Biggest nightmare of Windows is back with its blazzing internet speed

I switched from traditional windows to ubuntu because of many reasons but the most important was its security from various types of viruses and also because of its internet speed. While former remains the same in ubuntu 11.04 (Natty Narwhal) , latter was absent. And this was not the problem with me indeed i found many forums in which all newbies to ubuntu 11.04 complained about the same problem. The net speed is very slow slower than in windows... a big reason to worry. In earlier versions of ubuntu, the great internet speed was the main advantage but this is not the same with this 11.04 version. So i finally figured out what was the thing going on behind the scene that was responsible for this great damage. It is this new Power Management settings in ubuntu 11.04(NattyNarwhal) that is causing less power to be supplied to the wireless internet device which is responsible for the slower internet speed. So to overcome this problem we are going to turn off power management by ubuntu for wireless internet device by following the following steps................
firstly go to File System and check whether the path etc/pm/power.d is present or not..
if its not present then you have to make this directory structure using mkdir
now if its present then follow the given steps-
1. Open the terminal and type sudo gedit /etc/pm/power.d/wireless
2. Enter your password. A gedit window titled wireless will pop up. Most probably it would be blank and you would see an empty document.
3. Now just add these lines to the empty document
#!/bin/sh
/sbin/iwconfig wlan0 power off
4. Save the document and close it and close the terminal window.
5. Now simply reboot your system and you are done.
And now your favourite ubuntu is back with its blazzing internet speed.

By the way, i dont like the new Unity interface in Ubuntu 11.04 and reverted it back to the classic GNOME by following these steps-
1. In your login screen while you enter your password just see below, you would observe Ubuntu written with a small arrow beside it,
2. Just click on the arrow and from the pop up list just select Ubuntu Classic .
3. Now enter your password and login and you would get your old Ubuntu look back.
Hope you will enjoy this post !!!!!

Installing Ubuntu on your computer

There are two ways of installing Ubuntu on your computer. First is within windows and other is alongside with windows. By first method, ubuntu will be installed as if we are installing some third party software within windows reserving around 17 Gb of space for it. If you are new to ubuntu then its the best way for trying your hands on ubuntu. Just download the latest version of Ubuntu from www.ubuntu.com. Then burn it on a CD and run this CD. Then just click on it and click on Install Within Windows option. But if you have already used it before like me and know about it (a little bit) then just install it alongside with windows. Firstly i would like to tell you that installation of Ubuntu is a little bit differnt than windows. In windows we can install it at a particular partition already created (like suppose windows 7 home basic is installed at C drive of your computer and you want to change it to Ultimate then you can simply select C drive while booting from the Ultimate CD (while its asking where u want to install) and it will format your C drive and Home Basic will be removed and Ultimate will be installed). Before installing ubuntu i created a partition of size 30 Gb and thought of installing of ubuntu at this partition but to my surprise while going through the installation process it didn't worked like i thought. So simply left about 20 Gb of space unallocated (by unallocated i mean that, this 20 Gb is not made any new partition). Then while going through the installation process the time when it asks whether u want to install ubuntu with windows or without windows just choose Something Else. Now u will see something not so eye pleasing. Just select the free space and click on Add below. Then in the pop up window, choose file system as Ext3 mount point as /boot check the format check box and allocate 300 Mb for it. The rest partitions are-
1. Mount point as "/" "Ext3" "7Gb"
2. File system as "Swap" "4Gb" and no mount point
3. At last mount point as "/home" "Ext3" and allocate it all the remaining size.
Finally click on Install Now and complete the installation process.
