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

[Georg Pauwen]

Hello,

I have opened the file. but all devices get a valid DHCP address. Which one does not work in your lab ?

Which version of Packet Tracer are you running ?

Hello,

I have opened your file, saved it (I am using the exact same version as you do, on a Windows 10 machine. You need to wait for a minute for PC0 to get its IP address...

Hello,

what exactly is the problem ? Post your (zipped) Packet Tracer project file here...

Hello,

I hope you all can forgive me for re-opening an oldish thread. But I was also having problems with setting up this scenario and getting it to work as per the Cisco instructions. Simply put, I couldn't get the communication between the wireless router and cable modem to work, despite the interfaces being green, so I was never able to ping the Cisco router from PC0.

I have downloaded and run the revised/fixed PT file which Georg kindly uploaded (see below). 

I am a complete noob to Packet Tracer and there are also significant gaps in my conceptual knowledge re. networking in general, I am finding, so I am trying to rectify these gaps. Sorry, then, if these are dumb questions (!), but based on Georg's uploaded PT file, I would like to ask the following, if I may?

- If you didn't configure the Cisco server statically with the default gateway, how would it ever find the wireless router through the internet?

- Why the Cisco router cannot ping PC0? ("Request timed out")

- Why the Internet port IP address on the wireless router is what it is and why this differs from the LAN IP address of the router?

- Why a straight-thru cable between the wireless router and cable modem doesn't work (despite the scenario instructions from Cisco)

Thanks for your help!
