My hub has been running fine for a long time. A few days ago I started getting alerts that it has disconnected and reconnected. Those haven’t gone away. I power cycled the hub and it didn’t fix it.
Nothing else in my house is having wifi issues. Why else might be causing this?
One of mine did earlier today & hasn’t come back yet. It’s been almost five hours so far. Since it is in another location 1500 miles away, I’m going to have to wait for it: either comes back on its own or my daily auto-reboot after midnight should do it…
Fingers crossed 
I have been having the same problem and can’t find a solution anywhere. I confirmed that no internet connectivity issues. Anyone solve this persistent problem?
I’m having the same issues the last 2 days. Hub disconnects for about 2 minutes or so then reconnects. No internet or WiFi issues occurring other than with SmartThings. Has been disconnecting multiple times a day. Any thoughts. Anyone else having this issue.
