WEP is not doing what I had envisioned it would do. The WEP keys are supposed to help protect access and manufacturers claim these keys are impractical to crack , but the keys are in fact trivial to copy.
Users can still snoop the network.
Although WEP is supposed to encrypt network traffic so one user cannot eavesdrop on traffic meant for another user, it turns out that if you have a victim in mind, it is still possible to snoop traffic sent to that user. There is no security. If you wanted to control access to your network using these WEP keys, you can forget about it. As you can tell from my notes on Using WEP with Linux , any Linux user would know the key. They claim it is practically impossible to obtain the WEP keys.
