This article covers ASUS 4K モニター ProArt PA329CRV 31.5インチ.

Overview

The TP-Link Archer T3U Plus is a compact USB Wi-Fi adapter that brings wireless connectivity to desktop PCs and laptops without built-in Wi-Fi. It supports Wi-Fi 5 (802.11ac) with a combined data rate of up to 1300 Mbps (867 Mbps on 5 GHz + 400 Mbps on 2.4 GHz), making it a solid choice for everyday browsing, streaming, and light online gaming. What sets this adapter apart from basic USB dongles is the included magnetic stand base. You can attach the base to a metal surface or simply place it on your desk, then connect the adapter via the bundled USB extension cable. This lets you position the antenna for better signal reception, which is a real advantage in rooms where the PC sits under a desk or in a corner.

Connectivity & Compatibility

The Archer T3U Plus uses a USB 3.0 interface (backward compatible with USB 2.0/1.1). It supports Windows 10/11 and select Linux distributions out of the box; macOS is not officially supported. Security protocols include WPA2, WPA3, and WEP. The adapter also supports MU-MIMO, which helps maintain stable throughput when multiple devices are connected to the same router.

Product Info

Released in late 2021, the Archer T3U Plus sits in the entry-to-mid tier of TP-Link's USB adapter lineup. Its street price is around ¥2,000 (≈$15–20). The package includes the adapter unit, a magnetic stand base, a USB extension cable (roughly 1 m), and a quick-install guide. TP-Link offers a standard 2-year warranty for the Japanese market.

Best Use Cases

Desktop PC owners without built-in Wi-Fi — If your motherboard lacks Wi-Fi, this adapter is the cheapest way to add it without opening the case. Renters or users in hard-to-wire rooms — The magnetic stand and USB extension let you place the antenna in an optimal spot, improving signal strength. * Budget-conscious shoppers — At under ¥2,500, you get AC1300-class performance that easily handles 4K streaming and video calls. If you already own a Wi-Fi 6 (802.11ax) router, consider stepping up to the Archer T4U or T9U for higher real-world throughput. Also, macOS users should look elsewhere — this adapter is not officially supported on Apple Silicon. ## Alternatives
Direct competitors include the Buffalo AirStation WLI-UC-AC866 (similar AC866 speed, USB 3.0) and the ASUS USB-AC56 (AC1300, USB 3.0). The Archer T3U Plus stands out with its magnetic stand and extension cable, offering better placement flexibility. Buffalo's driver stability is generally better on Windows, while ASUS's model has a slightly larger body but good built-in antenna performance.

Things to Consider

macOS is not officially supported — avoid this if you use a Mac with Apple Silicon. For best performance, plug it into a USB 3.0 port; USB 2.0 will cap the adapter's speed. * The 867 Mbps on 5 GHz is a theoretical maximum; real-world speeds depend on router distance, walls, and interference.
