This howto explains steps to make Ubuntu 10.4 LTS codenamed “Lucid Lynx” detect, configure and install Huawei EC1262 usb modem used by Reliance Netconenct Broadband+.  This should also apply to various other similar devices used by Tata Photon, Alcatel, Vodaphone etc. 3G connections.

Solution:

Install

  1. usb-modswitch
  2. usb-modswitch-data

Two ways to do it,

  • Automatic from package manager, (Recommended)

Paste this to terminal (Applications=> Accessories=> Terminal)

sudo apt-get install -yq usb-modeswitch usb-modeswitch-data

  • Manual

1. Open a Terminal from  Applications=> Accessories=> Terminal

2. Download and install usb-modeswitch-data for both 32bit and 64bit,

wget -c  http://mirrors.kernel.org/ubuntu/pool/universe/u/usb-modeswitch-data/usb-modeswitch-data_20100127-1_all.deb

dpkg -i  usb-modeswitch-data_20100127-1_all.deb

3. Download and install usb-modswitch 

For 64 bit :

wget  -c  http://mirrors.kernel.org/ubuntu/pool/universe/u/usb-modeswitch/usb-modeswitch_1.1.0-2_amd64.deb

dpkg -i usb-modeswitch_1.1.0-2_amd64.deb

For 32 bit

wget -c http://mirrors.kernel.org/ubuntu/pool/universe/u/usb-modeswitch/usb-modeswitch_1.1.0-2_i386.deb

dpkg -i usb-modeswitch_1.1.0-2_i386.deb

Once you install both packages,  you should have the modem detected and then use networkmanager to configure it.

What does usb-modswitch do and why is it necessary?

USB devices, specially high speed wireless WAN dongles such as the Huawei Modem that comes with Reliance NEtconect Broadband+ is only detected as USB storage device by Ubuntu and not as a Serial Modem in order for it to function as one.  usb mode switch does the work of switching the mode to modem from the storage only modem and make it awailable to be used as a internet modem device.

In this article I am going to provide you a simple and quick way to setup reliance data card on ubuntu hardy heron. Most of the tasks could be done with the script that I am attaching here.

1. Plugin Data Card

Running Setup Script From a Terminal2. Download setup script from here. Open a terminal and run it as ” bash reliance_setup.sh “. It will ask for your data card connection number. Provide it when it does and press enter. The script will install gnome-ppp gui package, wvdial, and modify the necessary system files to setup permissions to dial the reliance connection using ppp.

3. Once set up, the script will launch gnome-ppp dialer. You need to provide following,

Username

Password (same as usrname. the connection number)

Phone Number : #777

4. Click on “Setup” option from the dialer window. From modem tab, click on “Detect” button which will automatically detect your usb modem in most cases. If not, you’ll have to choose it manually from the dropdown menu. Choose speed as 115200 from the drop down list.

5. You could leave rest of the options as it is for now. Close the setup window and click on “Connect”. You are all ready to rock. A connection window will appear, from which you could click on “Log” to see what is happening while connection is progress.

Are you tired of waiting till your favorite yououtube video stream is being buffered to avoid jitters?  Are you looking for an application to save youtube videos offline and watch them at your convenience
later? Do you want to save multiple parts of a video and watch it as a whole in one go? …. Try Miro.

Miro is an application which turns your computer into an internet TV video player. It has a concept of channels whereas viewers could browse through thousands of channels available and subscripbe to them and receive regular feeds downloaded at your desktop, some of the most popular being ‘National Geographic Video Shorts’, Discovery Channels Video Podcasts, Cartoons, Spanish Learning Channel etc.

Here are few interesting features available with Miro:

1. Watch YouTube Videos: One can search, download and watch YouTube videos and videos from maany more video streaming sites such as Google Videos, Yahoo Videos, Blogdigger, Blip.tv, DailyMotion. The application actually downloads the videos to harddisk, making it available to be watched offline. By default the video expires in 5 days, which can be changed with option to store it permanently on the drive.

2. Video Player: Miro also acts as a video player for the internet videos. It uses embedded player such as gstreamer, xine in linux and vlc on windows, and quicktime on Mac to play the videos. One could
actually watch videos in fullscreen mode, which apparently looks better than that watching it on youtube. And users could play videos, which generally come in the parts, as if it is a single video.

3. Cross Platform: Miro is a Open Source Software, released under GPL License, and is avaialble on Linux, Windows, and Mac Operating Systems.

4. Widely Supported Formats: Miro supports a wide range of video formats including MPEG, Quicktime, AVI, H,264, Divx, Windows Media, Flash Video(Youtube Videos) and many more.

6. Podcasts Compatible: You could add your podcasts that you have been downloading automatically with itunes so far, to Miro as a channel. Once added, all new podcasts can be downloaded automatically.

7. Share: Users could search videos, watch them and share with friends using social sites such as del.icio, digg, reddit etc.

Even though its released as a beta, overall, Miro is a wonderful app to have on your desktop.

How to install Broadcom BCM94311MCG WiFi Card on OpenSuse 10.3 using NDISWrapper

May 18, 2008 1 comment

This post is been migrated to – INITCRON.org

Here is a howto to install Broadcom  wireless card drivers on opensuse 10.3  using ndiswrpper and windows drivers. I installed  Broadcom Corporation BCM94311MCG wlan mini-PCI adapter on  Compaq Presario 3611AU. The process of Installing windows drivers on linux using ndiswrapper is more or less same for most of  the adapters.

  • Windows Drivers : You need to download download windows drivers to get started with. Windows XP drivers are generally safe to be used with ndiswrapper. I downloaded xp drivers for broadcom adapter from hp/compaq site. ftp://ftp.hp.com/pub/softpaq/sp36501-37000/sp36684.exe.
  • Extract the windows driver exe using cabextract. cabextract  sp36684.exe
  • Install ndiswrapper package using yast. This should be straight forward.
  • Unload the bcm43xx module.  rmmod bcm43xx
  • Load ndiswrapper using modprobe. modprobe  ndiswrapper
  • Load windows drivers extracted in step two. Load the .inf file using ndiswrapper.  ndiswrapper -i *.inf
  • Blacklist bcm43xx module, not to be loaded at boot.  echo “blacklist bcm43xx” >> /etc/modules.d/blacklist
  • Configure ndiswrapper to be loaded at the boot time.
