You can check if the firmware is included in the kernel config:

grep -i wifi /usr/src/linux/.config

If CONFIG_EXTRA_FIRMWARE is set, then a firmware is included. You just
need to check if it's the right one for your wifi chip.

Otherwise you can set some options in /etc/genkernel.conf.

Set MENUCONFIG="yes" to be able to configure your kernel by yourself
and set CONFIG_EXTRA_FIRMWARE there.

Or instead you can set those options in /etc/genkernel.conf:
FIRMWARE="yes"
FIRMWARE_DIR="/lib/firmware"
FIRMWARE_FILES=""

I have't tried the latter, because I usually configure my kernel by
myself with menuconfig. I only use genkernel as an easier way to have
the kernel compiled, installed and the initrd built.

As already pointed out, this driver does require firmware to run. See below.

drivers/net/wireless/intel/iwlwifi/Kconfig:1,31
config IWLWIFI
tristate "Intel Wireless WiFi Next Gen AGN -
Wireless-N/Advanced-N/Ultimate-N (iwlwifi) "
depends on PCI && MAC80211 && HAS_IOMEM
select FW_LOADER
---help---
 Select to build the driver supporting the:

 Intel Wireless WiFi Link Next-Gen AGN

 This option enables support for use with the following hardware:
Intel Wireless WiFi Link 6250AGN Adapter
Intel 6000 Series Wi-Fi Adapters (6200AGN and 6300AGN)
Intel WiFi Link 1000BGN
Intel Wireless WiFi 5150AGN
Intel Wireless WiFi 5100AGN, 5300AGN, and 5350AGN
Intel 6005 Series Wi-Fi Adapters
Intel 6030 Series Wi-Fi Adapters
Intel Wireless WiFi Link 6150BGN 2 Adapter
Intel 100 Series Wi-Fi Adapters (100BGN and 130BGN)
Intel 2000 Series Wi-Fi Adapters
Intel 7260 Wi-Fi Adapter
Intel 3160 Wi-Fi Adapter
Intel 7265 Wi-Fi Adapter
Intel 8260 Wi-Fi Adapter
Intel 3165 Wi-Fi Adapter


 This driver uses the kernel's mac80211 subsystem.

 In order to use this driver, you will need a firmware
 image for it.

Also, see this Gentoo wiki article for instructions on how to set up
your driver:

Hello,

you could test if iwlwifi was included by running "modprobe iwlwifi" ( as root 
). If it is included but wifi still doesn't work you might have to install the 
relevant firmware ( via emerge linux-firmware )

Regards,
Rasmus

[gentoo-user] genkernel iwlwifi WiFi driver

[Radoje Stojisic]

Hello everyone,

I've installed Gentoo on my ThinkPad T460p couple of times. For some 
reason I can't get the WiFi working. I did the installation with 
SystemRescueCD because I needed working WiFi for the install.


So here comes the question:

I've installed the Genkernel. Does Genkernel enables the iwlwifi driver 
automatically? Or do I need the modify the kernel on my own? I've 
installed Gentoo with KDE. iwconfig showed no wifi interface.



Thanks for any advice.

Greetings
