MR60 Lag Spikes
I have a Nighthawk MR60 Mesh system, and for the past couple of months now I have been getting lag spikes that appear for around 5 seconds and then go away. It happens constantly on different compute...

The "modem" is, as you say, a gateway. So it is a modem and router combined,
Two routers on your network can cause headaches. For example, you can end up with local problems with address on your network. Among other things, the other router can misdirect addresses that the Netgear router usually handles, such as routerlogin.net or the usual default IP address for a router, 192.168.1.1.
This explains some of the other drawbacks.
What is Double NAT? | Answer | NETGEAR Support
Unless you have specific reasons for using two routers – to create two separate networks for example – it is often easier to use just one router and then to set up the second router as a wifi access point (AP) with a wired connection to the main router. Netgear advises this, as does just about every site you will visit.
My NETGEAR or Orbi router is connected to an ISP gateway or another router, and it's causing double NAT problems. How do I fix them? - NETGEAR Support
It may be possible to put the modem/router into modem only (bridge) mode and then to use the second device as the router. Sometimes it is easier to put the second router into AP mode. But that has its own drawbacks:

Even that sentence doesn't really tell us what you did.
The router? Is that the gateway?
Did you go through all the usual restart things when you changed the network?
You may need a genuine network aficionado to help you out, but they may well ask for more details about what is on your network.
You have obviously spent some time doing all manner if things t try to see what might cause this. Here we are working from a blank sheet.
For a start, any claims that your ISP has made need confirming. They are never the most reliable sources of information. "It s all right at your end" is not much help. They don't tell us if there are any line issues into your cable modem/router.
Have you look at the Netgear router's logs for any signs of strange activity?
- Phillips60Mar 24, 2024AspirantSorry, I bridged the gateway and restarted it and my computer and I still got ping spikes, up to 2800 ms. Also, I don’t think it’s the isp because when I had my laptop connected via Ethernet to it the problem wasn’t there, but it was there when the same laptop was connected to the Netgear. After I restarted both I logged into the router setup to check the logs then ran the ping test, and nothing looked out of the ordinary except for this:

But searching it up seems to indicate that it’s a red herring.
