Revision as of 16:14, 25 January 2007
This is based on my wireless dongle (Safecom SWMULZ-5400) that I have running and that uses the zd1211 chip, support for this chip is enabled in the 2.6 kernel - andre kindly maintains the upkeep of this kernel and the bootloader to install it on your system. I'm using an LS1(ppc) here, by the way. There is support for other chipsets in the kernel I believe - airo, bcm43xx, hermes, hostap, ipw2100, orinocco, prism54
There is a list of devices that use the zd1211 chipset here

Requirements
- Kernel that supports your dongle
- More Linux knowledge than me - (Bauldrick)
Installation
apt-get install wireless-tools
If you want WPA/2 support
apt-get install wpasupplicant
You'll be needing the firmware for your device (check for latest version - currently 1.3)
mkdir /lib/firmware cd /lib/firmware wget http://downloads.sourceforge.net/zd1211/zd1211-firmware1.3.tar.bz2?modtime=1167489439&big_mirror=0 tar -jxvf zd1211-firmware1.3.tar.bz2 mv zd1211-firmware zd1211
Now if you plug your device in you should see it (something similar to below)
dmesg
ieee80211_crypt: registered algorithm 'NULL' ieee80211: 802.11 data/management/control stack, git-1.1.13 ieee80211: Copyright (C) 2004-2005 Intel Corporation <jketrenol> zd1211rw 1-2:1.0: firmware version 4725 zd1211rw 1-2:1.0: zd1211b chip 0ace:1215 v4810 high 00-02-72 AL2230_RF pa0 g--- zd1211rw 1-2:1.0: eth1 usbcore: registered new interface driver zd1211rw
WEP Interfaces
Things won't work at the moment, we need to add a few things
pico /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth1
iface eth1 inet static
address 192.168.0.103
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1
wireless_essid <YourNetworkName>
wireless_key <YourSecurityKey>
auto eth0
iface eth0 inet static
address 192.168.0.101
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.1
WEP Start
This starts the dongle at boot (don't know why I did it like this - I think you need just create a file with ifup & iwconfig)
pico /etc/init.d/wireless
#! /bin/sh
# /etc/init.d/wireless: start and stop wireless dongle
case "$1" in
start)
OK="0"
dmesg | grep -q eth1 && OK="1"
if [ "$OK" == "1" ] ; then
ifup eth1
iwconfig eth1 essid <YourNetworkName>
fi
echo -n "Starting wireless dongle"
;;
stop)
OK="0"
dmesg | grep -q eth1 && OK="1"
if [ "$OK" == "1" ] ; then
ifdown eth1
fi
echo -n "Stopping wireless dongle"
;;
# restart)
# ;;
#
# *)
# echo "Usage: /etc/init.d/wireless {start|stop|restart}"
# exit 1
esac
exit 0
chmod a+x /etc/init.d/wireless
WPA Interfaces
pico /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
network={
ssid=<YourNetworkName>
psk=<YourSecurityKey>
proto=WPA
priority=5
}
If you want to use WPA2, change proto=WPA to proto=WPA2
pico /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth1
iface eth1 inet static
address 192.168.0.103
netmask 255.255.255.0

gateway 192.168.0.1
pre-up wpa_supplicant -Bw -ieth1 -c/etc/wpa_supplicant.conf -Dwext
post-down killall -q wpa_supplicant
auto eth0
iface eth0 inet static

gateway 192.168.0.1
Installation cont
Putting eth1 before eth0 in /etc/network/interfaces should bring up your wireless dongle (eth1) before the wired ethernet (eth0), but it doesn't for me? So, I had to alter the network start file -
pico /etc/init.d/networking
case "$1" in
start)
doopt spoofprotect yes
doopt syncookies no
doopt ip_forward no
echo -n "Configuring network interfaces..."
ifup -a
ifup eth1
echo "done."
;;
stop)
if sed -n 's/^[^ ]* \([^ ]*\) \([^ ]*\) .*$/\1 \2/p' /proc/mounts |
grep -q "^/ nfs$"; then
echo "NOT deconfiguring network interfaces: / is an NFS mount"
elif sed -n 's/^[^ ]* \([^ ]*\) \([^ ]*\) .*$/\1 \2/p' /proc/mounts |
grep -q "^/ smbfs$"; then
echo "NOT deconfiguring network interfaces: / is an SMB mount"
elif sed -n 's/^[^ ]* \([^ ]*\) \([^ ]*\) .*$/\2/p' /proc/mounts |
grep -qE '^(nfs[1234]?|smbfs|ncp|ncpfs|coda|cifs)$'; then
echo "NOT deconfiguring network interfaces: network shares still mo$
else
echo -n "Deconfiguring network interfaces..."
ifdown -a --exclude=lo
ifdown eth1 --exclude=lo
echo "done."
fi
;;
force-reload|restart)
doopt spoofprotect yes
doopt syncookies no
doopt ip_forward no
echo -n "Reconfiguring network interfaces..."
ifdown -a --exclude=lo
ifdown eth1 --exclude=lo
ifup -a
ifup eth1
echo "done."
;;
*)
echo "Usage: /etc/init.d/networking {start|stop|restart|force-reload}"
exit 1
;;
esac
exit 0
Test to see if its working
ifup eth1 dmesg | grep eth1
If you are using WEP you may still see
zd1211rw 1-1:1.0: eth1 ADDRCONF(NETDEV_UP): eth1: link is not ready
If this is the case you will need to do
iwconfig eth1 essid <YourNetworkName>
Do another
dmesg | grep eth1
Hopefully you should now see
zd1211rw 1-1:1.0: eth1 ADDRCONF(NETDEV_UP): eth1: link is not ready ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
OK - Now you should be able to connect to your wireless dongle on the address you specified in /etc/network/interfaces under eth1 If that works restart
reboot
Once it boots try connecting to your wireless dongle on the address you specified in /etc/network/interfaces under eth1. Hopefully you get a connection
Things To Do
Currently I can't connect to the internet (apt-get etc...) whilst I have both wired ethernet port (eth0) and wireless (eth1) "up" You will need to do
ifdown eth0
and then everything should be good to go. Obviously this means that the ethernet port can't be used for anything else (must be able to fix this?)
Put that into the start script, but becareful that eth1 has a connection, else you'll be locked out? (My box just reverted to 2.4, and so couldn't connect)
