I set up a new X20 mesh network a few weeks ago and it was working fine until this morning. I got a notice that security database had been updated, and since then, my decos are constantly disconnecting from each other today. I've rebooted all of them and checked that they're running the latest firmware. Still experiencing the problem. Help! These are new routers and this is completely unacceptable, especially in a season like this with COVID-19 where I'm relying on my wifi to work.
