Wi-Fi trouble on a Nest Hub (2nd gen) shows up as a Hub that says it cannot connect, drops during video or music, or shows offline in the Google Home app. A smart display sits in one place, so the first test is signal: stand where the Hub sits with a phone and look at the Wi-Fi strength, because a Hub in the far corner of a house or behind a thick wall is the commonest cause. After that the router matters: the Hub joins 2.4 or 5 GHz networks, and a router that steers devices between bands, or one with a crowded channel, can cause drops. Change the router's channel, give the bands different names, and move the Hub or add a mesh node if the signal is weak.
After a router or password change the Hub must be told the new details in the Google Home app, under the Hub's settings, Wi-Fi. A Hub streams video and music, so a connection that is fine for a phone can still stutter on the Hub if the router's upload or the channel is busy. Test by playing a YouTube video on the Hub at different times of day: if it buffers only in the evening, the network is congested, and a less crowded channel or a wired mesh node fixes it. The Hub also shows its own network status: swipe down, Settings, Wi-Fi, and read the signal and the network name it has joined, which tells you whether it joined the network you intended.
Differential
Likely causes of “Nest Hub (2nd gen) will not stay connected to Wi-Fi”, and how to tell them apart
- 1
A weak signal where the Hub sits
What separates it The Hub drops during video or says it cannot connect
How to confirm Move the Hub or add a mesh node closer to it
- 2
Band steering or a crowded channel
What separates it The Hub drops at busy times
How to confirm Give 2.4 and 5 GHz separate names and change the router's channel
- 3
A changed router or password
What separates it The Hub stopped after a change
How to confirm In Google Home, the Hub's settings, Wi-Fi: choose the network and enter the new password
- 4
A router that needs a restart
What separates it Several devices drop
How to confirm Restart the router and the Hub
- 5
A Hub that has gone offline after a power cut
What separates it The app shows offline
How to confirm Unplug the Hub for ten seconds and restart the router
Before you touch a setting
Record this first — changing settings destroys the evidence
- The Wi-Fi strength at the Hub's position
- The router model and band
- Whether a router change preceded the problem
- Whether other devices drop at the same time
Try in this order
0 of 9 completedMeasure the signal
ReversibleStand where the Hub sits and look at your phone's Wi-Fi strength on the same network.
Restart the Hub and the router
ReversibleUnplug the Hub for ten seconds and restart the router, then wait for both to settle.
Reconnect to the right network
ReversibleGoogle Home, the Hub, Settings, Wi-Fi: choose the network and re-enter the password.
Separate the bands
ReversibleGive the router's 2.4 and 5 GHz bands different names and join the one with the stronger signal at the Hub.
Move the Hub or the router
ReversibleBring a node or the router closer to the Hub, away from microwaves and thick walls.
Update the Hub
ReversibleThe Hub updates itself over Wi-Fi; a stable connection for a few hours lets it install.
Read the Hub's own Wi-Fi status
ReversibleSwipe down on the Hub, open Settings, Wi-Fi, and check which network and band it joined and how strong the signal is, because a Hub joined to a distant guest network behaves badly.
Test video at different times
ReversiblePlay a video at several times of day; buffering only in the evening points at congestion, not distance.
Use a wired mesh node if possible
ReversibleA node connected to the router by cable gives the Hub the strongest and steadiest link.
Model-specific
What is true of this model and not of its siblings
- A fixed position
- Because the Hub does not move, a weak spot never improves on its own.
- After a router change
- Smart displays need the new network details in the app.
- Congestion
- Evening buffering suggests a busy channel or upload.
- Which network it joined
- A Hub can end up on a guest or distant network after setup.
- Wired backhaul
- A mesh node with a cable to the router is the steadiest.
Stop boundary
When this stops being a self-service repair
- !If the Hub drops on a strong signal on two routers, contact Google Nest support
- !If only this Hub drops, a replacement may be needed
- !If the router is the issue, ask its maker

Exact questions
Common questions
Why does my Nest Hub keep disconnecting from Wi-Fi?+
Usually a weak signal where it sits, or a router that steers it between bands.
Does the Nest Hub use 5 GHz?+
It joins 2.4 or 5 GHz; the stronger band at its position works best.
How do I change the Hub's Wi-Fi network?+
In Google Home, the Hub's settings, Wi-Fi.
Should I reset the Hub for Wi-Fi problems?+
Only after the other steps.
Why does my Hub buffer only in the evening?+
The network is congested then.
How do I see which Wi-Fi the Hub uses?+
In the Hub's Settings, Wi-Fi.
