Wi-Fi, or IEEE 802.11, is the standard for wireless LANs, or WLANs. The abbreviation Wi-Fi stands for Wireless Fidelity, and resembles the Hi-Fi acronym. It represents a whole collection of protocols within the same family of Ethernet and Token Ring.
It is specified by various IEEE 802.11 specifications.
IEEE 802.11 sends network packets from the sending host to one (Unicast) or more (Multicast/Broadcast) receiving hosts.
The 802.11 protocols specify a wireless shared network, which means that the maximum bandwidth is only available to one user at a time.
See the CaptureSetup/WLAN page for instructions how to capture from WLAN's (including monitor mode), and see the CaptureSetup page for general information on capturing on WLAN's and other media.
802.11 Standards
The basic 802.11 standards are:
802.11 (2MBit/s 2.4GHz) First generation of WLAN equipment; allows 1 and 2 Mbps.
802.11b (11MBit/s 2.4GHz) Second generation of WLAN equipment, and the first generation to receive widespread use; allows 1, 2, 5.5 and 11 Mbps.
802.11a (54MBit/s 5GHz)
802.11g (54MBit/s 2.4GHz)
802.11n Enhancements for Higher Throughput
Some additional 802.11 standards are:
802.11i (Security WPA1 and WPA2) No change to data rate. Improvement in security.
802.11h (Spectrum and Transmit Power Management)
802.11e (Quality of service, packet busting)
802.11d International (country-to-country) roaming extensions
802.11f Inter-Access Point Protocol (IAPP)

802.11 vs. 'fake Ethernet' captures
When capturing with Wireshark (or other tools using libpcap/WinPcap, such as TcpDump / WinDump) there are two ways in which 802.11 can be supplied by the system and stored in a capture file:
'real' 802.11: the hardware/driver provides the actual protocol data that travels over the air, complete with 802.11 headers. (There are variants of this in which 'radio information' such as signal strength can be provided as well.)
'fake' Ethernet: the hardware/driver translates the 802.11 headers into Ethernet headers so that the whole packet looks like a normal Ethernet packet. If the hardware/driver is doing this, all 802.11-specific management and control frames are usually discarded, as there's no equivalent to them in Ethernet (although some drivers might use a non-standard way of making them look like Ethernet packets, such as using a special Ethernet packet type).
Detailed information about how to capture 802.11 traffic can be found at the CaptureSetup/WLAN page.
Protocol dependencies
802.11 is the lowest software layer, so it only depends on hardware.
Example traffic
One ICMP Ping Request and response session from Station(STA1 to station(STA2) via Access point(AP) ICMP ECHO request
ICMP Echo request (802.11 data packet with source STA1, Destination STA2, To DS bit set) This packet is transmitted from STA1 and received by AP
ACK(802.11 control packet, dest STA1) This packet is transmitted by AP and recieved by STA1
ICMP Echo request (802.11 data packet with source STA1, Destination STA2, From DS bit set) This packet is transmitted by AP and received by STA2.
ACK(802.11 control packet Dest AP) This packet is sent to AP by STA2 to acknowledge reciept of the Echo request packet.
ICMP ECHO Response
ICMP Echo response(802.11 data packet with source STA2, Destination STA1, To DS bit set) This packet is transmitted from STA2 and received by AP
ACK(802.11 control packet, dest STA2) This packet is transmitted by AP and recieved by STA2
ICMP Echo response (802.11 data packet with source STA2, Destination STA1, From DS bit set) This packet is transmitted by AP and received by STA1.
ACK (802.11 control packet Dest AP) This packet is sent to AP by STA1 to acknowledge reciept of the Echo response packet.

