Overview

The FCC test report notes the manuf. as Arcadyan.

The PCI ID for this device is found in the driver set for the ASUS PCE-AC68.

It seems to be using the default BCM4352 ID.

BCM4352_D11AC_ID	0x43b1    /* 4352 802.11ac dualband */
BCM4352_D11AC2G_ID	0x43b2    /* 4352 802.11ac 2.4G device */
BCM4352_D11AC5G_ID	0x43b3    /* 4352 802.11ac 5G device */

On Windows, the chipset Broadcom BCM4352 in the ASUS PCE-AC56 has a driver update, which is missing from the ASUS website and from Windows Update. The driver is called: "broadcom bcm-43xx 7.77.119.0". It was issued in 2020. The update offered by ASUS or Windows Update dates from 2015 or 2017, and is not officially compatible with Windows 10 and 11. The driver update fixes some issues not appearing on Windows 7, but appearing on Windows 10. The update is present in Windows Update (internal code: "VEN_14E4 DEV_43B1") "https://www.catalog.update.microsoft.com/Search.aspx?q=VEN_14E4%20DEV_43B1", but it will not show for the ASUS PCE-AC56. You can download directly your driver update from this website maintained by Microsoft.

The Asus PCE-AC56 is a PCI Express WiFi card with PCI ID: 14e4:43b1

03:00.0 Network controller [0280]: Broadcom Corporation Device [14e4:43b1] (rev 03)

The card uses the Broadcom BCM4352 chipset and wireless connections of 802.11ac standard.

Until now there is no Linux driver for the Asus PCE-AC56 in the Linux standard kernel.

However, a driver for the used chipset is provided by Broadcom for download.

This driver has to be compiled and installed per hand.
