I am a novice to Cisco. I am trying to set up an Aironet 1140 series access point. It works fine if I do not put any security on it. I am trying to put WEP on it. No matter which encryption I put on (40 or 126 bit) none of the laptops or RF guns can associate with it. I know it is asking for HEX and the laptops and RF guns are asking for ascii characters. Is there something I can do? I need some security on this.
