Get a crossover network cable. This is a type of Ethernet cable used to connect two computers together. If either machine is older, you must use a crossover cable. Regular ethernet cables will not work with older machines. There is no physical difference between these two cables. To be safe, ask a store employee to find the crossover cable for you.

Connect the two ends of the cable to the network ports of the two laptops. The network port is where you connect the Ethernet cable to your computer. The cable will make a clicking sound when it is successfully connected to the network port.

Note that some newer laptops do not have network ports. Some laptop manufacturers have decided to remove them to make laptops lighter or thinner. In that case, move on to the next method for working with wireless connections.
