Pre-configure WiFi Before First Boot

No Ethernet and need WiFi working on first boot? You can hardcode credentials from another PC before plugging the USB into your PS5.

# Mount the rootfs partition from the flashed USB
MNT=$(mktemp -d)
sudo mount /dev/sdX1 "$MNT"

# Create the NetworkManager connection file
sudo install -d -m 700 "$MNT/etc/NetworkManager/system-connections"
sudo tee "$MNT/etc/NetworkManager/system-connections/wifi.nmconnection" >/dev/null <<'EOF'
[connection]
id=wifi
type=wifi
autoconnect=true

[wifi]

ssid=YOUR_SSID_HERE

[wifi-security]

psk=YOUR_PASSWORD_HERE

sudo chmod 600 "$MNT/etc/NetworkManager/system-connections/wifi.nmconnection"
sudo chown root:root "$MNT/etc/NetworkManager/system-connections/wifi.nmconnection"
sudo umount "$MNT"

Arch - Install Failing (Missing / Wrong Headers Path)

If ./install.sh fails on Arch, first make sure headers are installed:

sudo pacman -U linux-bin/linux-ps5-headers_*.pkg.tar.zst

Headers are in the same linux-bin/ folder as the kernel package, or download from ps5-linux-patches releases.

If it still fails, there is a known packaging bug where headers get installed to /usr/usr/include instead of /usr/include. Fix:

sudo cp -r /usr/usr/include/* /usr/include/

Confirmed working on CachyOS Arch base.

Known Issues

WiFi may need to be disabled and re-enabled after first boot to get a connection. If it drops under load, reload the driver (this is a known occurance):

sudo modprobe -r moal mlan
sudo modprobe cfg80211
sudo insmod ./mlan.ko
sudo insmod ./moal.ko fw_name=nxp/pcieuartiw620_combo_v1.bin pcie_int_mode=1 drv_mode=1 cfg80211_wext=4 sta_name=mlan ext_scan=1 auto_fw_reload=0 wifi_reset_config=0 sched_scan=0 ps_mode=2 auto_ds=2 amsdu_disable=1
