UTP Cable.                                                                      
The UTP cable is the unshielded twisted-pair cable,                             
like telephone cable, that connects the adapter to                              
the wall socket.                                                                
                                                                                
LAN Problems.                                                                   
Problems on the LAN itself can also prevent you from                            
communicating with it, and these problems can arise for many                    
reasons.  For example, devices on the LAN with which you are                    
trying to communicate, such as servers, routers, bridges,                       
and gateways, may not be active or may not recognize your                       
address and allow you access.  Again, most LAN problems are                     
best resolved with the help of your network administrator.
