Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Run the following command (copy-paste the line below into a Terminal, press enter, then enter password when sudo asks for password, then press enter again)

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; uname -a; dmesg | grep ound; dmesg | grep b43; iwconfig

Step 3: Please post results (copy/paste terminal output) on this thread

==============================================================================================================

Keep in mind that one or more of the following 5 basic components need to be configured correctly so that wireless can work correctly in Linux:

Wireless configuration in the BIOS, hardware wireless switch setting, active wireless driver version, the firmware for the wireless chipset (stored as a file in Linux), and the configuration of the wireless parameters in wicd or NetworkManager (SSID broadcast settings, encryption settings, name of wireless interface stored in wicd, the chosen channel for wireless transmission, ...) .

In case your wireless interface is DISABLED, please make sure the /etc/network/interfaces file only contains the following 4 lines (you can edit the file using the command gksudo gedit /etc/network/interfaces) :

auto lo
iface lo inet loopback
auto <name of wireless interface>
iface <name of wireless interface> inet dhcp

where you need to replace <name of wireless interface> with a real value inside this file: wlan0 or ath0 or eth1 or something like that. You can find the right value by running the command iwconfig

Here is an example of a real, working /etc/network/interfaces file:

auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet dhcp

Regards,

Mark

Hi,

Please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (copy-paste each line into the Terminal, press <enter> after each line)

sudo aptitude update

sudo aptitude install build-essential subversion

cd ~

wget http://snapshots.madwifi-project.org/madwifi-trunk-current.tar.gz

tar xvf madwifi-trunk-current.tar.gz

cd madwifi-trunk-r4031-20090529

make

sudo make install

gksudo gedit /etc/modules

# Now add the Atheros kernel module ath_pci to the list of modules to be automatically loaded at boot by adding

ath_pci

# to the end of the /etc/modules file. (Gedit editor automatically opens)

gksudo gedit /etc/modprobe.d/blacklist.conf

# Now add the following 3 lines at the end of the /etc/modprobe.d/blacklist.conf file:

blacklist ath5k_pci
blacklist ATL1E
blacklist ath5k

# Now you can reboot and it should work.

Hope this helps,

Regards,

Mark

Hi,

One more thing: in Ubuntu 8.04, the blacklist file is called /etc/modprobe.d/blacklist

In Ubuntu 9.04, the blacklist file is called /etc/modprobe.d/blacklist.conf

I have taken the advice and have made progress for the first time after days of work

I initially didn't see the enable wireless icon I set up the interfaces file and ran the madwifi file as suggested and although wifi is now enabled the wifi light doesn't light up and the wifi interface which has now come up says it's unknown

I enclose the code results of the advised command before and after my work

The wifi light still won't light up and I can't use wifi

I wonder if you can give me further assistance

I have taken the advice and have made progress for the first time after days of work

I initially didn't see the enable wireless icon I set up the interfaces file and ran the madwifi file as suggested and although wifi is now enabled the wifi light doesn't light up and the wifi interface which has now come up says it's unknown

I enclose the code results of the advised command before and after my work
