No wireless connection - SLW 14

I have a dual boot machine in which wireless works in windows but not in linux. I'm quite new to Linux so maybe there is something obvious that I have to do. Here follows some result from various commands:

lspci -v
06:01.0 Network controller: Broadcom Corporation BCM4321 802.11b/g/n (rev 01)
Subsystem: Netgear WN311B RangeMax Next 270 Mbps Wireless PCI Adapter
Flags: bus master, fast devsel, latency 32, IRQ 19
Memory at f4100000 (32-bit, non-prefetchable) [size=16K]
Kernel driver in use: b43-pci-bridge

wlan0 IEEE 802.11bg ESSID:"anniela2"
Mode:Managed Access Point: Not-Associated Tx-Power=off
Retry long limit:7 RTS thrff Fragment thrff
Encryption keyff
Power Managementn

iwlist wlan0 scanning
wlan0 Interface doesn't support scanning : Network is down

When trying to use wpa_gui to add a network using wpa2-psk and adding a password
I get the following:

Failed to enable network in wpa_supplicant

wpa_supplicant.conf :

Maybe more should be added in this file?

wpa_supplicant -B -c/etc/wpa_supplicant.conf -iwlan0
rfkill: WLAN soft blocked
Could not set interface wlan0 flags: Operation not possible due to RF-kill

wpa_cli status

I have a similar thread going in the same Forum. A guy going by Business_Kid is helping me. He says he has Broadcomm 4312 like you and me and it's working for him on slackware 14_64. If you don't have any luck here, you might want to check it out. The thread is Networks Seen but Won't Connect.

BTW I was using Slackware 13.37_64 and my networks worked pretty easily. From what I'm reading on the net, Slackware 14_64 is difficult to connect to. Most people aren't having much luck. Not sure why, BK states all the scripts are the same 13.37 to 14, but what I did to get 13.37 working isn't working for 14. Not sure why.

I'll keep you posted.

Not sure you are monitoring this thread or not, but I am now connected using Slackware 14.0_64 using broadcom 4312. See the previously listed thread and leave a message if it seems confusing.

Hi Ace,

I'm sorry to say but I gave up some days ago and installed Kubuntu which worked right out of the box. Yes I know, you learn more if you use Slackware but this was to much for me being a 68 years old electronics HW engineer! Long ago, starting at 1994, I started to use Slackware and even compiled kernels myself but now it's to complicated for me. Thanks anyhow!
