    Reviewed in the United States on August 13, 2023
    I recently purchased the TP-Link AX1800 WiFi 6 USB Adapter for Desktop PC (Archer TX21UH), and I'm genuinely impressed with its performance. I would confidently rate it a perfect 5 out of 5 stars.

    This WiFi 6 USB adapter offers a seamless wireless network experience, providing support for both 2.4GHz and 5GHz frequencies. The inclusion of advanced features like MU-MIMO and OFDMA further enhances the efficiency of data transfer and reduces latency, ensuring a smooth and reliable connection.

    The high-gain dual-band 5dBi antenna significantly improves signal strength and coverage, contributing to a more consistent and robust wireless connection. The WPA3 security protocol adds an extra layer of protection to your network, enhancing overall security.

    The compatibility with Windows 11 and Windows 10 ensures that it integrates seamlessly with your desktop PC's operating system.

    While I found the TP-Link AX1800 WiFi 6 USB Adapter to be an excellent choice for enhancing wireless connectivity, I eventually returned it. My decision was solely based on my personal preference for a WiFi 6E-capable adapter. However, I must emphasize that this TP-Link adapter offers exceptional value for its price point.

    In conclusion, the TP-Link AX1800 WiFi 6 USB Adapter (Archer TX21UH) is a high-performing and cost-effective solution for upgrading your desktop PC's wireless capabilities. While I opted for a different adapter with WiFi 6E capabilities, I wholeheartedly recommend this TP-Link adapter to anyone seeking an outstanding WiFi 6 experience without breaking the bank.

    Sincerely,
    Mark

    The setup was very easy. I already had wifi on my mobo, so I just downloaded the driver from their site. Then I disabled the mobo wifi in device manager and restarted the pc. The only frustrating part was finding a good signal. I had to keep moving it around because the wifi would keep disconnecting from the router. Eventually, I did find a good signal.

    My first TP-Link device after years of NetGear. Wanted a newer USB 3.0 adapter for better performance. Win10 with all current updates. TP-Link adapter installed easily, downloaded the driver from their website, and was up and running with decent speeds (though only marginally better than my old USB 2.0 adapter). The next day the disconnects started. Windows troubleshooting said a possible problem with the driver. It froze trying to uninstall the driver. It froze trying to reinstall on top of the existing driver. PC would not respond to Restart or Shut Down commands and required a hard shut down (power off). No PC-based monitoring app available. First level technical support couldn't offer any suggestions. 2nd level support offered a remote session from the Philippines with a 14 hour time difference. I provided available time options with no response. No 2nd level support offered during regular U.S. business hours?! The Wi-Fi adapter is unreliable and basically useless. I will buy another NetGear adapter. Wasted $60. (Note: Disconnected while trying to write this review. After a reboot the driver was gone. Reinstalled the driver and it came back again. But for how long?).

    Just purchased a refurbished Dell OptiPlex 7050 Micro Intel i7-6700T computer from EBay. It came with a cheap wifi dongle - after booting the new PC, the network connection was extremely weak and slow (it would drop all the time).

    I went a head and purchased the TP-Link AX1800 WiFi 6 USB Adapter -- amazing. The wifi doesnt drop and more and I am getting in excess of 120 Mb / second over wifi now.

    This purchase was worth every cent I paid for it. Really i can recommend this product.

    This device was very simple to install: just plug it in a USB 3 socket and you're set. I am on Windows 10, and my internet speed went from 15 Mps using another device that used the house electric wiring as network, to 300 Mps wireless. Excellent investment. My computer is more than 5 years old, and it worked without a problem.

    Works great. Had one hiccup during installation of driver software.
    This happens if you insert the USB adapter while a Windows update is waiting in the queue. For some reason the installation of the Wifi driver fails. After installing the Windows Update the Wifi Adapter does not show the installer anymore. When this happens copy the installer to a folder on your computer before running the Windows Update. If you forget this step, you can download the installer from the TP-Link website. URL is in the small document that comes with the Wifi Adapter.
