The Nest Hub Max screen stays on, showing your photo slideshow or the clock. But when you ask for a song or try to cast a recipe, you get the spinning circle and an offline error in the Google Home app. This is the most common complaint with this particular smart display, and it's almost never a hardware problem.
The quickest fix that clears this for most people: power cycle the router first, then the Hub Max. Unplug the router for a full 60 seconds, plug it back in, and wait 3 minutes for everything to come back up. Then unplug the Hub Max for 30 seconds and reconnect. Within 90 seconds, the Google Home app should show it online again.
Power Cycle in the Right Sequence
Order is important here. If you reboot the Hub Max while the router is still half-booted, it grabs a bad handshake and you'll see the same disconnect within an hour. Start with the router, wait for all your other devices to reconnect, then pull the Hub Max power cable for 30 seconds. When the screen comes back, you'll see the Google logo followed by the home screen.
The Hub Max doesn't have a soft reboot button arrangement. If you need to restart it without unplugging, there's no shortcut for that. The power cable pull is the cleanest way to force a full restart.
Forget the Network and Reconnect
Sometimes the credentials stored from the last connection get stale, especially after a router firmware update or an ISP modem swap. Swipe down from the top of the Hub Max screen and tap the gear icon for Settings. Go to Network or Wi-Fi, tap your network name, then select Forget. The Hub Max drops off the network completely. Tap the network again and enter the password fresh. This rebuilds the entire Wi-Fi handshake from scratch.
The Google Photos ambient mode bug is unrelated to this, but since you're poking around settings anyway, open Photos under Ambient mode in the Google Home app and make sure your albums are still linked. Some users report albums disappearing silently after firmware updates.
Try 5 GHz Instead of 2.4 GHz
The Nest Hub Max supports both 2.4 GHz and 5 GHz bands. Most routers put both under the same SSID and let the device decide, but the Hub Max sometimes picks the 2.4 GHz band by default and stays there even when 5 GHz has less interference. If your router has separate SSIDs per band, force the Hub Max to join the 5 GHz network.
Open the Google Home app, tap your Hub Max, then go to Settings > Device information > Wi-Fi. You'll see the current band listed. If it's 2.4 GHz, forget the network and connect to the 5 GHz SSID instead. The 5 GHz band gives you faster response times for music streaming and video calls with that 6.5MP camera, and it usually holds the connection more reliably for a stationary device like this.
Reserve a Static IP for the Hub Max
If the disconnects follow a predictable pattern, like every 24 hours or every 12 hours, the router's DHCP lease is likely expiring and the Hub Max is missing the renewal. The fix is to reserve a static IP for the Hub Max so it never has to ask for a new address.
Log into your router admin panel, find the DHCP client list, and look for the Hub Max. Reserve the IP based on its MAC address. The MAC address is listed on the Hub Max under Settings > Device information. Once reserved, the Hub Max keeps that same address forever and the drop-reconnect cycle stops.
Check the Signal Strength at Its Location
The Nest Hub Max has a 10-inch display, so you might have it sitting on a kitchen counter that's far from the router. Signal strength below about minus 70 dBm causes intermittent drops even when the Wi-Fi icon shows full bars. Move the Hub Max to within 15 feet of the router as a test. If the disconnects stop, the original spot has weak coverage.
Since the Hub Max is discontinued from the Google Store as of 2025, you'll want to preserve its hardware by not moving it around constantly. If weak signal is the issue, adding a mesh node or a Wi-Fi extender near its permanent location is the practical fix.
Change the Wi-Fi Channel on the Router
Channel congestion on 2.4 GHz is an under-diagnosed cause of Nest device disconnects, especially in apartment buildings where dozens of networks crowd the same frequency. Log into your router and switch the 2.4 GHz channel to 1, 6, or 11. Those three are the only non-overlapping channels, and moving to one that's less congested can stabilize the connection immediately.
Most routers expose this under Wireless > Advanced settings. If your router has automatic channel selection, disable it and set the channel manually. After changing it, reboot the Hub Max via the power cable pull and watch for drops over the next 24 hours.
Force a Firmware Check
Firmware updates for the Hub Max install automatically during idle time, but you can nudge it. From the screen, swipe down, tap the gear, then go to Settings > About device > Cast firmware version. Tap the version number 7 times. The Hub Max checks for a new firmware and downloads it during the next idle period. YouTube playback sometimes restarts after an update, but that usually settles after a day.
The Gemini for Home migration is rolling out across 16 countries as of April 2026. Some users see network instability during the migration window because the device is switching between Assistant and Gemini backends. Open the Google Home app and check for any migration banner. If your account is in transition, the disconnects may stop once the rollout completes, no manual intervention needed.
Factory Reset as a Last Resort
Hold both volume buttons on the back of the device for 10 seconds. The screen flashes, and the device boots into reset mode. This wipes everything: your Wi-Fi credentials, linked Google accounts, Voice Match enrollment, Face Match data, and all custom routines. It also clears any Gemini migration state that might be stuck. Set it up fresh via the Google Home app, and test the connection for a full day before adding your routines back.
