The Nest Connect range extender doesn't let you or even mention what Security mode it uses to communicate with the router. That would be nice to know. Any other undocumented restrictions we are told about. Will it work on 5 Ghz? Simply asking. Is Google working on making this more persistant and robust? Then I can move on to he lock.</P> Sun, 31 Jul 2022 15:08:04 GMT https://www.googlenestcommunity.com/t5/Security/Google-Nest-app-doesn-t-communicate-with-the-Connect-Device/m-p/209992#M2465 Tetra 2022-07-31T15:08:04Z https://www.googlenestcommunity.com/t5/Security/Google-Nest-app-doesn-t-communicate-with-the-Connect-Device/m-p/210027#M2466 <P>Just dawned on me.......is the Nest connect device compatible with a mesh WiFi network?
