It is easy to turn an old notebook into a wireless AP. I don't know Fuduntu. I
use Debian, therefore the following instructions are Debian centric but can
easily be adapted to other distributions as well. What differs are the
package names and the location of the configuration files.
The following packages are needed:
In the following it is assumed that your wireless connection is
your wired one
eth0, you need to adapt it to your setup.
First you need to set up the bridge. Remove or comment out any entries that
eth0 in the file
/etc/network/interfaces and add the
Setting up the bridge
iface br0 inet dhcp
bridge_ports eth0 wlan0
pre-up ifconfig eth0 0.0.0.0 up
pre-up ifconfig wlan0 0.0.0.0 up
pre-up brctl addbr br0
pre-up brctl addif br0 eth0
post-down ifconfig wlan0 0.0.0.0 down
post-down ifconfig eth0 0.0.0.0 down
post-down brctl delif br0 eth0
post-down brctl delbr br0
Setting up hostapd
hostapd daemon to use a particular configuration file: Ensure the
following line is present in
Now you can set up your wireless network. Here I just provide an example
configuration. The exact values depend on your hardware, which encryption is
supported and your environment (e.g. surrounding networks). Open the file
/etc/hostapd/hostapd.conf and ensure the following values are set.
Important here is to select a driver that works with hostapd and your
hardware. The SSID is a random string to identify your network. The channel
should be picked, so that there is the least interference with the surrounding
networks. The passphrase should be at least eight characters long.
For the other options read the provided configuration file. It is heavily
commented and almost serves as a manual.
Starting the access point
Now you can bring up the interfaces
and start the access point
Another possible solution
The FreeBSD distribution pfSense is a firewalling and routing platform with AP functionality. Everything can be set up nicely using a GUI. Behind the scenes it also uses
hostap, but the configuration is simpler and more user friendly. The drawback of using pfSense is that you should not do your regular computing on the same box, pfSense expects to be running on a dedicated system, although this is not a technical requirement.
