In our fast-paced digital world, reliable, high-speed connectivity is essential – especially if using an older laptop that doesn’t have 5G capabilities built-in. The ASUS Dual-Band AC1200 USB Network Adapter promises to keep you on top of this need, offering a compelling blend of speed, versatility, and convenience.

A Detailed Look at the Product

ASUS Dual-Band AC1200 USB Network Adapter

This sleek, black USB network adapter from ASUS connects directly to your computer’s USB port. It offers dual-band functionality (2.4 GHz and 5 GHz), enabling flexibility for longer-range connectivity or higher data transfer rates.

The theoretical bandwidth of 1200 Mbps is split between these two bands, supporting the advanced 802.11ac wireless standard, an upgrade from the older 802.11n.

User Experience

Ease of use is a standout feature of the ASUS AC1200. Simply plug it into a USB port, and your computer gains wireless capabilities. This proves particularly beneficial for those with older computers lacking built-in wireless cards.

The dual-band functionality adds another dimension of versatility. Depending on the user’s needs, they can opt for the 2.4 GHz band for longer range or the 5 GHz band for faster data rates, with speeds reaching up to 867 Mbps. This is perfect for high-bandwidth activities like streaming, gaming, and large file transfers.

This network adapter adapts effortlessly to networks supporting the 802.11ac standard, delivering improved performance and reliability. It’s worth noting that while its theoretical speed is impressive, the actual performance can vary due to factors like distance from the router, signal obstacles, interference, and the capabilities of the connected device.

Despite these limitations, the ASUS AC1200 offers a smooth, enjoyable internet experience, providing a user-friendly and reliable solution to your connectivity needs.

Pros and Cons


  • Dual-band functionality: It provides flexibility in choosing between the 2.4 GHz band (better range, but potentially more congested) and the 5 GHz band (faster data rates, but shorter range).
  • High-speed connectivity: With theoretical bandwidth up to 1200 Mbps, it can handle high-demand tasks such as gaming, streaming, and large file downloads.
  • USB connectivity: Easy installation without the need for internal component installation makes it widely compatible, especially for older computers.
  • Support for 802.11ac: This ensures a smooth and stable internet experience, providing an edge over older wireless standards.


  • USB 2.0 limitation: The lack of USB 3.0 support might limit the adapter’s performance, particularly with devices supporting higher data rates.
  • Variable wireless speeds: Real-world wireless speeds can fluctuate due to numerous factors.
  • Limited advanced features: Lacks features like MU-MIMO technology compared to competitors, potentially reducing performance in multi-user environments.
  • Size: Slightly larger than some alternatives, potentially affecting portability and visibility when plugged into a laptop.

How It Stacks Up Against the Competition

When comparing the ASUS AC1200 with similar products like the ASUS USB-AC53 Nano, some noteworthy differences emerge. Both share dual-band functionality and impressive speeds, but the Nano trumps in portability and advanced technology support, like MU-MIMO.

The Nano falls behind the AC1200 in performance, especially on the 2.4 GHz band. For users prioritizing speed over range, the AC1200’s strong 5GHz performance makes it a compelling choice. It’s also worth noting that the AC1200 is a USB 2.0 device, whereas the Nano can potentially deliver better performance with USB 3.0. While the AC1200 typically commands a higher price, its superior 5 GHz performance might justify the investment.

Is the ASUS AC1200 Worth Buying?

The ASUS AC1200, with its array of features, offers a solid investment for enhancing your wireless experience. Its competitive price, coupled with features usually found in higher-end models, makes it an attractive proposition.

The dual-band functionality allows users to tailor their wireless connection based on their needs. Moreover, its high theoretical bandwidth promises an impressive internet experience. Add to this the easy-to-use USB connectivity, and the product delivers significant value.

Bear in mind the variable wireless speeds due to external factors. This doesn’t detract from its inherent value but is important for a realistic assessment of the product’s performance.

The ASUS AC1200 offers substantial value for its price point. Its dual-band capabilities, high-speed data transfer, and simple USB connectivity make it a cost-effective choice for a wireless connection upgrade.
