Model: Deco M5  
Hardware Version: V3
Firmware Version: 1.5.7 Build 20210819 Rel. 43499

Hello,

 

My WiFi network uses:

  • Deco M5 v3 1.5.7 main unit
  • four Deco S4 v2 1.5.0 units 
  • Cat6A backhaul
  • ~30 online clients

 

Some WiFi clients just don't respond to pings everytime.

 

I installed quite a few smart home devices (eg. Tapo P100, Philips WiZ).

Remote controls works all the time through each manufacturer's app.

 

I am working on setting up local control with HomeAssistant; it works with one exception:

If I don't use some devices for a while, they will (individually) stop responding to local calls/pings/actions.

 

Pinging them with local IPs (192.168.68.*) gives me 'hostname unreachable'. They act offline to my network, but at the same time, I can trigger them via cloud apps; so they are always online.

 

This issue is temporarily solved by using the 'Optimize network' feature from the Deco app. Pinging works after optimization.

 

I switched my Decos from Router mode to AP mode (with a classic Asus router). I turned off Mesh (seamless roaming?) for the affected devices and the problem persists. I called tech support (Romania) and they didn't have a solution.

 

Any thoughts?

Hi, thank you for your time and patience.

I would like to forward your case to the senior engineers.

Please check later whether you could get an email from us.

At the same time, could you please help me check the following information:

1. Apart from P100, what are other smart home devices that were affected? And can I have their model number?

2. Before using Deco Mesh, were you having the same issue on the Asus router? And may I know the model number of your Asus router?

3. How often would this issue repeat?

@TP-Link 

 

1. Any Philips WiZ lightbulb, a Toshiba Satellite laptop.  

2. I didn't have smart devices at that time.  

It turns out switching to AP mode and using my older router fixed the issue. And Decos work well as acces points. It's an ASUS RT-N18U.  

3. It would repeat 2-3 times per day, one device not responding at a time.
