An electrical adapter for identifying the connection state to a network is presented. The adapter comprises a first member and a second member. The first member comprises a male end that is substantially similar in shape to a connector plug, and which electrically connects to a wall outlet or a female receptacle. A first female end is disposed at another end of the first member, which includes a hollow cylinder member and a display window. The second member comprises a second female end which comprises a push latch and a mark for identifying a connection state to a network. When the second member is pushed forward, the second female end is engaged with the first female end via the push latch, and a display window displays the mark that identifies the electrical adapter's connection state to the network.
