pi4 2.4GHz yes 5GHz no

[jal]

Title sums it up. I can see the 5GHz SSID, but only connect to the 2.4GHz SSID.
The pi3a running debian buster connects to the 5GHz fine.

networkmanager 1.24.0-1
pacman -Ss linux | grep pi4
core/linux-raspberrypi4 5.4.35-1 [installed]
core/linux-raspberrypi4-headers 5.4.35-1 [installed]

Any tips?

Cheers
