TP-Link Archer T4E AC1200 Wireless Dual Band PCI Express Adapter

Description

The TP-Link Archer T4E AC1200 Wireless Dual Band PCI Express Adapter is a high-performance Wi-Fi 5 (802.11ac) adapter designed to provide fast and reliable wireless connectivity for desktop PCs via a PCI Express x1 interface, compatible with x1, x2, x8, or x16 slots. It supports dual-band Wi-Fi, delivering up to 867Mbps on the 5GHz band for 4K/HD streaming, online gaming, and large file downloads, and 300Mbps on the 2.4GHz band for browsing, emailing, and social media. The 2×2 MIMO technology enhances throughput, while Beamforming focuses Wi-Fi signals toward connected devices for stable connections and boosted range. The dual 2dBi detachable omni-directional antennas (RP-SMA connectors) improve coverage compared to internal antenna models, with the option to upgrade to higher-gain antennas.

The plug-and-play functionality ensures driver-free setup for Windows 11/10/8.1, while Windows 8/7/XP (32/64-bit) require drivers from TP-Link’s website (https://www.tp-link.com/support/download/archer-t4e/). It supports WEP, WPA/WPA2, WPA-PSK/WPA2-PSK, 802.1x encryption for secure connections. An aluminum-alloy heat sink dissipates thermal energy, improving stability and extending lifespan. Measuring 120.8 × 115.2 × 21.5 mm and weighing ~80g, it includes a low-profile bracket for mini-tower cases. Reviews praise its easy installation, reliable speeds, and strong signal, though some users report occasional driver issues on older systems and weaker 2.4GHz performance in crowded environments. The Resource CD and Quick Installation Guide simplify setup.

Compared to the TL-WN881ND (300Mbps, 2.4GHz-only), the T4E offers dual-band and faster 5GHz speeds. Unlike the Archer T5E (AC1200, Wi-Fi 5 + Bluetooth), it lacks Bluetooth. Compared to the Archer TX20U Plus (AX1800, Wi-Fi 6), it’s limited to Wi-Fi 5. Unlike the UH7020C (7-in-1 hub), it focuses solely on Wi-Fi connectivity. It’s ideal for users upgrading desktops for high-speed, dual-band Wi-Fi.
