After 4 day power outage two cameras will not connect to our network

I need help getting two indoor/outdoor cameras to connect to the network. We had straight lines winds go thru Western Pennsylvania last Tuesday which caused massive power outages everywhere. Our power came on last night (Saturday) but two cameras keep blinking amber. Neither camera gives me a preview. Sometimes the cameras show up as connected devices. I need tech specific information. I’ve reboot the router manually and thru the Xfinity app but it was no help. One camera was unplugged and plugged in but it didn’t help. The other camera is over the patio door outside and I can’t even reach the outlet.
