re: How to configure toshiba laptop to connect to the internet

Hi,

I have a Toshiba A75 which also has the Atheros wireless built in. I use Slackware, not Fedora, but the steps should be similar. It was pretty easy getting wireless working. Let me know if it works for you:

On Linux, the Madwifi project (Multiband Atheros Driver for Wifi) has developed a driver for Atheros. To get wireless working:

1. Get the madwifi code from CVS. This is the command for the stable tree (worked for me)
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/madwifi co madwifi

You could also check out the WPA tree
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/madwifi co -rWPA madwifi

Also, prebuilt rpms are available for Fedora so you could get those:
http://dag.wieers.com/packages/kerne...e-madwifi/?M=D

2. Build the package (assuming you didn't get the rpms). Fyi the package comes with a comprehensive readme file. However, doing "make" then as root "make install" (or checkinstall if you have checkinstall installed; checkinstall allows you to create rpm or deb or tgz packages easily) should do the trick.

The package includes three important modules:

wlan
ath_pci
ath_hal

The wlan module provides support for 802.11 wireless, the ath_pic is the driver for the pci/cardbus device, and the ath_hal is a hardware abstraction layer. The hardware abstraction layer isn't open source; the need/rationale behind this is explained elsewhere and I won't go into that here.

The modules need to be loaded into the kernel; this can be done with insmod or modprobe or included in a script.

3. Use the wireless extensions tools to bring up the connection.

The wireless extensions (iwconfig) can then be used to configure the wireless connection. The connection will be "ath0" not "eth0". This worked for me.

# make sure the kernel modules are loaded
insmod wlan
insmod ath_pci
insmod ath_hal

# may not need to bring ath0 down first, but it can't hurt.
ifconfig ath0 down
ifconfig ath0 up

# this will scan for available wireless access points
iwlist ath0 scan

#iwconfig commands
iwconfig ath0 essid "your essid here"
# can set more parameters now too (channel, frequency,etc). see man iwconfig for details

# use dhcp to assign ip address etc
dhcpcd ath0

may have to assign a default route with the route command, but I didn't seem to have to do this.

Once this is working manually the commands can be put into /etc/rc.d/rc.local to run when the computer is started. I had better luck with
this over the /etc/rc.d/rc.wireless script that came with Slackware. Not really sure how/where to put these in Fedora.

Also, the Mepis live cd comes with integrated support for Atheros wireless, so you might want to check that out too. The Madwifi project has an unofficial faq at <http://www.mattfoster.clara.co.uk/madwifi-faq.htm>
