We have occasional power outages of varying length, none very long, none only a flicker.
My router survives some of these power losses, but on others it goes brain dead and instead of remembering ANY of my personalized setup comes back with the basic factory defaults it left the factory with causing everything on my network reliant on it to be useless (wifi security cameras, doorbell, thermostate, etc. etc. etc) That's because all the other devices do remember in their non-volatile memory and retry what I set my router up for. Of course I did apply (save) these inputs and they are remembered some of the time, but it's not faithfully consistent, I can't rely on it. I have installed the latest firmware update, since it didn't always have this problem I can't help but wonder if it came in with one of the firmware updates?
When I am out of state I cant get home to re-enter all the wireless and other personalizations to get everthing working again, and BTW, this router's backup does not store everything I enter/input into the setup making the backup only a partial time saver, and that's always been the case.
This is the first Netgear router I have ever owned that stores basic setup information in "volatile" RAM memory instead of saving it in non-volitile memory, and as I discribed it's also variable whether after the outage it's going to come back with "hello" or "duh?"
Re: Nighthawk R7900P
I recommend getting a UPS and connecting the router and modem to it. NETGEAR's firmware is not always relaible and has many problems
