Hi.

I have a router that has 2 channels of WiFi, one 2.5GHz and the other is 5GHz.
If i connect to the 5GHz network, the connection is fast but very unstable.
for example speedtest.net sometimes isn't connecting at all and Youtube runs at the lowest quality with automatic settings turned on...

The 2.5GHz connection works and is very stable. I can have 150Mbps
 at speedtest.

This is the WiFi controller i have:
00:14.3 Network controller: Intel Corporation Cannon Lake PCH CNVi WiFi (rev 10)

journalctl isn't giving me any errors, also dmesg gives nothing.

$ uname -a
Linux gentoo 5.15.69-gentoo-dist #1 SMP Tue Sep 20 14:40:36 -00 2022 x86_64 Intel(R) Core(TM) i5-9300H CPU @ 2.40GHz GenuineIntel GNU/Linux

So i am running sys-kernel/gentoo-kernel-bin
