Orbi Satellite not handing out wired DHCP Addresses

Hey there,

My Orbi router is handing out wired and wireless IPs via DHCP just fine (and it is configured as the DHCP server). The one satellite I have is very merrily handing out wirless IPs, but it won't hand out wired addresses any more.

If I manually configure an IP to a wired connection it doesn't work either. Anyone have any experience with an issue like this? I've reset the satellite (I think! It seems to rejoin automatically, so I can't be sure I actually successfully factory reset it).
