But still no wireless Internet connection.
Has anyone gotten this wireless circuit to work?
Should I try ndiswrapper?

Thanks in advance,

I have a similar card and it works perfectly with ndiswrapper - I'd give it a try.

Hello dckrinke

The key to your question is here:

Quote:

02:00.0 Network controller: Broadcom Corporation BCM4310 USB Controller (rev 01)

and in particular where it says 'USB'

The driver included in Fedora for Broadcom cards is the new b43 which uses b43-fwcutter and the b43 home site here:

http://linuxwireless.org/en/users/Dr...devicefirmware

states that USB support will never be included.

That leaves you only with the choice of ndiswrapper I'm afraid.

If you want any help with that post back.

If you go for ndiswrapper be sure to get it from one of the Fedora third party repositories so that it gets updated as the Fedora kernel changes. A not unusual occurrence.

Edit: If you do post back by the way, please include which version of Fedora you are using, it can make a difference.

dckrinke · #4 26th June 2008, 02:46 AM

How do you install ndwrapper under F9?
I don't see it in Add/Remove software.

***Firewing1*** · #5 26th June 2008, 03:02 AM

First install Livna:

Code:

su -
rpm -Uhv http://rpm.livna.org/livna-release-9.rpm

Next, ndiswrapper:

Code:

yum install ndiswrapper

Finally, download the drivers for Windows and extract them. You'll need the .inf file for your chipset to use with ndiswrapper. Once you have it, run:

Code:

ndiswrapper -i that_file.inf

dckrinke · #6 27th June 2008, 05:17 AM

Thanks for the suggestions, but what do I do now? I did:
su -
rpm -Uhv http://rpm.livna.org/livna-release-9.rpm
yum install ndiswrapper
ndiswrapper -i bcmwl6.sys

And they did seem to work.

bbfuller · #7 27th June 2008, 09:37 AM

Hello dckrinke

There are several commands you have to run after "ndiswrapper -i".

The notes below contain the whole set and you have already done some of it, but note that with differences between Fedora 8 and 9 some parts do not need to be done in the latter.

Quote:

This is the generic instruction set for installing your windows driver with ndiswrapper:

Acquire full root rights with:

Code:

su -

That's a space and a minus sign after the su. It gives full root rights over the machine, not just over your own environment which is what you get with plain su.

If you haven't already, install the Livna repository:

Code:

rpm -i http://rpm.livna.org/livna-release-9.rpm

Obviously, if you are still running Fedora 8 replace the 9 in the above with an 8

Install ndiswrapper:

Code:

yum install kmod-ndiswrapper

should bring in the three relevant packages.

The set up and configure ndiswrapper with:

Code:

ndiswrapper -i <path to your windows driver file>.inf

should install the driver,

Code:

ndiswrapper -l

if it is going to work should return "driver present" and "hardware present"

Code:

modprobe ndiswrapper

should load the driver into the kernel, but probably only until you reboot.

If you are lucky now and NetworkManager is running then after a short while it 'may' begin reporting wireless networks. NetworkManager is the preferred method of connecting to wireless networks with Fedora and should be located on the top Gnome Panel to the right in the notification area.

If it's not there, "Gnome System Menu - Administration - Services" will give you the opportunity to start it, set it to start at boot time and save the changes. {This last sentence will probably only be necesary if you have installed Fedora 8 from a DVD.}

If it works, or indeed if it doesn't you will also need to run:

Code:

ndiswrapper -ma

and then edit the file:

Quote:

/etc/modprobe.conf

as root and add the line:

Code:

alias wlan0 ndiswrapper

to it.

{Editing modprobe.conf should only be applicable to Fedora 8. In many instances Fedora 9 doesn't even have the file.}

With that all in place, reboot the computer to get the alias recognised and open "Gnome System Menu - Administration - Network", highlight your wlan0 entry, click "Edit" and make sure now that it is set NOT to "Activate device when computer starts" but that if it is there, "Controlled by NetworkManager" is ticked. That last item will only be in place if your machine is currently fairly up to date.

{This section will also probably only be applicable to Fedora 8}

Reboot and try connecting again.

If you are not able to connect at this stage, adding the line:

Code:

blacklist b43

to the file:

Code:

/etc/modprobe.d/blacklist

may help. The b43 driver is supposed to bow out gracefully but this appears not always to be the case.

If you have problems during that process I'll be looking for questions.

Hello dckrinke

You shouldn't be using "System/Administration/Network" to try and control this card.

Since the advent of Fedora 8 there have been two methods of controlling wireless cards, that and NetworkManager. NetworkManager is the default and will prevent "System/Administration/Network" from controlling the card.

"System/Administration/Network" in any case won't easily cope with any wireless encryption higher that WEP if you insist on disabling NetworkManager so it's best to go with that.

NetworkManager lives on the top Gnome Panel near the clock and on F9 starts automatically.

If your wireless is good to go, left clicking on the icon should bring a list of wireless access points to connect to and left clicking on one of those should prompt for authentication details.

That assumes that you haven't made any changes in System/Administration/Network.

If you have a card on the devices tab of that dialogue use the "Edit" button to ensure it is NOT set to "activate device when computer starts", but that it is set to be "controlled by networkmanager"

If the card doesn't activate then we may need to run some diagnostics.

dckrinke · #10 28th June 2008, 11:53 PM

bbfuller · #11 28th June 2008, 11:59 PM

Hello dckrinke

Try:

Code:

su -

Code:

iwconfig

Code:

iwlist wlan0 scan

and

Code:

dmesg | grep ndiswrapper

Code:

dmesg | grep wlan0

all or any of which may give us clues as to what is happening.

By the way, I assume you used the Windows XP driver package for your card. Ndiswrapper won't work with the Vista drivers.

Hello dckrinke

This line from the output of dmesg tells us where the failure lies.

Quote:

ndiswrapper (load_wrap_driver:112): couldn't load driver bcmwl6; check system log for messages from 'loadndisdriver'

I think that's an ndiswrapper failure rather than a Fedora failure.

I assume that you are using the XP driver as I suggested?

I've had a quick look on the internet and I've found a case where the user of a card with the identity of yours (14E4:4315) got the card working with ndiswrapper but they used a bcmwl5 driver. Ndiswrapper is not equally happy with all of the windows drivers.

The link to the driver they used is here:

http://ftp.us.dell.com/network/Dell_...17_R174291.exe

and I'd be tempted to give it a try.

The page I found that on is here:

http://ndiswrapper.sourceforge.net/j...do,export_raw/

You can remove an existing ndiswrapper driver with:

Code:

ndiswrapper -e bcmwl6

as an example.

Dells drivers can usually be unpacked with:

Code:

unzip -a <dell driver name> -d /driver

Hope that helps.

Hello sleetm

It's got to be to do with permissions or paths.

I presume you are logged in as an ordinary user and have used a variant of the su command to obtain your root privileges?

Did you use:

Code:

su -

the space and the minus sign are important, without them you only get root privileges over your ordiary users area, with them you get control over the whole machine.

Alternatively, try issuing the modprobe command from somewhere other than in your Download directory.
