CM1200 DHCP fails after ISP connection established
New CM1200. Power CM on and a connected laptop gets an IP address, allowing browser to access cable modem web adminstration. Connected to ISP (WOW) and they activated from their side. As soon as they...
the mistake a lot of people make is thinking that the cm1200 can have mulitple devices connected to it because it has 4 ports. The only way to connect more than 1 devices to it is if its a business class line or if your isp supports multiple public ip addresses for free (wow doesn't).
So try this.
Power off the cm1200. disconnect everything from it including the coax.
Power off your router. wait a couple minutes.
connect coax back to cm1200. power it on. give it a couple minutes.
Connect port 1 of the cm1200 to the router's wan port.
Power the router on. give it a couple minutes.
attempt setup/using the router.
make sure to plug nothing else into the cm1200. Again, only 1 device can be connected to it. You can run wan port aggregation on it if your router supports it but I haven't heard a good thing about wan port aggregation on consumer routers.
