[SOLVED] Wireless stopped working - HP nc8430

When I rebooted my laptop today, I can't connect to the wireless anymore.

# ping 192.168.1.1
connect: Network is unreachable

stepping through my connect script:

# cat /usr/local/bin/wireless-startup
ip link set wlan0 up
wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf
dhcpd wlan0 > /dev/null

# ip link set wlan0 up
RTNETLINK answers: Operation not possible due to RF-kill

This looks suspicious to me.... however I have no clue what RTNETLINK or RF-kill is.

I should also note that the wireless button with a LED, which looks like this: (( i )) is off, and pressing the button does not turn it on.

What has happend? Is it a HW setting, or a kernel problem, or a misconfiguration? The wireless connection worked perfectly before today. Thanks for any help.

RF kill is a tool you should have installed if you've wireless.  It lets you see if there is a hardware or logical switch that prevents your wireless from transmitting.

ewaller$@$odin ~ [1]1002 %rfkill list
0: hp-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
ewaller$@$odin ~ 1003 %pacman -Qo $(which rfkill)
/usr/sbin/rfkill is owned by rfkill 0.4-7
ewaller$@$odin ~ 1004 %

Also, as a sanity check, please post the output of ip link

Thanks.

Yes! I'm back! I had to plug in a wired network and reboot the machine with the wired network just to sync RF-kill, since it was not installed.
After installing rfkill, I did some simple tests, and then I just added the service:

# systemctl enable rfkill-unblock@all

Reboot.... and it works like a charm again!

Thanks ewaller!
