WEP is weak and remains highly vulnerable and is hardly used. There are simple and readily available tools that can be used to hack WEP encryption. If you have a choice to make between WPA and WPA2, I would suggest you choose WPA2 over its predecessor WPA. Both encryption methods support secure wireless internet networks from unauthorized access but WPA2 offers more protection. WPA2 uses more advanced and stronger encryption keys and support maximum protection for your connection.
