I'm trying to setup both a Google Nest Home Hub Max and Mini Speaker.  I'm using the Google Home App via my Pixel 6a which is connected the TP-Link Deco WiFi network.  Neither can complete the setup because they insist the network AP is isolated.

I can confirm and have tried:

• Device Isolation is disabled
• Beamforming disabled
• Fast Roaming disabled
• 2.4Ghz only enabled (tried)
• Using IOT Network (tried)

None of these solutions work.  My Google devices were working fine, but I changed the SSID+password and reset the devices.  (I can't recall exactly, but I might have set them up with the old router before I bought the TP-Link Deco XE75 Pro and then just used the same SSID+password.)

Phones, computers, smart TVs all connect without issue.  Even the Google Nest Doorbell connected fine.  Just not the Nest Home Screens and Speakers.

Anyway, if I can't fix this, I'll have to throw the Deco in the trash. :/

Can anybody help?
