TP-Link Archer TBE400U Plus Wi-Fi 7 USB Network Adapter
Bring Wi-Fi 7 to Any Desktop or Laptop
The TP-Link Archer TBE400U Plus is a high-gain tri-band Wi-Fi 7 USB adapter that upgrades any desktop or laptop to the latest wireless standard — no PCIe slot required. With support for the 6 GHz band and Multi-Link Operation (MLO), it delivers faster speeds, lower latency, and a more stable connection than any previous Wi-Fi generation.
Description
Designed for users who want to future-proof their existing PC or workstation, the Archer TBE400U Plus connects via USB 3.0 and supports the full tri-band BE3600 specification: 2.4 GHz, 5 GHz, and the newly available 6 GHz band. The included high-gain antenna base provides a stronger, more directional signal compared to compact dongle-style adapters, making it well suited to larger rooms or environments with significant wireless interference.
Driver installation is straightforward on both Windows and macOS, and the adapter is backward compatible with Wi-Fi 6, 5, and earlier routers and access points.

Frequently Asked Questions
- Do I need a Wi-Fi 7 router to use the Archer TBE400U Plus?
- No. The adapter is backward compatible with Wi-Fi 6, 5, and 4 routers. However, Wi-Fi 7 speeds and features such as MLO are only available when connected to a Wi-Fi 7 access point or router.
- Does the Archer TBE400U Plus work on macOS?
- Yes. The adapter supports macOS 10.15 (Catalina) and later. Driver installation is required and available from the TP-Link AU support page.
- Can I use this adapter with a USB 2.0 port?
- The adapter uses a USB 3.0 interface for maximum throughput. It may function in a USB 2.0 port, but speeds will be limited by the USB 2.0 bandwidth ceiling of 480 Mbps. A USB 3.0 port is strongly recommended.
- What is the advantage of the 6 GHz band?
- The 6 GHz band is less congested than 2.4 GHz and 5 GHz, offering lower latency and higher throughput in environments with many wireless devices. It requires a Wi-Fi 6E or Wi-Fi 7 router to access.
- Is the antenna detachable or fixed?
- The Archer TBE400U Plus features a high-gain antenna on an adjustable base connected via USB cable, allowing flexible positioning for optimal signal reception.
