The flaws in WEP make it susceptible to various statistical cracking techniques. WEP uses RC4 for encryption, and RC4 requires that the initialization vectors (IVs) be random. The implementation of RC4 in WEP repeats that IV about every 6,000 frames. If we can capture enough of the IVs, we can decipher the key!
WEP stands for Wired Equivalent Privacy, a Wi-Fi wireless network security standard. A WEP key is a security passcode for Wi-Fi devices. WEP keys enable devices on a local network to exchange encrypted (mathematically encoded) messages with each other while hiding the contents of the messages from easy viewing by outsiders.
How WEP Keys Work
Network administrators choose which WEP keys to use on a network. As part of the process of enabling WEP security, matching keys must be set on routers as well as each client device for them to communicate with each other over the Wi-Fi connection.
WEP keys are a sequence of hexadecimal values taken from the numbers 0 through 9 and the letters A through F. Some examples of WEP keys are:
- 1A648C9FE2
- 99D767BAC38EA23B0C0176D152
The required length of a WEP key depends on which version of the WEP standard the network runs:

- 40- or 64-bit WEP: 10 digit key
- 104- or 128-bit WEP: 26 digit key
- 256-bit WEP: 58 digit key
To assist administrators in creating correct WEP keys, some brands of wireless network equipment automatically generate WEP keys from regular text (sometimes called a passphrase). Additionally, some public web sites offer automatic WEP key generators that generate random key values that are difficult for outsiders to guess.
Why WEP was Once Essential for Wireless Networks
As the name suggests, WEP technology was created to protect Wi-Fi networks up to the equivalent levels that Ethernet networks had been protected. The security of wireless connections was significantly less than that of wired Ethernet networks when Wi-Fi networking first became popular.
Network sniffer programs allowed anyone with a bit of technical know-how to drive through residential neighborhoods and tap into active Wi-Fi networks from the street. This became known as wardriving. Without WEP enabled, sniffers could capture and view passwords and other personal data unprotected households sent over their networks. Their internet connections could also be reached and used without permission.
WEP was at one time the only widely-supported standard for protecting home Wi-Fi networks against sniffer attacks.
Why WEP Keys are Obsolete Today
Industry researchers discovered and made public major flaws in the design of WEP technology. With the right tools (such as programs built to exploit these technical flaws), a person could break into most WEP protected networks within a matter of minutes and perform the same kind of sniffing attacks as on an unprotected network.
Jun 04, 2018 Windows 10 Driver for Radeon x300/x550/x1050 series? Question asked by terry1337 on Jul 6, 2016. No, there are no drivers available from AMD for these legacy products. You will need to rely on Windows Update to obtain limited support for these GPU's. 1 person found this helpful.
Feb 07, 2018 Just upgraded a media server to windows 10, it had a OLD X300 graphics card that works fine, however for the life of me I cant get it to install. Have googled this but none of the solutions seem to work (Ive tried to add legacy hardware, manually install VISTA drivers to name but a few solutions).
Newer and more advanced wireless key systems including WPA and WPA2 were added to Wi-Fi routers and other equipment to replace WEP. Snooker games download for windows 7. Although many Wi-Fi devices still offer it as an option, WEP has long been considered obsolete and should be used on wireless networks only as a last resort.
