6 Best USB WiFi Adapters

1. TP-Link Archer T9UH

TP-Link Archer T9UH USB WiFi Adapter offers fast 5GHz speeds that enhance signals through walls with minimal performance loss. Compact at just 0.5mm thick and 3.5 inches in length, the USB 3.0 Cradle offers stable connectivity on 5GHz networks for reliable performance, while limited 2.4GHz support.

Pros:

• Excellent 5GHz speed and coverage.
• USB 3.0 cradle for flexible placement.
• Stable connection with beamforming tech.

Cons:

• Poor 2.4GHz performance.
• Bulky design.
• Slightly expensive for its category.

2. Netgear Nighthawk AC1900 WiFi USB Adapter

Netgear’s AC1900 USB WiFi adapter is both massive and sturdy. However, its cost exceeds its quality. When folded shut, it measures just 0.75 millimeters thick by 4 inches long before unfolding up to 7.5 inches of cord length for full support of slim laptops. Luckily, it comes with an extremely sturdy USB dock that’s magnetic, so you can place it on a nearby surface (not for all laptops).

As with the Archer T9UH, my Nighthawk performed well when connected to my 5-GHz 802.11ac network. However, once in 802.11n mode, its adapter could no longer detect my router’s 2.4GHz option when placed next to it on opposite walls. It offered the largest average 5GHz boost, averaging 13dB. However, the T9UH was a bit better on speed loss.

Pros:

• Strong 5GHz performance and wide coverage.
• Durable, premium design with a stable dock.
• Excellent for gaming and 4K streaming.

Cons:

• Bulky and heavy.
• Poor 2.4GHz connectivity.
• High price point.

3. D-Link DWA-X1850 Wi-Fi 6 USB Adapter

The Wi-Fi 6 first USB adapter expands the 2.4GHz spectrum. However, it doesn’t offer a breakthrough speed. As we used the DLink AX1850 with a WiFi 6 router and assessed its signal strength, its theoretical advantages over WiFi 5 units became evident. But, due to it being an AX1800 model slower than competitors’ AC1900 versions, these theoretical advantages did not translate to actual speed increases from distance.

Pros:

• Wi-Fi 6 for faster and more efficient connectivity.
• Smooth setup and reliable performance.
• Great for multi-device environments.

Cons:

• Minimal real-world improvement over Wi-Fi 5.
• Limited macOS compatibility.
• Short range compared to AC1900 models.

4. TP-Link Archer T4U Plus

The Archer T4U Plus sits at the perfect cost and performance. The T4U Plus USB WiFi adapter does not directly plug into your computer. Instead, it features an adapter with two 6-inch antennae attached to a trapezoidal form factor and connected using its supplied USB cable for use with T4U Plus’s AC1300 standard.

The T4U Plus reliably connected to both my 5GHz and 2.4GHz networks, delivering me an average signal boost in the range of 6.5dB in the frequency range 5GHz. The Wi-Fi performance in my office and elevator is much better than it was on my laptop. The difference was evident. In the elevator, speed reductions dropped from 95% when using the laptop to 69% using this USB WiFi adapter. If you want to squeeze out more Wi-Fi speeds for a small cost, the T4U Plus does the trick.

Pros:

• Dual antennas provide excellent range.
• Strong dual-band speeds for the price.
• Reliable and consistent connection.

Cons:

• Slightly bulky design.
• Lacks Wi-Fi 6 support.
• Needs USB cable — not fully portable.

5. TP-Link Archer T3U Plus

TP-Link’s basic adapter is a small USB WiFi adapter equipped with a rotatable antenna and 7 inches in length, perfect for connecting directly to both Mac OS and Windows computers for testing purposes and seeing what comes of them. This is the purest and simplest method of “sticking a big antenna on something and seeing what happens.”

AC1300 adapters allow two streams of data on either 2.4GHz or 5GHz frequencies and provide a slight but noticeable boost to signal strength in my home office. But they didn’t make a large dent in the signal loss caused by elevators. Neither did any harm come from them, and neither made an obvious, impactful statement about their effectiveness or otherwise.

Pros:

• Compact and budget-friendly.
• Adjustable antenna for better signal direction.
• Easy installation on Windows and macOS.

Cons:

• Average performance on long range.
• No USB cradle for repositioning.
• Not ideal for heavy streaming or gaming.

6. BrosTrend 1200Mbps Long Range USB WiFi Adapter

This off-brand adapter is poorly produced and generic. The adapter is an AC1200 adapter that comes with two analogs that rotate. You can plug it directly into your computer or use the dock included. But it is the case that the USB dongle isn’t plugged completely into its dock, leaving part of the connectors exposed.

The BrosTrend adapter’s performance is worse than I anticipated from a device that has two antennas. It averaged a 5.75dB more signal at 5GHz compared to the laptop by itself, and was higher than the Archer T3U and worse than the TP-Link and Netgear adapters as well. It also suffered from lower connectivity speed than these TP-Link and Netgear adapters, but it was still superior to the laptop on its own. If you decide to purchase a USB WiFi adapter like this, you could consider it to be good, but it’s because you haven’t tested anything else.

Pros:

• Dual-band support (2.4GHz + 5GHz) for fast speeds.
• High-gain antennas improve range and signal stability.
• USB 3.0 interface ensures faster data transfer.

Cons:

• Limited Linux support; may require manual drivers.
• Build quality concerns with long-term durability.
• Performance can vary depending on the environment and hardware.

Buying Guide: How to Choose the Best USB WiFi Adapter

• Wi-Fi Standard: Choose Wi-Fi 6 for faster speeds and future-proofing. Wi-Fi 5 is enough for basic use.
• Bands: Dual-band (2.4GHz + 5GHz) covers most needs; tri-band adds extra channels for less interference.
• Antenna: External or high-gain antennas improve range and stability.
• USB Version: USB 3.0 is faster and better for high-speed adapters.
• Compatibility: Check OS support for Windows, macOS, or Linux.
• Use Case: Gaming and streaming need high-speed adapters. Casual browsing can use compact, budget options.

Conclusion

Upgrading your laptop or desktop with a USB WiFi adapter is a fast, affordable, and effortless way to improve internet speed, signal range, and create stable connections for streaming videos, online games, work, or other online activities. From high-performance options such as the TP-Link Archer T9UH adapter to budget options like BrosTrend 1200Mbps adapters, there should be something suitable according to your budget. Find one that meets your Wi-Fi standard range requirements and device compatibility needs to get the optimal online experience.
