Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Running Slackware and installing Netgear WG511 wireless card I have followed all instructions in a tutorial to get my wireless card running, everything has worked up till now (so far I have installed ndiswrapper, used it to create the right driver for my wireless card, which outputs the correct info on ndiswrapper -l [driver installed, hardware present]) but when I try "modprobe ndiswrapper", which is supposed to create wlan0 and connect my wireless card, it does not seem to do anything at all. I tried doing it several times, removing it with rmmod and recreating it but everytime I run iwconfig or ifconfig, no changes have been made.
I've made it this far and I've tried about 4 different driver versions which all worked up until this point.
I'm sorry Lenard, to put myself at an even lower level haha, but being brand new at linux I'm having a hard time finding the ifcfg-wlan0 file, or is it something I have to create, and if so...where?
Plus, I got the idea that ndiswrapper would do this because thats what all tutorials say, even in the link you gave me, I quote
"To load the module type modprobe ndiswrapper. If you get no error, the driver should now be loaded. You can verify this by checking the system log produced by dmesg. If the driver is loaded successfully, you should see a message in the system log
ndiswrapper version <version> loaded
Make sure the version <version> here matches the version of ndiswrapper package that you downloaded and installed. If you get a different version, you have an old version of package, which you should uninstall, and then go back to step 1."
I included that last section because I was wondering if my ndiswrapper may not be workin correcty because its ver 1.15, this is because it was easer for me to just install an earlier version that is compatible with gcc 3.3, then to upgrade to 3.4, which I dont know how to do.
As long as it's "version 1" (not "revision 1"), you're in good shape. That's a Prism54 chipset, driver available at http://prism54.org/
...ndiswrapper IS a necessary element of Linux.
I think we've had this conversation before ... ndiswrapper, VMware, Wine, etc. will never be a part of any system I own or service. I maintain a dual boot system for those occasions when I need to run a Windows program.
You can find the chipset using "lspci -v" as root. Also, take a look in the ndiswrapper wiki. http://ndiswrapper.sourceforge.net/m....php/Main_Page
They have an hcl list with URLs to the windows drivers that work the best with ndiswrapper. Sometimes the driver supplied with the device will not work with ndiswrapper.
The ifcfg-wlan0 file is most likely in /etc/sysconfig/network/, however I don't know if slackware uses that configuration file. Slackware may instead set up the device directly using a script in /etc/init.d.
On my SuSE Amd64 laptop, I had a problem with the version of ndiswrapper that was supplied by SuSE 10.1's package. I uninstalled that version and installed from the ndiswrapper source I used for SuSE 10.0. My particular problem was that the "modprobe ndiswrapper" command would fail. However, there was an error message displayed, which you didn't see, so using an earlier version of ndiswrapper may not be a solution in your case.
Make sure that you run the "ndiswrapper -m" command after wrapping the Windows ndis driver. This will produce the modprobe.conf alias line. It won't hurt to run it again if you aren't sure. If the line already exists, it won't add it twice. Also, there are a couple commands I will sometimes try. "ldconfig" and "depmod -a". The ldconfig command probably won't do anything in your case. I don't think that ndiswrapper installs a library file. The "depmod -a" might help make sure that the ndiswrapper module will get loaded in the future.
After you "modprobe ndiswrapper", does a "lsmod" listing show the ndiswrapper kernel module? One of the wireless tools programs is "iwlist". The command "iwlist wlan0 scan" should scan for and list Access Points. If it does, your wireless device is probably working. However, if wlan0 doesn't exist, I guess this won't help. Try "ifconfig" and see if there is a wireless device by another name.
Distribution: RHEL/CentOS/SL 5 i386 and x86_64 pata for IDE in use
Since you have a Netgear WG511 card the ndiswrapper module is not needed, follow the link provided by erich and download the FullMAC firmware file Version 184.108.40.206 (for ISL3880 and ISL3890) and rename the file to isl3890. This file (isl3890) is placed someplace like /lib/firmware or /etc/firmware (varies by distro used).
Make sure you have the already built modules (orinoco_cs and prism54) they can be found in the /lib/modules/<kernel-version_number/kernel/drivers/net/wireless/ location, the prism54 module should be in the prism54 sub-directory.
Sample enties for the Netgear WG511 card in /etc/modprobe.conf are;
alias eth1 orinoco_cs
alias wlan0 prism54
Others have already provided the information on where to look for or to place the sample ifcfg-wlan0 I provided earlier. The same sample configuration file can be used as ifcfg-eth1 instead, just change the one line to read eth1 instead of wlan0 in the example and save it as ifcfg-eth0
