A.R. Rahman bags 2 oscars
A.R. Rahman bags 2 oscars and sets India on the global movie map. He has won the oscars for the best score and song for the movie "the Slumdog Millionaire". Though this should have been awarded a long time ago, I think this is one that Rahman truely deserved.

Getting wireless to work in Ubuntu/Kubuntu 8.04 with atheros wireless card 5007EG - III
Getting WIFI Led to work:-
In this post, I'll describe on how to get the WIFI LED, if any on acer laptops to work. The ndiswrapper driver I used would normally not give a working LED or might be it would work with very low intensity.
The following method involves editing a file associated with the ndiswrapper driver installation and cannot be used for the madwifi installation. If I find any useful information on how to get the LED working in madwifi, I'll try posting that too.
First type the following command from command line and check for the output:-
Then open the above file as root from terminal by using the following command in case of ubuntu:
After the "DriverDesc|NDIS Network Adapter" line add the following 2 lines:-
In my next post, I'll discuss on getting your network to a higher level of security such as WPA-PSK/WPA2-PSK than WEP. I'll try posting about this in a week or so.

First type the following command from command line and check for the output:-
xxxx@yyyyyy-laptop:~$ ndiswrapper -lhere (168C:001C) means my device is listed under this sub-driver. Then you have to travel to /etc/ndiswrapper/net5211/ and check for the filename like 168C:001C.5.conf. Yours would be different as per the output of the "ndiswrapper -l" command.
net5211 : driver installed
device (168C:001C) present (alternate driver: ath_pci)
Then open the above file as root from terminal by using the following command in case of ubuntu:
sudo gedit /etc/ndiswrapper/net5211/168C:001C.5.confand the following command in case of kubutu:
sudo kate /etc/ndiswrapper/net5211/168C:001C.5.confThe file will look something like this:-
sys_files|ar5211.sysThe (........) only means that other lines might be present. Please don't go about adding ....... to your file.
NdisVersion|0x50001
Environment|1
class_guid|4d36e972-e325-11ce-bfc1-08002be10318
driver_version|,07/25/2007,5.0.3.67
BusType|5
SlotNumber|01
NetCfgInstanceId|{28022A01-1234-5678-ABCDE-123813291A00}
..................
..........
DriverDesc|NDIS Network Adapter
................
After the "DriverDesc|NDIS Network Adapter" line add the following 2 lines:-
If "gpioPinFunc1|3" is already present, then add the gpioLedCustom|4 line alone. In gpioLedCustom|X, the last X can be anything between 1 to 4, This only makes the LED blink at different rates when it is idle. When you connect to a network, it all changes to normal. Finally you need to unload and reload the driver to check the LED utility. This can be donw using the following commands:
gpioPinFunc1|3
gpioLedCustom|4
sudo modprobe -r ndiswrapperThereafter the LED should be working correctly.
sudo modprobe ndiswrapper
In my next post, I'll discuss on getting your network to a higher level of security such as WPA-PSK/WPA2-PSK than WEP. I'll try posting about this in a week or so.
Getting wireless to work in Ubuntu/Kubuntu 8.04 with atheros wireless card 5007EG - II
In this post, I'll describe about installing the madwifi drivers.
2)MADWIFI:-
This will surely be the future where further development will be made as it would seem. Though I dont think this is as good as ndiswrapper at present, this surely has loads of tools that made me enjoy tweaking with it. But I struggled to get it working though. You can try this, if the ndiswrapper method did not work or you don't want the word windows anywhere near you.
So continue using your network, till my next post on how to get the LED working as well as getting your network to a higher level of security namely WAP-PSK/WAP2/PSK than just WEP.
My next post will be on how to get the wireless LED working(with ndiswrapper).

