In order to help we need more information. First of all which of the Sabayon Linux systems you installed - gnome, kde, xfce etc.. Secondly the specifications of your machine - especially important is the wireless. You can find a lot of information by opening a terminal (I'm assuming you've never done anything like this before so don't be offended if you have) and you will find that in your systems menu. Type in "su" (without the quotation marks) and press enter. Enter your root password and press enter again. Type in "lspci" (without the quotation marks") press enter and copy the output. Then type in "lsusb" (without the quotation marks) press enter and copy that output. Once you have the information safely copied type "exit" (without the quotation marks) press enter then repeat that.
You will then have some information to post here.
