(iwlwifi) Randomly stops connecting to 5Ghz networks

This usually happens after i reboot my laptop. I try to connect to my 5.18 GHz network and get error:

[   13.511539] wlan0: authenticate with e4:7d:eb:e1:92:9b

I can still connect to 2.432 GHz wifi. And after some time this issue disappears and everything comes back to working fine.

At first a fix with disabling power management worked, but now it doesn't, so perhaps that wasn't a fix but a coincidence. I made sure that it actually is disabled:

❯ iwlist wlan0 power
wlan0     Current mode:off

❯ iwlist wlan0 frequency
wlan0     32 channels in total; available frequencies :
          ...
          Channel 36 : 5.18 GHz
          ...
          Current Frequency:5.18 GHz (Channel 36)

Edit, some extra information
- I can connect/reconnect to the same 5 GHz wifi from my phone, so I don't believe it is a router issue.
- If it's important, my hardware:

00:14.3 Network controller: Intel Corporation Comet Lake PCH CNVi WiFi
    Subsystem: Intel Corporation Wi-Fi 6 AX201 160MHz
    Kernel driver in use: iwlwifi
    Kernel modules: iwlwifi

❯ uname -r
6.4.3-arch1-1

My laptop model is Nitro AN515-55 V2.06
