Problems with WiFi on Ubuntu? We try to solve ...

In recent years we have seen that have been resolved several problems with hardware support, Because some companies have begun to drop support for Linux and the other due to the considerable brought improvements in Linux kernel.
However, not everything is solved are still people who find themselves post-installation problems with the graphics card, wireless, printer, etc.. Moreover, even if our hardware is detected is not guaranteed to work properly is the case of some WiFi cards but which are properly recognized, however, work very badly. Today is just an example of a netbook with this Wifi Realtek rtl8187b card well recognized but works very badly.

How can we solve these problems?

One of the main problems is due to energy savings, We set our Distribution WiFi card in a power saving mode we doing that works well just started and after a few minutes the connection is very slow.

Solving this problem is very simple, just start the terminal and type:
sudo gedit /etc/rc.local
and before the exit 0 command insert

iwconfig wlan0 rate 5.5M

save and reboot.

If we start ass Luckily our device and the connection is working properly.
If, however, still does not work we can choose use the Windows drivers through Ndiswrapper.

Ndiswrapper is a Linux kernel module with which we can install native drivers for Windows on Linux solving (but not always) some problems with our WiFi. To use easily Ndiswrapper we can use ndisgtk a simple GUI that allows us to install WiFi driver for Windows with great ease.

To install ndisgtk just go Ubuntu Software Center or from terminal type:

sudo apt-get install ndisgtk
and confirm.

Now we download the WiFi driver for Windows or insert the driver disk usually comes with the PC or device, and we start our ndisgtk and click Install New Driver and go into the folder contains the drivers and try the file . Inf Once entered click on Apply to install the driver.
Once installed the drivers we start the terminal and check if our driver has been installed correctly by typing:
ndiswrapper -l
If everything is correct you should see a written as:
Installed ndis drivers:
[driver name] driver present, hardware present
now increasingly from a terminal type:
sudo ndiswrapper -m
and then
sudo modprobe ndiswrapper
reboot and if everything is correct we have the Our WiFi device recognized and fully functional

If you have problems please indicate it in commenting on this article.

Linux: 10 reasons to use it and prefer it

Not all users, especially Windows, have never had the luck and strength needed to try a better alternative ,In many respects, the Microsoft operating system. Excluding Mac OS X, which is always unix-based, I think everyone should try at least once in their life and if a Linux distribution, yet something stops you, here are 10 reasons why Linux is worth trying.

Compatibility with older systems

Linux runs well, very well, even on older systems, without compromising features, and is not memory hungry as Windows Vista or Windows 7. If you have an old computer hidden in the cellar, which may yet run to brush off any satisfaction if you are able to choose the right distribution.


Linux has all the 3D effects and other super pleasant aesthetic features. Some of these effects are superior to Aero in Windows 7 (as the cube, the transitions of the windows, minimizing/maximizing etc).


It is usually difficult to find a Linux distribution that makes whims in terms of stability and/or feedback system crash. Also, very importantly, Linux is faster and more fluid!


Linux is built with solid security and is very rare to encounter a virus or rootkit that could compromise the entire system. As you might guess, there is no need to install any anti-virus even if you never make the mistake of thinking that Linux, like any other environment, is an unspoiled and without threats. They exist, but are much rarer.

User Friendly

Thanks also to the wide choice of desktop environment, Linux is a very user friendly and easy to understand. It 'also possible to easily install other desktop environment if any of these are not satisfied in full. The variety and freedom, two feelings that you will experience if you use Linux.

Most devices are compatible with Linux and have, often, some modules already integrated in the kernel that allow the automatic recognition and configuration. Of course this is also a speech a little 'finer as it also depends greatly on the type of distribution you are using.

Automatic Updates
Linux provides automatic updates through the software sources, for all installed packages with their package managers are characteristic of each distribution. In addition, you can upgrade to a new version of the operating system as it becomes available.

Linux provides users with a bunch of software through the software or dedicated channels online sources. There are more than hundreds of thousands of software programs and various kinds of games, multimedia, science, graphics, education, et cetera.

Run Windows programs

In case you want to use Windows or other programs, you can 'use programs like VirtualBox or Wine. Wine is a software with which we are able to run popular Windows programs on Linux, while VirtualBox is able to emulate a version of any operating system.


Almost all things that are free for Linux. Of course you can buy games and/or professional programs, but for everyday use of Linux and more than adequate, there is no need to spend a single euro! Another great thing, you can download and install Linux as many times as you want without having to pay license or your wallet.

