What is a Usb Wi-Fi Adapter?
Nowadays, it’s hard to imagine our lives without the Internet. We can get internet access through a cable or wirelessly. Of course, the second option is the most convenient. Unlike smartphones, not every desktop and laptop computer can connect to the Internet via Wi-Fi directly. For this purpose, USB Wi-Fi adapter was invented. It resembles USB flash drive as it also has a USB connector, but technologies differ. It receives signals from the access point, router, etc. Wi-Fi feature can be built in originally, in this case, there will be a special mark on a PC or a laptop. But if there is no integrated Wi-Fi card, the adapter will come in handy. We consider a Wi-Fi adapter the best way to get wireless connectivity and in this review, we will help you make the right choice.
What Features to Compare
Speed and Quality
When buying a USB Wireless Adapters, it is best to give a preference to up-to-date models that support the latest data transmission standards. Today, the recognized wireless standard is 802.11n, which guarantees data transfer at up to 300 Mb/s. Also, there are some newer ones: 802.11ac transmits data at a speed from 3000 Mb/s to 10 Gb/s, that is perfect for a large office or house. But commonly there is no need to pay extra money for the speed, as 300 Mb/s is quite enough for domestic use. You should also pay attention to the TX power of USB adapter. The optimal value is 20 dBm. It is an important parameter that provides a more stable reception of weak signals. If the appearance of the device doesn’t matter to you, it’s worth purchasing an adapter with an external antenna. They receive the signal much better but are often bulkier. Besides, there are devices with removable external antennas.
Another aspect to pay attention to is the protection and security of your Internet connection. Make sure your Wi-Fi adapter supports WEP, WPA and WPA2 protocols to sophisticated standards to safeguard your network. One more important thing is the support of multiple connection modes that can be established both from the access point to a computer and between two computers.
Connection and Control
Just as well, consider the type of device connection and control (or setting). Usually, all devices are connected via USB 2.0 and USB 3.0. If your laptop or PC is old and has only USB 2.0, the theoretical maximum speed is 60 Mb/s, while the USB 3.0 can reach 640 Mb/s upon a condition that your Internet provider or router allows such speed. If you want to turn your PC into a Wi-Fi hotspot, check whether the adapter has SoftAP feature. After installation, the adapter must be configured: install required software to perform wireless data transmission. The driver can be installed from a disc which comes with the device, or you can download it from the official site. After installing the driver, you need to configure the network, select necessary settings and access points; also, don’t forget to look at the compatibility with your OS.
NETGEAR AC1200 Wi-Fi USB Adapter
When using the Internet, we always want to have a fast and stable speed, and Netgear AC1200 can provide you such. This USB adapter has some features that distinguish it from its competitors. While most of the adapters support 300 Mb/s speed with a frequency of 2.4 GHz, the Netgear claims that its speed can reach 867 Mb/s at 5 GHz. Also, it uses Beamforming+ technology that boosts speed, range and reliability of the Internet connection, making surfing the Internet enjoyable to anyone. The 802.11n beamforming technology was created to enhance the range and data transfer rate between compatible devices that support this standard. However, Netgear states that they made some improvements in software to enhance speed and productivity. That’s how "Beamforming+" appeared. To get really good results, router and wireless adapter must be from Netgear company and support this technology. However, if purchasing the Netgear router isn’t in your plans, don’t write this adapter off. The research has shown that it also works pretty good with devices from other manufacturers.
We would like to draw your attention to the fact that besides the excellent productivity, this device has an unusual design and a number of interesting features. An uncommon antenna shape is the first thing you notice. It easily opens to increase adapter’s productivity. The Wi-Fi adapter itself looks pretty big, so it could fall out of USB port. But manufacturer took care of it: you can use the desktop dock with the attached cable that is supplied in the package. In this way, the productivity will be even higher as the adapter will be a little farther from a metal case, so no interferences will occur.
Undoubtedly, Netgear AC1200 can be considered one of the best wi-fi adapters in its class: with its high performance and versatile capabilities, it is perfect for large houses or offices.

How to Choose a Place for a Wi-Fi Router
Did you ever think about where to place a router for the highest level of emitted signal all over the building? Jason Cole, a Ph.D. physics student at the Imperial College of London did. He decided to experiment: he didn’t just walk around the apartment with the router and measure the signal strength, he used his scientific knowledge. To do the calculations, he used the Helmholtz equation which can resolve physical problems in space and time, and simulated his flat in a program. He also took into account the reflection coefficient of walls, closed doors, and corners. If you’re interested in details about how the experiment was done, take a deeper look at Jason Cole’s blog post. Cole concluded that putting a router near the center of your home was likely the best solution to get the highest Wi-Fi signal. Now you also have a possibility to map your own signal thanks to Cole’s Android app: just take a floorplan of your house, set the location of a Wi-Fi router, and finally get the answer where your router should go.

Wi-Fi is a technology that allows computers to connect to a wireless network using radio bands. The technology was created in 1991 in the Netherlands. A Wi-Fi logo in public places indicates to the citizens that a location is within the range of a Wi-Fi. Initially, it was created for cashier systems, but after a while, the creators realized all the benefits of their invention, and Wi-Fi was delivered to the masses. Don’t rack your brain trying to figure out what "Wi-Fi" stands for; it isn’t an acronym, it’s just a pun upon the word Hi-Fi. Today, Wi-Fi is one of the most widely used internet connections. It is recommended to be installed where running cables is impossible or unprofitable. Nowadays, a lot of organizations use Wi-Fi, as under certain conditions the network speed exceeds 100 Mb/s. Also, users can move between access points in Wi-Fi coverage area.

As we know, any computer can get infected with a virus through the Internet or file exchange via removable media. However, researchers from the University of Liverpool developed a virus that travels over Wi-Fi networks via access points! They simulated an attack of the virus, which they called "Chameleon", and found out that it didn’t affect the work of access point, but collected and reported all the information about users who connected to it. If the virus hits the networks protected by passwords, it automatically searches for open access points and moves to them. Simulations took place in Belfast and London; they showed that just like a human cold spreads faster in a crowd, the virus spreads faster downtown, where a large number of public places are located. Unfortunately, there is no good protection from this type of virus that makes Wi-Fi networks an easy target for hackers. To reduce the risk of getting infected, we strongly recommend you to avoid public Wi-Fi hotspots. As for home routers, give the preference to the one which supports WPA/WPA2 security protocols and be sure to change the default username and password on your home network.
