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 computers, and every solution I've looked up has not worked. I've also checked with the ISP and it isn't on their end. Any help will be appreciated. Here is a shortened version of the ping test I did:Reply from 8.8.8.8: bytes=32 time=21ms TTL=54Reply from 8.8.8.8: bytes=32 time=15ms TTL=54Reply from 8.8.8.8: bytes=32 time=14ms TTL=54Reply from 8.8.8.8: bytes=32 time=13ms TTL=54Reply from 8.8.8.8: bytes=32 time=14ms TTL=54Reply from 8.8.8.8: bytes=32 time=2441ms TTL=54Reply from 8.8.8.8: bytes=32 time=42ms TTL=54Reply from 8.8.8.8: bytes=32 time=14ms TTL=54Reply from 8.8.8.8: bytes=32 time=17ms TTL=54Reply from 8.8.8.8: bytes=32 time=14ms TTL=54Reply from 8.8.8.8: bytes=32 time=1961ms TTL=54Reply from 8.8.8.8: bytes=32 time=17ms TTL=54Reply from 8.8.8.8: bytes=32 time=13ms TTL=54Reply from 8.8.8.8: bytes=32 time=14ms TTL=54Reply from 8.8.8.8: bytes=32 time=17ms TTL=54Reply from 8.8.8.8: bytes=32 time=15ms TTL=54Ping statistics for 8.8.8.8:Packets: Sent = 1171, Received = 1171, Lost = 0 (0% loss),Approximate round trip times in milli-seconds:Minimum = 11ms, Maximum = 2441ms, Average = 20ms

In the absence of any useful information, the usual boilerplate questions to eliminate some of the more common issues that crop up here.What firmware version do you have on the device? A number is more useful than "the latest". There may be newer versions, or "hot fixes", that do not show up if you check for new firmware with an app or in the browser interface.If there is one it might also help if you told people the make and model number of the modem/gateway/ONT that connects this router to the Internet. Is it, by any chance, also a router, with a set of LAN ports on the back?I ask because a lot of people turn up here trying to put a router behind a modem that is also a router. That can complicate troubleshooting.

Just put the router in bridge mode and ran a ping test, and I’m still getting lag spikes.

With such sparse information from you, it is difficult for anyone to begin to diagnose what might be going on. 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?
