networking through 2 routers

i have 2 routers. one is a modem/wired router by netcomm and the other is a Dlink wireless router. i have wired one connected to the wireless which gives the wireless computers internet but since i have connected my computer to the wireless network i havn’t been able to network to the computers connected to the netcomm router. does anybody know how i can connect the computers together through the 2 routers?
