I recently received a custom-built PC with an ASUS PRIME A520M-A II motherboard and an AWD-IT 5400Mbps Wi‑Fi 6 PCIe wireless/Bluetooth card. Windows installed successfully and the PC works over Ethernet, but no Wi‑Fi networks or Wi‑Fi option appear in Network settings. Device Manager shows Bluetooth under Network adapters, while "Network controller" appears under Other devices with a yellow warning icon. I've installed Windows updates and the motherboard drivers, but the wireless card still isn't detected. The hardware ID is PCIVEN_14C3&DEV_7922&SUBSYS_380411AD&REV_00, which seems to identify a MediaTek device. What driver or setup step am I missing?

The quickest solution may be to contact the company that built the PC and ask for the wireless-card driver or the exact make and model. It sounds like Windows was installed without the PCIe Wi‑Fi driver. You can download the driver on another computer or an Android phone, copy it over with a USB drive or cable, and run the installer on the new PC.
The motherboard itself doesn’t include Wi‑Fi, so its drivers won’t make the wireless card appear. The separate PCIe card needs its own driver, and the listing name may only identify the retailer rather than the actual card manufacturer. The hardware ID you found points to a MediaTek wireless chipset, so try locating the matching MediaTek Wi‑Fi driver or ask the system builder for the exact card model. Since Bluetooth is already working, the card is at least being detected partially.
That makes sense. The hardware ID showing MediaTek is the only identifying information I’ve found so far, so I’ll use that when looking for the correct driver and include it in my support request.
Installing every motherboard driver won’t necessarily install the wireless driver because this is an add-in card. Use the hardware ID to match the MediaTek chipset, or open the case and read the label on the card. Once the Wi‑Fi driver is installed, the warning under Other devices should disappear and the wireless adapter should move into Network adapters.
You can also check the BIOS/UEFI to make sure onboard devices and PCIe settings haven’t been disabled, although that’s less likely with a separate card. Restart the PC, press Delete during startup to enter the firmware settings, and look for device or PCIe options. A BIOS update may help in some cases, but identify the exact Wi‑Fi card and install its driver first rather than updating firmware unnecessarily.
I’ve contacted them, but support is closed for the weekend. I’ll try transferring the correct driver from another device while I wait for their response.
