Model AC1900 Router - no wifi after power outage (internet ok)

I have a router that is just less than a year old (AC 1900).  Last Friday there was a power outage in the neighborhood, a blown transformer.  In tandem, we received notices that there was an internet outage.  After internet was restored several hours later, my computer (hard wired) eventually had internet restored but our devices did not get wifi back (we have a Roku smart tv, two iphones and a macbook).  

I have had multiple calls with advanced technical support of my internet provider and they say everything looks fine.  I have done all of the basics (I've re-set the router about 10 times now).  On the phones, we've done the "forget this wifi" and then re login.  (Yes, I can see the router on my phone but it says "no internet connection").  I guess I've come to the conclusion that my router was somehow damaged by whatever happened?

Anything else I can do?

Thank you.
