Re: Using wireless networking

I have an acer 5002 notebook with an AMD Turion64 processor. I have
installed Ubuntu linux (Breezy Badger), but noticed that the built-in
wireless network wasn't listed as being compatible. Now, I also noticed
that the Linksys WPC54GS PCMCIA wireless network card was compatible,
so I bought one. Problem is, I figure that it's not working because of
the 64 bit archetecture. Power light's on in the card, I rebooted, and
I can see the card in my Device Manager. I can't see it in my
network-admin, and nothing is listed under iwconfig. I've tried
different ways of using ndiswrapper, but none of the seem to work at
all, so I've started from scratch, re-installed everything, and have a
blank slate. Please, point me in the right direction, or something.
Thank-you.


The first thing is to determine if the CardBus system is recognizing the WPC54GS. See if the output of 'lspci -v' lists it. If not, you will have to consult the PCMCIA group.

If the card is recognized, you will probably need to use ndiswrapper (see below). If you are using the 64-bit kernel, you will need the 64-bit version of the Windows driver, which I think is named bcmwl564.sys.

Follow the instructions at http://ndiswrapper.sourceforge.net/mediawiki/index.php/Installation to install ndiswrapper.

There is a project that is writing a native driver for the Broadcom chips such as are found in the Linksys WPC54GS. I'm using it now on a Linksys WPC54G. You will find the project at http://bcm43xx.berlios.de/; however, it is not easy to use if you want to use encryption. For open networks, it is fairly easy to implement. This driver will work with 64-bit systems. You will still need the Windows driver as the firmware for the card comes from that driver.

Good luck. Wireless networking is one of the more difficult things to implement in Linux.
