Wireless Not working

hi
i am gobi.. i installed pardus linux 2008 beta version. I heard it is similar to ubuntu.so i upgraded pardus linux from ubuntu. Audio and graphics are working fine in it. But my wireless device is not working.i tried some commands, and the output of those commands are
--------------------
~ # iwconfig

eth0 no wireless extensions.

Many wireless devices will not show up in Linux until you install/compile drivers/modules for them.
Also, many are already supported by Linux and the driver is included with the kernel, but you need to install the proprietary part which is the firmware.

If you can provide the name and type of wireless device, or the name and model number of your computer so the type of wireless device can be tracked down, then someone can steer you in the right direction. Without that information, it's highly unlikely you'll get the advice you need.

The command: lspci or sudo lspci may also provide that information.

Hi,

Please post 'ifconfig -a' along with the suggested commands. Please post unedited within the vbcode tags (quote or code) at the top of the reply window.

Hi,

You should place the data within the code tags as suggested! It makes things a lot neater and easier to read.

Your wlan0 is recognized. You need to get a IP and a proper kernel route table.

I would setup a static IP first, do as root from cli;

Code:

~#ifconfig -a                      #get recognized devices
~#ifconfig wlan0 192.168.0.10       #set to a available IP
~#route add default gw 192.168.0.1 #set to your gateway
~#route -n                         #show the route table
~#ifconfig wlan0 up                 #should be up already
~#ping 192.168.0.1                 #ping your gateway
~#ping 208.69.32.130               #google.com IP
~#ping google.com                  #test DNS, if fail then
                                   #check /etc/resolv.conf

You should have your '/etc/resolv.conf' setup with your 'ISP DNS' nameservers.

If the above static works then you should setup your configuration files.

Hi
Thanks for your reply. I tried the above commands ,but still its not working.

Hi,

Don't use the IP address in the example unless they match your subnet. It looks like you are using '192.168.2.x' so your wlan0 IP could be '192.168.2.10' with your gateway as '192.168.2.1'. The information in your kernel route table shows that the 'eth0' device is the default device.

Which device do you want to use?

If you follow the example that I gave you to setup a static IP as the device be sure you use the subnet '192.168.2.x' if that is your subnet.
