I’ve owned a NetGear Nighthawk CAX-30 Modem/Router for 6 months. It’s been pretty much trouble free during this time with only occasional need to reboot because of video call freezing. Recently, I began to experience more significant problems with both wired (Smart TV) and wireless (iPad, IPhones) devices losing internet connection or having very long response times even after rebooting the modem/router. The firmware shows current (V1.4.10.8) and speed tests have been consistently good (110+Mbps). Pings have shown poor performance outside of the network with about half of all website pings being 200+ms and/or timing out. The same has been true with pings between wireless devices inside the network. I’m no expert but this suggests to me that there is a problem with the device. Any ideas on how to make a final determination on what is wrong and/or fix it?

nothing obvious if there is or its not in the event logs.

Do you have a screen snip of the cable connections page and event logs?

Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, bad/old/cheap connectors, or corroded connections. Replace them if you do.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.

  Thanks so much for your help! How do I take a pic of the screen you want to see? I only use an iPad - do not have access to a windows device. There are no splitters, etc. This home was completed in late 2018 and there has not been any recent work on any part of this system. It functioned adequately until about 4-6 weeks ago so I can’t think of any events that could possibly have changed that.

    Can you get the iPad to show the screens that show cable connections and event logs?
    
    If so, then I have yet to come across a device that cannot take a picture of the screen.
    
    This?
