This tutorial explains how easy it is to bypass a wep encryption of a wifi with no connected clients. WEP encryption is very easy to get bypassed and it doesn't matter whether a client is connected to the access point or not. In this video we are going to show the fragmentation attack, however it might be possible that it doesn't work on some routers. But if not this one, then any other (like chopchop) will surely work, which I will demonstrate in coming videos. Hence you are nowhere safe with WEP.
