Ethernet backhaul after point to point long distance wireless bridge

So here is the long story. I went home and somehow the barn satellite had connected with wireless backhaul to the router even with the distance of barn to house. When I looked at connected devices on the barn satellite, it showed both point to point hardware IPs and MAC addresses connected wired to it. Since they were recognized I just did a reboot of everything and the next time it came on it worked as a wired backhauled satellite no problem. I have no clue what the issue was but the ole unplug it and plug it back in seemed to change things. Thanks for all suggestions.
