I have a second Rb951 routers going autistic in 2 months after a blackout… reset every 10 seconds, no response with netinstall, no reactions to reset button, no wifi… completely dead to the world. The act LED doesn’t even go on… I’m going to replace also this one…
Maybe it wasn’t only Blackout, but some sudden increase of voltage (aka. Power Surge)
If the Utility’s aren’t Stable invest in a Uninterruptible Power Source (UPS)
or some industrial Power-Supply’s capable of handling bad Input-Current.
