[quote author=“deathstar”]not sure if it’s legal to discuss this ... how easy it is to crack WEP? Is there any tools that can do this?

Legal to discuss, sure. Just don’t discuss your plot to take over the free world. :twisted:

WEP is not secure. Still, using 128 or 156 bit encryption (if your hardware supports it) and changing passwords regularly you’re fairly secure, particularly as a home user.

WEP is dead. From WiFi-Planet.com:

802.11i is the long-awaited security standard for Wi-Fi networks that upgrades the former “official” wireless security standard, the much-maligned wired equivalent privacy (WEP). WEP was found to be easy to crack by those with the right tools and enough patience—and so hard to implement that most people don’t bother turning on the security at all.

WPA is the new kid on the block and most of the current crop of hardware supports it. The finalized 802.11/i standard, however, also includes AES encryption. From the same article (bolding mine):

Official 802.11i has all the abilities of WPA and adds the requirement to use Advanced Encryption Standard (AES) for encryption of data. AES provides enough security to meet the needs for the Federal Information Processing Standard (FIPS) 140-2 specification, which is required by many government agencies. The downside is that AES support may require new hardware for many existing WLANs, as it needs a dedicated chip to handle the encryption and decryption.

The WiFi Alliance won’t begin certifying compliance until later this year. Nevertheless most manufacturers have been delivering products based on the evolving standard. The question in my mind, at least, is will my TR upgrade?

Some of us may be able to get by with a firmware download from the manufacturer, some may be able to send it in or exchange for new hardware and some of us are…
