@Donorob -- Update: I called Shaw and they said the modem only comes with 1 IP assigned to it.

Correct. An "unbridged" cable-modem "consumes" that "public" IP-address, as supplied by Shaw's DHCP-server.

> They added another (for free)

Shaw allows each customer to have two IP-addresses. One IP-address is consumed by the "unbridged" cable-modem, and the other IP-address can be "passed-through" to the WAN port on your Nighthawk device.

UPDATE: you need the second IP-address ONLY if you are configuring the Nighthawk as a router. If you configure the Nighthawk as an Access Point, it just extends your private network.  The following comments assume that you are using the Nighthawk as a router.

> I set Shaw modem to bridge to the nighthawk. 

Did you "bridge" the entire modem, or just designate one of the cable-modem's Ethernet ports to receive the 2nd IP-address?

The other Ethernet port(s) on your cable-modem, and any of your wireless devices, will use "private" IP-addresses, as supplied by the cable-modem.

If you have the BlueCurve cable-modem, those "private" IP-addresses will start with "10.0.0.", while the other cable-modems will provide IP-addresses starting with "192.168.". What do you see?

Note that your Nighthawk router also hands-out "private" IP-addresses. Be sure to configure it to hand-out IP-addresses starting with "192.168.123.", if you do NOT have the BlueCurve cable-modem. Actually, while "123" will work, you can pick any three-digit number, to avoid any "collisions" with the "192.168.yyy." IP-addresses that your modem will be handing-out.

>  I can search for things on google, results come up, but can’t go to any sites.  I’m thinking DNS server issues?

Strange. Your computer has connected to a DNS-server, to find the IP-address of Google's web-server, and has connected to it, and you have received the search-results from Google. Equally, your computer should find the IP-address for any host-name listed in the search-results, and should connect to it.  So, it is NOT "DNS-server" issues.

On each computer, use the command-line utiltity: IPCONFIG /ALL

to see output like:

  IPv4 Address. . . . : 192.168.0.10
  Lease Obtained. . . : January-01-21 12:54:41 AM
  Lease Expires . . . : January-03-21 07:16:05 AM
  Default Gateway . . : 192.168.0.1
  DHCP Server . . . . : 192.168.0.1
  DNS Servers . . . . : 192.168.0.1

It shows the IP-address of the DNS-server(s), and the IP-address of either your Nighthawk or your cable-modem.

@Gtown122 -- I will be getting a ethernet hub next week 

Instead, purchase a "switch", not a "hub", because a "hub" will broadcast every incoming packet out to every connected device, and the network-adapter in each device will just "drop" packets that it does not want to handle, while a "switch" will distribute each packet only to one device -- the device that "wants" the packet.

@Gtown122 -- I was a 300 subscriber, but they wanted to charge me $10/month just for the modem. I mentioned that I should be eligible for a replacement XB6 instead of another Hitron, but they only offered me 7 months of modem credit.

I am an "Internet 300" subscriber with the Hitron cable-modem, with about 6 months left on my "grandfathered" two-year Value Plan. My monthly invoice shows a "rental" charge for the cable-modem, AND an offsetting "credit" for the same amount, i.e., a "net" of $0/month for the Hitron. Do you have SEVEN months left on your two-year Value Plan? I suppose that when I renew, my current "Internet 300" plan will not be available, and I will get what is marketed as the "Fibre+ 300" service -- still using the Hitron, but with an option to switch to the BlueCurve cable-modem, at no extra cost to me.

I bridged the entire Shaw modem. (Well Shaw did when I was on the phone with them.)

I am getting a 50.xx.xx.xx from the other port of the Shaw modem.

default gateway and dns are ipv6 addresses

default gate has an ipv6 and another 50.xx.xx.xx address

@Donorob -- I am getting a 50.xx.xx.xx from the other port of the Shaw modem.

> default gate has an ipv6 and another 50.xx.xx.xx address

Yes, Shaw's infrastructure uses "IPv4" addresses, and "50.xx.yy.zz" is within a range assigned to Shaw.

Both of those "50." IP-addresses are what you should be getting -- one IP-address for your computer, and one IP-address for the Shaw router in your city/town.

[Donorob]

Update: Shaw tech came in, was stumped by the issue. Replaced the modem and everything is working now.

He mentioned he tries to stay away from bridge mode as often as he can 

[DGittins]

I'd like to do the same thing. 

[Donorob]

Mine was a hardwire issue, besides that it’s easy to setup.

Good luck, it’s well worth it. I’ve upgrade since using an edge router and using a vlan

@Donorob -- ‎2020-12-29 05:13 PM -- I understand I should use a LAN port on the Nighthawk modem and not the WAN.

Quite a while ago, but I think that you should be connecting the run from the cable-modem (or your switch)  to the WAN port on the NightHawk.

Hint: power-off your cable-modem, and then do a power-on. When it is "bridged", it counts the number of connected devices, and limits it to just two active devices. If you temporarily connect a third device, even if you intend to just temporarily use the third device to "trouble-shoot", you might exceed the "two-device" limit, and thus won't get Internet access for that third device.
