Model: Deco X90  
Hardware Version:
Firmware Version: latest

Hello,

 

as X90 have same SSID for 2.4GHz and 5GHz, the Google Chromecast with Google TV works randomly in this network.

If it works, I can cast Youtube from my phone to the Chromecast

 

I can force it to work if I turn off 5G network, so to make all my device on the same side.

 

It work temporarily after I turn back on both 2.4G and 5G.

 

However, after some time, it looks like the router will do something such that even I see my phone and Chromecast is on the same network (e.g. SSID + same frequency), the phone cannot see the Chromecast.

 

There has no other configuration in the app that allow me to try to fix it. Can you take a look? I am happy to help if you may need more info from my side.
(I am a software engineer so I should able to follow your technical instruction)

  @BonBonBon 

Hi, have you checked when the smartphone failed to cast to Google TV, are they connected to the same Deco or a different Deco X90?

There are some suggestions for your reference:

1. Please try to connect the Google TV via Ethernet connection if possible.

--If not, please connect Chromecast TV to 5ghz, then turn off "Mesh Technology" on the Chromecast TV.

2. Reserve a fixed IP address for the Chromecast TV.

 

Thank you very much.

Best regards.

- same Deco, yes; because there is only 1 Deco in this network

 

- mesh technology; turned off but does not help.

 

- let me try the reserved IP. But may I know once a device has a reserved IP, does it means it will stay on the same frequency?

Hi, reserving IP would only make TV get the same IP address every time it reconnects to Deco.

And Does it help with address reservation?

If not, how often are you able to reproduce this issue?

By the way, please also turn off "fast roaming" under Deco APP>More>Advanced>Fast roaming.

Thank you very much.

thanks for the further information. Will definitely try it out.

 

One question: may I know in the Deco, in the main network (not the guest one) is there any AP isolation / client isolation?

 

I have another home has Deco M9 Plus (2 M9 plus devices in the same network) and never have the similar problem. But now even one X90 has it.. so I wonder if internally in the X90 segment / isolate the client.

 

I can check by doing some port scans but i think your information will be more reliable.

 

thanks!

  @BonBonBon X90 is incompatible with almost all IoT devices from all brands (even TAPO, which are made by TP-Link themself) and TP-Link know about that. However they are unable to solve the issue, because you know - they already sold the product and they don't care.

  @Momcho I can feel your frustration. I have M9 plus in another home and it did take me quite some time to resolve similar issues. e.g. the first few months the Dyson Link never work in that network.

 

I have no experience with other mesh solution so I am not sure if that is the problem of TP-Link or the protocol itself.