Wireshark
The 802.11 dissector is fully functional. It supports WEP and WPA/WPA2 decryption (see HowToDecrypt802.11 for details) and 802.11n.
Capturing 802.11 traffic can be tricky, see CaptureSetup page for instructions how to capture from WLAN's (including monitor mode) and other media.
Preference Settings
802.11 is a complex protocol and Wireshark has a variety of 802.11-related preferences as a result.
The reassembly and retransmission settings can affect the way that higher-layer information is dissected and displayed. The FCS and Protection bit settings can affect how frames are decrypted. For detailed information about the decryption settings, see HowToDecrypt802.11.
You can also add 802.11-specific information to the packet list.

Newer versions of libpcap support raw 802.11 headers via the 'wlan' link type. Older versions must use 'ether' or 'link' via fake Ethernet headers, and might not support 802.11 capture at all.

An internet connection has become a basic necessity in our modern lives. Wireless hotspots (commonly known as Wi-Fi) can be found everywhere! If you have a PC with a, then you must have seen many networks around you.
Sadly, most of these networks are secured with a network security key. Have you ever wanted to use one of these networks? You must have desperately wanted to check your mail when you shifted to your new house. The hardest time in your life is when your internet connection is down. Cracking those Wi-Fi passwords is your answer to temporary internet access.
This is a comprehensive guide which will teach even complete beginners how to crack WEP encrypted networks, easily. If it's WPA2-PSK passwords you need to crack, you can use. Table of Contents • How are wireless networks secured? • What you'll need • Setting up CommView for Wi-Fi • Selecting the target network and capturing packets • Waiting. • Now the interesting part.
• Are you a visual learner? Step 1: How Are Wireless Networks Secured? In a secured wireless connection, internet data is sent in the form of encrypted packets. These packets are encrypted with network security keys. If you somehow manage to get hold of the key for a particular wireless network you virtually have access to the wireless internet connection.
Broadly speaking, there are. WEP (Wired Equivalent Privacy) This is the most basic form of encryption. This has become an unsafe option as it is vulnerable and can be cracked with relative ease. Although this is the case many people still use this encryption. WPA (Wi-Fi Protected Access) This is the more secure alternative. Efficient cracking of the passphrase of such a network requires the use of a wordlist with the common passwords.
In other words you use the old-fashioned method of trial and error to gain access. Variations include WPA-2 which is the most secure encryption alternative till date. Although this can also be cracked using a wordlist if the password is common, this is virtually uncrackable with a strong password. That is, unless the WPA PIN is still enabled (as is the default on many routers). Hacking WEP passwords is relatively fast, so we'll focus on how to crack them for this guide.
If the only networks around you use WPA passwords, you'll want to follow this guide on instead. Step 2: What You'll Need • A compatible wireless adapter: This is by far the biggest requirement.The wireless card of your computer has to be compatible with the software CommVIew. This ensures that the wireless card can go into monitor mode which is essential for capturing packets. Altus flutes serial number lookup. To check if your wireless card is compatible • CommView for Wi-Fi: This software will be used to capture the packets from the desired network adapter. To download the software from their website.
•: After capturing the packets this software does the actual cracking. To download the software from their website. • A little patience is vital. Step 3: Setting Up CommView for Wi-Fi • Download the zip file of CommView for Wi-Fi from the website. Extract the file and run setup.exe to install CommView for Wi-Fi. When CommView opens for the first time it has a driver installation guide.
Follow the prompts to install the driver for your wireless card. Torrent Poison Greatest Hits. • Run CommView for Wi-Fi. • Click the play icon on the top left of the application window. Start scanning for wireless networks.

Step 4: Selecting the Target Network and Capturing Packets A few things to keep in mind before choosing the target wireless network: • This tutorial is only for WEP encrypted networks, so make sure you select a network with WEP next to its name. If you need to crack a WPA encrypted network, follow instead. • Choose a network with the highest signal. • Each network will have its details in the right column. • Make sure the WEP network you are choosing has the lowest dB (decibel) value. Once you have chosen your target network, select it and click Capture to start capturing packets from the desired channel. Now you might notice that packets are being captured from all the networks in the particular channel.
