I found a thread from several years ago about this issue. I’ve noticed it with balance 20x and a Bone router to this day. I’m curious if this will ever be fixed. It throws a wrench in some of my network troubleshooting…
The issue I’m finding is that sometimes devices that are online and active either don’t show at all or are shown in grey in the Client List tab of the UI of the router. I just rebooted a dual ethernet server (where both are currently just connected to switch that is on the a port of a Bone. One of these ethernet connections shows up fine on the Peplink and the other is grey. Both are set to DHCP so they are getting their IPs from the Peplink. I can ping the grey one from other devices on the network. It’s active.
