What do you mean by "it didn't like it"? When you connect a computer (any computer) to the router by ethernet cable does it get its correct IP address? If not, the router may not be set to allocate addresses by DHCP. In that case it will be necessary to give the network adapter a fixed IP address in the same range as the router, then go into the router's settings and enable the DHCP server.
