TP-LINK Archer TBE400E (UN) — BE6500 Wi-Fi 7 + Bluetooth PCIe Adapter

Upgrade your desktop PC to next-gen Wi-Fi 7 (802.11be) and Bluetooth 5.4. Archer TBE400E is a tri-band PCI Express adapter designed for ultra-high throughput, lower latency, and better performance in busy homes and offices. It includes high-gain external antennas, WPA3 security, and brackets for standard or low-profile PC cases.

Highlights

• Tri-Band Wi-Fi 7 (2.4 / 5 / 6 GHz) for flexible, high-speed connectivity
• BE6500 class speeds (theoretical): up to ~2882 Mbps (6 GHz) + ~2882 Mbps (5 GHz) + ~688 Mbps (2.4 GHz)
• MLO (Multi-Link Operation) to intelligently use multiple bands for higher throughput and lower latency
• 4K-QAM, OFDMA, MU-MIMO for improved spectral efficiency and multi-device performance
• Bluetooth 5.4 for headsets, controllers, keyboards, mice, and more (via included motherboard USB header cable)
• WPA3 wireless security, with backward compatibility to WPA2/WPA
• 2× high-performance external antennas for stronger reception and wider coverage
• Full-height & low-profile brackets included for wide case compatibility
• Designed for Windows 11 (64-bit) with easy driver installation

Who Is It For?

Ideal for gamers, creators, and power users who want cutting-edge wireless performance on a desktop PC—especially if you already have (or plan to get) a Wi-Fi 7 router to unlock features like 320 MHz channels, MLO, and 4K-QAM.

Speed & Bands (Theoretical Maximums)

Key Technologies

• MLO (Multi-Link Operation): Uses multiple bands simultaneously for higher throughput and resiliency.
• 4K-QAM: Packs more data per symbol for higher peak speeds in good signal conditions.
• OFDMA & MU-MIMO: More efficient airtime sharing when many devices are active.
• Target Wake Time (TWT): Helps reduce airtime contention and improve efficiency (router support required).
• WPA3: Next-gen Wi-Fi security for better protection of your network traffic.

Detailed Specifications

Package Contents

• Archer TBE400E Wi-Fi 7 + Bluetooth PCIe adapter
• 2 × external high-gain antennas
• Low-profile bracket (in addition to pre-installed full-height bracket)
• Bluetooth (USB) header cable (~30 cm)
• Quick Installation Guide / documentation

Installation Notes

1. Power off the PC and insert the adapter into an available PCIe slot.
2. Install either the full-height or low-profile bracket to match your case.
3. Connect the included Bluetooth cable from the adapter to a free USB 2.0 motherboard header (F_USB).
4. Attach the two external antennas and orient them for best signal.
5. Boot into Windows 11 (64-bit) and install the latest TP-LINK drivers/utility.

Compatibility & Requirements

• Desktop PC with one free PCIe slot (x1 or larger)
• Windows 11 (64-bit)
• Bluetooth functionality requires the included internal USB header cable to be connected
• Full Wi-Fi 7 features (e.g., MLO, 320 MHz, 4K-QAM) require a compatible Wi-Fi 7 router/AP
• 6 GHz band availability is region-dependent and may be restricted

Important Notes & Disclaimers

• Listed speeds are theoretical PHY rates; real-world throughput will be lower and depends on environment, router capabilities, interference, and client configuration.
• Feature availability (e.g., certain channel widths or bands) can vary by country/region and regulatory rules.
• Product labeling “(UN)” indicates a universal packaging/region code; exact specs/accessories may vary slightly by market.
