ASUS PRIME X570-P: missing LAN, audio and Wi-Fi explained

Match the board before choosing downloads

Open the PRIME X570-P support page, not PRIME X570-PRO or another X570 model. Select your Windows version and check the supported systems stated for each package.

The chipset name describes the platform, not every device attached to it. An AMD chipset package does not replace the Realtek network or audio driver, and a graphics driver does not repair a missing Ethernet controller.

Keep the complete package name and version when downloading. That gives you a useful record if a later update changes the behaviour.

If Ethernet is missing after installing Windows

Use the board's LAN category for the RTL8111H controller. On a PC without internet, transfer the downloaded package from another computer using a USB drive, extract it and follow the installer instructions. Restart when requested.

Then inspect Device Manager. If the network adapter appears normally but Windows reports a disconnected cable, test the cable and router or switch port before repeating the driver installation. If an unidentified device remains, record its Hardware Ids from Properties > Details and the Device status message.

The motherboard firmware also has a Realtek LAN Controller option documented under Advanced > Onboard Devices Configuration. Check whether it is disabled if the controller is absent. Avoid changing unrelated boot, storage or PCIe settings while investigating networking.

If speakers or headphones have no sound

Use the ASUS Audio package for the onboard Realtek device. After installation, check Windows output selection. A display connected by HDMI or DisplayPort can expose a separate playback device; selecting that output will not send sound to the motherboard's analogue speaker jack.

Compare rear output with the case's front headphone jack. If rear output works, the remaining issue may involve the front-panel cable, connector or output configuration. The manual identifies the motherboard's front audio header as AAFP. Shut down and disconnect mains before checking a case cable against its pinout.

A speaker plugged into a monitor, a USB headset and the board's analogue audio are different signal paths. Use the driver and settings for the path you actually want.

Why there is no PRIME X570-P Wi-Fi driver

The documented onboard networking is wired Ethernet. A USB or PCIe Wi-Fi adapter added to this PC needs the package for that adapter's manufacturer and model.

Downloading wireless software from another ASUS motherboard cannot add a radio to the PRIME X570-P. If you already have an add-on adapter, identify it in Device Manager or from its label before selecting a driver.

Once the required devices work, keep optional utilities separate from essential drivers. Install only what serves your setup, and check one change at a time.
