Main Varieties USB or PCI?

First, it is necessary to determine which interface you will use to connect the adapter to the computer.


The most popular is a portable receiver with a USB plug. In size, such devices do not differ from larger flash drives, so you can carry them in your pocket or even on a key ring.

Adapters that use the USB interface are ideal for those who often use separate computers and laptops because they are often designed to reconnect.

However, such receivers have severe disadvantages – models with external antennas are very rare, so the range of wireless connections will be minimal.

Also, you can connect the adapter to the PCI Express connector, which is located on the computer motherboard. Such a receiver is a network card with a computer’s ability to function in a traditional wireless network.

The PCI Express interface provides a better power supply for the module, so it will be easier to connect the PC to Wi-Fi, even if the router is sufficient. Embedded adapters usually have internal or external high-power antennas, so they will not have any serious problems with connection quality.

You can buy a receiver installed in the PCMCIA expansion slot or its analogs from various electronic device manufacturers for laptops or modern net-top computers.

This type of Wi-Fi adapter is externally an extended card, devoid of any protrusions (such as a model with a USB plug, can place it in your pocket). The unique advantage of the PCMCIA interface is installing an additional module without restarting the computer and the absence of parts, unlike USB adapters. However, the problems are the same – the underlying antenna cannot ensure stable reception of information at a great distance from the router.

USB WiFi Adapter

When You Search Online Or Offline For A WiFi Adapter, The Retailer Gets To See You Two Types Of Adapters, One With Standard USB And The Other With Pci Card. The Most Essential And Primary Difference Is How The Two Connect With The Computer.

How To Choose WiFi Adapter

The USB Adapter Performs A Little For Convenience, All Of Them Are Small, And They Are Easy To Install. They Also Have A Reason To Like Them Portable.

However, Many USB Adapters Have Come In Small, Portable, And Antenna Free, And Their WiFi Network Capabilities Go To Dual-Band Wireless-N Networking.

PCI WiFi Adapter

On The Other Hand, PCI Adapters Are Known For Maximum And Good Wireless Connections. Pci Adapters Come With Multiple Antennas And Spatial Multiplexing For Maximum Wireless-N Throughput. Installing Them Is Not Difficult, But A Little Complicated.

PCi WiFi Card

Choosing Between A USB Adapter And A Pci Card Depends On What Is Most Important To You For The Contractor’s Performance. The Choice Between The USB Adapter And The Pci Card Depends On What Is Essential For You Regarding Convenience Or Performance.

Of Course, If You Want To Buy An Adapter For A Laptop, Then The WiFi USB Adapter Will Be The Best Option For You. I Have Tested All According To The Price To Performance And Have Sucked In The Ten Best WiFi Adapters That Justify Their Price And Give The Best Performance.

I Have Also Written A Blog On It, “10 Best USB WiFi Adaptors For Pc: Buying Guide,” Which You Can See To Help You Buy The Right WiFi Adapter For You.

What To Look For In A USB Wireless Adapter

Type Of USB Ports (2.0 Gen Or 3.0 Gen)

Type Of USB Ports 2.0 Gen Or 3.0 Gen

You Can’t Judge A Wireless Adapter Based On Its Appearance. Just Because Both USB Adapters Look Alike, It Does Not Mean That Both Have The Same Performance, And Not Because One Has Two Antennae And One Does Not Have Any Antenna. It Does Not Mean That The First One Is Better Than The Antenna Adapter Without The Antenna.

If You Want To See Which USB Port Is On Your Laptop Or Computer, Then If You Bought The Laptop Or Computer 3 To 4 Years Ago, There Are More Chances To Have A 2.0 USB Port. USB 2.0 Port Looks Like Standard Ports, And USB 3.0 Port Comes In Blue Color.

