ER7206 - fail over doesn't

Hello everyone
I have two internet feeds coming in, one primary att fiber , and one secondary cable Internet from Xfinity
The att box is a router itself and when it loses Internet service it self routes all traffic back to it's self to display a configuration page when it's unable to reach out to the web. This generates a situation where the ER7206 router fails to see this as an outage and doesn't swap to the backup Internet.
The only way to get it to function correctly is to remove the att box from the 7206 router (power off or remove the Ethernet) so that it no longer sees it, only then will it actually swap as designed.
As you can imagine, this is less than ideal , and I'm not sure how to remedy this.

@Doc757 See page 97 of the User Guide for details on how to configure Online detection. By default , Auto will use a DNS lookup to determine if the WAN is online. The problem is that your router 'fakes' a DNS reply when its offline, so the ER7206 gets a response to its DNS lookup and thinks its online. Try changing the online detection to Manual and set it to ping an IP instead . Set the ping IP to 1.1.1.1 and make sure you set the DNS lookup to 0.0.0.0 ( Disabled ).
That should work

Thanks for your answer. I use Omada Cloud.
Here is the config.
For DNS, there is only this place that found.
With
8.8.8.8
1.1.1.1
it does not work!
Can you explain to me on the images what I have to do exactly!?
Thanks for your help.

Sorry , I've never used the Omada controller software I've only ever used the routers standalone. There ought to be somewhere in the controller that allows configuration of the Online detection
This https://community.tp-link.com/en/business/forum/topic/611884 might help

Hi @xpancadax
Thanks for posting in our business forum.

Did you read and try to understand the article that MisterW shared with you?
If you don't understand a part, specify it and say what you understood or interpreted.
I don't see the point in your pictures. Do you expect us to tell you what you should configure with a static IP on your 5G connection?
Nope. That's something we could never tell you what to do. Contact your ISP regarding that issue if you don't know what to configure in that part. All the WAN information is not known to us. Your ISP is the sole owner responsible for your IP and WAN config.
About your question, you should give more details about it. It does not switch, how do you verify it? Not a single line "it doesn't switch". I don't understand and it is meaningless to me. I don't know how you verified it and if your method is correct or not. Basic communication skills to reach the same page before further discussion.
It is also the reason why I did not reply to your post in the first place. It is way too ambiguous and emotional. I don't respond to ambiguous descriptions.

Have you read and tried to understand the article that MisterW shared with you?
Absolutely, but unfortunately on page 97 I can't find any information about failover or load balancing.
If you don't understand a part, specify it and say what you understood or interpreted.
It's simple:
1 a fiber access - router in DHCP - WAN 2 - Primary
1 an LTE access - router in DHCP - WAN/LAN3 - Backup
Link Backup enabled works if the physical LAN ethernet cable is unplugged.
But who will come and unplug the LAN cable in the rackmount on the ceiling?
I want that as soon as the ISP no longer broadcasts a signal, the TP-link must switch. It doesn't do it, that's my problem.
The TP-link also broadcasts DHCP.
I've seen a lot of things about DNS lookup, but as described in lookup, there is no such function.
Just DNS Server in Omada. Are we talking about the same thing already?
Is DNS Server the DNS lookup in Omada cloud?
Maybe the controller just doesn't allow it!
Maybe the controller wants to have a local static IP.
I tried DNS, Gateway, DNS google, cloudflare. ect..
I don't see the point of your pictures. Do you expect us to tell you what you need to configure with a static IP on your 5G connection?
First of all because many work in Standalone, on Omada Cloud there are missing settings.
I just want to understand as explained above if I have to put static IPs in the subnet of my WAN's for the TP-link to switch.
No. This is something we could never tell you what to do. Contact your ISP about this problem if you don't know what to configure in this part. All WAN information is not known to us. Your ISP is the only owner responsible for your IP and WAN configuration.
I don't want to make the TP-link in router mode. I'm in charge of local IPs. If there is a configuration that works, I'm trying to understand how! I don't need you to tell me to put 192.168.35.20
255.255.255.0
192.168.35.1
Rather than
192.168.40.10
255.255.255.0
192.168.40.1
I just want an example of a good configuration so that the Online detection is done!
About your question, you should give more details about it. It doesn't change, how do you check it? Not a single line "it doesn't change". I don't understand and it doesn't make sense to me. I don't know how you checked it and if your method is correct or not. Basic communication skills to reach the same page before continuing the discussion.
I didn't dare to test with a fake DNS, because otherwise I have to do resets again. I spent 5 hours on it! I tried a lot of things.
But not the standalone.
This is also the reason why I didn't answer your message in the first place. It's way too ambiguous and emotional. I don't answer ambiguous descriptions.
Don't answer at all then!
Again the question is rather simple.
First question: Omada Cloud, can it or not allow Online detection? ISP signal disconnected, not LAN
Second question: Why if I disconnect LAN failover doesn't work!
Thanks ^_^
Best regards too

I like that you keep trying , kudos
I gave up while ago and chalked it up to terrible programming from the development team

About the controller part:
Figure this out, Omada Cloud Controller, right? Is that the basic or standard you are using now?
Basic controller is free and hosted on the cloud and ONLY offers limited features. It is not the complete controller we refer to. The community talks about the standard one which you deploy in your local computer and bind it to the cloud. Hosted by yourself locally and provides 24/7 Internet and power-on.
The Basic Controller was only added a few months ago for a preview or users who don't need fancy functions.
If you want a complete controller, go for the standard one.
Or pay for the annual license for complete, standard, and hosted on the cloud controller. That's how the controller works. There are tons of guides and FAQs regarding the differences in Omada Controller.
If you find your controller different from others, go to the Controller page and consult with the community or check yourself with FAQs on Omada Controller. Too many guides to paste here or start with.
I personally do not recommend anyone with the basic controller. But the choice is yours.
Honest suggestion, start with the standard local controller and get familiarized with it before you switch to one entirely based on the cloud.
Every senior community member is pretty familiar with the local controller. We often refer to the functions that are plain and obvious on the controller. Skip this part and jump into the cloud, that only confuses you.

About the "router thing":
Return it if you don't want the router to be in "router mode". This is a router and we don't have other modes. Or "load-balance only" mode.
About the online detection:
The Controller mode requires the Echo Server to ping it and detect if it is online or not. Or don't set that, it will still ping to detect the online status.
Read the KB again? What part did you not understand and highlight it?
Failover, it does not instantly switch to the backup WAN. Did you really read the KB I wrote? It requires several ping results as failed before it switched.
Online detection interval only determines how many seconds between each ping is sent, it can increase the switch speed but it does not mean it will switch by the second when the primary is down.

As I explained on earlier posts, that refers to the User Guide for operating the ER7206 in Standalone mode.
TBH Unless you have many other Omada devices you wish to manage, I dont understand why you would wish to operate in controller mode.
