Can 2 computers have the same i.p. address?
no there will be a ip conflict, between the two computers, the router should automatically assign different ip to each one, unless you have the computer set to use only a certian one… which the best thing to do you be optain ip address automatically, if you are having a ip conflict feel free to mail me what brand router you have and i will help you set it up along with getting the computers set up.
