Model overview based on user reviews  
The TP-LINK Archer T4U Wi-Fi adapter offers a dual-band connection with support for Wi-Fi standards up to 802.11ac, providing wireless speeds of up to 867 Mbps on the 5 GHz band and 300 Mbps on the 2.4 GHz band. It connects via a USB 3.0 interface, ensuring compatibility with older USB versions. Users have noted that while the adapter provides stable performance and good speed, its large size can block adjacent USB ports. Additionally, some users experienced issues with the official Linux driver, though alternatives are available. The adapter's internal antenna may require positioning close to the router for optimal signal reception, aided by an included extension cord. However, some users reported signal drops and overheating, leading to dissatisfaction. Overall, the Archer T4U is a capable adapter with certain limitations that potential buyers should consider.
Pros

Cons

Can be taken

I have a flip model. It's quite large and covers the neighboring USB port.

By default, the Ubuntu driver didn't load, so I had to compile it from source. The official driver didn't compile, but https://github.com/morrownr/88x2bu worked.

The speed is good, and the reception is stable too. In the corner of the room where the old adapter was barely coping and sometimes cutting out, this one shows 30/40 Mbps on 2.4Ghz (repeater 5m away) and 40/60 Mbps on 5Ghz (to the router ~10m, through walls).

Absolute junk. I bought it for my PC, 5 meters from the router through the wall in the next room. Constant signal drops, speed fluctuates, heats up. I returned it to the store the next day.

Video reviews

The TP-LINK company has eaten more than one dog in the production of all kinds of network equipment. A device named Archer T4U expands the capabilities of a PC or laptop by connecting it to the World Wide Web without wires(unless, of course, there is a working router in the house).

High speed communication

The device, which looks like a large USB flash drive, has acquired support for the 802.11ac standard, along with which we can talk about high-speed data exchange. At a frequency of 5 GHz, the adapter puts the arrow of the speedometer at around 867 Mbps, and in the 2.4 GHz band, speed characteristics are limited to 300 Mbps. The adapter is connected via a USB 3.0 port, maintaining compatibility with previous generations of the interface.

Gloss and shine

The glossy body of the device, which is prone to scratches due to careless handling, has a WPS button to enable connection protection, as well as an LED indicator of the adapter status. It illuminates a green strip of transparent plastic. Due to the relatively large size, the device sometimes blocks access to the adjacent USB connector with a heap of ports on the computer connection interface panel.

Extension cord for confidence

The internal antenna imposes some restrictions on the quality of signal reception. Wi-Fi adapter should preferably be located in the line of sight of the router. To help a little in this matter, a complete extension cord with a metre-long cord is called upon to optimize the position of the device and its antenna. The closer the adapter is to the signal distribution source and the fewer obstacles it encounters, the more confident the reception will be.
