Hi gurus,
I am trying make wireless card working but I am stuck. Tried following:

Hardware button for wifi is enabled (wifi led lights):

Code:
[root@HP-PC ~]# modprobe -r iwl3945
[root@HP-PC ~]# modprobe iwl3945

[root@HP-PC ~]# ifconfig wlan0 up
SIOCSIFFLAGS: No such device

[root@HP-PC ~]# ifup wlan0
/sbin/ifup: configuration for wlan0 not found.
Usage: ifup <device name>

[root@HP-PC network-scripts]# dmesg | tail -n 30

Hardware button for wifi is disabled (wifi led is grey):

Also in both cases tried:

Code:
[root@HP-PC ~]#  rfkill unblock all

This seems weird because AFAIK "Radio disabled by HW RF Kill switch" means that wifi is disabled by hardware swtich. But this message appers in dmsg when hardware switch was on.

CONFIGURATION:

WLAN Card:

Code:
[root@HP-PC network-scripts]# iwconfig

GGoogling around, it seems there are several ways to flip options so the soft switch is not a problem. "Radio disabled by HW RF Kill switch" - Google Search
