TP-Link Archer TX35U Plus WiFi 6 USB Adapter Review (2026): Add AX1800 WiFi 6 to Any Desktop

What Is the TP-Link Archer TX35U Plus?

The TP-Link Archer TX35U Plus is a WiFi 6 (802.11ax) USB 3.0 wireless adapter designed to add modern wireless connectivity to desktop PCs, mini PCs and other devices without a WiFi slot. It plugs into a standard USB 3.0 port and provides dual-band AX1800 wireless — up to 1201Mbps on 5GHz and 574Mbps on 2.4GHz — bringing WiFi 6 performance to older machines that only have Ethernet or an older WiFi card.

Released in 2025, the TX35U Plus is the upgraded version of TP-Link's popular TX35U, adding higher-gain antennas for better range and signal penetration through walls.

Why Upgrade to WiFi 6?

WiFi 6 (802.11ax) introduces several meaningful improvements over WiFi 5 (802.11ac): OFDMA allows the router to serve multiple devices simultaneously in the same channel (reducing congestion in busy office or home networks), MU-MIMO allows multiple simultaneous streams, and TWT (Target Wake Time) reduces battery drain on connected devices. In real-world terms, WiFi 6 is faster, more stable under load, and more efficient — particularly noticeable when many devices are connected to the same network.

If your router already supports WiFi 6 (like the Ruijie Reyee RG-RAP62 reviewed separately), adding a WiFi 6 adapter to your desktop unlocks the full performance of your network.

Key Features

AX1800 Dual-Band — Up to 1201Mbps on 5GHz

The TX35U Plus achieves a combined maximum of 1800Mbps: 1201Mbps on the 5GHz band (for fast, low-latency connections to nearby routers) and 574Mbps on 2.4GHz (for longer range with better wall penetration). In practice, real-world speeds on 5GHz in a typical office environment reach 400–700Mbps — a massive improvement over WiFi 5 adapters or no WiFi at all.

High-Gain External Antennas — Better Range Through Walls

The dual external antennas are the key upgrade over the standard TX35U. Higher-gain antennas capture WiFi signals more efficiently from greater distances and through building materials, reducing dropouts and improving stability in rooms where the router is not in direct line of sight. The antennas are adjustable, allowing you to orient them for optimal signal reception based on where your router is positioned.

USB 3.0 — Full Speed Data Transfer

The USB 3.0 interface ensures the adapter does not become a bottleneck for data transfer. At up to 5Gbps theoretical throughput, USB 3.0 comfortably handles the maximum wireless speeds of AX1800, unlike USB 2.0 which would limit performance to ~480Mbps. Connect to a USB 3.0 port (blue port) on your PC for best results — USB 2.0 ports will work but may cap speeds.

MU-MIMO — Simultaneous Multi-Device Efficiency

MU-MIMO (Multi-User, Multiple Input Multiple Output) allows the adapter to communicate with the router in a more efficient, parallel fashion. In networks with multiple active devices, this reduces waiting time and maintains more consistent speeds compared to single-user MIMO adapters.

WPA3 Encryption — Modern Security Standard

WPA3 is the current WiFi security standard, offering stronger protection than WPA2 against offline dictionary attacks. If your router supports WPA3 (most WiFi 6 routers do), using a WPA3-capable adapter like the TX35U Plus ensures your connection uses the strongest available encryption.

Technical Specifications

Who Is It Best For?

• Desktop PC owners who want to add WiFi 6 without opening the case or installing a PCIe card
• Mini PC users (Dell OptiPlex, Intel NUC, etc.) that lack onboard WiFi or have older WiFi 5
• Home office workers with a WiFi 6 router who want to match performance on their desktop
• Network administrators adding wireless capability to wired-only workstations temporarily
• Anyone upgrading from a slow, unreliable WiFi 4 or WiFi 5 USB adapter

Pros & Cons

Installation Tips

• Use a USB extension cable to position the adapter away from the PC case if the rear ports block the antenna signal. A 30cm USB extension cable makes a significant difference in signal strength.
• Install the latest driver from TP-Link's website rather than using Windows Update — the manufacturer driver is more stable and includes configuration software.
• Connect to a USB 3.0 port (blue port) for maximum throughput. Avoid USB 2.0 ports on very fast networks.

Our Verdict

The TP-Link Archer TX35U Plus is the simplest, most accessible way to add WiFi 6 performance to a desktop PC. The high-gain antennas, USB 3.0 interface, MU-MIMO, WPA3 and AX1800 speeds cover everything a modern home or office network demands. For anyone with a WiFi 6 router who is still connecting their desktop via WiFi 5 or a slow USB dongle, the TX35U Plus is an easy, cost-effective upgrade.
