Nighthawk AX2700/CAX30

[DrWarpath]

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?

Take a screenshot on your iPad – Apple Support (UK)

My question was imprecise. I can take a screen shot. It is getting to the screen that displays connections and event logs that I do not know. I think I’ve tried every route using my Nighthawk app and haven’t found the screens showing connections/event logs that I see in other posts - I have assumed those were windows devices. I only have access to an iPad Pro. Can you tell me how to display connections and event logs on that and I will happily provide a screen shot.  Thanks

Netgear wants us all to use its hopeless mobile apps to manage devices. But, as you have discovered, these have their shortcomings and things you cannot get at.

Fortunately, you can also use a browser on the iPad to get at the pages you need.

Connect the iPad to the wifi from the router, then aim your browser at the CAX30. The default address is www.routerlogin.net or you can try the IP address 192.168.1.1

The manual explains where to look for the logs:

Visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware.

Work out how to manage your router with a browser and you may never look back!

Super helpful!  Thanks.  Here are the event logs and to the untrained eye, there appear to be issues. What do you make of it?

[plemans]

Your logs are indicating issues. do you also have the cable connections page? (shows upstream/downstream info). 

If you're on the home page, click on the internet icon

Not much. Cable isn't a common technology in the UK. So it is over to @plemans who knows more than most people about these wrinkles.

At least you now know how to dump the app and take proper control of your modem/router.

[DrWarpath]

Sure do - 6 pages, here they are.  Thanks very much for your help!

[DrWarpath]

#dumptheapp:). thanks again

[DrWarpath]

Again, not knowing what to look for or how to interpret this data handicaps me. But the one thing that appears out of sorts is that Channel 1’s ID is out of sequence at 24 and the power frequency, power and SNR figures appear to be consistent with being in the 24th position.  Is this phenomenon common in other networks?

[plemans]

Your power levels looks pretty good and there isn't errors displayed on there. 

So nothing obvious. You can try checking the "extended power" at the bottom. 

MIght help. 

but the logs are indicating quite a few errors. 

You could have the ISP check the line

[DrWarpath]

I will do both but am wondering if neither of those reveal anything, I guess you’re not seeing anything wrong with my router, right?

So just wanted to thank you again for helping on this. My ISP, Spectrum, performed some tests and found dropped packets and scheduled a service. But a day before the service, they called and informed me that they had several problems in my area and discovered a failed optic connection to be the culprit.  At any rate, we tested again and the packet loss was gone and everything seems to be in order again.  Hope I never need you again but it’s comforting to know you’re here. Best wishes!

Glad you got it resolved!
