Tapo Camera 'Connection Failed' During Setup — Fix

What it means

'Connection Failed' while adding a Tapo camera nearly always comes down to Wi-Fi: the camera only works on the 2.4 GHz band, and modern routers often hide 2.4 GHz behind a single combined network name so your phone hands the camera 5 GHz details it can't use.
The other usual cause is a mistyped Wi-Fi password.
It's a setup-stage problem, not a faulty camera.

Affected Models

Tapo C100, C110, C120
Tapo C200, C210, C220 (pan/tilt)
Tapo C310, C320WS, C325WB (outdoor)
Tapo C420, C425 (battery)
Tapo TC65, TC70, TC71

Common Causes

Trying to join a 5 GHz network — Tapo cameras only use 2.4 GHz
Router combining both bands under one name, so the camera gets 5 GHz settings
Wi-Fi password entered wrong (it's case-sensitive)
Phone too far from the camera or the camera during pairing
Special characters in the Wi-Fi name or password the camera dislikes
Router's guest network or AP isolation blocking device-to-device setup
Camera not in pairing mode (needs a reset first if it was set up before)

How to Fix It

Confirm you're giving it a 2.4 GHz network.

Check your phone is on (or you select during setup) the 2.4 GHz Wi-Fi.
If your router uses one combined name for both bands, log into the router and either split them into separate names temporarily, or enable the option that lets a 2.4 GHz-only device join.
Re-enter the Wi-Fi password carefully.

The password is case-sensitive and a single wrong character fails the connection without saying so.
Type it slowly, watch for autocapitalised first letters, and avoid pasting if the keyboard adds a trailing space.
Reset the camera and start over.

If the camera was set up before, it isn't in pairing mode — press and hold its reset button until it chimes or the LED turns to the setup colour.
Keep the camera, your phone, and the router fairly close together while you run setup.
Turn off guest mode and AP isolation.

In your router settings, make sure you're not connecting through a guest network and that 'AP isolation' or 'client isolation' is off — those stop your phone and the camera from seeing each other during setup.
Try a phone hotspot as a test.

Create a 2.4 GHz hotspot on another phone, add the camera to that, and confirm it pairs.
If it works on the hotspot, the issue is your router's settings (band, isolation, special characters) — not the camera.

Frequently Asked Questions

How do I tell if my Wi-Fi is 2.4 GHz or 5 GHz?

Look at the network name — many routers label them, like 'MyWiFi' and 'MyWiFi_5G'.
If you only see one name, your router is probably broadcasting both bands together; you'll need to log into the router's settings to split them or to confirm 2.4 GHz is enabled.
Tapo cameras can only join 2.4 GHz, which is why this matters during setup.
