What is a wireless LAN adapter?


The wireless LAN adapter is the device that connects your computer to your WiFi network. Wireless LAN adapters are sometimes built-in devices, but external adapters are much more common. This device is inserted into a USB port on your computer and the other end plugs into the wireless network.

To communicate with your wireless network, the adapter itself must have its own separate radio transmitter and receiver. These are built into the device so that it can send information back and forth between another radio antennae in your router—or access point (AP)—and your computer’s WiFi radio. The antennas on both devices are typically omnidirectional, meaning they broadcast and receive radio signals in all directions.

What is a wireless LAN adapter?

A wireless LAN adapter is a device that allows for the connection of a personal computer to a wireless network. The device plugs into the USB port on the laptop and links it to your wireless router so you can access the Internet wirelessly. The wireless LAN adapter consists of a small antenna, a radio transceiver and decoder chip, and some form of a platform that allows it to fit into the Universal Serial Bus (USB) port on the laptop.

A wireless LAN adapter is useful for people who want to access the Internet without wires. It can also be helpful in areas where physical cable access is not available. People who want to use their laptops in areas where there are no cabled network connections can access the Internet through a wireless router.

What are the most common types of wireless LAN adapters?

The most common types of wireless LAN adapters are USB dongles and PCI cards.

A USB dongle is a small device that plugs into the USB port on your laptop or computer. It allows you to connect wirelessly to a local area network (LAN) via Wi-Fi.

A PCI card is a circuit board that you install inside your laptop or computer, typically into an expansion slot on the motherboard. It allows you to connect wirelessly to a local area network (LAN) via Wi-Fi.

How to choose the right type of wireless LAN adapter?

One of the first things to consider when buying a wireless LAN adapter is the network standard (802.11a, 802.11g, or 802.11n). If you want to connect to a mixed-mode wireless network that integrates both 802.11g and 802.11n, then you should buy a wireless LAN adapter that supports both of these standards. The second thing to consider is what kind of Wi-Fi operation mode you want your device to be set to. Wi-Fi modes are usually set automatically by default but can be manually changed from time to time if needed. You have two main options:

1) Ad-hoc networking mode – this is for peer-to-peer connections where users may join or leave the network frequently.

2) Infrastructure networking mode – this is used for mobile users that need to connect via Wi-Fi to an access point (AP). An AP can be wired or wireless and is needed by mobile devices that cannot typically provide their own Wi-Fi network.

What are the common problems with wireless LAN adapters?

A common problem with wireless LAN adapters is that you might not be able to get a signal. It can be difficult to find the right position, and you may also need to upgrade the firmware on your router and adapter to make sure they’re compatible.

You can’t typically use a wireless LAN adapter without an internet connection, and they’re not as fast as Ethernet cables. However, there is usually no need to worry about security like with a wired LAN connection.

A wireless LAN adapter typically costs more than an Ethernet cable, and you’ll also need to make sure your computer has a wireless card that can support the speed of the internet. An Ethernet cable is often still faster, and it might be cheaper as well depending on the type of connection.

A wireless LAN adapter might not be compatible with some routers, and they’re also more likely to break due to a lack of physical protection. Wired connections are generally stronger and will never break while they’re plugged in.

How to fix a broken wireless LAN adapter?

First, make sure that there’s a cable plugged in from the router to the computer. Examine the cable for damage. A broken wire will show as a strand of copper poking out from where it has been severed.  If a cord does look damaged, replace it with a new one and then try connecting again.  Second, check that the Wi-Fi is on by clicking on Network or Wi-Fi settings in Windows or System Preferences on a Mac. In either case, if you have Wi-Fi disabled, turn it back on and reconnect to your network. If you can’t, try resetting or re-entering the network’s password.


Wireless LAN adapters are a type of device that can be used to connect to a wireless network. They come in both internal and external models, with the latter being more common for desktop computers due to their size constraints. The adapter will allow you to access your home or office network from up to 100 meters away, depending on the strength of the signal. There are many different types of wireless LAN adapters but they all serve one purpose: connecting devices wirelessly instead of using cables like Ethernet connections. It’s important when choosing which type is best for you and what your needs may be based on these factors: speed requirements (802.11b vs 802.11g), range requirement (Wi-Fi N vs Wi-Fi AC), and the frequency band (2.4 GHz vs 5 GHz).
