Question: Linda has been assigned the job of connecting 5-computers to a network. The room holding 5-computers has 3-network ports that connect to a hub in an electrical closet down the hallway. Linda decides to install a second hub in the room. The new hub has four network ports. She uses a crossover cable to connect one of the four ports on the hub to a wall port. Now she has five ports available (two wall ports and three hub ports). While installing and configuring the NICs in the five computers, she discovers that the PCs connected to the two wall ports work fine, but the three connected to the hub refuse to communicate with the network. What could be wrong and what should she try next?
