For Intel wifi there is a separate wiki article.
If problems persist after working through that article, please get your output of lspci -nnkv as mentioned before by mrbassie and pastebin your output of dmesg | grep as from the wiki article.

RIA77,

You only get to configure your kernel settings if you ask to.

Use
Code:
eselect kernel ...
to set the /usr/src/linux symbolic link to the kernel you want to work with.
Do
Code:
cd /usr/src/linux
make menuconfig
to change to your selected kernel and open its configuration tool.
The build sequence in covered in one of the wiki links above.

Follow the iwlwifi wiki page to know what to change.

The kernel has a search facility. Press /
It also hides things that are not selectable. This helps you when you know what you want and what it depends on but it also hides things from the search.
Press z to see even non selectable items. Press z again to hide them.
While hidden items are shown, they can be searched. When you find yon seed a hidden item, look at he depends on.

For example.
Code:
  │ Symbol: IWLWIFI [=n]                                                                                                                       │ 
  │ Type  : tristate                                                                                                                           │ 
  │ Prompt: Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlwifi)                                                      │ 
  │   Location:                                                                                                                                │ 
  │     -> Device Drivers                                                                                                                      │ 
  │       -> Network device support (NETDEVICES [=y])                                                                                          │ 
  │         -> Wireless LAN (WLAN [=y])                                                                                                        │ 
  │ (1)       -> Intel devices (WLAN_VENDOR_INTEL [=y])                                                                                        │ 
  │   Defined at drivers/net/wireless/intel/iwlwifi/Kconfig:1                                                                                  │ 
  │   Depends on: NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_INTEL [=y] && PCI [=y] && MAC80211 [=y] && HAS_IOMEM [=y]                        │ 
  │   Selects: FW_LOADER [=y] 


The Location: tells where in the menu IWLWIFI is
The Prompt: tells mhat to look for in the menu.
Depends on: is a boolean expression that must evaluate to true, or the option will probably be hidden.

Now, there are other Intel WiFI drivers beside iwlwifi and we don't know which driver you need yet.
The idea is the same but you may need a different driver for your wifi.
Your lspci output will tell.

Better use http://sysresccd.org instead as mentioned in https://wiki.gentoo.org/wiki/Wifi#Wifi_during_installation. It's also based on Gentoo.
