Update downloading delay with certain Wi-Fi routers
STBC (space-time block coding) is an optional feature in 802.11AC. It allows a transmitter to transmit multiple copies of data streams using a number of antennas. It also allows a receiver to select the best copy of data among those multiple copies to improve reliability. There is an inter-operability issue between Google Home and certain models of 802.11AC routers that use this feature on 5GHz Wi-fi. This could result in a slow download of the initial OTA (Over the Air Update).
If your router is on the list below, please factory reset Google Home and re-setup on 2.4GHz Wi-Fi. Once setup is complete and the update is complete, you can switch back your Google Home to a 5GHz Wi-Fi network using the Google Home app.
