DIRECT ANSWER

Note where setup stops: finding the robot, joining its hotspot, joining your router or reaching Dreame's servers. Then use the app and pairing control your model's manual lists, on 2.4 GHz Wi-Fi.

What to check, in order

1

App or pairing control doesn't match the model

The manuals differ from model to model. F9, original D9, L10 Pro, Z10 Pro and W10 list Mi Home/Xiaomi Home. The D10 Plus lists either app, and the other models in the table list Dreamehome. The way to restart pairing differs too.

2

Phone permissions or leaving the hotspot too soon

The app uses Bluetooth and location access to find the robot, and Dreamehome may also need local network access. If you return to the app before the robot's voice prompt, the handover can break.

3

Router settings the robot can't use

The manuals in the table list 2.4 GHz Wi-Fi. Any of these can block the join: a hidden network name, a mistyped password, MAC filtering or a whitelist, a web login page, or a VPN on the phone. Dreame suggests testing with a name and password made only of letters and numbers.

4

WPA3 on a model Dreame lists as WPA2

Dreame's connection guide names the L40 Ultra AE, L10s Pro Ultra Heat and L20 Ultra Complete as WPA2 models without current WPA3 support. The guide doesn't say whether the other models support WPA3.

5

Internet, DNS or server stage

Sometimes the robot joins the router and setup still fails at the server stage. Dreame lists missing internet and DNS that isn't resolving as possible reasons, so check those next. Stopping at this stage doesn't clear the robot, and it doesn't condemn it either.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Match the app and controls to your model

Read the exact model name on the robot's label and find it in the table. Install the app its manual lists. If you're unsure, the robot's QR code and your regional version take priority. Turn on Bluetooth and give the app location access before you start.

Put the robot into pairing mode

Switch the robot on and keep the phone next to it with Wi-Fi enabled. Use the control the table gives for your model, then wait for the signs its manual describes. Set it up from one phone only. Two phones working on the same robot can stop it being found.

Hand the phone over and wait

When the app sends you to Wi-Fi settings, join the robot's hotspot. Stay on it until the robot gives its voice prompt. Then go back to the app and leave the progress screen alone until it finishes.

Check what the router offers the robot

Pick the 2.4 GHz network and type the password again. If the router uses one name for both bands, giving 2.4 GHz its own name during setup is a fair test. Keep the network name visible, and check MAC filtering or whitelists. Turn off VPN or proxy apps on the phone, and avoid networks that ask for a web login.

Source: Dreame Support: FAQ for Failed to Connect Network/Wifi (Error 1 to 5)

Separate the server stage

If the robot joins the router but setup fails at the server step, check two things: the phone and robot are on the same 2.4 GHz network, and that network has internet. Dreame mentions a public DNS server as a test. You don't need to keep that change.

Source: Dreame Support: FAQ for Failed to Connect Network/Wifi (Error 1 to 5)

Try a phone hotspot, then contact support

Start a 2.4 GHz hotspot on a second phone, connect the setup phone to it and pair the robot to that network. If it works, look again at the home network. If it fails, Dreame says a hardware issue is possible, though the test doesn't confirm one. Record the whole attempt, then note the SN and your app account ID for support.

IF IT STILL FAILS

IF
The app never finds the robot or its hotspot
→ First make sure no other phone is in the middle of setting it up. Then follow the prompt on the app's Device Reset page to turn the robot's hotspot back on. Keep the phone close with Wi-Fi on, and look for the hotspot name the app describes. Source: Dreame Support: FAQ for Failed to Connect Network/Wifi (Error 1 to 5)
IF
The phone joins the hotspot, then the app stalls
→ In the phone's settings, allow Dreamehome location and local network access. Update the app and start again from add device. A missing permission can stop this stage by itself, so a stall here doesn't point to a hardware fault on its own. Source: Dreame Support: FAQ for Failed to Connect Network/Wifi (Error 1 to 5)
IF
It worked before and now shows offline
→ Check that the robot has power, look at its Wi-Fi light and restart the router. Then add the device again in the app. After a router change, pair it using your model's control from the table. Dreame doesn't promise that maps survive re-pairing on every model, and a factory reset does erase them. Source: Dreame Support: Robot vacuum and mop device offline (Step 1 to 4)
IF
An L20 Ultra drops offline now and then
→ Dreame's L20 article lists three situations: the robot is switched off, coverage where it cleans is weak or unstable, or the Wi-Fi has no internet. It also says a clean that is already running can carry on while offline. That note is written for the L20 Ultra only, and it wasn't checked for other models.

