The majority of wireless ethernet cards are currently supported by
either their respective drivers in the Linux kernel or using their
Windows drivers via ndiswrapper. Sabayon Linux should automatically
detect the correct module/s for your computer's wireless ethernet card.
If this isn't the case (You don't have a device called eth0 or
eth1 after typing ifconfig -a as root in terminal) then type the
command lspci in a root terminal to identify your PCI based wireless ethernet card or type lsusb -v in a root terminal to identify your USB based wireless ethernet card.
The information you are looking for is the line that follows on
from Network controller: , for PCI Based wireless ethernet cards.
The information you are looking for is found after the
idVendor, iManufactur and iProduct lines , for USB Based wireless
ethernet cards.
From those lines identify the manufacturer and model of your
wired ethernet card, and the use Google or your favourite search engine
to identify (add linux or gentoo as one of the search terms) which
kernel module you manually need to load or which drivers you may need
to install to get a working kernel module, or whether you are best to
use ndiswrapper.
Common native wireless chipsets / devices that have native
drivers (either in kernel or 3rd party) include Aironet (airo), Hermes
(hermes), Broadcom (bcm43xx), acx, adm8211, hostap-driver , Intel
(ipw2100, ipw2200, ipw3945), linux-wlan-ng, Atheros (madwifi-ng),
Orinco (orinoco), Prism (Prism2, prism54) , Realtek 2x00 range (
rt2400, rt2500, rt2561, rt2570, rt2x00), Realtek 818x range (rtl8180,
rtl8187) , Netgear (wg511t) and Zydas (zd1211).
The list of wireless chipsets / devices that are supported with ndiswrapper is found at http://ndiswrapper.sourceforge.net/mediawiki/index.php/List .  
Once you have identified the module you need to load, install the correct driver package by using emerge.
Mostly likely either by typing emerge drivername  in terminal (as root) or by typing emerge ndiswrapper  in terminal (as root) .
Before installing the drivers or ndiswrapper, type uname -a to identify your Sabayon installation's current Linux kernel , then type ls -l /usr/src/linux and ensure that the arrow points to the same kernel version reported by uname. If not type rm /usr/src/linux in terminal (as root) to delete the link and recreate by typing ln -s /usr/src/linux/linux-kernelversion-kerneltype /usr/src/linux
in terminal (as root) . (where kernelversion is numerical version
number of your kernel from uname and kerneltype is either gentoo or
sabayon from uname).
If using ndiswrapper type ndiswrapper -i /path/to/windowsdriver.inf followed by ndiswrapper -m to correctly install the windows driver in ndiswrapper.
Once the driver or ndiswrapper is installed then load it by typing (in root shell) modprobe modulename
(where modulename is the name of linux kernel module for your
computer's wireless ethernet device / card). Then check that it is
loaded by typing (in root shell) lsmod | grep modulename (where modulename is the name of linux kernel module for your computer's wired ethernet device / card).
If the module is loaded then you will see the modulename returned in console, now you should be able to type ifconfig -a
(as root) in terminal and a device called ethX (where X is mostly
likely 0 or 1, unless your are using madwifi and then it is athX) is
shown in console / terminal/
If not please type dmesg | tail -n 50 (as root) in shell and paste the output at http://rafb.net/paste or http://pastebin.ca. Then seek help on the Sabayon forums or IRC and attach the URL for the dmesg paste.

I just put Sabayon on my laptop.  I have Broadcom for wirless with an intell pro wireless card.  Any ideas on how to get my wireless to work?
 
I'm really new to this, so any help would be great.