What Difference Does Our WiFi Adapter Make From Both Ports? If You Use A 2.0 USB Port, Then The Maximum Speed You Will Get Will Be 60mb/S, But If You Use 3.0 USB, Then The Top Speed You Will Get Rate ​​Will Be 640mb/S

Wireless Protocols

As I Mentioned In The Previous Section, How Much Port It Keeps. Similarly, It Is Essential To Make Sure That Your Router Supports Which Protocol. If It Supports 802.11ac, Then You Can Use A 3.0 USB Port. If Your Broadband Subscription Is Below 60 Mbps, It Is Not Essential To Choose Any Protocol Other Than 802.11ac.

Wireless Protocol 802.11b, 802.11n Or 802.11ac

The Number Of All Wireless Routers Is 802.11. The Letter That Follows This Number Is The One That Determines The Transmission Protocol That The Router Supports.

The 802.11b Router Provides The Smallest, Least Distance, And Slowest Connection, While 802.11ac Will Give The Relationship With The Most Comprehensive And Fastest Connectivity.

The Key Here Is To Make Sure The Adapter You Choose Can Transmit An Equivalent Protocol As Your Router. If You’ve Got An 802.11ac, As An Example, You’ll Want An 802.11ac Wireless Adapter.

802.11n Or 802.11ac Is Typically Recommended For Users Buying Both The Router And The Adapter To Make Sure Fast And Reliable Connectivity.

WiFi Wireless Frequency Bands: 2.4 Ghz Or 5 Ghz

Most people make the mistake of purchasing a Wi-Fi receiver for a desktop computer. They are sure that all devices, without exception, use standard parameters, so there is no significant difference between them. This is incorrect since adapters vary in signal strength, determining the reception’s quality over sufficiently large distances.

A standard indicator for modern homes and middle offices is a power of 20 dBm. If it is low, it would be possible to connect PCs to Wi-Fi networks only in a small apartment using such devices.

Antenna gain is also significant – the higher the reception scope on the computer. However, it is unnecessary to pay attention to intangible values because such adapters would be expensive.

Moreover, they would consume a lot of energy. To connect your PC to a wireless network via a USB receiver, you should choose a model with a gain of 2dBi, and for devices embedded with an external antenna, you need to be guided by a figure of 5dBi.

Finally, you need to pay attention to the wireless standards that the adapter supports. It is necessary to leave devices using connection B or G immediately – they do not provide data transfer with speeds greater than 16 Mbps.

Despite the apparent obsolescence of such communication standards, many manufacturers still produce USB receivers that support them. There is only one case to get such models – when you are looking for a cheap device, you will use very little.

To connect your computer to a global network at sufficiently high speeds, select an EN standard adapter – its maximum bandwidth reaches up to 300 Mbps. The practice suggests that this is sufficient for watching movies online, downloading large media files, as well as the Internet and other purposes.

And only if you use your PC with professional applications or for ultra-modern online games, you’ll need to buy an AC standard receiver that can transmit up to 10 gigabits per second. Searching for USB adapters that support Wi-Fi AC is practically useless – it is quite expensive and usually comes in embedded modules.

Remember that purchasing a receiver that does not conform to the Wi-Fi standard used by your router is useless. Even if you buy the latest device using the high-speed data transfer protocol, the G-Type router will not allow you to connect your computer to the Internet at speeds greater than 16 Mbps. Therefore, before purchasing an adapter, you should look at the characteristics of the existing wireless network.

As We Mentioned In The Previous Section, How Important Is It To Ensure A Correct USB Port? The Band They Support At 2.5ghz, And 5ghz(Dual-Band Adapters) Also Matters A Lot Here. 

Both Frequencies Have Their Strengths And Weaknesses. It Would Be Best To Do Some Research Before Making Your Choice.

If You Have Many Walls In Your House And Use A Lot Of Wireless Equipment Around You, There Will Be A Lot Of Interference In Your WiFi From Other Wireless Devices.

Then You Go To The 2.4 Ghz Frequency Because Most Wireless Devices Operate On The 2.5 Ghz Spectrum. This Means That There Will Be Less Frequency Interference Of 5.0 In Your Network.

However, If You Suck At 5.0 Ghz Frequency, The 5.0 Ghz Transmission Suffers From Signal Loss For Long Distances.

