+WPS and OpenWRT

+When hearing WPS_ i always think of the worst idea in network security. *'Hey,
+how about changing a long key with a minimum length of 8 characters to
+something like... 4 numbers! And with that number you get the original
+password! GENIUS'* . But WPS consists of more than this shitty idea. It also
+provides a means of attaching shitty devices to wifi with 'one touch of a
+button'[#]_. That is why quite a lot of current routers have the WPS-Button to
+easily connect such devices (namely wifi printers and scanners).
+
+It **just works** with stock firmware but of course i am running a
+Frickelsystem_ on my TP-Link router. On OpenWRT it *might* work out of the box
+with the latest and greatest unstable release but in my case i
+needed to replace some packages to make it work.
+
+Here is what i needed to do:
+
+.. code-block:: bash
+  
+    opkg update
+    opkg install hostapd-utils --force-override
+    opkg install wpad --force-override
+    vi /etc/config/wireless
+      # add 'option wps_pushbutton 1' to every 'config wifi-iface' section
+    
+    #testing the shit
+    wifi
+    hostapd_cli interface wlan0 wps_pbc 
+
+After running the last command, press the WPS button on your printer. The wifi
+should now glowing in the correct color.
+The WPS button on your router should now also be working if the stars are
+alligned correctly.
