Replaced Nighthawk with Nighthawk. Now devices can't see each other.
I recently replaced an older Nighthawk router with a new R7800. I have updated the firmware and performed a factory reset. I was hoping that it would be relatively plug-and-play to remove the old one and install the new one.
My issue is that none of the PCs on the network, whether they are wired or Wi-Fi, can see the wired network printer. The printer does show up on the list of connected devices when I go to the router (routerlogin.net), but on any PC, it shows as offline and I cannot ping the printer.
My setup is modem->Nighthawk->network switch->printer
None of the PCs are connected to the same network switch as the printer, could that have something to do with it?
Any assistance is greatly appreciated.
Thank you all for the help. I finally got it all working. It appears it was a combination of things. I did have some static IPs that needed changed. I also re-booted everything again, in the right order. (Not sure if this helped, but maybe the second time was the charm.)
For those of you who took the time to offer constructive help, thank you so much.

You can't just swap out one device for another. Your whole network needs to adapt, including the modem.
Be sure to restart your network in this sequence:
- Turn off and unplug modem.
- Turn off router and computers.
- Plug in and turn on modem. Wait 2 minutes for it to connect.
- Turn on the router and wait 2 minutes for it connect.
- Turn on computers and rest of network.
If that doesn't work, you may have to reset the and reconfigure that modem. It is designed to work in partnership with the router.
I don't understand this bit:

You are running two separate networks?
Thank you for your help. I have just now powered-down and powered-up everything in the sequence suggested above. Unfortunately, I still don't have access to other devices on the network. I have a Netgear NAS that was mapped to network drives. I have a network printer. All of these things were accessible from my PC before I replaced my old Nighthawk with a new Nighthawk. Now, they are not accessible from the PC.
If that doesn't work, you may have to reset the and reconfigure that modem. It is designed to work in partnership with the router.
I'm not sure that I understand how a change in the router would make it so that the settings of the modem need to be changed in order for my network printer to be seen on the network. If this is the case, does that mean I need to contact my ISP?

I have three NETWORK SWITCHES that are downstream of the router. I'm just grasping at straws here by mentioning that my PC isn't on the same NETWORK SWITCH as the printer. However, it is on the same switch as the NAS, so that doesn't explain my inability to connect to the network drives.

Did your (unspecified) "an older Nighthawk router" have a model
number? Did you have address reservations (or other non-default
settings) configured on it?> [...] on any PC, it shows as offline and I cannot ping the printer.
"cannot" is not a useful problem description. It does not say what
you did. It does not say what happened when you did it. As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations. Copy+paste is your friend.What are the IP addresses of these gizmos?
> My setup is modem->Nighthawk->network switch->printer
What, exactly, is your (unspecified) "network switch"? Where's your
"any PC" in that picture?
> None of the PCs are connected to the same network switch as the
> printer, could that have something to do with it?That would depend on whether your "network switch" is really a
network switch."the same network switch"? How many are there? What, exactly, is
connected to what, exactly? (Hint: If a device has different types of
Ethernet ports, then "connected to device" is not enough detail.)

could easily have been interchangeable. Apparently, there's some
difference between their configurations.

"NETWORK SWITCHES" is not a much more detailed description than
"network switch".If all your devices are on the same LAN IP address subnet, then your
(unspecified) "NETWORK SWITCHES" shouldn't matter. But "ping" should
work from any device on that subnet to any other.
different MAC address, it's now untrusted by Windows and is treated as a new 'public' network. Same applies if you swap in a new wireless card in a desktop or laptop.
You need to switch it to a Public Network AND turn on Network Discovery and Filesharing on for it, on every Windows device you have connected.

Do you mean switch it to a private network?
As you said hasn't Windows already taken it into its head to do that?
My network is Private.
The OP says he swapped routers, that's a new MAC address so it's treated by Windows as a new public network, even via ethernet.
(Even if it's the same make and model is swapped in, same SSID's and passwords for Wifi, Windows will still see it as a new public network.)
In order to see devices and shares again, it needs to be set to a private network and network discovery and file and print sharing turned on. These are specific to eash registered network. Filesharing and network discovery can be turned on for public networks I believe, but that's not secure and not recommended.
I don't recall if Windows has an option to treat all networks as private, but if there is, that would not be recommended, especially for wireless laptops.
Sorry,

Thanks. That's what I thought. Hence my question.
Good to have the Mac address thrown into the mix. That may also influence the modem<>router link and need to reboot everything in the right order..
