intel3945 WLAN and Siemens ADSL Modem

[d das]

Thanks dear Young and Ellertson for your help. And also to Peter
Skensved who replied to this mail personally. Yes, the Hardware switch
was off. I was quite stupid to not interpret the 'HW RF kill switch
part'. After making the switch on in front of the machine, the
wireless thing is active. But now 'ifup wlan0' is giving this message:

<<
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0; Invalid argument.

Determining IP information for wlan0... failed.
>>

Can anyone please suggest what I have got to do? The ehernet LAN is
working properly between the laptop and the modem. And now I have kept
the ethernet cable unplugged.
