Networking :: MADWiFi Driver with Kernel 2.4.26



Having trouble compiling the madwifi driver http://madwifi.sourceforge.net/ for my D-Link DWL-G630 wireless card with the Atheros chip. I installed the kernel source, and there is a symbolic link from /usr/src/linux-2.4.26 to /usr/src/linux, and there is a sybmolic link from /usr/src/linux-2.4.26 to /lib/modules/2.4.26/build, but I am still getting the following error, and I do not know what is causing it. I have already tried the madwifi forum, and many people tried to help me, but I have come to the conclusion that it is a problem with Damn Small Linux and not a problem with the madwifi driver. Does anybody know what would cause this error on Damn Small Linux with the 2.4.26 kernel?

dsl ~/madwifi $ -> make KERNELPATH=/usr/src/linux-2.4.26 KERNELRELEASE=2.4.26
Checking if all requirements are met... ok.

Here is more detailed output that I got from adding -d to the make command, which does just that; makes more detailed output from make.

lub997,
You should not have to compile the madwifi driver at all, it's already in DSL - /lib/modules/2.4.26/net/ath_pci.o

But check to make sure your D-Link G630 does, indeed, have the Atheros chipset.  There are some G630's, versions A and B apparently, which have the Texas Instruments chipset.  There is a dedicated Linux driver for this from http://acx100.sourceforge.net
DSL does not have this driver, so you would need to compile it ... or ndiswrapper could be used instead.
You are correct. I do have ath_pci.o in /lib/modules/2.4.26/net/, and I was completely unaware of it. Now that I know I have the ath_pci.o module, how do I use it? I did check already, and I do have the version C2 Atheros chipset. <<lspci>> confirmed that it is Atheros, and the back of the card says it is version C2. When I boot up DSL it automatically recognizes my regular non-wireless ethernet pcmcia card and it works great, but using my wireless card with the Atheros chip I go into Firefox and am unable to get any websites. Now that I know I already have the driver, what do I need to do to make it work?
I can't give you the complete instructions, just pointers.
See http://madwifi.sourceforge.net/dokuwik....0c2848f
You need to modify /etc/network/interfaces so that hotplug will bring up interface "ath0" when it detects your card.

Run "lsmod" to see if DSL has automatically loaded the ath_pci module.  If not, load it manually -
modprobe ath_pci
In fact, it's probably a good idea to reload it now that you have changed the /etc/network/interfaces file ... or maybe even reboot.

Now use iwconfig to (manually) set things up.  I'm not familiar with iwconfig, but it's going to be something like -
iwconfig ath0 ......
Obviously you need to define your SSID, WEP key, and wireless mode.

Once you know it works, I think the configuration information can be added to /etc/network/interfaces so that your wireless connection will happen automatically when your card is inserted.
