Packet Tracer Help. What am I Missing. New to Packet Tracer

[Malgandalf01]

I am new to PT and taking the online intro course.

One of the designs they are using at the beginning has three computers connected to a WRT300N which connects to the internet via a cable modem the the cloud then to a server.

I cannot for the life of me get the WRT300n to receive an ip address in the internet port so I cannot ping or get DNS from a workstation to the remote server.

. What silly little thing am I missing?

Yes I am currently a complete noob with PT.

TIA - Mike

I just registered to say thank you. I couldn't wrap my head around this.
