Is your router broadcasting a 2.4 GHz network?

All Dyson connected machines use WiFi to connect to the internet. There are two frequency bands commonly used for a WiFi communication: 2.4 and 5 GHz.

Dyson connected machines only use 2.4 GHz band. Many modern routers support both bands - this is known as a dual band router.

Your router will need to be broadcasting a 2.4GHz network for your appliance to connect.

How to check if your router is a dual band router

If your router is dual band, this information can often be found in the Router user guide or on a sticker located on the router. If you are unable to find this information or unsure we recommend contacting your internet service provider who will be able to supply you with this information.

Often the manual or website will have instructions for how to set it to broadcast on both 2.4 and 5 GHz bands. This will allow you to broadcast the right network to allow you to connect.

The appliance will only connect to the 2.4 GHz network. Your phone will need to be connected to the same network as the appliance for initial set up.

Supported WiFi protocols:

IEEE802.11b (Not recommended)

IEEE802.11g

IEEE802.11n (Support only for 2.4GHz

To switch your router from 5GHz to 2.4GHz, please refer to your routers user guide, or visit the manufacturer’s website. Please note, you will need to check that any other devices you have connected to your router will not be affected before changing this.

Could there be interference from other devices?

Turn off any device that may cause interference at 2.4 GHz. E.g. cordless phones, baby monitors, microwaves, Bluetooth devices, wireless video equipment.

Has this resolved the problem?

Has the WiFi mode timed out?

Your appliance will remain discoverable for 30 minutes. Press and hold the power button on your machine for 5 seconds to retry.

Temporarily disable any parental control settings whilst setting up the appliance on the network.

Check your WiFi security settings

Dyson purifiers can only connect with WPA and WPA2 (WiFi Protected Access) security protocols.

Disconnect a device connected to your network by disabling WiFi or switching it off.

Try to connect your appliance to the network again.

If this works, contact your router manufacturer or Internet Service Provider to increase the allowed number of simultaneous connections to the network.

Is the SSID (network name) hidden?

The appliance cannot currently attach to a hidden SSID network. To use the appliance, unhide your SSID and attach your appliance.

The appliance cannot connect to networks that have web portals that require an additional password to connect. For example hotel, airport or office networks.

Is MAC address filtering switched on?

This stops unknown devices connecting to your WiFi connection. If you have this switched on, you will need to add the MAC address from your machines rating plate to your routers list of approved devices.

Is Wi-Fi privacy 'enabled'?

This stops devices talking to each other – you will need to disable WiFi privacy for the appliance to connect.

Are parental controls enabled?

Temporarily disable any parental control settings whilst setting up the appliance on the network.

Has this resolved the problem?

What connection caused error?

Did the error occured whilst the mobile device was connected to:

  • Same WiFi network as the appliance
  • A different WiFi network
  • A mobile network such as 3G/4G

WiFi troubleshooting

Please run through the following checks.

Is your router broadcasting a 2.4GHz network?

All Dyson connected machines use WiFi to connect to the internet. There are two frequency bands commonly used for a WiFi communication: 2.4 and 5 GHz.

Dyson connected machines only use the 2.4 GHz band. Many modern routes support both bands - this is known as a dual band router.

Your router will need to be broadcasting a 2.4GHz network for your purifier to connect.

How to check if your router is a dual band router

If your router is dual band, this information can often be found in the router user guide or on a sticker located on the router.

If you are unable to find this information, or are unsure about how to, we recommend contacting your internet service provider who will be able to supply you with this information.

Often the manual or website will have instructions for how to set it to broadcast on both 2.4 and 5 GHz bands. This will allow you to broadcast the right network to allow you to connect.

The purifier will only connect to the 2.4GHz network. Your phone will need to be connected to the same network as the purifier for initial set up.

Supported WiFi protocols:

  • IEEE802.11b (not recommended)
  • IEEE802.11g
  • IEEE802.11n (support only for 2.4GHz)

To switch your router from 5GHz to 2.4GHz, please refer to your routers user guide, or visit the manufacturer's website.

