"Ghost network" appeared with the same SSID

Model: Deco S7  
Hardware Version: V1
Firmware Version: 1.5.2 Build 20240927 Rel. 68997

Hello. I had been using my mesh network consisting of 3 Deco S7 units without any issues for a long time. After running some tests, I realized that two units provided sufficient coverage and speed, so I decided to remove one of the units. Using the Deco app, I first changed the main Deco, then removed this "old" main Deco from the network. When I did this, the removed unit reset itself and its light turned blue. Everything was normal up to this point. However, after connecting the new main unit to the ONT device and regaining internet access, I noticed that a new network with the same SSID had appeared in the Deco app.

 

Currently, my network is working perfectly with two units (the main unit is connected to the ONT device and operating in PPPoE/router mode, and the second unit is connected via Ethernet to the main unit). However, in the Deco app, another network with the same name appears. This "ghost" network shows the unit I removed earlier, along with the two units I'm currently using. Naturally, this network is offline and I can't access it.

 

My concern is that if I delete this old network, my currently functioning network might also be deleted, since the two devices listed under the old network are also part of the active network with the same name.

 

Why could this have happened, and if I delete the old network, will my new network that includes the same Deco units also be deleted?

 

Both of my Deco S7 units are running the latest firmware (1.5.2 Build 20240927 Rel. 68997).

Hi, Thank you very much for the feedback.

If I understand it correctly, now there are two Mesh Networks with the same SSID on the Deco APP now:

Network#1, only two Deco S7 with a new main Deco.

Network#2, 3*Deco S7, and the "old" main Deco that has been reset and removed from the network.

 

It is suggested to detect the Deco APP and install it again, then log in to the Deco APP via mobile cellular data to see whether "Network#2" still shows up.

The current reported issue is more like this post, and the "Network#2" should be the network caches previously saved in the Deco APP.

Deco App Won't Allow Deleting Old Mesh Network

 

Wait for your reply.

Best regards.

Unfortunately, deleting and reinstalling the Deco app did not help when trying to log in using mobile data. As shown in the screenshot I attached, there are now two networks with the same name. The old network had three units named "Garage" (main unit), "Living Room," and "Bedroom." First, I set the unit named "Living Room" as the main unit and then removed the "Garage" unit (the device was reset normally). After internet access was restored, another network with the same name appeared, and I am currently using that one. However, the old network still shows three Deco units, and two of them — "Living Room" and "Bedroom" — are also active under the newly appeared network with the same name.

 

I'm worried that if I delete the old network, the new one will be deleted as well.

Hi, Thanks for the update.

Could you please refer to this link to help me submit the Deco APP log:

How to submit Deco APP log

 

Personally, I don't think it would affect the other network. As I can't be 100% sure,  perhaps you could help me collect the APP log, and I can invite the engineer for a double-check.

Wait for your reply.

Best regards.

Thank you for your interest. As you mentioned, I’ve sent the logs via the Deco app. To make it easier for you to find, I also included the link to this topic in the suggestions, opinions, and questions section.

Have you had a chance to review the logs I sent?

Hi, thanks for your time and patience.

There hasn't been a further response from the engineer about the Deco APP log yet.

But I've checked with the engineer that deleting the old offline network from the Deco APP will not affect the new online Deco S7 network, even though they have the same SSID.

Best regards.
