Wifi with kernel 2.6

WPA-tkip algorithm support

K-Team SA,
J. Tharin


version 1.0: 20090306 

required hardware: KorebotLE with kernel 2.6

required softwares:
  - development toolchain 2.6: http://ftp.k-team.com/korebot/toolchain-2.6-betaV0.1/
  - wpa-tkip_kernel2.6.23.1-kb1.tar.bz2

Here enclosed you will find the modules to add to have the WPA/TKIP encryption,
 with the procedure as follows:

1) If you have the kernel version 2.6.23.1-kb1 on your korebot (you can check with the command uname -a)
  you can use the file included; go to step 2).
 
  If your kernel is different you'll have to build the module:
    a) Follow the instructions for building the kernel:
      http://ftp.k-team.com/korebot/toolchain-2.6-betaV0.1/common_files/kernel_build.txt
  
    b) When you run "make menuconfig", at the menu choose:
         "Networking --> Wireless --> IEEE 802.11i TKIP encryption" 
  
    c) and activate as module <M>
    
    d) then continue the instruction of a) "make -j3"

    e) after "make install", use the file copied in the dist directory (see below) for the next step 2)


    (e.g.) /home/jtharin/projects/kernel2.6/development/dist/lib/modules/2.6.23.1-kb1/kernel/net/ieee80211/ieee80211_crypt_tkip.ko


   
 
2) copy the modules from the enclosed archive (for other kernel version, adapt path)
 
    ieee80211_crypt_tkip.ko   to  /lib/modules/2.6.23.1-kb1/kernel/net/ieee80211/
 
    michael_mic.ko   to   /lib/modules/2.6.23.1-kb1/kernel/crypto/ 
     
 
3) update the modules table: depmod -a
 

Here after is an example of settings files:
