Need to turn on wireless card on Gateway 7510G AMD 64 laptop w/Kubuntu 8.10


I've installed Kubuntu 8.10 on a Gateway 7510G AMD 64 Laptop.. runs great, just can't figure out how to turn on the wireless card. Under Windows the Fn+F2 key combo turned the card off/on - a symbol would light up when the card was on. Under Linux the key combo doesn't seem to work. I've loaded the drivers (which was "fun").

I've pulled up the user manuals, etc for the laptop online and the key combo is the only means to turn card off/on..there is no physical switch (like on my newer Dell).

How can I get the card turned on? Windows is gone, it's a linux only machine now.

I'm hoping there is something in the BIOS or a way to map the keys to make the key combo work, maybe?

Help please....

If the symbol does not light up when you load the driver, it might not know about the light. Usually those things are controlled by a GPIO pin in the chipset. The light being on or off may not have anything to do with the operation of the card.

If you know what register in PCI space turns on the light, you might be use setpci. You would need the datasheet for your chipset. If it was an Intel chipset, that would be easy to get. I do not know how much documentation AMD makes available.

Good luck...

Does your wireless card work? If so, why do you need an on/off switch?

David1357,

Right now the card does not seemed to be recognized. If the light is suppose to come on when the driver is correctly loaded, then the driver didn't take.

I've tried to ping the router, nothing. That's primarily why I believe the card is not "on". The Network Manager should show a card being present..if I understand correctly... but nothing is there.

If the light does or doesn't work under Linux.. that's fine. I just want the wireless connectivity.

PTrenholme,
I don't "need" the on/off switch, but it exist. A software-only switch, in some of the how-tos I've read it advises to jump back into windows, turn the wireless card on then jump back to Linux. That scenario assumes you are dual booted. My laptop is Linux only...so that isn't an option for me. I'd find it hard to believe that there is no way to turn on the card...

It's a Broadcomm 4318 wireless card.

Get ready to suspend your disbelief. You are entering the world of wireless devices and their infinite variety.

There probably is a way, and it probably requires toggling a bit in the PCI configuration space. Finding out which bit you need to toggle will be very difficult. Apparently, you had some handler in Windows for that key combination that did the necessary bit toggling. My guess is there was a custom driver for your system that did the necessary work.

I am sorry to be the bearer of bad news.

David 1357,

That sucks but it is what it is...I'm willing to play with that. Where do I start? What is the name of the spec or layout I am trying to find?

This is the first time I've played with laptops and Linux.

Worse case, could I not just buy another "Linux friendly" wireless card and install that?

Or would this PCI bit toggle issue still be in the way?

Once this issue is conquered, will it be possible to map a key combo to toggle the wireless card as under windows?

At the very least I want the card to stay permanently on. I don't want to have to mess with it everytime it boots up, you know?

Thanks

If you buy a card that goes in your PCMCIA/CardBus/PCIE slot, that would work.

The line that turns on that light may also be connected to the line that powers the actual card. If you buy another internal card, you may have the same problem.

Almost anything that is possible on Windows is possible on Linux. But it may take a lot of work.

Yes, I completely understand that. On the other hand, laptop hardware is difficult to modify.

Did you run the b43_fwcutter program to install the required Broadcom firmware? If not, the card won't work with the b43 driver that's installed by default.

PTrenholme,

I did run the b43-fwcutter utility, I believe I did it correctly. Is there a way to tell if the driver is loaded correctly when the wireless card concerned is not responding?

This is what I get with iwconfig:

I have that device in my home laptop. It works great with the b43 driver in Ubuntu 8.10.

Verify that the driver is loaded by running "lsmod" and looking for "b43".

Running lsmod provides the following output: I bolded the things that had b43 associated with them. Module b43 has a "Used by" of 0 -- I assume this means there is no driver, correct?

No. It just means no other drivers are using b43, which is what you would expect.

So we know the driver loaded. Now it is time to look at the output of "dmesg" and see if the driver had any problems while loading.

David1357,

What version of firmware are you using for your BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)? 4.150.10.5, b43legacy or bcm43xx? I downloaded the bcm43xx... would the newest be better?

No, the problem you have is that you've installed ndiswrapper. You cannot use two different drivers for the same device (unless they share memory, which the b43 and ndiswrapper driver do not).

Remove the old, obsolete, and unneeded ndiswrapper driver and reboot. Or just do a modprobe -r ndiswrapper to see if removing it fixes your problem and then remove it if it does.

Since you're using Ubuntu, you (presumably) did an apt-get install ndiswrapper to install it, so an apt-get remove ndiswrapper should remove it. If you installed it by some other method, let us know what you did so we can help you get rid of the interfering software.
