This post is been migrated to – INITCRON.org


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.

Look and feel of ubuntu studio is very attractive. Folks who are not much interested in studio tools, but like the look and feel of it, can  stillinstall and use ubuntu studio theme on top of their existing ubuntu system ( sudo apt-get install -yq ubuntustudio-look ).

Ubuntu Studio comes with a kernel which is been  tweaked to allow higher priority to graphics, audio  and video applications which should give effectively better performance for these applications and reduce latency, jitter etc. Ubuntu Studio comes with Some of the tools that come with ubuntu studio are,

Linux on slow computers Episode 2

The 2nd experiment that I did was install Xubuntu 8.04 Hardy Heron on my Pentium 3 256MB Ram. Comparatively to Vector Linux Standard Edition(XFCE), I liked Xubuntu better as to add/install softwares were easier and spiced up with graphics compared to Vector Linux which looked plain and old.

Speed was almost the same at first, but after I’ve downloaded and installed the softwares I needed to run on the computer (eg. Open Office, Mplayer and so on), it was slightly slower compared to Vector Linux. That’s the price we pay for graphics I guess. Overall, I would choose Vector Linux as it was faster but wait…. when I installed Vector Linux on my computer, I logged in using a different desktop environment which was Fluxbox. It was way faster and not bad looking. It will be hard at first to get used to it, but I do enjoy the speed and the graphics are ok. It has the AWN kind of dock or a dock like MAC, not exactly the same but almost and it is fast not slow like AWN.

I guess the nest would be Linux Mint(fluxbox) and Fluxbuntu. Why? It’s because it is based on Ubuntu so that means it would be easier to handle compared to Slackware and others which most people don’t want to learn. If you’re more into technology then you should try out something harder like downloading debian, gentoo, slackware or any other major distros and start from the basics.
