Nighthawk cm1100 and Netgear N600 Wireless Dual Band Router

Question

I bought a new computer (dell desktop) and a new modem (Netgear Nighthawk CM1100).&nbsp; &nbsp;Setting everything up like a "plug and play" like my previous HP desktop.&nbsp; Hooked up modem, plugged it into my Netgear N600 router, plugged into my computer.&nbsp; Nothing.&nbsp; Ok, found out I needed to contact my internet provider to get modem happy, so called Comcast - they did their thing - viola! I had internet - IF I CONNECTED THE MODEM STRAIGHT INTO THE COMPUTER - argh!&nbsp; I needed the router happy and active, but nothing we did worked.&nbsp; They told me to contact Netgear - which I did yesterday morning - after attempting to speak with a representative for nearly 45 minutes and her telling me multiple times to type something into my phone (which will not work at home without the wi-fi router active), she told me she'd call me back in 20 minutes.&nbsp; I told her I couldn't wait a whole lot longer than that because I had to start getting ready for work - after extending my waiting time to another 15 minutes I gave up and got ready for work and still no return phone call.&nbsp; Bottom line - I can't get the router to work with my new modem for some reason - all the lights come on, but the one that looks like a globe remains stubbornly orange.&nbsp; Can anybody help me in simple terms?&nbsp; Thanks

One thing to try.&nbsp;The CM1100 has 2x ethernet ports. but comcast only supports 1 public IP address. Meaning only 1 thing can be connected to it.&nbsp;If you connected your computer and it worked, then try this.&nbsp;disconnect everything from both modem and router.&nbsp;Then power them both off for 2 minutes.&nbsp;reconnect coax to the modem, then power it on and wait 2 minutes.&nbsp;then connect the router to the modem and power the router on.&nbsp;Wait 2 minutes.&nbsp;then try setup/using&nbsp; the router.&nbsp;
