Hello everyone !

I am trying to configure wirless network on Ubuntu but getting the following error when do "iwlist scan":

lo Interface doesn't support scanning.

eth0 Interface doesn't support scanning.


pan0 Interface doesn't support scanning.



Pls advise !

is this is because the wireless interface is not detected ?
Can you try the command
iwconfig
as root. This will show the wireless interfaces.
Also
please give us the output of lspci

Thanks Bhaskar !

iwconfig gives the following error:

lo no wireless extension

eth0 no wireless extension

pan0 no wireless extension


lspci gives the following:

00:00:0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host Bridge (rev 03)

00:01:0 PCI bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX AGP Bridge (rev 03)

01:00:00 VGA Compatible Controller: ATI Technologies Inc 3D Rage Pro AGP 1x/2x (rev 5c)

This just means that the wireless interface is not up ! i.e this is a driver installation issue.
From the lspci listing I can see that there is one network card which is detected as eth0 and it is
a wired interface
Now, where is the wireless device ? it does not show up. Are you sure that there is a wireless network card in your system ?

Please post the hardware you are using. If this is a USB wireless adapter include the output of the lsusb command.