Some Modern Adapters Support Both 2.4 And 5.0 (Dual-Band Adapters) Simultaneously, So You Can Buy Any Of Them And Use Them At Your Convenience. Some WiFi Adapters Have A Post Written On Them. You Can See

Adapter Build Quality

The Market Is Replete With Low-Quality WiFi Adapters That Promise Excellent Performance, But Their False Promise Lasts For A Few Days Or Months.

When Buying An Adapter, Please Pay Attention To Its External Construction. Go To A Useful, Reliable WiFi Adapter Buyers Guide And Choose The Adapter That Offers The Best Balance Between Quality And Price And Cost.

External receiver

To connect your PC to a wireless network, choose the D-Link DWA-127 receiver. Unlike many analogs that use a USB interface, it is equipped with a full-size antenna, which provides excellent signal amplification. The adapter can operate at any distance from the router without dropping the data transfer rate.

Of course, for USB receivers, an external antenna is not only an advantage but also a significant disadvantage – it would be inconvenient to carry it in your pocket. However, when connected to a stable PC, this problem is unlikely to be relevant.

An adapter that supports the EN data transfer standard is a reasonable solution, given its wide distribution in modern electronics and the limited bandwidth of the USB 2.0 interface.

In its case, there is a WPS key, which is designed to connect to the router in automatic mode. Such a device would be an ideal choice for a modern computer equipped with a sufficient number of USB ports – it provides a stable connection and does not require any effort to set up.

Built-in model

The phrase “cheap and angry” adapter is the best way to describe the ASUS PCI-N10. This model’s cost is around 800–1000 rubles, but in terms of its parameters, it is not less than its counterparts, which is 3 to 5 times larger. The device’s main advantage is to use a special technology that allows you to install it as a virtual router to which you can connect another computer or mobile device. Small enterprises often use such a scheme – to expand the reception radius of Wi-Fi networks, not using expensive routers but adapters for desktop computers.

The device supports the EN data transfer standard and provides connection speeds of up to 300 Mbps. The PCI Express slot has a large bandwidth, so there will be no delay when viewing online multimedia content. The user can connect the computer to a wireless network using any data encryption. There is a WPS button on the back panel of the adapter, which is designed for automatic connection with the router.

USB WiFi Adapter Size

At The Beginning Of This Article, I Told You That Some WiFi Adapters Are Bulkier Than Others, Some WiFi Adapters Are Smaller Than Others. It Depends On Your Computer Setup Determines How Big A WiFi Adapter You Can Go.

USB Ports Are Standard Break Feet Close To Each Other, And If You Find A Bigger WiFi Adapter There, Then There Is A Problem In Installing Another Device.

Suppose You Are Going To Install Any Other Equipment. So You Should Buy An Adapter That Can Provide Enough Space To Install Your Other Device.

Apart From This, If You Are Using A Laptop And Buying An Adapter For It, Then A Small Dongle Would Be Best For You Because One Will Be Portable Due To Being Small And Fear Of Breaking The USB Port Laptop. It Will Also Be Less.

Modern option

For users who appreciate the versatility of any device, the joint adapters are now available. They provide a stable wireless connection that complies with Wi-Fi and Bluetooth standards and supports Airlink, Apple Airplay, and many others. Besides, stores also often have adapters designed to establish direct connections with mobile devices without a router’s involvement – they are built using WiMAX technology or Wi-Fi Direct.

However, only users who own multiple mobile devices and home electronics, which are controlled via wireless communication, can make sense of receiving them. In other cases, it is better to give preference to the options mentioned above, as they add themselves to benefits such as practicality, economy, and ease of installation.

What to look for whenm choosing wifi adapter

First of all, we look at standards and speed. There are many standards in the world.

