In my company I have given access for 10 laptop out of 20 to use internet by wireless. For security purpose I have configured WAP Personal and Encryption TKIP. So the other laptop users do not know the security key. But yesterday I have found that more than 10 laptops accessing internet via wireless. There was no problem with security of wireless access point. It is secures with password. For that reason I checked into the laptop. It was running Window Vista Business. When I opened wireless adapter connection --> Properties> Security Tab, there was a check box " Show characters" and it was checked and due to this Network security key is visible. Donít know how? Anyway how can I disable it completely now?
