Read the expansion card's documentation to check for any necessary additional hardware or software changes. ∙∙The PCIe x1 slot and onboard Wi-Fi module share the same bandwidth, you can not use both of them simultaneously, and the default setting is the Wi-Fi module for the system. Please disable the Onboard Wi-Fi Module Control in BIOS if you want to use the PCIe x1 slot.
