+====== ABANDONED PROJECT: Convert a Linux Box into a Wifi Router ======
+**Update 02/18/2013: it whould be a nice idea to retake this project to make it on the raspberry Pi...**
+**Don't read furhter!!!! I've abandoned this project without reaching a solution for this. There are other places and other solutions more suitable than this.**
+===== The problem =====
+In my fathers-in-law home there is a PC connected to the internet. However, there is no wifi router. I could do two things:
+  * Spend from 60 to 100 euros in buying one or,
+  * Convert his Ubuntu into a wifi hotspot
+I will investigate how to do the latter, because I think that it could be useful in the future.
+===== Making some searchs in internet =====
+Most promising link:

+===== What I've done =====
+I am using Ubuntu, so I've decided to install hostapd just out of the software center. The simpler, the better.
+In the configuration file, I've changed the following lines:
+<code>
+ssid=Put_the_name_you_want
+# in my case, the country code is Spain, in your case, choose what corresponds
+country_code=ESP
+hw_mode=g  # it were b by default
+wpa = 3
+wpa_passphrase=your_password_here
+wpa_key_mgmt=WPA-PSK WPA-EAP
+</code>
+Just after saving the data, run hostapd in debug mode:
+<code>
+/usr/sbin/hostapd -dd /etc/hostapd/hostapd.conf
+</code>
+===== If there are problems =====
+==== Appear the error "Unable to setup interface" ====
+Of course, always there are problems.
+I found an error ''Unable to setup interface''. One of the things I've tried is to start/stop the device:
+<code>
+ifconfig wlan0 down
+ifconfig wlan0 up
+</code>
+==== Appear the error "ioctl[PRISM2_IOCTL_PRISM2_PARAM]: Operation not supported" ====
+I've researched this point, and it seems that there must be a wpa_supplicant command that probably is failing in Ubuntu.
+Following the instructions here.
+http://ubuntuforums.org/showthread.php?t=532921
+It seems that the command wpa_supplicant must be run smoothly, but it doesn't.
