Tips & Warnings

• This same procedure can also be used to connect a PC and a laptop or two laptops.
• Only use a crossover LAN wire or an ethernet crossover cable to connect two PCs. Any other type of cable is unable to handle the amount of data that will cross between the two systems and will result in serious damage to the computers' motherboards.
