Certain wireless networks are not being detected on my gentoo install, but are being detected from a LMDE 5 live USB on the same hardware.
My phone can also detect it

Apparently, same firmware and drivers on both:

ON LMDE5 LIVE USB:
Code:

# lsmod | grep iwl
iwlmvm                339968  0
mac80211              983040  1 iwlmvm
iwlwifi               294912  1 iwlmvm
cfg80211              970752  3 iwlmvm,iwlwifi,mac80211


Code:

Network is detected and connected normally:

ON GENTOO INSTALL:
dmesg, modules and ip a are almost identical, nothing out of the ordinary:
Code:

The network is no longer detected:

# nmcli device wifi list

        08:40:F3:13:68:F1  Wi-Fi João           Infra  3     130 Mbit/s  15      ▂___  WPA1 WPA2


I suspect I might have misconfigured my kernel, though it wasn't detected when I was using genkernel either. Haven't tried with dist-kernel.
My kernel .config: https://pastebin.com/vjS5YTzj

Recently, net-wireless/wpa_supplicant disabled the tkip USE by default which wpa_supplicant will not show WPA nor mixed mode WPA/WPA2.

The choices are, if possible, disable WPA (in favor of just WPA2) on any routers you can configure, or failing to have access, enable the tkip USE on net-wireless/wpa_supplicant

This worked, thank you.
Didn't think about it being due to a USE flag.
For whatever reason I was fixated on it being a firmware issue.
