Dyson Pure Hot+Cool™ Link fan keeps dropping off network

I have recently installed a Netgear RBR50 Orbi Router and RBS50 Orbi Satellite to replace my (D8500) X8 Nighthawk + (EX7500) X4S Extender.

 

Everything has been solid except for one device; a Dyson Pure Hot+Cool™ Link fan (https://www.dyson.com.au/fans-and-heaters/purifiers/dyson-pure-hot-cool-link-evo)

 

The Dyson fan, after a reboot, will connect fine and stay on the network for maybe a few hours and then 'disappears'. A reboot and the same things happens.

 

I also see a huge number of DNS requests to broker6.cp.dyson.com - one request every 10 seconds endlessly.

 

The Dyson fan is on the most recent software version from Dyson - 21.04.03.

My Orbi's are on v2.3.1.60

 

I have tried disabling:

  • Enable Implicit BEAMFORMING - Boosts WiFi speed, reliability, & range for all mobile devices
  • Enable MU-MIMO
  • Enable Fast Roaming

in the Advanced Setup -> Wireless Settings to see if changed the outcome but saw no difference in behaiour over a week.

 

Any thoughts/suggestions?

 

TIA.

Have you tried giving it a static IP address? Or reserved IP address?

Current Setup: CM2000-> RBK750-> GS716v2-> RAXE500-> Pi-hole->

I can certainly give that a try!

I have a Dyson Pure fan and it has remained solidly connected using the Orbi default settings. Maybe consider resetting the Dyson and set it up again.

Please describe 'disappears'.  i.e. does not show on the Attached Devices display, but can still be controlled?  Is still on the display, but cannot be controlled?

The DNS queries are showing up how?  (Wireshark capture?)

I love my Orbi.

By 'disappears' I mean stops being visible to the smartphone app, doesn't respond to subnet IP scan from my PC using NetScan, doesn't display in the Orbi connected devices list. The Dyson fan itself seems to believe it is on the network as it shows a solid white WiFi indicator which indicates network connection.

The DNS queries are from an internal DNS I run (Adguard Home) so I can see everything all of my devices are querying.

Did you try a factory reset on the Dyson (I think you hold the power buton for 20 seconds)? I assume you don't have a double NAT issue by running two routers with NAT enabled?

I am having the same issue and even stuck on pairing with Dyson Link app. The pairing process is timeout and Dyson is showing solid white WiFi light on the device. I realise in the log Dyson is keep trying connection. May I know if anyone encounters same issue? I am using an Orbi mesh system also.

I don’t have any issues connecting to my Dyson fan using the App on my iPad with the Orbi system. Make sure you are not running the Orbi with another router, as double NAT will give you lots of issues.

Sorry, I should've mentioned at the top that I'm using the Orbi setup in AP Mode so no double-NATing involved.
