USB Wi-Fi adapters have varying features, so you need to know what to look for before buying the device that works best for you. These are the most important factors to consider.
If you live in a big home, the distributed spaces require an adapter that transmits a powerful signal to maintain a reliable connection from any part. The factor to check here is the antenna gain (given as a dBi rating).
The higher the rating, the stronger the antenna. For instance, a 5dBi antenna delivers a more powerful signal in long-range compared to a 2dBi type. The latter might work well in an apartment but will keep disconnecting if you move far away from the router in a large house.
That said, router positioning is another factor to consider, and you should place it at a central place in the house.
Single and dual bands refer to the signal frequency that the adapter uses to receive/transmit data. In most cases, single-band devices use 2.4GHz, while dual-band adapters use both 2.4GHz and 5GHz (the frequencies might vary slightly in the decimal figures).
A 2.4GHz band has a strong coverage over a wide area but transmits at slower speeds. On the other hand, a 5GHz band sends/receives at faster speeds but on a limited coverage range.
If you only need an adapter for regular internet use, such as internet browsing/surfing, small file downloads, and light office work, a single band type will do. However, for heavy internet use, such as 4K video streaming and lag-free online gaming, make sure to get a unit with a 5GHz band.
Ultimately, the dual-band Wi-Fi adapter is the best option because it gives you the best of both worlds. However, for you to enjoy the benefits of the two bands, your router must also be dual-band, so the two need to be compatible.
There are two ways of looking at the compatibility factor: the computer and wireless standards. Whether the adapter requires drivers or is plug-n-play, the software that runs it must be compatible with the operating system in your computer.
In most cases, Windows PCs are compatible, beginning from Windows 7. However, if you use a Mac or Linux PC, you must check whether the adapter supports it.
With wireless standards, the number 802.11 refers to the Wi-Fi protocols, and the letter(s) following it show which transmission protocol the device can use.
For instance, the protocol 802.11g (released in 2003) transmits up to 54 Mbps at 2.4GHz. On the other hand, the widely used 802.11ac protocol (released in 2013) has transfer speeds of up to 866.7 Mbps at 5GHz.
The router and adapter must operate using the same protocol for you to enjoy the full benefits of fast data transfer speeds.
If you travel a lot, it makes more sense to buy a compact USB Wi-Fi adapter. Keep in mind, though, that such a small size means limited hardware and inferior performance.
However, for home use, we recommend a device with all the powerful features. For instance, the two high-gain antennas in the Nineplus AC1200 increase the signal strength to ensure you get a strong connection at all times.
Lastly, there are two types of USB ports, and these impact the transmission speeds. USB 2.0 usually maxes out at around 60 Mbps, while 3.0 goes up to 640 Mbps.
Considering that all the data goes through the USB connector, an adapter with USB 2.0 will be slow even if it transmits at 5GHz (802.11ac). Therefore, we recommend USB 3.0, especially for HD video streaming and online gaming.
That said, the computer must also have USB 3.0 ports to transmit at these fast speeds. Old PCs might not have them, so 2.0 might be the best option.
How To Use A USB Wi-Fi Adapter?
As stated earlier, USB W-Fi adapters are either plug-n-play or require drivers. To use one:
- Begin by plugging it into your computer’s USB port
- Make sure you are close to the router to get a strong connection when setting up
- Select the wireless network
- Enter the password to connect
If it requires drivers, you will find a setup CD in the package or instructions on downloading the software from the manufacturer’s website. Install the drivers, then select the wireless network and enter the password to connect.
Once connected, the adapter should also link your computer to other devices on the network, such as your phone, smart TV, and consoles.
How To Increase Signal Strength of a USB Wi-Fi Adapter?
USB Wi-Fi adapters have a limited range, and if you notice the signal is weak, here are a few ways to boost the signal strength.
- Move your computer close to the router.
- Remove signal interfering items between you and the router. Metal furniture, microwaves, and thick doors either interfere with the wireless network or block it.
- If possible, change the router and adapter’s frequency band to 5GHz. Most electronics, such as cordless phones, use the 2.4GHz frequency band, making it prone to noise and interference.
- Update the adapter’s driver software to repair bugs and improve the firmware.
- Install a wireless repeater between the adapter and the router. It receives the wireless signals from both devices and boosts them to reach their destination.
People knowledgeable about networking hardware know there’s always a debate about which adapter is better. Well, PCI-e adapters are more powerful, give better reception, and sometimes have Bluetooth capability.
However, they have limited flexibility. After installation, it is not easy to remove the device to use it on another computer. It also needs some skill to install.
As for USB adapters, they are super easy to use. Installation is easy, and you can transfer them hassle-free between computers.
On the downside, they might not be as powerful signal-strength-wise, and their bandwidth might be limited. However, with USB 3.0, transmission speeds are much higher.
Final Thoughts USB Wi-Fi Adapters
To sum up, USB Wi-Fi adapters are convenient ways to access the internet wirelessly, and the one you should be looking for needs USB 3.0, a powerful antenna, and a dual-band with the latest wireless standards. You can also get a NAS adapter for a wired internet connection.
Of course, your computer’s specs will also determine the type of adapter you can buy. But since the goal is to improve your wireless browsing experience, you can upgrade your PC to be compatible with the best and fastest USB Wi-Fi adapter.
For instance, you can install an express card to give you USB 3.0 ports if your PC does not have them. Or an USB bluetooth adapters if your PC doesn’t have bluetooth.
