This is the ASUS PCE-AC58BT wireless LAN adapter. It connects via PCI Express x1 and uses an Intel AC-9260. It supports Wi-Fi 5 (11ac). It can generally be used as is with the PCI Express x1 connection, but if you're concerned, you can download drivers from the ASUS support page. ⚠️ Only the main unit and the internal USB pin header cable shown in the photos are included. The low-profile bracket, antenna, and original box are not included. Please be aware of this before purchasing.
