Nighthawk CAX80 Connectivity Issues with 2018 Samsung QN55Q6FNA TV Plus
I have also posted this to Samsung community boards because at the moment I'm still not sure who owns this issue! To start off this long winded explanation of a problem I will say I have a 2018 S...
WOW.. I thought I was the only one! I am having the EXACT same issue with my CAX80 modem and my Samsung TV. I too have a 2018 model, but mine is 75 inch... in addition to tvplus not working, I have similar issues with an app called Klowd TV and also CBSN streaming news app. All the other apps on the tv seem to work fine.
I have been getting the same run around between Samsung and Netgear, but I am certain the problem is with the Netgear gateway as the problem didn’t start until after I did a modem firmware update.
I currently have an open ticket with Netgear, and about once a week the so follow up with me but so far they have been unable to rectify the problem.
In addition to the aforementioned apps not working, when Samsung connected to my tv remotely, they were able to do network tests on my tv/modem connection. They advised that the connection, when connected to my Netgear cax80, was “unstable”. I have also gotten this “unstable connection” error message when attempting to check for tv firmware updates.
Since Netgear so far has been unable to fix the problem, I purchased an Apple TV so that I can use the apps that won’t work on the TV itself. While the apps do indeed work, I’ve noticed frequent buffering and intermittent connection issues.
My spouse also said they’ve noticed Intermittent connection problems with his iPhone.
Anyway, I have done all the same troubleshooting steps you did, and then some. None have worked. Personally I think this modem is not ready for prime time. I certainly would not recommend it to others until after these kinks are worked out. It’s extremely frustrating.

- I’m writing this on my phone so forgive my typos... But if you don’t mind, please let me ha know on this forum the outcome of your situation. I will do the same.
Even more crazy is that my house was also struck by lightning and the mother board on this tv was also fried and replaced. I don’t think that’s the cause of this issue because like you, when I connect the tv to my hotspot, everything works fine. Samsung even confirmed that my network was not having any “unstable” errors when connected to my hotspot. The problem strictly exists with the CAX80.
Anyway, keep me posted - dying to straighten this thing out!- So Netgear replaced my modem. I again reset my tv to factory settings, connected it to the new modem, and still it doesn’t work. But if I connect it to my hotspot, the tv and all apps work flawlessly.. there is clearly a design flaw with this modem. At this point, I’m am fed up with this. I didn’t sign up to be a guinea pig. I just want my internet to work.
So if you temporarily disable WPA wifi security on the modem and have your TV connect to it, does it connect. After trying this, re-enabled WPA and TPIK and try the TV. Then try WPA2 and AES only.
Be sure the TVs firmware is up to date as well. This maybe a problem at the TV if this is the only device having problems.
"I just want my internet to work." is your internet service not working with this modem from your ISP?
