RTNETLINK answers: Operation not possible due to RF-kill

I've installed Slackware-current on a Dell Latitude E5420 laptop with Intel i3-2350M and 4G of memory. I'm trying to get the WiFi working. I have the following in /etc/rc.d/rc.inet1.conf
Code:IFNAME[4]="wlan0"
IPADDR[4]=""
NETMASK[4]=""
USE_DHCP[4]="yes"The WiFi toggle switch on the laptop is enabled. I have the correct configuration in /etc/wpa_supplicant.conf (I've used this same config elsewhere).

When I try to start the WiFi I get:
Code:# /etc/rc.d/rc.inet1 wlan0_restart

0a:00.0 Ethernet controller: Broadcom Inc. and subsidiaries NetXtreme BCM5761 Gigabit Ethernet PCIe (rev 10)I did have Slackware 14.2 on this computer before installing current, but I really don't know if I've ever tried using the WiFi before.

Any suggestions on what I can do or try?
