1. Update the firmware on your PS3. This can be achieved from GameOS with the Software Update function in settings. This must be v1.6 or newer.
   
   
2. Download the new PS3 Wi-Fi enabled kernel (if you are upgrading a prior intall). This is found via your YDL.net Enhanced account or the public mirrors. You will need kernel-ps3-2.6.16-20070425.ydl.3.ppc64.rpm or newer.
   
   
3. Install the new kernel;

   rpm -ivh /path/to/kernel-ps3-2.6.16-20070425.ydl.3.ppc64.rpm [ENTER]

   Edit /etc/kboot.conf. Copy the default kernel line in kboot.conf, then modify the original line to point to the new kernel: For example, if your default kernel line is:

   ydl='/dev/sda1:/vmlinux-2.6.16-20061110.ydl.2ps3 initrd=/dev/sda1:/initrd-2.6.16-20061110.ydl.2ps3.img (wrap)
   root=/dev/sda2 video=ps3fb:mode:3 rhgb'

   ... the modified entry would like this:

   ydl='/dev/sda1:/vmlinux-2.6.16-20070425.ydl.3ps3 initrd=/dev/sda1:/initrd-2.6.16-20070425.ydl.3ps3.img (wrap)
   root=/dev/sda2 init=/sbin/init video=ps3fb:mode:3 rhgb'
   
   oldydl='/dev/sda1:/vmlinux-2.6.16-20061110.ydl.2ps3 initrd=/dev/sda1:/initrd-2.6.16-20061110.ydl.2ps3.img (wrap)
   root=/dev/sda2 video=ps3fb:mode:3 rhgb'

   ... where 'oldydl' is your original kernel.
   
   

   Reboot.
