Having your extra wireless connections running simultaneously may be complicating the pairing process.

  1. Turn on Airplane mode.
  2. Turn on Wi-Fi, and make sure it’s on the same network as the Google Home Mini.
  3. Remove extraneous devices from the Wi-Fi network.
  4. Ensure both your phone and your Google Home Mini are adequately close to your Wi-Fi router.
  5. Retry the Google Home Mini setup. If your Wi-Fi network is hidden, you’ll need to manually input the ID under “Other” from the network selection drop-down list.
  6. If this doesn’t work, try re-enabling Bluetooth on your phone.
  7. If this doesn’t work, go into the Google Home Mini settings, forget the Wi-Fi network, and add it again.

Even after a reboot, your Wi-Fi router may be housing some suboptimal settings. Here’s what you can do to troubleshoot those issues:

  1. Try keeping only one wireless band (2.4GHz or 5GHz) active and connect to each individually as a test.
  2. If running on a 5GHz connection and the router is running DD-WRT firmware, set the wireless mode to “mixed.”
  3. Make sure your Wi-Fi router has Universal Plug and Play (UPnP) enabled.
  4. Make sure your Wi-Fi router has multicast enabled.
  5. Make sure your Wi-Fi router has Internet Group Management Protocol (IGMP) enabled.
  6. Make sure your Wi-Fi router has AP/client isolation disabled.
  7. Make sure your Wi-Fi router and computer have virtual private networks (VPNs) disabled.
  8. Make sure your Wi-Fi router has proxy servers disabled.
  9. Make sure your Wi-Fi router has IGMP Proxy disabled.
  10. Make sure your Wi-Fi router is using WEP, WPA, or WPA2 wireless security.
  11. Make sure your router has Band Steering (or Smart Steering) disabled during setup.
  12. If your router uses MAC address filtering, you’ll need to add the Google Home Mini’s address to your router. This address can be found in the top-right of the Google Home app during setup.

While many users access Google Home on their smartphone or smart display, the platform is also available via web browser. The web-based Google Home experience wasn't exactly the best way to access your smart devices, but that's rapidly changing as Google rolls out new updates to the client -- the latest of which adds a ton of new ways to access your Nest Cams.

Google began rolling out the update late last week, and most users should now have access to the improved Google Home for web experience.
