R8000P with ISP Static IP

Greetings!

I am struggling to get my router working on my home network. I am trying to connect to an Arris modem and my ISP has given me a static IP.

I currently use an old Apple Airport Extreme, which works, but it is slower than my internet speed is capable of, so I choose to upgrade to an R8000P.

Unfortunately, I am not savvy with internet protocol, so I enlisted Netgear's help desk, got a ticket and spent over an hour on the phone trying to get connected to teh internet. The router works fine on the local network, but fails to get internet.

We've tried connecting a computer directly to the modem to confirm the modem's IP address. That worked for the computer. The setup for Static IP on the router matches the setup used on the computer (to the best of my understanding), but the router refuses to connect to the internet.

The help desk appears stumped, so I am hoping that someone here might point me in the right direction.

Thanks!

Looks like it is solved.

I reset the router and let the "genie" do the setup. It saw the static IP and prompted me for the IP, subnet, gateway, and DNS. Once entered it sprang to life.

Thanks to everyone who chimed it!!!

   Has your "an Arris modem" a model number?

   Which is?

   Ok. Did they tell you that you need to configure your router with
static IP parameters, or can you still use DHCP for the router's
WAN/Internet interface?

How is _it_ configured?

   Did you contact your (unspecified) ISP? Cable-TV providers can be
fussy about (or fearful of) different (or multiple) devices connecting
to your cable. You may need to provide a MAC address to your ISP.

   The non-psychics in your audience can't see any of that "setup".

> [...] but the router refuses to connect to the internet.

   Or the ISP refuses to allow your new router to connect to its
network.

  Thank you for the reply.
  
  The R8000P firmare is the latest. I don't have the number before me as the unit is disconnected at the moment, but I did check that it was.
  
  The ISP provider is Spectum Communications (formerly Brighthouse) and the modem is Arris model DG1670.
  
  Ye, I did inform Netgear help-desk that I was using a static IP and they guided me to the setup, which seems pretty straight forward.
  
  Withou spilling the beans on the specific numbers, my provider gave me:
  
  IP address 2x.xxx.xxx.xx4 <== my static IP
  Subnet Mask 255.xxx.xxx.xx2
  Default Gateway 2x.xxx.xxx.xx3 <== The Apple calls this the router address and I believe it is the IP address of teh Arris modem.
  DNS Severs 75.xxx.xxx.1
  75.xxx.xxx.2
  The router mode is DHP & NAT not sure about the modem settings.
  
  I will contact my ISP and see if they need something that I don't know or have suggestions (i.e., MAC address of the new router). This may take a day or two as we are fighting fires at work and long hours make getting my router working difficult.
  
  Thanks again.

    One of these?

    That looks like a modem/router. See all those LAN ports on the back?
    
    Two routers on your network can cause headaches. For example, you can end up with local address problems. Among other things, the other router can misdirect addresses that the Netgear router usually handles, such as routerlogin.net or the usual IP address for a router, 192.168.1.1.
    
    This explains some of the other drawbacks.

    To avoid that, you have two quick options. Put the DG1670 into "bridge" (modem only) mode, or use the R8000P as a wireless access point.
    
    I would sort that out before worrying about the settings for the internet service.

  I should add, can you suggest what questions I should be asking my ISP?
  
  I know that understanding the questions is at least 50% of the battle. If I know what I should be asking I can at least try researching them to better understand.
  
  Thanks everyone!
