Model: Deco S4  
Hardware Version:
Firmware Version: 1.5.0 Build 20210607 Rel. 56436

Hi,

 

I've just migrated from a single access point to a Deco Mesh system, using 3x S4 Decos.

 

Everything is working just fine except for Google Speaker Groups. I am able to cast to each speaker individually, so they are all present on the network.

But, if I attempt to cast to a group, it fails to establish the connection to cast to the devices.

 

I *believe* that this only happens if the different speakers are connected to different physical Deco access points; I think that if all speakers in a speaker group are connected to the same physical access point, it works OK.

 

I suppose it might be that some of the speakers are connected to 2g4 and some to the 5GHz connection, but I cannot easily determine this.

 

Either way - surely the point of a mesh network is that any device connected to any access point on either band should act together as if it is on the same network?!

 

Thanks,

Ralph Sawyer

Hi, have you seen the following instruction on Google support:

And they also provide troubleshooting to help locate some details.

It would be highly appreciated If you could let me know which step went wrong and the error message.

@TP-Link 

 

Thank you for your reply. 

Most of those articles are about basic speaker group set up, for which I haven't had problems.

 

This is interesting though:

extract:

Q: Do I need all of the speakers to be on the same network in order to group them?

A: Yes. To successfully group the speakers, you will need to connect all of them to the same network. Note: Dual-band access points (5 GHz and 2.4 GHz channels), wired connection (Ethernet) and connection through Wi-Fi extenders are all supported with group playback. Make sure that you disable AP/Client isolation on your Access Point/Extender and that Multi-cast forwarding is not disabled between the W-Fi networks.

 

So - could you advise how I do these actions in Deco:

  • Disable AP/Client isolation on your Access Point
  • ensure that Multi-cast forwarding is not disabled between the W-Fi networks

 

Note that in my setup, the Deco units are in AP mode, if that makes a difference. 

(i need to keep my BT Home Hub so I can have an IP landline).

So - could you advise how I do these actions in Deco:

  • Disable AP/Client isolation on your Access Point.

There is no AP isolation for the main network of Deco and you don't need to worry about this feature.

  • ensure that Multi-cast forwarding is not disabled between the W-Fi networks

 Please log into the web UI of Deco(How to log into the web-based interface of my Deco?) and under advanced settings>system parameters, please enable the IGMP.

Note that in my setup, the Deco units are in AP mode, if that makes a difference.
