Hmm... Can't check hwinfo right now because I've installed another system in the attempt to get back online... Still not working though. Which leads me to think that I have a larger problem.

I never had to deactive my card in BIOS, haven't touched BIOS for a while, but I did switch the key on my laptop on and off a couple of times. I've done that with every attempt and verified that from the hardware side everything was on. Sadly, it was, but the light still didn't come on.

I think the WLAN card might be fried. I can't imagine how it could have happened, but after having done standard procedure to get everything going I have a hard time believing that it's SUSE's fault, especially since I managed to get SUSE online and running on a similar computer with no problems and it'd worked flawlessly in 11.3.

I think that because I've now tried installing Kubuntu und Ubuntu on it, and also tried running various live systems on it. They recognize the card, recognize the required drivers - Ubuntu & co. even asked me if I wanted to install them automatically - but even when they're installed they don't work. I've had Ubuntu 10.10 running on it as a live system before and it was able to get into the Internet, so the problem really seems to be hardware based.

So now I'm going to order a new network card and try swapping it out, seeing if that helps.

As a quick side question, does anyone have any suggestions as to what card I should order? I was thinking maybe a Netgear one, they seem to be pretty nice.

I'll let you all know as soon as I've tested whether it was just the hardware or not

Any solution so far? My Broadcom chip still sleeping........
My chip is Broadcom 4312,
09:00.0 0280: 14e4:4315 (rev 01)
0a:00.0 0200: 10ec:8136 (rev 02)
I tried every solution I found,but none of them work,is it kernel problem or Broadcom driver?

**caf4926** · 14-Mar-2011, 00:14

Code:

14e4:4315 
    partially in 2.6.33 and later 
   BCM4312 
   b/g 
   LP (r1) 
   wl

From: b43 - Linux Wireless

Looks like wl should work.

Do you also have windows? Is it working there?

Hello!

I have a similar problem with openSuse 11.4 on my Dell Vostro 1014 (Broadcom 4312, 14e4:4315).
I performed BuddelBob's instruction. My WiFi still doesn't work.

In Ubuntu 10.04 broadcom-sta works perfect.

I am not in change in this part of the forums. But maybe it would make sense to add the numeric ID

Code:

14e4:4315

also as a tag to this thread (in the section below)?
Compare the other openSUSE Forums threads tagged with 14e4:4315 .

Hi fren,I tried install wl driver with kernel that match my os,but ain't work at all. That wl driver works fine in my 11.3.
Wonder why it doesn't work with latest kernel..........
I don't have that craps called 'windows' in my clean Linux box.

**marcoslai** · 14-Mar-2011, 03:49

I just install the broadcom wi driver,again.
Current desktop kernel is 2.6.37.1-1.2-desktop x86_64
Broadcom brought in 2.6.37.1-1.2-7.pm.8.1
Does it make any difference?
Broadcom wl driver version is 5.100.82.38-7.pm.8.1-x86_64
Still not working................

**caf4926** · 14-Mar-2011, 04:26

You should have the following

broadcom-wl-5.100.82.38-7.pm.8.1.x86_64
broadcom-wl-kmp-desktop-5.100.82.38_k2.6.37.1_1.2-7.pm.8.1.x86_64

Yup these is what I installed now.
broadcom-wl-5.100.82.38-7.pm.8.1.x86_64
broadcom-wl-kmp-desktop-5.100.82.38_k2.6.37.1_1.2-7.pm.8.1.x86_64

This is weird,just now I dig into Yast > Network setting,my wifi light suddenly turn on,when I leave Network setting,it turn off.
Then I change to ifup instead of KDE Network Management plasmoid,my wifi works! It does show the spot around me,but when I change back to KDE Network Management plasmoid,wifi light off again...........
What exactly the problem is?..........

**caf4926** · 14-Mar-2011, 06:00

Are you saying you are using the palsmoid-networkmanagement?
Rather than knetworkmanager (the default from install)?

It would have been something I would have to try the
(palsmoid-networkmanagement)
