Chromebook won't update and disconnects on home wifi

[mrstrong]

Got a Chromebook which when you check for updates says its up to date (on version 74 (been on the shelf for a while!))

 

Another one exact same model on version 80 so I know it will take later versions but how to force it

to update ?

 

Also in school chromebooks auto connect to school wifi on boot / wake from sleep but they don't

seem to do this on home wifi: you have to manually go in and connect it again which is a royal pain in the #!r5e

 

Is there a setting some where to fix this ?

well 24 hours later and chromebook just decided to update to v81.

Guess theres no way to force this as yesterday it was adamant 74 was up to date !

 

Also unchecked this, to see if fixes wi-fi

Device management - Networks - General Settings

Only allow managed networks to auto-connect
