You can use the "madwifi" drivers provided for the Atheros card (DWL-G650), this script will download and install the files needed.

#!/bin/bash

cd /usr/src
rm -Rf /usr/src/madwifi

cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/madwifi co madwifi

cd /usr/src/madwifi

#Use for 32-bit OS
make

#Use for 64-bit OS
#make TARGET=x86_64-elf TOOLPREFIX=""

make install

You can test the kernel module with:

modinfo ath_pci

Next, insert this code into /etc/modprobe.conf

alias ath0 ath_pci

Then edit /etc/sysconfig/network-scripts/ifcfg-ath0

IPV6INIT=no
ONBOOT=no
USERCTL=yes
PEERDNS=yes
TYPE=Wireless
DEVICE=ath0
BOOTPROTO=dhcp
HWADDR=
IPADDR=
NETMASK=
GATEWAY=
DOMAIN=
DHCP_HOSTNAME=
ESSID='put_your_essid_in_here'
CHANNEL=1
MODE=Managed
RATE=auto

You can control the device with:

ifup ath0
ifdown ath0

Thats enough to get you up and running, but now you need to secure it....

For WPA Security, download this file: http://hostap.epitest.fi/releases/wp...t-0.4.3.tar.gz

tar -xzvf wpa_supplicant-0.4.3.tar.gz -C /usr/src
cd /usr/src/wpa_supplicant
cp defconfig .config

Make the following changes in .config file

CONFIG_DRIVER_MADWIFI=Y      <-- uncomment this
CFLAGS += -I../madwifi       <-- change this

Now save the file and build the source code:

make clean
make
make install

Now edit /etc/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

network={
    ssid="put_your_essid_in_here"
    scan_ssid=1
    proto=WPA
    key_mgmt=WPA-PSK
    psk="insert_secret_passphrase_in_here_for_wpa"
}

You may need to check if /var/run/wpa_supplicant directory exists yet.

Now to automate things a little:
Edit /etc/sysconfig/network-scripts/ifup-wireless

Put this code at the VERY BOTTOM.

echo -e \\n\\nInitialising \'wpa_supplicant\' WIFI Security....\\n
kill -9 `ps -e | grep wpa_supplicant | cut -f2 -d " "` 2>/dev/null
/usr/local/sbin/wpa_supplicant -Bdw -i ath0 -c /etc/wpa_supplicant.conf -D madwifi

Now ifup ath0

That should get you up and running... remember to check your logs

dmesg
tail -n 50 /var/log/messages

Hope that helps..

This assumes the card has the atheros chip set. Mine has the prism54 chipset.

Check your card by using /sbin/lspci command. Assuming it is the atheros chipset then the madwifi drivers should work as described above. If it has a different chip set you will need to find drivers to match or use ndiswrapper or driverloader.

ok went good up to the point of ( make ) then i started getting errors.

[kg4cbk]

If you don't post the specific error messages most people on this list won't be able to access your system and check what went wrong.

[magicdawg29]

[root@24-183-201-62 madwifi]# make
Checking if all requirements are met... ok.
mkdir -p ./symbols

fix with:

yum install sharutils

[magicdawg29]

ok here is next error:

[root@24-183-201-62 madwifi]# modinfo ath-pci
modinfo: could not find module ath-pci


Plus when you tell me to edit files i dont know how to do that either.

You guys are being a REALLY big help tho, THANKS

[magicdawg29]

it is still same whith the correct input

modinfo ath_pci

[kg4cbk]

Did you run the

make install

command?

To edit files there are a number of editors available. gedit may be the easiest for you to use. vi is an editor you will find on almost all unix systems.

[magicdawg29]

Then edit /etc/sysconfig/network-scripts/ifcfg-ath0

That file is not ine there. Might i have done ANOTHER THING WRONG?

[Butt-Ugly]

no, you need to 'create' that file and add the details to it.
