Without knowing what problem you're experiencing and what you've done, it is difficult to help.

I'd recommend starting with the WiFi guide. If you aren't certain of the driver you need, it will likely be best to boot from a LiveCD or similar bootable image. Details are in the guide in the section "Hardware detection".

The biggest problem is that i can't see wlan device with if config. I think i've not installed the right module when i compiled the kernel. If i should recompile the kernel, what i have to do? Thanks!

I searched the Gentoo Wiki for the "3168NGW" string, and I found this.

Basically you need to rebuild the kernel and enable the CONFIG_IWLWIFI option. It's called Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlwifi) and you can find it under Device Drivers > Network device support > Wireless LAN.

You also need to install the (proprietary) firmware.

For more details, see this Gentoo wiki article.

Oh, perfect, i will try that way. Just another question: to rebuild the kernel, can i follow what "Muso" said in https://forums.gentoo.org/viewtopic-t-1091116-start-0.html? And i don't need to boot from installer usb?

Muso's procedure seems fine to me. You don't need to use a USB installer as long as you can successfully boot your Gentoo system from the HDD/SSD.

Edit: replace "make -j4" with "make -jn", where "n" is the number of CPU cores on your system. If you have a quad-core CPU, then "make -j4" is fine.
