CAX80 problems
When you buy one of these at this price point, there's a certain expectation that it will just work. set it up once and pretty much forget about it. That has NOT been the case for me as pretty m...
I am on my second Netgear CAX80 modem/router. I have had the same issues as you and I am also in San Diego on COX.
I have all devices in my home connected to the internet on both the 2.4ghz & 5ghz bands. Everything works except for my Samsung S20 Plus. I have gone though ALL the reset options via Samsung, but they say it's the Modem/Router.
Did you find anything to fix this? I am still searching Netgear with no sign of how to contact then directly. Chat redirects in a circle back to here and I cannot find a telephone number to get a technician.
Is the TV the only devices having problems?

I also had this issue with both a Galaxy S10+ and Galaxy S20+ phone and I think its related to the DHCP server on the CAX80. On your phone try using the Phone MAC address instead of a Randomized MAC address. Also try clearing out devices on the CAX80 device list. It seems to only affect WiFi 6 client devices.
My 2 cents
- Thank you for your 2 cents. It helped, kind of... I still need to do a New System Setup everytime. I reboot the modem, but so far Internet works on Samsung Galaxy S20 Plus.
I did this:
Disable MAC Address Randomization in Android 10
Open the Settings app.
Select Network and Internet.
Select WiFi.
Connect to the UT wireless network (UT Open or EDUROAM)
Tap the gear icon next to the current wifi connection.
Select Advanced.
Select Privacy.
Select "Use device MAC"i tried the phone mac address thing too, nothing really fixed the problem with the CAX-80.
the "FIX" in the end was putting the CAX-80 back in the box and soon to be listed on ebay or craigslist.
i am running the c7800 now without a single issue for a month... its big and ugly but it works unlike the CAX-80. i'm on gigblast internet with COX and i get the same speeds with both docsis 3.1 wifi routers, so unless Netgear can find a solution for the much prettier CAX-80, its just junk as far as i'm concerned.
GL to you all!

- I am on my 2nd cax80 as well. I'm still having the same problems. I want to throw this **bleep** out the window. I have the Samsung s20 + as well. I promise you, it's not our phone or cox, ITS NETGEAR. Have you downloaded the nighthawk app for your modem/router? That's how I contact Netgear. Click on "contact." But I can almost guarantee you, they are gonna have you do the same crap over & over. Its something w/their firmware.

I do wonder if the CPU on the device is underpowered and it stalls to keep up with the load of adding devices even though its a WiFi6 router.
Some advice, create backups of your settings regularly (I mean often). Also when restarting, completely power down the device meaning unplug the d**n thing for > 30s.
With the logs have useless information and an unreliable reboot/restart process its a crap shoot with this device. I've had my device for about 3 months and its rebooted multiple times and sometimes its seamless and other times it would reset to default.
my 2 cents
- My Samsung Galaxy S20 Plus is back to "connected, without Internet". Only solution is reboot router. Have to setup router as new to re-activate Internet with COX each time as well. Yeah, I agree.... Piece of S***. $500 wasted.
Then return it.
