The manufacturer does provide a lifetime warranty, which can justify this additional expense.

This NET-DYN WiFi adapter is compatible with Windows and Mac computers and is supported by all WLAN routers. Security standards for this device include WPA, WPA2, and WEP. If you experience spotty or unstable connections, try downloading the current drivers. The size of this dongle also justifies an angled USB adapter plug if you intend to use this WiFi adapter with a laptop. This may still limit your access to other ports on your computer.

10. Alfa High Gain Wireless USB Adapter

If you are primarily concerned with achieving high gains, you might want to consider the Alfa High Gain Wireless USB Adapter. Even though this device only connects in the 2.4GHz band, it features two external antennas including a four-inch long 5dBi rubber screw-on antenna and a 14 inch 9dBi antenna. High transmitter power of 28 dBm supports high gain, long range wireless connections. This adapter does not plug directly into your computer but comes with a USB 2.0 cord.

If you want high output power, this model may be the best WiFi adapter for your purposes. The Alfa High Gain adapter provides up to 2000mw output power. The Alfa High Gain adapter is not compatible with routers that only broadcast “n” speeds on the 5.8GHz band or gaming systems. This adapter supports a wide range of security standards including WPA, WPA2, WPA-PSK, WPA II-PSK, IEEE802.1X, 64- and 128-bit WEP, Cisco CCX support, WAPI-PSK, and WAPI-CERT.

Buyer’s Guide

Compatibility

Some WiFi adapters are only compatible with Windows PCs, while other adapters include drivers that allow these devices to be used with Mac OS, Linux, and other operating systems. Make sure that the WiFi adapter you purchase works with your current setup, including your router, computer, and mobile devices. The bands of all of these devices must be compatible for an adapter to function as intended.

Frequency Bands

You may notice that some adapters are designated to function on certain bands. Some of these devices may only be functional on a 2.4GHz band or a 5.8GHz band, while others may be capable of receiving and transmitting on both bands. In addition to these increasingly common descriptions, you may also see these speeds described as 802.11 followed by a variety of letters.

802.11g only supports 2.4GHz and allows speeds up to 54 Mbps. 802.11n is a common dual band technology that supports speeds up to 600 Mbps. 802.11ac is exclusively in the 5.4GHz frequency band and allows for speeds of over 500Mbps up to gigabyte speeds. In general, the speeds possible on the 5.8GHz band can be up to three times faster than 2.4GHz technology.

Signal Strength

Signal transmission is considered in both directions, from the adapter to the router and vice versa. The transmission signal from the adapter to the router is referred to as the Tx level, the power in decibels per milliwatt or dBm. The signal from the router to the adapter is called the Rx level or received signal.

Mini or nano adapters will have considerably shorter internal antennas and are likely to lack the gain possible with a lengthy external antenna. Even if a smaller dongle boasts signal boosting technology or other features, the gain will probably not be as great as with an external adapter. Some WiFi adapters feature 5dBi antennas, though you may also be able to find 7dBi, 9dBi, or antennas that provide even greater gain.

The signal strength of an adapter tends to go up with the dBi rating of the antenna. If you are interested in boosting a wireless signal and allowing for faster speeds and more stable connections further away from your router, you should consider an adapter that has an external antenna with a high dBi rating.

Our Verdict

The best WiFi adapter for your needs will enable you to achieve the speeds you desire in the best bandwidth for your router and devices. Whether you want a USB adapter with a small profile or a model with high gain antennas, our ranking of the top 10 adapters can direct you toward the right connector for your home or office.
