Most cases trace back to Router uses 5GHz only; App permission denied; WiFi password incorrect. The fix works best when you go step by step instead of changing multiple settings at once.

Tools & Requirements
Step-by-Step Solution
Confirm 2.4GHz Network
Make sure the router broadcasts a 2.4GHz network. The TP07 does not join 5GHz only SSIDs.
Reset WiFi on the Purifier
Hold the power button on the remote for 5 seconds until the WiFi icon flashes. This clears previous network data.
Start Setup in MyDyson
Open the MyDyson app, add a device, and follow the prompts. Keep the phone close to the purifier.
Improve Signal
Move the purifier closer to the router for setup. After pairing, you can move it back.
Update Firmware
Once connected, check for firmware updates in the app to improve stability.
Quick Solutions
Still having issues? This is usually the deeper cause below.
This usually happens right after a router reboot or ISP change — the device rejoins the network but drops its cloud session silently.
Use a simple SSID name during setup. Long or special characters can cause pairing failures.
Most WiFi drop-offs happen right after a router reboot or ISP swap — the device reconnects to the network but silently loses its cloud registration.
- Router on 5GHz only
- App permission (Bluetooth/location) denied
- WiFi password entered incorrectly
- Router blocking device discovery
- Purifier needs a WiFi reset
