I brought a new DELL Inspiron 5220. It's amazing!
- 3rd Generation i5 Processor
- 4GB RAM
- 1TB Hard Disk
- 15" Screen
- 1GB Graphics
It ships with Windows 8! ;)
However, made a dual boot upon it. Although BIOS looked different this time!!
I'm working on Ubuntu :)
Release : 11.10 (Oneiric)
Kernel Linux : 3.0.0-28-generic
But Wi-Fi was not getting detected. This was not unusual, as I had set this up in earlier Dell models.
Well, the remedy is easy.
Step 1: Make sure that you can witness the Device Card and the ID. Especially, the Network !!
Type in the following command.
$ lspci -nnk | grep Network
08:00.0 Network controller : Intel Corporation Device [8086:0887] (rev c4)
Step 2: Figure out which kernel version. This is because the driver which we will be installing works on 2.6.37 or higher
$ uname -a
Linux Swathi 3.0.0-28-generic #45-Ubuntu SMP Wed Nov 14 21:57:26 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Step 3: Install the network manager
$ sudo apt-get install network-manager*
Step 4: Install few packages
$ sudo apt-get install build-essential linux-headersStep 5: Check the output of
If it outputs the failure of firmware file, then its time to download the .ucode and place it in /lib/firmware.
It should be working. If not, try Step 6.
Step 6: Download the compat wireless tarball from this location
Extract from the tarball
$ tar -xvf <path_to_compat_wireless_bz2>
$ cd <extracted_path_compat_wireless>
Installing the packages
$ sudo make install
After this command it will show on the console the command to disable bluetooth, ethernet and Wi-Fi. Type in the 3 commands.
Place this module into the kernel.
$ sudo modprobe alxThe Ethernet LAN should be detected.
Add the driver module into this file : /etc/modules
Append the following lines. Don't touch the rest. This will enable this module while restarting the system as it loads the module.
$ sudo vi /etc/modules
Reboot your machine.
You must witness "Wi-Fi Networks Available!" notification on you desktop :)
Happy Learning! :)
