Few weeks ago, during cleaning up, I found an old access point/router. I wanted to attach it to my network and do some tests, but I did not remember the password for configuring it through its web access page. I knew it had to be some default user/password but I did not succeed in my tries. I thought it was the right time to prepare a small dictionary attack. There are many powerful tools for this task but I used “Burp Suite” because I love it and I try to use it whenever I can. Furthermore is a perfect tool for understanding what happen behind the scenes during these kind of attacks.

I made the following video trying to explain this process. I hope you find it helpful.

If you want you can download the ‘combinator’ script used in the video -> combinator.rb.

When I bought my Raspberry Pi I also ordered this tiny usb wifi adapter (TP-LINK TL-WN725N) in order to play with my raspi everywhere. I got this adapter because  I read it worked out of the box, it was cheaper than others and it supported WiFi-N. As you may guess I am writing this post because the first advantage, the out of the box one, did not work for me.

Raspi with TP-LINK WN725N

I read some forums and it seemed that I had purchased a newer version of this adapter, the TL-WN725N v2. It needs a different driver, the Realtek 8188eu, which is not included by default in the Raspbian distributed by the official web site of Raspberry Pi. So, to sum up, I was able to find the driver source code and now I have a wireless raspi. If you have the same problem with this adapter, read the following lines to obtain directly the .ko object and you will be done. If you want you can download the driver source code (link at the end), compile and install it on your own.

To make it work just download the kernel object (.ko) file which is the compiled module driver for the kernel. I will be updating this section for different kernel versions.

Place the .ko object in the following path:


In my case it is the following path:


Last version of the rtl8188eu driver includes a firmware file called rtl8188eufw.bin you have to place this file under:


Now execute the following commands

depmod -a

modprobe 8188eu

We are done. You should see now the new interface (wlan0 normally) when the device is connected.
