No internet connection when trying to set up new AX12 Router

A couple things. 

1. the cm1200 has 4 ethernet ports. But for most ISP's, you can only connect 1 device to it because they only allow 1 public ip address. 

2. lets get the cm1200 working and the rax120 connected to it with hardwired connection. Then we'll work on the wireless. 1 problem at a time. (you can always check if the wifi on/off button got it, push and hold it for 2 seconds)

3. Try this: 

power off the modem and the router. unplug everything from both, even coax from modem. wait 2 minutes. 

connect coax back to modem and power it on. wait several minutes for it to fully boot. 

plug port 1 from modem into wan port on router. turn the router on. 

give the router several minute to fully boot. 

connect a pc/laptop to one of the lan ports on the router. attempt setup on it.
