Dear Friends,

I need help. My gentoo's connection for 5g wifi failed, but 2.4g wifi work fine as before. Even the 5g AP can be found.

Code:
[   79.891187] wlp4s0: authenticate with b0:6e:bf:62:da:ec
[   79.898557] wlp4s0: send auth to b0:6e:bf:62:da:ec (try 1/3)
[   79.900136] wlp4s0: authenticated
[   80.512694] iwlwifi 0000:04:00.0: No beacon heard and the time event is over already...
[   80.512745] wlp4s0: Connection to AP b0:6e:bf:62:da:ec lost
[   84.002197] wlp4s0: aborting authentication with b0:6e:bf:62:da:ec by local choice (Reason: 3=DEAUTH_LEAVING)

[   91.569935] wlp4s0: authenticated
[   91.580135] wlp4s0: associate with b0:6e:bf:62:da:e8 (try 1/3)
[   91.583864] wlp4s0: RX AssocResp from b0:6e:bf:62:da:e8 (capab=0x411 status=0 aid=3)
[   91.589830] wlp4s0: associated
[   91.616519] IPv6: ADDRCONF(NETDEV_CHANGE): wlp4s0: link becomes ready


I can't understand at all.

Do you have "sys-kernel/linux-firmware" package installed? Could be missing firmware.

With missing firmware the device wouldn't show up to userspace at all though?

It might be a misconfigured region on the AP or client. Make sure crda is installed and the regulatory.db{,.p7s} files from linux-firmware are compiled in too, if the wifi driver is.
