AC1200 dual-band PCIe Wi-Fi adapter

The TP-Link Archer T4E adds wireless connectivity to a desktop PC through an available PCI Express slot. It delivers up to 1200 Mbps combined throughput across 2.4 GHz and 5 GHz bands with 2×2 MIMO and beamforming. Two detachable dual-band antennas provide extended range. The card supports Windows 10, 8.1, 8, 7 and XP in 32-bit and 64-bit versions.

Check PCIe slot clearance and OS version

Verify that your motherboard has a free PCI Express slot and enough physical space around it for the card and its antennas. The package includes both a low-profile bracket and a full-height bracket for different chassis sizes. Confirm your operating system matches the supported Windows releases listed in the specifications.

Replaces missing or slower internal Wi-Fi

This adapter upgrades a desktop that lacks built-in Wi-Fi or relies on an older 802.11n card limited to lower throughput. The jump is worthwhile when you need 867 Mbps on the 5 GHz band or 300 Mbps on 2.4 GHz for streaming, gaming or large file transfers. It is not suited for systems without a spare PCIe slot or for non-Windows platforms.

Questions about this item

Does the Archer T4E include antennas and a low-profile bracket, or must they be purchased separately?

The package contains the adapter, two detachable dual-band antennas, a low-profile bracket, a full-height bracket, a quick installation guide and a resource CD.

Should I choose the 5 GHz band for the 867 Mbps rate or the 2.4 GHz band for the 300 Mbps rate?

Use the 5 GHz band when your router supports 802.11ac and you need the higher 867 Mbps link rate; the 2.4 GHz band tops out at 300 Mbps but reaches farther through walls.

What does the 1200 Mbps headline speed mean once the card is installed in a desktop?

It is the combined theoretical maximum of 867 Mbps on 5 GHz plus 300 Mbps on 2.4 GHz; real-world throughput will be lower and depends on router capability, channel width and interference.