What to look for whenm choosing wifi adapter
What to look for whenm choosing wifi adapter
  1. 802 11. A – Not applicable to the territory of Russia. Its range is small, but throughput is good – up to 54 MB / s. Not worth buying because there are no tools to work with.
  2. 802 11. B – Speed ​​(11 MB / s) and security for this standard leave much desired. The radius of action is up to 50 m.
  3. 802.11i is the modern standard. It uses modern data encryption. The speed is 125 mb / s, and the radius is 50 m. WEP, WPA, WPA2 protocols are included.
  4. And the final standard for today is 802 11.n. The data transmission is at a speed of 540 mb / s, and the coverage radius is up to 200 m. Security is high.
  5. For a regular user, the device will fit with the 802 11g standard. These cheap gadgets allow you to enjoy surfing the internet, watching movies, and playing online games.

The other thing we focus on is router compatibility. It is better to buy adapters from the same company as the router. This way, you can avoid many problems when connecting incompatible devices.

The frequency at which the adapter is running. As mentioned at the beginning of the article, each adapter operates at its frequency. There are only two of them: 2.4GHZ, 5GHZ. Since 2.4 GHz is widely used today, it is best to buy a 5 GHz adapter.

After you are satisfied with the listed parameters, you pay attention to the transmitter power and the number of antennas. It is not recommended to buy it with a capacity of less than 20 dBm. The signal will be weaker and will also reduce the distance covered. It is advisable to purchase a device with two or more antennas. And even with an external antenna \ u200b \ u200b, the device receives and transmits a signal optimally.

Antennas are divided into directionality and polarization, narrowly directed, ubiquitous, and regionalized by focusing.

  • Semantic: Antennas propagate a signal in the form of a narrow beam. The width of the chart ranges from 5 degrees to 15 degrees.
  • Sectoral: spread the signal over a certain area: vertical 15 degrees, horizontally from sixty to one hundred and twenty. They are used when you need to connect a large number of clients.
  • These are omnidirectional antennas that propagate the signal 360 degrees.
  • Polarization antennas are divided into two types.
  • Unipolar: They use a connection connector.
  • Bipolarized: The connection is made using two connectors. Such antennas have a strong signal because transmission is performed in two currents: vertically and horizontally.

Also, the device must support encryption such as WPA / WPA2, WPA-PSK / WPA2-PSK. These are modern safety standards.

The longer the transmit-receive limit, the better.

The main mistakes when choosing a wifi adapter

When choosing the most serious and first mistake, it has a beautiful appearance and an affordable price. Almost no one pays attention to its features. This cannot be done while purchasing this device.

main mistakes when choosing a wifi adapter

Another mistake is based on stereotypes – all Chinese techniques are bad. Quality depends on the model and not on the firm.

When buying in the first place, read the specifications, review the device, and then conclude.

One of the most common mistakes people make when shopping for a new device is that they rely on sales assistants. The seller does not, as a rule, try to sell a model that suits the characteristics of others, but for which it can get its interest.

Therefore, before purchasing, it is recommended that you familiarize yourself with the functionality of the selected models and read reviews about them on the Internet.

Another mistake that people think of all adapters is that they are very much the same. Different models differ from each other in strength, characteristics from the same manufacturer.

Many people ensure that there is no need to spend money on expensive equipment. Of course, you can buy an inexpensive device, but its power will be much less than this, for which you only have to pay more than a few hundred.

Furthermore, it is also one of the biggest misconceptions that all equipment manufactured in China lacks poor quality. The quality of the products does not depend on where the manufacturer is located, but who ordered these products’ manufacture.

As practice shows, any user can configure a wireless network. Wifi adapters are reliable devices that are becoming indispensable to people. You can save many inconveniences by purchasing adapters such as multiple wires.

In today’s high-tech world, everyone needs to know what a wifi adapter is. We all use wireless networks continuously to solve various problems, but none of us think about how such technology works. Why know this?

Knowledge helps solve all possible connection problems. Furthermore, such knowledge helps to understand the operation of some devices better. But before proceeding to the answer to the question of wireless wifi adapters, you must understand what it is and how it works.

What are the best ones to buy?

In this article, we have tested many lift adapters, both USB and PCI, and you can reach our ranking. The best are USB pick adapters, where you will get all the analysis in-depth and by rating.

Before purchasing any of them, we should pay attention to their technical specifications, Wi-Fi versions, Life Class, whether it supports 160MHz or not, and even have external or internal antennas.