Please note, you will need to check that any other devices you have connected to your router will not be affected before changing this.

Could there be interference from other devices?

Turn off any device that may cause interference at 2.4 GHz. E.g. cordless phones, baby monitors, microwaves, Bluetooth devices, wireless video equipment.

Has this resolved the problem?

Has the Wi-Fi mode timed out?

Your purifier will remain discoverable for 30 minutes. Press and hold the power button on your machine for 5 seconds to retry.

Is the Wi-Fi connection working with other devices?

Try to connect to the WiFi network with another device such as your phone or tablet.

If other devices cannot connect then check that the appliance is not too far away and is within range of the router. Contact your Internet Service Provider or router manufacturer for further troubleshooting.

Are there too many devices connected to your network?

The number of simultaneous connections to the network may be limited by your router manufacturer or Internet Service Provider.

Disconnect a device connected to your network by disabling WiFi or switching it off.

  • Try to connect your purifier to the network again.
  • If this works, contact your router manufacturer or Internet Service Provider to increase the allowed number of simultaneous connections to the network.

Is the SSID (network name) hidden?

  • The purifier cannot currently attach to a hidden SSID network. To use the purifier, unhide your SSID and attach your purifier.
  • The purifier cannot connect to networks that have web portals that require an additional password to connect. For example hotel, airport or office networks.

Is MAC address filtering switched on?

This stops unknown devices connecting to your WiFi connection. If you have this switched on, you will need to add the MAC address from your machines rating plate to your routers list of approved devices.

Is Wi-Fi privacy 'enabled'?

This stops devices talking to each other – you will need to disable WiFi privacy for the purifier to connect.

Are parental controls enabled?

Temporarily disable any parental control settings whilst setting up the purifier on the network.

Has this resolved the problem?

WiFi diagnostic checks

Check that your purifier's WiFi light is illuminated. To turn it on again, press and hold the 'Standby ON/OFF' button until the WiFi light begins flashing.

Check that your smartphone or tablet is within network range of your purifier.

Has checking the WiFi settings resolved the problem?

Input the correct password

You will need to input your WiFi password to set up the connectivity options. The serial number and WiFi information can be found in the following locations:

On the front of the instruction manual.

On the remote control packaging.

On a removable sticker on the front of the purifier.

On your purifier, located underneath the filter.

NB: The purifier's password is made up of numbers and lower case letters only, so '0' is definitely the number zero. The number '1' and the letter 'l' (L) may look similar, as may the letters 'j' (J) and 'i' (I).

Has checking the passcode resolved the problem?

Hold the ON/OFF switch

The WiFi light lasts for 30 minutes, if you don't manage to connect in time, simply press and hold the 'Standby ON/OFF' button for 5 seconds until the green WiFi light starts flashing and you have another 30 minute window.

Once you have done this, run through the connection process again.

Continuous monitoring

The continuous monitoring option is used for air quality, temperature and humidity data to be relayed to the machine and app at all times, even when you have turned the purifier off. The sensors have small fans that maintain airflow for continuous monitoring, but this should not cause any audible noise interference.

There may be instances when the display shows green, indicating high air quality, but the fan speed is still high.

This is due to the machine constantly seeking to maintain a good air quality, and in scenarios such as rooms with leaky windows, the machine must work harder to maintain a good air quality.

This will only happen when the machine is set on auto. To turn off Auto mode, please select Manual mode, either using the remote control or on the app.

Image showing the remote auto mode button.

Please check the following on the app:

Swipe up to reveal the setting tab and tap to open options.

Swipe down to find the continuous monitoring option and tap to open.

Turn OFF the 'Collect data when in standby' option. (The icon will turn grey when turned off). Save the change by pressing 'Done' at the top right of the page.

Continuous monitoring can now also be turned on/off by pressing the 'Auto' button on the remote control for five seconds.
