I think this is because Pi 400 uses different WiFi chip from Pi 4 series. Pi 4 uses brcmfmac43455 but Pi 400 uses brcmfmac43456. Unfortunately, firmware for 43456 is not included in linux-firmware package even now Apr 2023. $ cd /lib/firmware/brcm; ls |grep -i raspberry brcmfmac43430-sdio.raspberrypi,3-model-b.txt.xz brcmfmac43430-sdio.raspberrypi,model-zero-w.txt.xz brcmfmac43455-sdio.Raspberry Pi Foundation-Raspberry Pi 4 Model B.txt.xz brcmfmac43455-sdio.Raspberry Pi Foundation-Raspberry Pi Compute Module 4.txt.xz brcmfmac43455-sdio.raspberrypi,3-model-a-plus.txt.xz brcmfmac43455-sdio.raspberrypi,3-model-b-plus.txt.xz brcmfmac43455-sdio.raspberrypi,4-model-b.txt.xz |

Putting proper firmware in /lib/firmware/brcm will enable Wi-Fi. See this: https://github.com/AlmaLinux/raspberry-pi/issues/23 |
