Okay. Here’s my interaction, word-by-word, with Orbi Technical Support regarding my issues connecting my new Samsung 800 Series TV, Amazon Echos, Amazon Fire Stick, and other touchy/sensitive devices. I was using a CenturyLink DSL router with a 40/5 subscription when this all started. Updgrading to a new CL DSL router with a 100/10 subscription didn’t change a thing. Since installing the Orbi system, the CL router was disabled by the installation crew to limit WiFi interference. Not sure if the that was the smartest thing. Likely would have limited my frustration, but the speed would have really lagged not going through the Orbi. Hopefully this helps if your situation is like mine. I just wish NETGEAR would provide some tweaks to their system since my issues aren’t isolated. This problem appears to be rampant. Good luck!
Here is my conversation:
“Can you login to www.orbilogin.net ?

Trying, but I’m not sure of my user name.
Visitor • 6:50 AM
Username: admin
Password: password (what you registered with)
Kean P • 6:50 AM
Try to proceed on step number 2 on this link if you will not be able to login. https://kb.netgear.com/24220/How-do-I-recover-my-password-on-my-Nighthawk-router
Kean P • 6:51 AM
Got in. It just gives me a screen that tell me that Orbi’s IP number was updated to 10.0.0.1 to avoid conflict with my ISP.
Visitor • 6:53 AM
That means the CL router is not setup to bridge. Can you try to connect your devices that has problems connecting to the internet and check if they are working right now?
Kean P • 6:54 AM
Connect those device to the ORBI WiFi and check if they will be able to browse.
Kean P • 6:54 AM
Ok. I’ll try. Hold on.
Visitor • 6:54 AM
Nope. Still gives me a network error.
Visitor • 6:56 AM
The TV says it’s connected to the Orbi with good speed, but no internet.
Visitor • 6:57 AM
My phone is on the same router and working great.
Visitor • 6:57 AM
I unplugged the RBW30 satellites to simplify things for now.
Visitor • 6:58 AM
Alright please proceed to BASIC > Internet and make sure that the IP address is on Get dynamically from ISP and the DNS is on get automatically from ISP.
Kean P • 6:59 AM
Then proceed to ADVANCED > Security > Access Control. Make sure that is is on Allow all new devices to connect.
Kean P • 6:59 AM
Ok
Visitor • 6:59 AM
Hold on
Visitor • 6:59 AM
Confirmed both on BASIC are as you listed.
Visitor • 7:00 AM
ADVANCED is as you stated it should be.
Visitor • 7:01 AM
Is the access control enabled?
Kean P • 7:01 AM
If not please enable it.
Kean P • 7:02 AM
It’s checked. So I assume so.
Visitor • 7:02 AM
Then go back to BASIC > Wireless and change the 2.4GHz channel to 01 and the 5GHz channel to 36. Apply the settings.
Kean P • 7:02 AM
Then proceed to ADVANCED > Advance Setup > Wireless Settings and check for CTS/RTS Threshold for both 2.4GHz and 5GHz change the current value to 2304.
Kean P • 7:03 AM
Apply the settings after.
Kean P • 7:03 AM
Ok. I got a security warning.
Visitor • 7:04 AM
Says WPA-PSK may only operate up to 54Mbps, not N rate.
Visitor • 7:04 AM
Please proceed.
Kean P • 7:05 AM
Says I should use WPA2-PSK. Should I change this?
Visitor • 7:05 AM
Can you please check the security option? Make sure that it is on WPA2-PSK [AES]
Kean P • 7:05 AM
Ok, I will.
Visitor • 7:05 AM
It’s thinking afte the BASIC changes
Visitor • 7:06 AM
Now going to advanced
Visitor • 7:07 AM
Alright please tell me once done.
Kean P • 7:07 AM
Done
Visitor • 7:10 AM
Alright please disconnect your TV and all other devices to the WiFi and reconnect back to ORBI WiFi,
Kean P • 7:11 AM
Check if you will be able to access the internet now.
Visitor • 7:12 AM
Yes! I can. Thank you!

Thanks for these details. I'm glad that your contact with NG support resulted in positive improvement. From the details that you listed I guess these what helped:

1. I think this is the most important. There was an IP conflict between your ISP router and Orbi. Orbi now changed to a new IP range (10.0.0.x) which removed the conflict. I gues that you still need to bridge your ISP router or configure the DMZ if you don't want to get more issues in the future.

2. The WPA vs WPA2 might also affected the TV attach procedure.
