@Joseph-TP I manage 4 deco networks of which 3 are behaving fine.

The fourth network is the biggest and is causing problems:
# 7x deco P9 first generation units, 5 are connected by ethernet in series and two are operating as wifi/powerline satelites

# firmware updated over the last few days to the latest verion

# there are about 30 devises connected to the network, inclusing:

~10x P110 smart plugs

~ 8x Euphy cameras

~ 2x computers

~ 3x mobiles

~ 2x H100 hubs with about 15x sensors connected to them, mainly temperature / humidty  

~ various other smart devises (TV's, weathers station etc)

Having reset / rebuilt the entire network and upgraded to the most recent firmware I'm finding the network is now performing fine, but the Deco App fails to recognise most of the Deco P9's (which is problomatic for future firmare upgrades). So I'm wondering if the problem is more with the App than the Deco units themselves.

Hi

 

@DiceKey When you change it to access point mode, you do not need to reset it.

 

@DiceKey @garsdalian @FrancoIngham   We appreciate your concern, and we will escalate this matter to our support engineers for a thorough evaluation after collecting the information below.

 

Please kindly provide the following details:

1. If you oversee multiple Deco networks concurrently, could you please furnish the quantity, model, hardware version, and firmware version of the Decos within the problematic Deco network?
2. Are there multiple smart home devices connected to the problematic Deco network? If so, how many samrt home devices are currently linked to the problematic Deco network? And what are the model numbers of the smart home devices?

Wait for your reply and warm regards.

  @Joseph-TP Hi, I've set my main Deco as an access point, and will observe if there will be any changes. 
 

Is there any way to configure the ISP modem/router so that I won't have to make the Deco an access point? I don't want to lose the Parental Controls and QoS features of the Deco. 

  @Joseph-TP I tried resetting all Decos (hard reset by pressing the reset buttons on all Decos) and the problem is still there. 
 

Even after adding just one Deco, the satellite Deco still intermittently shows as offline, even if the light is green. 
 

Is there a problem with the Deco app, or even the cloud? Or is there a problem with the firmware? All my Decos have the latest firmware. Hope you can respond. 

  @Joseph-TP Also, is it possible for you to troubleshoot my network remotely? I would be willing to give you permission. I've tried everything I could but my network is still really messed up. I think it would be helpful if you can check my logs. 

@Joseph-TP same problem here with Deco X50 (V1.20). App says deco is offline but light is green and I am connected to the X50. Latest firmware is installed.

What can be a solution?

  @David-TP Hello, it is only the satellite and I tried to install the beta firmware but then is says "Upgrade failed. Please select the latest version of firmware to upgrade."

Current firmware is: 1.4.5 Build 20240828 Rel. 84587

@David-TP is there already a solution?

Thank you!
