Hi, can anyone help me on this, I've got a buffalo wireless router and it has a "aoss" security system, it works fine on my sisters laptop which has a "aoss" also.However when i connect the macbook of my cousin which does not include the "aoss" security, it will ask for a password in order for it to connect to the network,the instruction said that the mac address of the router should do as a password but when i try to do that it would say invalid password..Can someone help me..thanks
