I almost hesitate posting this because its very odd, but want to make sure nobody else has seen it…
I had a RB532v5 go dead it appeared at a tower site a couple of days ago. After being off line for about 3 hours the wlan reconnected out of the blue while I was driving there but when I arrived at tower site and logged into the radio it was still running, associated to the other tower (wasn’t when I left to go there) and I opened the ip/routes and there were none. I looked at OSPF and all the settings were reset to default which is why nothing could get to it - once it had reconnected wirelessly.
I just replaced it with new gear I had programmed when I arrived, it was a long drive 
Any ideas as to what could have happened? Anyone seen this behavior?
