Configuring your network
It's important to ensure that you will be able to connect to your local-area network after you reboot into Funtoo Linux. There are three approaches you can use for configuring your network: NetworkManager, dhcpcd, and the Funtoo Linux Networking scripts. Here's how to choose which one to use based on the type of network you want to set up.
Most wifi cards require firmware, some do not, such as netgears wg311t atheros AR5212/AR5213.
(chroot) # emerge linux-firmware
For laptop/mobile systems where you will be using Wi-Fi, roaming, and connecting to various networks NetworkManager is strongly recommended. See the net-misc/networkmanager package for steps involved in setting up NetworkManager.
wpa_supplicant is a good choice for home wireless network connections where roaming is to a minimum. See the net-wireless/wpa_supplicant package for steps involved in setting up wpa_supplicant.
Desktop (Wired Ethernet)
For a home desktop or workstation with wired Ethernet that will use DHCP, the simplest and most effective option to enable network connectivity is to simply add
dhcpcd to the default runlevel:
(chroot) # rc-update add dhcpcd default
When you reboot,
dhcpcd will run in the background and manage all network interfaces and use DHCP to acquire network addresses from a DHCP server.
If your upstream DHCP server is dnsmasq, it can be configured to assign addresses via mac address to make servers on DHCP feasible.
Server (Static IP)
Funtoo Networking Scripts
For servers, the Funtoo Linux Networking scripts are recommended. They are optimized for static configurations and things like virtual ethernet bridging for virtualization setups. See Funtoo Linux Networking for information on how to use Funtoo Linux's template-based network configuration system.
Iproute2 / Net-Tools
A lesser prefered way to configure static ip addresses and routes is by the legacy net-tools, or iproute2 package. See: sys-apps/iproute2
