Deco M9 Plus satellites blinking red but seem to be connected and online
I got the Deco M9 Plus three pack about 2-3 weeks ago and it seems to work great. But I noticed last night that my satellites were both blinking red. According to the instructions, that means they've lost connection to the main Deco. However, according to the Deco app, they are both online and both have devices connected to them. Everything seems to work well. Not sure whether I need to do anything or not.
Here's what I see in the app:
Also, on a side note, when I check for firmware updates in the app, it says I have the latest version. But the TP-Link site shows a newer version (1.5.5) is available. Which is correct and should I upgrade?
