Le WiFi pendant l'installation
Si une connexion WiFi est requise au cours de l'installation de Gentoo, garder à l'esprit que le CD d'installation minimal Gentoo comprend un nombre limité de pilotes et ne propose que (et pas ) pour configurer les connexions WPA/WPA2/Enterprise.

Si le CD d'installation minimal ne contient pas les pilotes requis ou si vous préférez utiliser l'interface graphique de, mieux vaut alors choisir un CD d'installation différent, comme le CD System Rescue. Attention, en cas d'utilisation d'un CD d'installation autre que ceux proposés par Gentoo,il se peut que des précautions particulières doivent être prises.

Détection du matériel
Tout d'abord, il faut détecter les contrôleurs WiFi. ou sont des outils en ligne de commande qui peuvent être utilisés à cette fin.

Si un (LiveCD/USB) Linux est crée une connexion WiFi au démarrage :

Le pilote sera identifié sur une des lignes qui commencent par.

Copy the list of PCIID's that the command produces.

For USB devices, a similar approach can be taken. First obtain the list of detected USB devices on the system:

This command produces the PCI ID, manufacturer, make, model, and/or chipset of every USB device attached to the system. Of these, the chipset may be the most useful information. Searching the web for linuxwireless.org  is often the shortest way to find a USB NIC driver and firmware name.

Alternatively, can be used to obtain the necessary information:

This command produces a list of all drivers, regardless of the device being PCI or USB based.

Kernel
With the drivers identified, it is time to configure the Linux kernel.

WEXT
The "cfg80211 wireless extensions compatibility" option aka WEXT will support old and.

Device drivers
Next the right set of corresponding kernel options need to be enabled, based on the drivers and hardware detected previously. The recommendation is to build drivers as modules. Also be sure to enable AES cipher support in the kernel if the wireless network uses WPA or WPA2 encryption.

LED support
To enable LED triggers for different packet receive/transmit events, compile the kernel with the following options:

Firmware
In addition to the kernel driver, some chipsets also require firmware. If required, locate it on the following list and install it:

If the driver requires firmware but does not appear on the list, it will be necessary to download it manually and place it in.

Wireless supplicant
If the wireless network is set up with WPA or WPA2, then a [//en.wikipedia.org/wiki/Wireless_supplicant wireless supplicant] like wpa_supplicant or iwd needs to be used. For more information on configuring wireless networking in Gentoo Linux, please read the Wireless networking chapter in the Gentoo Handbook.
