SRR60 wired devices and satellites constantly dropping connection

Our wired satellites are dropping the connection to the router. Also our network printer that's plugged directly into the router sitting near it, is also dropping off the network. Wi-Fi from the router is not affected whatsoever, It is consistently on and working(satellite APs go down).
So we will lose connection to the hardwired printer Along with the satellites throughout the facility go down.
When I log into a satellite access point, I'm able to see that it does not have a connection to the router at all. It's almost as if someone has unplugged the Ethernet cable.
