AC1200M PCI-E Wireless Adapter

The IHDAPP AC1200M is a PCI Express network card that adds dual-band Wi-Fi to a desktop computer. It connects through any standard PCIe slot from x1 to x16 and ships with two detachable 5 dBi antennas for adjustable positioning. The card supports IEEE 802.11 a/b/g/n/ac standards and delivers a maximum link rate of 1200 Mbps across the 2.4 GHz and 5.8 GHz bands.

Desktop builders needing internal Wi-Fi without USB

This adapter suits Windows 10, 8.1, 8 and 7 systems that have a free PCIe slot and want an internal solution with external antennas. It includes both low-profile and full-height brackets for slim or standard chassis. Buyers who need Bluetooth connectivity, a USB interface, or operating-system support beyond the listed Windows versions should look elsewhere.

1200 Mbps dual-band throughput rating

The single figure that determines suitability is the 1200 Mbps maximum wireless data rate split between the 2.4 GHz and 5.8 GHz frequencies. If your network plan or usage demands higher throughput, this card will not meet that requirement.

Questions about this item

Does the card fit a standard PCI Express x1 slot?

Yes, it works in any standard PCIe x1, x4, x8 or x16 slot on a desktop motherboard.

What is the trickiest part of installing the driver from the included CD?

Run the setup utility before inserting the card, then shut down, install the hardware, and reboot so Windows 10/8.1/8/7 detects it correctly.

When should the external 5 dBi antennas be replaced?

Replace them if the connectors loosen, the gain drops noticeably, or physical damage affects 2.4 GHz and 5.8 GHz signal quality.
