R7800 no internet after power outage
I have been experiencing some issues with my R7800 for a while now. If the power goes out for any duration, my router and cable modem both come back up, but my router never recovers the internet connection. If I go into the router settings and tell it to detect, it recovers. If I reset the router (button on back) it recovers. Otherwise, it will sit for days after an outage and never pick the internet back up. I have read posts about time outs and such. This used to work until some version of firmware. It seems like the router simply times out trying to detect internet until it is forced. I have had my cable company replace the cable modem. It was an Arris and now is a Ubee. I have called them and there is nothing on their end to resolve this. I have tried various settings on the router to no avail. My alarm system depends on this connection to some degree and when I am away and this happens, I have to send someone over and have them reset the router to get things back online. Is there not some way to set the router to redetect or retry?

That's because your router comes up faster than your modem does. When this happens, the router seeks an IP address but the modem can't provide one since it's still booting up. I don't really have a solution for this
This used to work perfectly. I think it started with the .68 firmware. I have been tempted to go back on firmware to find out exactly when, but that leaves me with vulnerabilities. One would think the firmware could add some sort of timeout/retry value. All I have to do is go into the router and click on the "Error..Not connected" link and it redetects and fixes itself. I can also reset the router. None of this can be done remotely. Seems like Netgear could fix this.

It might be possible to do something local automatically, however.
If you had a computer on your LAN which reliably started when power
returned, then it might use a program like Wget to prod the router
repeatedly until communication with the outside world returned. A (very
cheap) Raspberry Pi might serve, for example. But investing in a better
router might be a better use of resources (money and time).> [...] Seems like Netgear could fix this.
Many things are possible, but, without a formal complaint from a
paid-support customer, I wouldn't hold my breath. (Even with, ...)
