Research direction
Reproduce the issue using the listed Raspberry Pi 3B+, Raspbian release, kernel version, and NL regulatory domain through raspi-config or wpa_supplicant.conf. Compare the 5 GHz connection behavior with the US domain, then trace the kernel wireless regulatory handling; done means the NL configuration permits the expected 80 MHz connection.

Description
Describe the bug
The Raspberry Pi is unable to sync with 80mhz channels to my AC WiFi access point when I set my regulatory domain to NL. It is able to do so whenever I utilize the US domain. The NL domain does and should support 80mhz channels. More people seem to experience this issue as is evident here: https://www.raspberrypi.org/forums/viewtopic.php?t=208384
To reproduce
- Fresh boot of Raspbian
- Set the regulatory domain to NL via raspi-config or wpa_supplicant.conf
- Connect to 5 Ghz WiFi
Expected behaviour
Connects with 80mhz channel at 433 Mbit physical link speed
Actual behaviour
Connects with 40mhz channel at 200 Mbit physical link speed
