Instructions for installing the custom madwifi can be found in our [:DebianEeePC/HowTo/Install#head-1e6b527ab177808ee304c69da8da7e44511719c1:Install ?HowTo].
If you're impatient and want to configure for wifi without encryption to a single access point, you can simply set it up as follows:
Simple open network
(File: /etc/network/interfaces) auto ath0 iface ath0 inet dhcp pre-up ifconfig ath0 up pre-up iwconfig ath0 essid "router ID"
Wpa supplicant with PSK
A more elegant solution to connect to one or more access points either with or without encryption is to use wpasupplicant. This is our recommended way to configure wifi for the Eee.
First, you have to "aptitude install wpasupplicant".
To configure for wifi to single access point with WPA(2)-PSK encryption, open a text file and paste this and save it as /etc/wpa_supplicant/wpa_supplicant.conf:
ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=0 ap_scan=1 fast_reauth=1 eapol_version=1 network={ ssid="ROUTER ID" psk="your password" priority=5 }
Then edit /etc/network/interfaces with this:
auto ath0 iface ath0 inet dhcp wpa-driver wext wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
Reboot and you have wifi
Wpa supplicant in roaming mode
For multiple access points, you'll want "roaming" mode. Starting with the previous example, in /etc/network/interfaces, change 'auto ath0' to 'allow-hotplug ath0', change 'wpa-conf' to 'wpa-roam'. Also change 'iface ath0 inet dhcp' to 'iface ath0 inet manual' and add a default connection method 'iface default inet dhcp'. When you're all done, your /etc/network/interfaces should look something like this:
auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug ath0 iface ath0 inet manual wpa-driver wext wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp
Now we are ready to define additional networks in /etc/wpa_supplicant/wpa_supplicant.conf. For example:
network={ key_mgmt=NONE }
This is a catch-all that will associate with any open access point within range using dhcp to connect.
You can add additional specific networks, each with their own ssid and specify either the type of encryption to use or specify key_mgmt=NONE for either no encryption or WEP. We can also assign id strings to these networks, so that if, for example, your home network is static, and the local cafe is dhcp, we can alter our files like so.
For WEP, you specify the key as follows:
ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=0 ap_scan=1 fast_reauth=1 eapol_version=1 network={ ssid="cafe" key_mgmt=NONE wep_key0=FFEEDD001122 id_str="cafe" } network={ ssid="home-router" psk=abcdefg id_str="home" }
And edit our /etc/network/interfaces as follows
auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug ath0 iface ath0 inet manual wpa-driver wext wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp iface cafe inet dhcp iface home inet manual address 192.168.1.5 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1
Tip: If you have trouble connecting to a network because it does not broadcast its ssid, add 'scan_ssid=1' to its network stanza.
Tip: Look in the [:DebianEeePC/HowTo/Install#head-322b9ade98a9e61ecd1609bc67f3d3779f9c9820:Troubleshooting] section of the main Install page if you have an error.
Using NetworkManager
If you like to use [:NetworkManager], delete eth0 and ath0 configuration from /etc/network/intefaces and install network-manager and network-manager-gnome (or network-manager-kde) packages.
