The four checks that bring most doorbells back
Ring or Nest, the offline story is nearly always one of three things: a flat battery, weak Wi-Fi at the door, or a router change the doorbell never heard about.
Check the battery before anything clever
Ring app → Devices → your doorbell → Device Health shows the battery level; Google Home shows the same for Nest. If it is flat, charge it properly: Ring batteries can take up to 10 hours on a 1-amp wall charger (charging shows green + amber lights; done = green only). A doorbell that died flat may need 30 minutes on charge before it will even reconnect.
Did the Wi-Fi change?
New router, new provider, or even a new Wi-Fi password means the doorbell is calling a network that no longer exists. Ring: Device Health → Change Network (or Reconnect). Nest: rejoin through the Google Home app. This is the single most common cause we see.
Restart the router properly
Half of “doorbell offline” is actually “router weird”. Unplug modem and router, wait 30 seconds, modem first, router second — full order here — then give the doorbell a few minutes to find its way back.
Restart the doorbell itself
Nest battery model: press the pin-hole on the back for 5 seconds. Nest wired: hold the button on the back about 10 seconds. Ring battery models: pop the battery for 10 seconds; wired models: kill the breaker for 30 seconds. (Ring’s setup button held 20 seconds is a factory reset — that is the last resort, not the first.)
Your front door is the worst Wi-Fi spot in the house
Doorbells live on an exterior wall, far from the router, often with brick, stucco or a metal door in the path — and they connect on the slower 2.4GHz band. The app tells you exactly how bad it is: Ring’s Device Health shows RSSI, and Ring’s own bands are on the right. A doorbell living at –75 will drop forever no matter how many times you reset it.
The fix is signal, not settings: a mesh node placed between router and door (Ring sells Chime Pro for exactly this), or repositioning the router toward the front of the house. That is a 20-minute job with the right meter — ours, for instance.
Heat and weak transformers
Two local realities: first, heat. Ring devices are rated to 122°F and will limit features and eventually shut down (and refuse to charge) when they cook; Nest’s battery doorbell shuts down past 104°F. A doorbell in direct west-facing afternoon sun here lives at the edge of its rating all summer — shade from an eave or a small hood genuinely matters. Second, old transformers: hardwired doorbells want 16–24 volts AC with enough capacity (10–40 VA); the 60-year-old transformer that ran your original ding-dong chime often cannot feed a camera. The tell-tale symptoms: the doorbell dies at night, goes offline right after someone rings it, or the app grumbles about power. A transformer swap is a small, cheap fix — and one we do with the breaker off, which is how you should too, or better, let us.

Quick answers
My hardwired Ring/Nest never shows 100% battery.
For Nest that is by design — hardwiring trickle-charges the battery only to about 80% to protect its lifespan. Ring hardwiring is also a trickle, not a full charger: heavy traffic can outrun it, so an occasional top-up charge is normal.
It goes offline every night, back every morning.
Classic weak-transformer signature on hardwired units (voltage sags when temperatures drop and other loads run), or a battery unit that can't trickle enough during the day to survive busy evenings. Check Device Health's power section — it will say if the power is poor.
Motion events are missing or the video lags badly.
That's bandwidth, not brokenness. Doorbells want about 2 Mbps of upload; measure at the door, not the couch. RSSI worse than about −70 means delays and gaps — fix the signal and the mystery misses stop.
Will resetting it lose my recordings and settings?
A restart (power-cycle) loses nothing. A factory reset (Ring: setup button 20 seconds; Nest: ~12 seconds on the pin) wipes the device's settings and needs full re-setup in the app — recordings in the cloud remain in your account.
Ring or Nest for a new install here?
Both survive Bakersfield fine if placed out of direct afternoon sun and fed properly. We install both weekly: choose by whose app and subscriptions you already live in. Wiring, transformer and Wi-Fi placement decide reliability far more than the logo does.
