I have an Intel Mac and a wireless connection to the net. I have an Airport Extreme Base Station 54 mbps and a Netgear ADSL modem dm602. I shared the connection with my old neighbour and we had an address and password, which I think allowed only us to access the network. For some reason my network address has vanished from the pop up window under the Internet signal sign (top right of screen). I can see two of my new neighbours home hub addresses, which are padlocked, but my connection seems to be called something like apple gaje33 but there is no padlock. I can access the web on this. Can someone please tell me what has happened and what I should do about it please? Where has my network name gone and why has this new address appeared? is it ok to have no padlock and what should I do (step by step no techy talk please) Can someone else be accessing this connection. I am scared of having a go as Ill probably do it wrong and lose my Internet connection)- can someone help please. Thanks.
