- Attacks on the WEP protocol by Erik Tews, December 15, 2007. This thesis summarizes all major attacks on WEP. Additionally a new attack, the PTW attack, is introduced, which was partially developed by the author of this document. Some advanced versions of the PTW attack which are more suitable in certain environments are described as well. Currently, the PTW attack is fastest publicly known key recovery attack against WEP protected networks.
- WPA Migration mode: WEP is back to haunt you... by Leandro Meiners and Diego Sor. Migration mode, from Cisco, allows both WEP and WPA clients on the same AP. Besides the fact that the WEP key can be cracked easily, they also bypass the additional security settings offered by Cisco. Here is the slides of the presentation and the paper.

There are hundreds of books about wireless. This section makes no attempt to list all the available books regarding wireless. Rather, it lists books which will likely be of specific interest to the readers of the wiki. If you have read books that you think should be included here, please post information about them to the forum.
Please keep in mind that books are always dated to some degree. If you are looking for 100% up to date material and information then the Internet is your friend.

A common question on the forums is how to compile a new kernel. This section attempts to identify links to documents, HOWTOs and similar which you may find helpful in this regard.
Another question that comes up is how to compile a single driver module. Here are the basics:
First, cd to the directory which contains the source files to be compiled. It assumes you have patched the source if required.
make CONFIG_ZD1211RW=m -C /lib/modules/`uname -r`/build M=`pwd` clean make CONFIG_ZD1211RW=m -C /lib/modules/`uname -r`/build M=`pwd` modules make CONFIG_ZD1211RW=m -C /lib/modules/`uname -r`/build M=`pwd` modules_install depmod -ae
In the above:
- “CONFIG_ZD1211RW=m” If the module is not “enabled” in the kernel config then you need to set the variable for that specific module to “m” for module. IE Enable it. It is not always required and must be changed to the specific driver you are trying to compile.
- “-C” This has to be set to the location of your kernel source tree. “-C /lib/modules/`uname -r`/build” will typically work correctly.
- “M=” This has to be set to the location of the source files to be compiled. If you have already changed to the directory containing the source files then “M=`pwd`” will typically work correctly. pwd specifies the current directory you are in.
There are some considerations regarding installing a single module. You will need to ensure that the new module overwrites the existing one in /lib/modules. Sometimes it ends up being placed in a different location in the /lib/modules tree. If this happens then be sure to delete to the old version and run “depmod -ae”.
Alternatively, manually copy the newly created .ko kernel modules over the existing ones located in the /lib/modules tree.
