ha17h3m,

Welcome to Gentoo.

A few things. It appears that your wireless interface is not present.
It may mean that the kernel module is not compiled or loaded, or both. Likewise with the firmware.

Please post the output of lspci so that we can see your hardware, in particular, your Wifi.

Use wgetpaste to put your kernel .config file onto a pastebin site, so we can see your kernel setup.
Post the link it gives you here.

The output of the dmesg command will also be useful. That will need to go to a pastebin.
wgetpaste can help there too.

ha17h3m,

Yes. Once in the chroot, do
Code:
emerge pciutils usbutils wgetpaste -av


pciutils provides lspci.
usbutils provides lsusb - which you may not need right now.
wgetpaste provides wgetpaste.

We really want to see dmesg from your kernel, not a working one.
Boot your own kernel and run
Code:
dmesg > /root/dmesg.txt
This will save dmesg to the file /root/dmesg.txt.

Reboot with your live media. Get into the chroot, do the emerge above then run
Code:
lspci | wgetpaste
wgetpaste /root/dmesg.txt
wgetpaste /usr/src/linux/.config


and make a post with the three links that wgetpaste returns.

Actually, the dmesg may be there already, /mnt/gentoo/var/log/dmesg.

This dmesg is not from your kernel.

Something is off here, you stated the interface does not exist, but it's in the dmesg.

This kernel has timestamp #1 SMP Sun Jan 6 13:57:07 MSK 2019

You sure this is the latest kernel you built?

ha17h3m,

Your WiFi is
lspci:
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)


Google tells me that neds the iwlwifi driver.
.config:

CONFIG_WLAN_VENDOR_INTEL=y
# CONFIG_IPW2100 is not set
# CONFIG_IPW2200 is not set
# CONFIG_IWL4965 is not set
# CONFIG_IWL3945 is not set
CONFIG_IWLWIFI=m
CONFIG_IWLWIFI_LEDS=y
CONFIG_IWLDVM=m
CONFIG_IWLMVM=m
CONFIG_IWLWIFI_OPMODE_MODULAR=y
# CONFIG_IWLWIFI_BCAST_FILTERING is not set

#
# Debugging Options
#
# CONFIG_IWLWIFI_DEBUG is not set
CONFIG_IWLWIFI_DEVICE_TRACING=y
so far, so good.

dmsg:
[    0.000000] Linux version 4.14.83-gentoo (root@livecd) (gcc version 7.3.0 (Gentoo 7.3.0-r3 p1.4)) #1 SMP Sun Jan 6 13:57:07 MSK 2019

That says your running kernel was made at Sun Jan 6 13:57:07 MSK 2019.
The #1 means its the first build of that kernel too.

Lets check for consistency.
The timestamp or /usr/src/linux/.config munt be before Sun Jan 6 13:57:07, or the dmesg you are showing us cannot belong to the .config you posted.
What does
Code:
ls -l /usr/src/linux/.config
show?

dmesg makes no mention of iwlwifi, which suggests that you have changed the kernel .config without rebuilding and reinstalling the kernel.
What does
Code:
modprobe  iwlwifi
tell?
If there is an error, there may be more at the end oy dmesg.
If there is no error, what does
Code:
ifconfig -a
show now?

ha17h3m,

Don't start again. That will not fix Gentoo.

Code:
# mobprobe iwlwifi
mobprobe: FATAL: Module iwlwifi not found in directory /lib/modules/4.14.83-gentoo


Tells that the kernel you are running was not made for the .config file that your posted.
You need to remake the kernel, that's all. Not redo the whole install.

Maybe even remake is not needed, just install properly? There is that dreaded 'noauto' mount option in the fstab ...
