Computer Learning, My Free Writing on Computer and Information technology

I have installing it perfectly and everything is just works…But suddenly when i see my WiFi, it’s not working….. After some browsing, i found out that HP Pressario C767 is using Antheros just like Acer 4520. So i have to use ndiswrapper to diswrap the antheros driver for windows so the wifi will be recognized in Ubuntu.

To download the Antheros driver for Linux, click the download section from here. After you have downloaded it, extract to a place on your hard disk. Then use ndisgtk:

Click System > administration > windows wireless driver, browse for the .inf driver for atheros

After that, you may configure the Wifi by clicking system > administration > network settings.

These are the specifications of Acer 4520

• AMD Turion 64?2 TL-58
• VGA NVIDIA GeForce 7000M
• HDD 80GB
• WLAN atheros AR5006EG 802.11 b/g
• Acer Crystal Eye webcam

When ubuntu first installed, the VGA can only support the safe graphic mode and the sound card cannot performs. Luckily there are methods to fix this thing.

1. Insert Ubuntu’s CD (all version, you may use Xubuntu, ubuntu, edubuntu, etc)
2. choose Save graphic mode
3. Install as usual
4. configure APT so to enable repository DVD’s based instasllation , but if you have internet connection, then you don’t have to configure it
5. Install these packages
   1. nvidia-glx-new (VGA)
   2. linux-restricted-modules (sound card)
   3. linux-backports-modules (sound card)
   4. ndiswrapper-common (Atheros wifi)
   5. ndisgtk (Atheros wifi visual)
   6. ndiswrapper-utils-1.9 (dependency
      ndisgtk)
   7. cheese (webcam)
6. Download the driver net5211.inf (the Win XP version not the Vista version) , you can search via Google, the file usually archieved
7. extract the archieved driver
8. Execute this programs

    # ndiswrapper -i net5211.inf
   
   # ndiswrapper -l //make sure the device status is present
   
   # ndiswrapper -m //make sure the latest line shows wlan0 alias
   
   # ndiswrapper -ma
   
   # loadndisdriver

9. Configure sound

   //sound configuration
   
   nano /etc/modprobe.d/alsa-based //add text below on the last line.
   
   options snd-hda-intel model=acer

10. Save/CTRL + X
11. Click System > Administrator > Restricted Driver Manager
12. Enable VGA Driver
13. Restart your PC

PS: There are some laptops that use broadcomm WIFI instead of antheros, so install the driver:

#apt-get install bcm43xx-fwcutter

restart without installing ndiswrapper.
