Wow very interesting hypothesis since it happened right after a lightning storm with heavy rain. Trouble is I shut off all six backhauls and started turning them on one by one until I had a "IP conflict" warning then turned that one off, the IP conflict happened again, yes I did arp -d to clear the bouncing out of it but then it happened on a different tower, I just can't seem to find it and yes we're way too large to be bridged, that was our summer project to become routed but that doesn't help today. It's a great idea but I have 54 AP's so I don't know where to start.
