Problem with 3com wireless pccard Wi-fi

Thanks for your question, but I don't understand well your problem, you want a driver for your 3com router ??? This is the problem, right, or I mistake.

thanks

No its the wireless card the router works fine

For all we will done you must open a shell
If you have a fresh install of Ubuntu, you need to remove any and all versions of Ndiswrapper that come installed by default on your system:

$: sudo rmmod ndiswrapper

$: sudo apt-get remove ndiswrapper-utils

Don't worry if you get errors about not being able to find or remove these -- we're just making sure they're not present before we get started

We'll need to install compiling tools (don't panic when you read that, just bear with me), the latest kernel headers, and then the source code for the latest ndiswrapper (seriously, don't panic. This will be very simple).

$: sudo apt-get update

$: sudo apt-get install build-essential

$: sudo apt-get install linux-headers-`uname -r`

Now we make a dir where we download all

$: mkdir wi-fi

$: cd wi-fi

At this point, you need to go to the ndiswrapper sourceforge site and get the latest version of the Ndiswrapper program. As of 1 April 2007, the latest version is 1.41:

$: wget http://internap.dl.sourceforge.net/sourceforge/ndiswrapper/ndiswrapper-1.41.tar.gz

Uncompress the ndiswrapper source (in my example, the file name is ndiswrapper-1.41.tar.gz):

$: tar -xzvf ndiswrapper-1.41.tar.gz

We now install the module:

$: cd ndiswrapper-1.41

$: make uninstall

$: make

$: sudo make install

$: cd ..

we need to blacklist the broken and useless bcm43xx firmware drivers that try to load in a default ubuntu install:

$: sudo -s

$: echo blacklist ieee80211 >> /etc/modprobe.d/blacklist
$: echo blacklist ieee80211softmac >> /etc/modprobe.d/blacklist
$: echo blacklist ieee80211_crypt >> /etc/modprobe.d/blacklist
$: echo blacklist islsm >> /etc/modprobe.d/blacklist
$: echo blacklist islsm_pci >> /etc/modprobe.d/blacklist
$: echo blacklist islsm_device >> /etc/modprobe.d/blacklist
$: echo blacklist prism54 >> /etc/modprobe.d/blacklist

$: exit

We download wireless drivers from £com

http://www.3com.com/products/en_US/result.jsp?selected=6&sort=effdt&sku=3CRGPC10075&order=desc

Save the 3CRGPC10075_08_18_2005.exe fine in Wi-Fi directory we have created before

Now we must unzip 3CRGPC10075_08_18_2005.exe file:

$: unzip -a 3CRGPC10075_08_18_2005.exe

after we must change the dir with this command:

$: cd /Driver/Win2kXP

These are the most important commands you must do to load correctly the module:

$: sudo ndiswrapper -i mrv8335.inf

$: sudo ndiswrapper -l

you should see a message that says driver present, hardware detected

$: sudo ndiswrapper -m

$: sudo modprobe ndiswrapper

Thanks

Your wifi light on your laptop should be illuminated, and you're all set! Try running this to see if your wireless card is functioning properly

$: sudo iwlist scanning

Even if it doesn't detect any wireless networks in range, it will still tell you if linux is recognizing your wireless card properly. If you'd like a better way to scan for wireless networks, I'd suggest installing/using network-manager or wifi-radar.

Thanks
