Expecting restock
Tiny AC1300 class wireless Wi-Fi adapter with USB 3.2 Gen1 interface and support for Wi-Fi 5 over-the-air data transmission standard. It is a full-fledged dual-band client device of 2019, providing significantly higher user data transfer rates than rapidly aging compact single range adapters. The manufacturer is positioning itself as a product of the middle price category, intended for use in laptops, PCs and small-sized HTPC systems. With short distances to a wireless router or access point, it allows you to fully replace a wired network connection of the Fast Ethernet class, refusing to lay a cable. The TP-LINK Archer T3U wireless adapter does not have external antennas and supports MU-MIMO multi-stream data transfer technology. Can create connections with theoretical bandwidths up to 40...0 Mbps (2.4 GHz) and 867 Mbps (5 GHz). The characteristics claimed by the manufacturer guarantee trouble-free surfing, comfortable viewing of 4K-quality streaming video, network gaming, fast downloading of large files from file-sharing networks, smooth operation of web applications and any cloud services.

Model overview based on user reviews  
The TP-LINK Archer T3U Wi-Fi adapter is a compact device designed to enhance internet speed for laptops with weak Wi-Fi receivers or PCs without built-in Wi-Fi. It supports dual-band frequencies, offering theoretical speeds of up to 400 Mbps on 2.4 GHz and 867 Mbps on 5 GHz. However, user reviews indicate some challenges with the 5 GHz band. Users report that the adapter requires specific router settings to function properly at 5 GHz, such as selecting channels from a specific list and limiting bandwidth to 40 MHz. While the adapter can achieve fast speeds under optimal conditions, its performance is described as unstable, and it may not work out of the box without adjustments. Despite its affordable price and compact size, potential buyers should be aware of these limitations and consider the need for technical adjustments to achieve desired performance.
Pros

Cons

[censored], not an adapter
11 January 2022 
I chose this adapter based on its specifications - I needed a fast 5GHz device, and the price was generally acceptable. Before that, I had a Chinese no-name for 300 rubles - it worked under heavy use for 5 years and then died. After purchasing this gadget, I plugged it into my computer - it detected 2.4 and 5 GHz networks, but neither could be accessed. I installed drivers from the official site - nothing changed. I browsed forums and discovered the surprising news - this [censored] doesn't work out of the box. For it to operate correctly at 5 GHz, the router settings must have a channel selected from the list 36,40,44,48 - otherwise, it simply doesn't see the network. Also, it doesn't work with bandwidths higher than 40 MHz - the device can't connect to the network. Accordingly, the lower the bandwidth, the lower the speed. I couldn't return it - the inner plastic packaging was slightly torn. I tried to return it under warranty - the manager who filled out the form made a mistake and wrote 40 Hz. "I was sent to hell." I do not recommend it overall.
works stably at 2.4
5 GHz not working (works via [censored])

Better not buy this model
15 November 2021 
The adapter is extremely lousy. It was bought to work with the 5GHz line, but it works extremely poorly with it. It's more or less usable if you install the drivers from the disc included, rather than from the website.
if it works at 5Hz it turns out very fast
Very unstable

"Delivery" of the Internet from the router via a wireless channel is the main task shouldered by the compact Wi-Fi adapter TP-LINK Archer T3U. This miniature device significantly boosts the speed characteristics of accessing the World Wide Web in laptops with a poor Wi-Fi receiver or stationary PCs without it at all.

High speed performance

The model creates connections with a theoretical throughput of up to 400 Mbps in the 2.4 GHz band and up to 867 Mbps in the 5 GHz band. The connection of the device to the computer is implemented via the USB 3.2 Gen1 interface, which guarantees a more stable “flight” speed. The adapter provides trouble-free surfing on the Internet, fast downloading of large amounts of data, streaming video in resolution up to 4K, etc.

Line of sight

Place TP-LINK Archer T3U preferably closer to the router and in its line of sight. Walls and other obstacles on the signal path "cut" the data transfer rate due to the use of weak built-in antennas (one for each operating range of the adapter). Another of the reproaches to the model is the reluctance of the dongle to see 5 GHz networks on some routers. Usually this is "cured" by installing branded drivers from the supplied disk.

No extra fluff

The model supports MU-MIMO multi-stream data transfer technology. In conjunction with the appropriate router, the throughput and performance of the wireless network as a whole improves. TP-LINK Archer T3U has an adequate price tag, compact size, quietly and without unnecessary pathos performs a mission to improve the speed of the Internet "over the air".