WHEN TO STOP

STOP HERE

Work through your model's pairing route before you consider a factory reset. Dreame warns that a reset erases data, including maps, and the controls in the table are separate functions. On an L40 Ultra AE, use the app's add-device route. Its manual describes the 3-second Reset button as a factory reset in one place and as a Wi-Fi disconnect in another. If the hotspot comparison also fails, stop changing router settings. Send support the SN, your app account ID and a full screen recording of the attempt.

FIELD NOTES

WHAT THE OFFICIAL DOCS LEAVE OUT — AND WHAT OWNERS REPORT

Start with the model name, because Dreame's pairing instructions change from manual to manual. The original D9, L10 Pro, Z10 Pro and W10 use Spot Clean + Dock. The F9, D10 Plus, D10s, L10 Prime and L10s Ultra use Power + Dock. The Wi-Fi pages for the L20 Ultra, L10s Pro Ultra Heat, X30 Ultra, X40 Ultra, L40 Ultra and X50 Ultra list no button pair and send you back through the app. Family names can mislead. The L40 Ultra AE manual is not the L40 Ultra manual, and some notices name Complete versions on their own.

The Wi-Fi light gives a rough location. The manuals checked here generally describe a slow flash as waiting for setup, a fast flash as connecting and a steady light as connected. A fast flash only tells you the robot is still trying. It doesn't prove the signal is weak. The dock and status lights are separate indicators.

Where setup stops decides what you check next. If the robot never shows up, go back to pairing mode, the app and phone permissions. A hang after the hotspot handover sends you to the phone first. A failed router join brings you back to the band, password and router rules. A stop at the server stage calls for an internet and DNS check, though it doesn't rule the robot out. A router that looks fine doesn't clear the robot's hardware, and a failed hotspot test doesn't condemn it.

Keep pairing and factory reset apart. Dreame warns that a factory reset erases data and maps, and none of the sources checked promise that re-pairing keeps maps or schedules on every model. On security, Dreame names the L40 Ultra AE, L10s Pro Ultra Heat and L20 Ultra Complete as WPA2 models that don't currently support WPA3. For every other model here, WPA3 support is simply unknown.

FAQ · REAL QUESTIONS

How do I reconnect my Dreame to Wi-Fi?

Put the robot back into pairing mode with the control its manual lists, shown in the table. Then add it again in the app on a 2.4 GHz network with location and Bluetooth on. Nine checked manuals use a two-button hold; six use the app's add-device and QR steps.

Why won't my Dreame connect to Wi-Fi?

Look at where setup stops. If the robot is never found, check pairing mode and use one phone. If it stalls after the hotspot, check app permissions first. A failed router join points to band, password and router rules; a server-stage failure, to internet and DNS checks.

Source: Dreame Support: FAQ for Failed to Connect Network/Wifi (Error 1 to 5)

Which app do I use for my Dreame, Mi Home or Dreamehome?

Use the app your manual lists. In the manuals checked here, the F9, original D9, L10 Pro, Z10 Pro and W10 use Mi Home/Xiaomi Home. The D10 Plus works with Dreamehome or Mi Home, and the rest use Dreamehome. The robot's QR code and your regional version take priority.

Source: Dreame Support: How to connect your robot vacuum and mop to Wi-Fi (Add Device; Friendly Reminder)

How do I connect a Dreame to a new Wi-Fi network?

You need to pair it again. Put it in pairing mode with your model's control, then add it in the app while your phone is on the new router's 2.4 GHz network. Dreame doesn't promise that maps or schedules carry over on every model.

Source: Dreame Support: Robot vacuum and mop device offline (Step 1 to 4)

How do I get my Dreame back online?

Check the robot has power, look at its Wi-Fi light, then restart the router. If the app still shows it offline, add the device again. If pairing fails at that point, work through the stages above and try the hotspot comparison before you contact support.

Source: Dreame Support: Robot vacuum and mop device offline (Step 1 to 4)

Does my Dreame support WPA3?

Dreame names the L40 Ultra AE, L10s Pro Ultra Heat and L20 Ultra Complete as WPA2 models without current WPA3 support, so use WPA2 with those. For the other models, the guidance checked here doesn't say either way.
