Question Wireless Not Working


Hi Guys!

I'm running OpenSuse 11.0 on a Dell Inspiron 1520 but my wireless is not working properly. The system recognizes the wireless card but when I try to search for wireless networks around me nothing comes up. (I do have my wireless router working) can you guys help me?
thanks

I run /sbin/lspci -v and these are the results for my wlan0 :

0c:00.0 Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01)
Subsystem: Dell Device 0007
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at fe8fc000 (32-bit, non-prefetchable) [size=16K]

Capabilities: [58] Message Signalled Interrupts: Mask- 64bit- Queue=0/0 Enable-
Capabilities: [d0] Express Legacy Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting <?>
Capabilities: [13c] Virtual Channel <?>
Kernel driver in use: b43-pci-bridge


Thanks for your help!!!

Ahh I thought the Dell laptops were pretty much all Fn+F2 to enable/disable Wireless.. Are you SURE it's enabled via the button ?

Just looked at one of these the other day, and 'Signal Level 0' indicated wireless as being disabled in BIOS or via switch, etc..

From the FAQ http://linuxwireless.org/en/users/Drivers/b43/faq
Quote:
Q: The LEDs do not work.
A: You have to enable LEDs support in the kernel configuration. The config options you have to enable are: CONFIG_LEDS_CLASS, CONFIG_LEDS_TRIGGERS, CONFIG_MAC80211_LEDS.

Q: The radio-enable-button on my laptop does not work.
A: You have to enable RF-kill support in the kernel configuration. The config options you have to enable are: CONFIG_RFKILL, CONFIG_RFKILL_INPUT, CONFIG_INPUT_POLLDEV.

Q: After enabling the config options, LEDs/RF-kill still don't work.
A: If you have the b43/b43legacy driver built-in (not as a module), you must also enable all the LEDs/RF-kill options (see above) built-in (not as a module).

Q: It all loaded but my signal strength is 0
A: If iwconfig shows
* Link Quality:0 Signal level:0
then you may have wireless disabled in the BIOS. Check for things like "Wireless : Application Control".
Not sure what else to tell you..

for the 4311 tyou should be running the new STA driver
http://www.broadcom.com/support/802.11/linux_sta.php

I don't know what drivers you have currently loaded.. maybe the issue is you have an older version of the driver installed..http://www.broadcom.com/docs/linux_sta/README.txt

What is output of iwlist wlan0 scan? If you have a access point you want to connect to, you can enter it via iwconfig (man iwconfig).

But as noted, the 0 signal level may indicate your NIC is disabled.

ok guys! I got my wireless working! :=) this is what I did:
/var/log # tail -f messages wlan was missing firmware
I went to http://linuxwireless.org/en/users/Drivers/b43 where I found the following command:
sudo /usr/sbin/install_bcm43xx_firmware and I run it on my system. I restarted and now my wireless is working! It took some research and work but I'm glad it worked! Thanks guys!

Does this work on other wireless chips?
Mine is an Atheros AR242x, and the light is always red (which means disabled) even when is enabled and connected (which should be blue).