And you, you have any reason not to try Linux?

In fact, the new settings manager we can not manage themes, fonts, icons and many other features, even if we can get them back, thanks in part to Gnome Tweak Tool.
Among the many missing features that have come with the move to Gnome 3 are no longer the good old Account Manager which allowed us in addition to a better management of users also some useful features such as group management.

However, we can reuse the old interface of the present Gnome 2 just reinstall GNOME System Tools.

To install GNOME System Tools on Ubuntu 11.10 Oneiric just a terminal type:

sudo apt-get install gnome-system-tools

Gloobus Preview, a preview to ALL that you (updated to Oneiric Ocelot)

At last we have an option to install Gloobus Preview in Oneiric Ocelot. Requires some additional steps, but worth it. Come to see

Linux ever more surprised me. Each new application adds new features coming out of our system, and not excessively consume memory. Programs like Synapse, Radio Tray, Wine or PlayOnLinux surprised me with its capabilities and how freely and helps free users.

And this time I want to show another one of those applications. Caught my attention, mainly because without consuming a lot of RAM adds useful functionality to Nautilus: ALL preview what you have music, videos, documents, archives, folders, imagens ... The list is long.

What is your name? Gloobus Preview.

Before you know it, some details:

Nautilus needs to work
I've only tested on Ubuntu. I have no experience with other distros and this program

To install it, open a terminal and follow these steps:
sudo add-apt-repository ppa:gloobus-dev/gloobus-preview
sudo apt-get update && sudo apt-get install gloobus-preview
sudo apt-get upgrade
Installation in Oneiric Ocelot

Installation is basically the same, but here it adds a difference. As used Gnome Sushi as the default in Oneiric we have to reconfigure the space bar so that when you press open Gloobus Preview. This is accomplished by opening the terminal and typing:
sudo add-apt-repository ppa:gloobus-dev/gloobus-preview
sudo apt-get update
sudo apt-get install gloobus-preview gloobus-sushi libgdk-pixbuf2.0-dev
Then, restart Nautilus (you can log off, reboot or kill the Nautilus process in the system). You select a file, press the Space key, and start the Show:

In doing so, it will display the folder's name, weight, and content. You say: "pfff ... If you do this by reviewing the properties of the folder." Well, that's true ... Only in this example.

Let's go to another situation:

In this case we have a PDF document. And yes, it displays at the same rate as in Example No.1. Until you can afford to read it directly from there without having to open it. Quite practical, and like so you open an image:

So far it may still not be surprised ... But that's not all. This program can display the contents of your compressed files:

As you will, preview anything ... The list goes on, but I think it is necessary to continue showing more screenshots, because I proved my point. Just tell them that you can watch videos, listen music, read documents and view presentations Gloobus. And all with the space key.

This program caught my attention. I quite liked ... and will continue to improve. Already come new options. But they were not going ahead. Only I will recommend to install it and try it for yourself. I like it.

Restore the boot of Ubuntu after installing Windows

We have received in recent days an interesting email from a reader who has installed Windows 7 on a PC where there was already Ubuntu. When the installation of Windows 7 is no longer accessible Ubuntu since the boot of Microsoft Windows does not recognize the Linux Distribution.
In fact we only use at startup Windows, But fortunately we can solve this problem very easily with reinstalling the Grub Boot Loader by Default on Ubuntu through the Ubuntu livecd.

After reinstall the Ubuntu startup Bootloader we can start Ubuntu or Windows, simply by selecting the Operating System that we use. Here's how ...

For reinstall Grub need to start Ubuntu (Or other distribution) from LiveCD Once we started to know the partition where Ubuntu installed to do this just start the terminal and type:
sudo fdisk -l
the result we choose the Linux partition where you installed Ubuntu for example sda3

at this point mount the partition with Ubuntu ,to do more terminal type:
sudo mount /dev/sd** /mnt
where instead of sd** insert the partition where you installed Ubuntu detected previously in our
become as sudo mount /dev/sda3 /mnt

at this point re-install Grub to do this type:
sudo grub-install --root-directory=/mnt /dev/sda
Be careful if we want to install Grub on another hard drive just change sda with the other hard drive or partition where we want to install Grub

At this point we can restart and now we will have our Grub of Ubuntu unless we find Windows just boot from Ubuntu type:
sudo update-grub
and reboot.
