Transmitter 1 and wifi mesh interference

I have been experiencing interference between the transmitter 1 and wifi mesh (google) for a while. 
After about 10 seconds of the speakers become active the music stops. The google chromecast audio disappears from Spotify and I cannot access internet with the iPad. The speakers remain active as the red dot doesn’t appear.

After a 45-60 seconds starts again and plays normally.

Has anyone experience something similar and can advice a solution?

Does anyone know the benefits of the transmitter 1 update?  I have a pair of beolab17 bought about 6 years ago and never updated

Thanks in advance for your help

Transmitter 1 and WiFi 5GHz networks do not coexist very well.

The only way I managed to get them working side by side is to set the WiFi 5GHz to use DFS channels.

Can’t tell if Google kits support these channels.
