Product Description

The TP-Link Archer T4E AC1200 Wireless Dual Band PCI Express Adapter is a high-performance internal Wi-Fi 5 (802.11ac) network card designed to upgrade desktop computers with fast and stable wireless connectivity. It connects directly to a PCIe slot, providing a more reliable and stronger connection than USB Wi-Fi adapters.

It supports dual-band operation, offering speeds up to 867Mbps on the 5GHz band and 300Mbps on the 2.4GHz band. This allows users to enjoy high-speed performance for gaming, HD/4K streaming, and large downloads on 5GHz, while maintaining stable long-range connectivity on 2.4GHz.

The adapter comes with two high-gain external antennas that improve signal strength and coverage. It also supports Beamforming technology, which focuses Wi-Fi signals toward connected devices for better stability and range. With 2×2 MIMO support, it ensures improved data transmission efficiency in multi-device environments.

Additional features include a built-in heat sink for better thermal stability and low-profile brackets for flexible installation in different PC cases.
