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

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.

Might help. Might not.

wireless - How can I enable wifi on my Ubuntu 11.10 xps l702x? - Ask Ubuntu

A guy using fedora 16 used that fix also

[SOLVED] FC16: wlan hardware blocked

**wakatana** · 10-02-2012

Thank you, I will try ASAP and report

**wakatana** · 10-02-2012

unfortunatelly did not help, any other ideas ? is somehow possible to check if wireless NIC is not physically damaged ?

The wireless card seems OK. No damage seen, The hard block is a wireless key issue. My suggestion is to boot a newer fedora live cd

Fedora Project - Download Fedora and try it.

and see if hard block is still in effect running live. Your wireless key may be malfunctioning. Other than that. A wireless bios setting may need to be changed.

**wakatana** · 10-03-2012

I am not so shure about hardware damage. Also seems that problem is also on W7, neither windows nor netstrumbler software simply wont scan netowrks. Netstrumbler also report some error message regarding adapter. In windows seems that everything is installed, I tried also download official drivers from intel on windows, no luck. What do you mean by bios setting changing ? Some kind of firmware flashing ? Will try live fedora ASAP. Regards

**wakatana** · 11-06-2012

Problem solved
LAN/WLAN switching have to be turned off in the BIOS settings
