No wifi/wlan after installation (wlp)

So I just finished installing gentoo but I have no wifi connection, when I do ifconfig it doesn't show my wifi (wlp5s0), my Linux mint install does. enp6s0 shows up, that's my LAN, but I don't want to use that.

I installed dhcpcd and the wifi tools as stated by the gentoo handbook.

I am using a tp link wifi card (archer tx50e) and I went to tp link website and the only thing it said was that it uses an intel chipset. So I enabled all intel networking kernel modules and recompiled the kernel. Still no luck.

Can someone help me with this? I don't want to use LAN.

Does it show up if you do ip link instead of ifconfig? I ask because ifconfig only shows active and configured interfaces by default.

Also, how did you configure the wireless to start?

Triliner,

Welcome to Gentoo Forums !

In addition to our developer @grknight I want to give you some hints;

1. If your wlan works when booting Linux Mint then do there a "lspci -k". You will see the kernel module for your wlan. So, you dont need to enable many unused kernel modules.

2. This kernel module will need some firmware. Please read this short chapter:
https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_kernel_configuration#Driver_needs_Firmware

3. So, yes it depends if you have enabled your wlan module static or as <M>odule. Now look into your "dmesg" and check if there are some errors.

If you need more help please give us the output of:

a) emerge --info
b) output of dmesg
c) output of lspci -k
d) your kernel .config

(Please use wgetpaste for b) and d) because it will not fit into a post)

The state of sit0 is also DOWN when checked with ip link, just like enp6s0, my ethernet.

Ok so I ran lspci -k on linux mint and I think I found a kernel module for my wifi
[05:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)
Subsystem: Intel Corporation Wi-Fi 6 AX200NGW
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
]

Here is my dmesg output: https://pastebin.com/ZnK2iLLK (Sorry im not familiar with wgetpaste or how to use it so I used pastebin)

The dmesg output is also from linux mint. I will do the rest on my gentoo

is better you post your dmesg and other request output from gentoo not linux mint

Thanks guys for the help I really appreciate it. After installing the Intel wifi kernel modules that I actually need, wlp5s0 shows up. Currently it's at DOWN state but I'll try working on that.
