb_modeswitch -v 230d -p 0001 -u 3` command, run the `usb-devices` again.

sudo usb-devices > ~/Desktop/usb-devices-2.txt

Thanks

[Amit Mendapara (cristatus)]

I have backported the latest upstream version of usb_modeswitch to Ubuntu Maverick (10.10). You can find the packages with this PPA (https://launchpad.net/~cristatus/+archive/nm-ppa).

[nagaraj (hamlet32)]

added your ppa. now the network manager simply returns 'gsm network disconnected' after connecting the modem. i am attaching the response to usb_modeswitch -v 230d -p 0001 -u 3
Looking for default devices ...
 Found devices in default mode or class (1)
Accessing device 000 on bus 001 ...
Getting the current device configuration ...
Error: getting the current configuration failed (error -1). Aborting.

and 'sudo usb-devices > ~/Desktop/usb-devices-2.txt' returned

/usr/bin/usb-devices: line 79: printf: 08: invalid octal number
/usr/bin/usb-devices: line 79: printf: 09: invalid octal number.

i am attatching the lsusb.txt and usb-devices.txt

these were all run while the teracom modem was connected and the red LED was flashing

[Amit Mendapara (cristatus)]

After looking at your usb-devices-2.txt, I confirm it's switched successfully and now it should work without any issue. That error stating `Error: getting the current configuration failed (error -1). Aborting.` seems to be from the latest changes in usb_modeswitch package but just ignore them.

[nagaraj (hamlet32)]

thanks a lot, it seems to be working now. though few strange things happened initially -the first couple of times it would try to connect and then stop recognising the modem. then i tried using my airtel sim (gprs) with teracom modem amd it connected alright without any problems. i tried again with bsnl 3g sim but it failed. after a couple of atempts it connectd and is working now. i dont understand the strange behaviour, but i am happy that it is working. thanks a lot for your prompt help and assistance.

[nagaraj (hamlet32)]

hi amit,
i am back here again with more troubles.
the teracom modem worked well for 2days and then again it was back to its adamant behaviour. the modem is not seen at all and althouigh everytime i re plug the modem in, the network manager strts searching but fails to register anything. how do i use the modem manger and network manager as suggested in your post #10 above?

[Amit Mendapara (cristatus)]

nagraj,

It could be due to service outage in your area. I am seeing frequent disconnection problem here (device disconnects regularly on 250mb of data usages). BTW, follow this guide (https://wiki.ubuntu.com/DebuggingNetworkManager) and attach the debug info here.

[nagaraj (hamlet32)]

i need help on the following to use the debugging network manager guide -
i am supposed to run " sudo modprobe -r DRIVER" but i dont know what the driver is. "sudo modprobe -r" returned a lot of options, which i could not understand.
in the paragraph on debugging 3G, i need to run "$ /lib/udev/nm-modem-probe --verbose --export /sys/class/tty/ttyUSB" or "$ /lib/udev/nm-modem-probe --verbose --export /sys/class/tty/ttyACM" , both return "command not found".
other things i tried are - i inserted the 3G sim to my mobile (nokia E62) to check signals and signals are quite fine.
i added the daily update ppa from 'network manager' page (https://launchpad.net/~network-manager/+archive/trunk); it did not make any difference!
another thing i have noticed is, i also have a wireless router connected to an adsl modem ( bsnl broadband) connects through 'auto eth0', which of course is the default connection. when i have 'auto eth0' active and connect the 3G modem, the network manager detects it and connects but i cant use that connection. the moment i disconnect 'auto eth0' the 3G connection also drops.

plese let me know how to find out what driver is installed and i will post the result of "sudo modprob -r DRIVER".
thanks a lot
nagaraj

[nagaraj (hamlet32)]

forgot to mention one more thing.
is there any way of using wireless router so that other computers can connect to the network wirelessly and can use the internet connection of 3Gmodem ( that is if at all it starts functioning). in other words is there anything like 'share this internet connection'?
thanks amit

[Amit Mendapara (cristatus)]

nagaraj,

See the notes on that page. I actually forgotten to mention (https://wiki.ubuntu.com/DebuggingModemmanager). That modprobe stuff was required with old NetwormManager 0.7 release.

FYI, with this and other related fixes (available via my network manager ppa), my LW273 device is working perfect.

BTW, you can share your internet connection by creating ad-hoc wifi connection if your wireless adapter supports it else you should try with any wifi router that supports OpenWRT or dd-wrt firmware. There are also few models available in market with built in 3G SIM slot.

[nagaraj (hamlet32)]

i ran the debuggingmodemmanager commands and got the following logs (attatchments)

[nagaraj (hamlet32)]

and this. on running the last command 'sudo NetworkManager --no-daemon 2>&1 | tee /tmp/nm.log.txt' to restart nm and to save the log files, the network manager restarted and now it detects my teracom modem and connects but it is not connecting to my wired connection 'auto eth0'.

[nagaraj (hamlet32)]

forgot to mention - now my bsnl 3g connection is displayed as 'bsnl connection1 (BSNL/cellone HSDPA). hopefully this will stay. but i also need to connect to my auto eth0.
thank you so much. let me know if the log files mean anything.

[nagaraj (hamlet32)]

i rebooted and tested again- my network manager shows both auto eth0 and bsnl 3g as available but connects only to bsnl 3g now and does not connect to auto eth0. have i fired some conf files in the process?
thanks for your patience and help.

[Amit Mendapara (cristatus)]

Nagaraj,

Looking at your logs, I am sure your BSNL 3G connection is now working
however I am not sure about the issue with your eth0 (wireline connection).

BTW, I have used wireline connection along with my BSNL EVDO connection
previously (with multihoming). So it should work with 3G also.

sorry,
you must be wondering where have i disappeared. no secret - both my internet accesses had stopped working ( auto eth0 and bsnl 3g) when i tried to correct the isssue of 'auto eth0 disconnect'. tried various things but nothing seemed to work. realised for the frst time how difficult it gets if one is cut off from the net . finally did a clean reinstallation of maverick to get the broadband working. (3g still not working) again went through your bug fix and added your ppa and ran in debugging mode but it did not work. but the same actions have made my laptop ( again maverick) recognise and connect through bsnl 3g. thanks a lot for all your help. looks like i will leave at it. just wanted to let you know what happened. regards and thanks again.

[Amit Mendapara (cristatus)]

Nagajar,

I just fixed few more bugs (reported upstream) in modem-manager and uploaded
the patched version to my ppa. Now my LW273 modem is working like a charm.
Try upgrading to the latest version from my ppa. BTW, I am not sure what's
happening in your case but I haven't faced any such issue since I started
using this device.
