Alfa wireless adapter hacking

To relieve that stress, 5 GHz was introduced to offer fast Wi-Fi connections over similar distances as a comparable 2. For hackers going after Wi-Fi devices, a router that provides both 2.

In the United States, 2. While it may seem like a lot of room, the truth is that all but three of these channels overlap with each other, causing issues with interference and slow speeds when too many devices are on the same channel. The reason it happens is that each channel is really just the center frequency of a 22 MHz wide channel.

That means only channels one, six, and eleven are far enough apart not to overlap. As you can see in the picture above, devices on channels one and two would interfere with each other and share a lot of space on the radio spectrum. That makes it challenging to pack too many devices on to the same network, primarily because most IoT Wi-Fi devices operate on 2.

The 5 GHz offering gives faster speeds, more channels, and more room for devices to transmit than 2. Over shorter distances, the broader channels of 5 GHz can allow for faster data transfers, but not all devices support the frequency. Modern routers will typically offer both types to provide the most spectrum for congested Wi-Fi networks, and modern smartphones and laptops will likely support 5 GHz networks. That makes it equally likely that a device belonging to a target might be connected to the 5 GHz or 2.

To get started hacking 5 GHz networks, we'll need a network adapter with the proper chipset. Once we have the drivers installed, hackers will find that many standard Wi-Fi hacking tools work perfectly well against 5 GHz targets. Kismet , Wireshark , the Aircrack suite , and Wifite2 are all updated to take advantage of the ability to target 5 GHz networks. That means hackers who can't access 5 GHz channels are missing out on half of the fun, which may become an issue with devices that can transition between both types of networks.

To get started with hacking 5 GHz networks, you'll need a wireless network adapter that supports 5 GHz and preferably 2. If you want to extend your range, you can also look into a long-range directional antenna like the Simple Wi-Fi dual-band antenna , which can pick up both 2. To enable monitor mode you will need to type the following command into your terminal session:. Now that monitor mode is enabled we can perform some further tests to make sure that we can capture packets.

We will be using the Airodump-ng feature to capture raw packets frames. To begin the packet capture process you will need to enter the following into your terminal session:.

After issuing that command you should see that your WiFi adapter is finding beacons from the various wireless networks around you. If your WiFi adapter is not finding anything then you may need to reset the WiFi adapter. You can do this by exiting your current terminal session and opening a new one and typing:. Any help? My host is Ubuntu Linux. But that USB wifi adapter price is high.

Well, the choice dwells on the ability of a wireless card to support monitor mode, which is very uncommon with many wireless network adapters. Since not all adapters whose drivers can capture wireless transmissions while posting them where needed, the article will guide you through the Best Wireless Network Adapter for WiFi Hacking in For beginners, the guide will essentially center on Kali Linux and a round-up on a few adapters out there including:. As of November , this is my new favorite antenna.

It fully supports monitor mode and is able to do packet injection. If you are looking for something portable, this is your choice. So, before you buy or ship the adapter make sure to crosscheck the version or inquire from your seller. Apparently, the adapter is well supported by a number of Linux OS, and there is no big need of installing drivers when using it on Kali.

To sniff packets use Aircrack-ng suite and do not forget to maintain the adapter in monitor mode. Note that it will also display the driver details. With a speed of mbps and a frequency of 2. This adapter employs the use of the Ralink RT chipset and due to its plug and play functionality; it is effective on Kali Linux. Usually, it is compatible with several brands of routers including PS: fine research also suggests that Ralink RTN, which was tested with Kali, is also part of the list supporting managed and monitor modes.

Often, the maximum wireless connection speed of the adapter wavers at mbps for both frequencies. Have a look at its picture to have a physical capture of the adapter. Packet injection in Kali Linux was announced in April and users should refer to technical forums on how to install its drivers.

To attain the maximum connection of Mbps you will probably require a 3.
