Nighthawk CM1150

How do I unlock port #2 on the CM1150V  to connect my RedLINK  internet gateway to the internet?  I've hardwired the two devices and an amber light appears on port #2.  I believe the next step is to unlock the port so it will allow the connection.

  • I presume if you connect the other device on WAN port#1 as a test that it will work after the modem is rebooted? 

     

    Hopefully your ISP can allow a 2nd WAN IP to the modem.

    Most ISP's only allow 1 device to be connected to a modem unless you're paying for extra public ip addresses or on a business class line. 

    who's your isp? 

    are you on a business class line or paying extra for more than 1 public ip address?

      Comcast. I contacted them and they told me all 4 ports could be used.  Nest gear says only one at a time.

        Its not that comcast is lying to you but you might have talked to someone who didn't know exactly what was going on for your device or account. 

         

        I have comcast and can confirm they only support 1 device connected at time on a standard line. If you pay for extra public IP addresses or a business class line, then you can connect extra.

    What are you connected to Port#2? When you connect something to port #1 and #2, you need to either reboot the modem from the web page or power off the modem for 30 seconds then back on. If your ISP is allowing a WAN ip address to be assigned to the other ports, then the modem needs to reboot to make the change.

      Tried rebooting, but it didn't solve the problem.  I will call Comcast support again to see if there is something else to try. 

  • I've inquired about this as well and have found that since the 1150v is a modem only, no router, only port 1 is  active.  Not sure if going the Comcast business route or paying for a second IP or static IP pool will get you a second port or if Comcast would know how to enable the second port.

      All that would be needed is to give them the MAC address of the modem and reboot the modem once they give out a 2nd IP address. The modem should see a WAN IP address on the 2nd port after the reboot. You'll need either a wired PC or another router connected to the 2nd port to check the service.