First go to System–>Administration–>Hardware Drivers” and disable by un-ticking the following option- Atheros Hardware Access Layer (Hal). Then Reboot your system.
sudo apt-get install build-essential in a terminal or using synaptic as you wish. Also install all the dependencies.
open the terminal from Applications–>Accessories–>Terminal and type the followind commands in the order given below.
wget http://snapshots.madwifi.org/special/madwifi-ng-r2756+ar5007.tar.gz
tar xfz madwifi-ng-r2756+ar5007.tar.gz
cd madwifi-ng-r2756+ar5007
make
sudo make install
sudo modprobe ath_pci
sudo reboot(or restart your system manually)
if wget command doesn't work properly, you can directly download the file from the given link above to anywhere on your system. Change to that directory using your terminal and execute the remaining commands.
That should do. Now your wireless should work without any problem, just like ndiswrapper installation. If I'm correct the LED will not work, even here(especially with acer laptops). But as far as I know, there seems to be no way of getting it to work with madwifi. If you are ready to do away with the led, then you could be having the best set of madwifi tools available.
So continue using your network, till my next post on how to get the LED working as well as getting your network to a higher level of security namely WAP-PSK/WAP2/PSK than just WEP.
My next post will be on how to get the wireless LED working(with ndiswrapper).
Getting wireless to work in Ubuntu/Kubuntu 8.04 with atheros wireless card 5007EG - I
I did have some ..... well to say the truth, a lot of trouble in getting wireless to work in ubuntu. Mine being an atheros 242x 5007eg card kind of saved me from the hectic work as most of the nice people in the ubuntu development section had already put the critical code on how to get the WIFI up with ubuntu.
For a first time user, all those can be very hectic. I didn't understand what ndiswrapper was or what madwifi was. I went about reading lot of forums/posts to get an idea on how to go about them. And to say the truth, I'm happy that I did some reading because I have got nearly each and every component in my laptop to work - from the wifiadapter to its led. Explain the 2 major wifi drivers in linux in as simple terms as possible.
ndiswrapper - using a driver created by atheros/microsoft for windows operating system in linux using a wrapper around it to work properly in linux.
madwifi - Open source linux wifi drivers running on top of proprietary HAL(Hardware Abstraction layer). I got the above sentence from madwifi site. They are also working on the new drivers to madwifi namely the ath5k and ath9k. Go here madwifi.org to learn much more about the madwifi. There are some excellent madwifitools available that can be of extreme use to the users
Most of them have used both and feel that both of them are equally good, though I felt the ndiswrapper was slightly better and the faster method.
So what both the drivers do is to detect the wireless card on your system. It doesn't scan for networks automatically and connect to them and all. Just tell the OS that there is a wireless card in your system.
Here I'll try illustrating the step to get your wireless card to be detected in your system. I did use the ndiswrapper method, so I'll go about it first.
Ubuntu/kubuntu 8.04 comes with a version of madwifi installed that doesn't account for much. It didn't work for me. So I went for ndiswrapper, just because it was easy to install than madwifi. But still madwifi will be the future in linux.
1)NDISWRAPPER:-
First you have to disable the madwifi drivers from being loaded at startup as you are going to use the ndiswrapper. This can be done in 2 steps.
(enter your account password if asked to at this point)
The /etc/modprobe.d/blacklist is actually like a text file, so open and check whether the line "blacklist ath_pci" is added to it using gedit or kate.
iwlist wlan0 scan
(it can be wlanX or even ethX or athX, you can check that by using the command ifconfig or iwconfig in a terminal/console to see the correct name of your wireless interface.)
If you are not able to see any networks, then try scanning again, after pressing any wireless button(if any present) that you use for turning on your wireless. For me (aspire 4720z), this button was at the top of the laptop keyboard. You should be able to detect some network like this:-
If you get something like the above that means, you are able to detect your network properly. If your network is unencrypted or uses WEP encryption, you should be able to browse right away using Network Manager in ubuntu or KNetwork Manager in kubuntu, after giving necessary ip settings and WEP passwords etc. I did prefer WIFI-Radar, as It did detect my network automatically and I was able to browse instantly.
All this time, the wireless LED, if any on some acer laptops would not have worked or worked with very little brightness. I'll explain on how to get that working in the future posts. Next I'll give an brief overlook of madwifi installation.

1)NDISWRAPPER:-
First you have to disable the madwifi drivers from being loaded at startup as you are going to use the ndiswrapper. This can be done in 2 steps.
- First, If you are using ubuntu, goto "System–>Administration–>Hardware Drivers” and disable by un-ticking the following option. Incase of kubuntu , goto "System->Hardware Drivers Manager" and do the same.
For making sure that the system does'nt load these drivers automatically at restart, execute the following command in a terminal or console.
(enter your account password if asked to at this point)
The /etc/modprobe.d/blacklist is actually like a text file, so open and check whether the line "blacklist ath_pci" is added to it using gedit or kate.
Restart the system after the previous step.
- Incase of adept manager in kubuntu, just search for ndiswrapper and ndisgtk and install the following packages:- ndiswrapper-common, ndiswrapper-utils-1.9 and ndisgtk. Incase of synaptic in ubuntu, you might have to enable the multiverse and universe repositories. This can be done by following the steps in this page in the ubuntu wiki - here.
After installing the above softwares, you'll get the "Windows wireless Drivers" menu either in "System->Administration" or "System" menu. Click on it. A window as below will open up.
- In this window, click on "Install New Driver" and point to "net5211.inf". This file is one of the many files in a zip file that has to be downloaded from atheros directly if possible. The name of the driver file that worked for me was from acer site itself, the link was ftp://ftp.work.acer-euro.com/notebook/aspire_5110/driver/Wireless_Atheros_V5.3.0.67_XP_XB63_XB62(WHQL).zip unzip this file and traverse to "Wireless_Atheros_V5.3.0.67_XP_XB63_XB62(WHQL)/Drivers/XP-x32" folder in the zip file. There you can find the 32-bit wireless drivers i.e. net5211.inf file. If you are ot able to get this driver, the try getting an atheros driver that is atleast WHQL (that could do).select it and install the driver.
After installing, just check whether the line after the driver name in ndisgtk changes to hardware present is "YES". That means you have installed the right drivers for your wireless card. If it shows that the hardware is not present, then you might need to try some other drivers, or check for the correct wireless card in your laptop.
iwlist wlan0 scan
(it can be wlanX or even ethX or athX, you can check that by using the command ifconfig or iwconfig in a terminal/console to see the correct name of your wireless interface.)
If you are not able to see any networks, then try scanning again, after pressing any wireless button(if any present) that you use for turning on your wireless. For me (aspire 4720z), this button was at the top of the laptop keyboard. You should be able to detect some network like this:-

If you get something like the above that means, you are able to detect your network properly. If your network is unencrypted or uses WEP encryption, you should be able to browse right away using Network Manager in ubuntu or KNetwork Manager in kubuntu, after giving necessary ip settings and WEP passwords etc. I did prefer WIFI-Radar, as It did detect my network automatically and I was able to browse instantly.
All this time, the wireless LED, if any on some acer laptops would not have worked or worked with very little brightness. I'll explain on how to get that working in the future posts. Next I'll give an brief overlook of madwifi installation.
