You open the Google Home app, tap your Nest Hub Max, and see that gray "Offline" tag staring back. Voice commands get nothing, the screen won't load your smart home controls, and the device can show as online for hours before quietly vanishing from the network without an obvious trigger.
Start with the simplest fix. Pull the power cable from the back of the Nest Hub Max, count to 30, plug it back in. The Google logo appears while it boots and rejoins your network. If the Home app shows it online within two minutes, you're done. If not, keep working through the list.
Why Your Nest Hub Max Goes Offline
The Nest Hub Max relies exclusively on Wi-Fi, it has no Thread radio, no Zigbee, and no backup Ethernet port. Most disconnections trace back to one of a handful of causes.
- Router restarted in the background: ISP firmware updates often reboot the router silently overnight, and the Hub sometimes fails to reconnect cleanly.
- DHCP lease expired: your router handed the Hub an IP address that has expired, and the device hasn't requested a new one.
- Band steering glitch: the Hub tries to roam between 2.4 GHz and 5 GHz bands and gets stuck where neither band is strong enough.
- Matter hub session is hung: the Nest Hub Max acts as a Matter controller, and a stuck commissioning request can pull the whole device offline.
- Gemini for Home migration in progress: if your account is part of the early access rollout, the transition between Assistant and Gemini can briefly break the connection.
Confirm the Rest of Your Wi-Fi Is Alive
Before you dig into the Nest Hub Max, check if the rest of your network is working. Open a webpage on your phone while connected to Wi-Fi and toggle cellular data off. If your phone is also struggling, the problem is your router or modem, not the Hub.
Reboot the router by unplugging it for 60 seconds. The Hub will likely reconnect on its own once the router is back online. If your phone is fine and only the Hub is offline, move on to the next fix.
Power Cycle the Hub Properly
Unplug the cable from the Hub itself (not the wall) and wait a full 30 seconds. That gives the internal capacitors time to discharge completely. Reconnect the power and watch for the white Google logo on the screen.
The Hub takes about 60 to 90 seconds to boot up. Once the home screen appears, open the Google Home app and confirm the device shows as online.
Reconnect to Wi-Fi via the Google Home App
Open the Google Home app, press and hold the Nest Hub Max tile, and tap Settings > Wi-Fi. Forget the current network, then tap to reconnect and re-enter your password. If you recently changed your Wi-Fi password, this is almost certainly the fix you need.
If your router broadcasts 2.4 GHz and 5 GHz as separate SSIDs, pick the 5 GHz band for the strongest performance. The Nest Hub Max does not support Wi-Fi 6E or 6 GHz bands, so a combined SSID with aggressive band steering toward a band it can't use can cause the device to get confused.
Renew the DHCP Lease on Your Router
If the Hub shows offline just minutes after successfully reconnecting, your router may be issuing it a conflicting or stale IP address. Log into your router's admin panel, find the DHCP client list, and remove the entry for your Nest Hub Max. Then power cycle the Hub so it requests a fresh lease.
On most consumer routers this lives under Network > LAN > DHCP Server. If you're not comfortable poking around in your router settings, just rebooting the router accomplishes the same thing in the vast majority of cases.
Move the Hub Closer to the Router Temporarily
If your Nest Hub Max is more than 30 feet from the router or separated by multiple walls and large appliances, the signal strength can drop low enough that the device gets silently kicked off the network. Move it within 10 feet of the router for a test. If it stays online consistently in the new location, you've got a coverage problem, not a device problem.
Adding a mesh Wi-Fi node in the original room solves this. The Nest Hub Max works particularly well with Google Wifi or Nest Wifi routers, but any mesh system that provides strong coverage will do the trick.
Check Google Services Status
If multiple Google Nest devices show offline simultaneously but your home internet and other Wi-Fi gadgets are working fine, the problem might be on Google's side of the connection. Check the Google Workspace Status Dashboard or search social media for "Google Home down." Cloud incidents can take Nest Hubs offline temporarily, and no device-side fix will restore service until Google resolves the outage on its end.
Force a Firmware Update Check
Google pushes firmware updates to Nest Hubs automatically, usually during late-night idle windows. To trigger a check manually, leave the Hub plugged in and untouched for about 30 minutes. The device pings Google's update servers when it's idle. Power cycle the Hub when you come back, the new firmware installs during the boot sequence.
You can confirm your current firmware version in the Google Home app under Settings > Device information > Firmware version.
Remove and Re-add the Device in Google Home
If the Hub is connected to Wi-Fi but the Google Home app insists it is offline, the account binding is likely out of sync. Open the Google Home app, press and hold the Hub tile, tap Settings > Remove device. Confirm the removal, then tap Add > Set up device > New device and walk through the full setup process again.
This process removes any routines or automations tied to that specific Hub. Your Google account and other smart home devices remain intact and will re-link automatically during setup.
Factory Reset as a Last Resort
The Nest Hub Max factory reset wipes everything, your settings, linked accounts, Wi-Fi credentials, and paired smart home devices. There is no way to undo it. Hold both physical volume buttons on the back of the device simultaneously for 10 seconds. The screen goes dark and the Google logo appears as it resets. After the reboot, you will need to set it up fresh from the Google Home app.
If the Hub fails to complete the reset after two attempts, the issue is likely hardware-related rather than a configuration glitch. For a simple soft reboot without losing data, just unplug the power cable and plug it back in, there is no separate hardware soft reset button on the Nest Hub Max besides that power cycle.
