rbr50v2 loses internet periodically after install of v 2.7.3.22

I just installed firmware version 2.7.3.22.  Since then, my router stays connected to the internet for about 1/2 hour and then drops the internet.  I have to restart the router to get the internet back.  It is dropped again in 1/2 hour.  And repeat.  The following is the log.  Note that the router internet service was down overnight.  I redownloaded and manually reinstalled the same firmware version about 8:15 this morning.  I had reset the router to get internet service about 08:00.  The fact that I got those DoS Attacks makes no sense, since the internet service was down overnight.

I'd do a whois lookup on those IP addresses that are incoming on the WAN side and see where there coming from.

 

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

I would avoid posting private device MAC addresses in public forums as well.

Re: rbr50v2 loses internet periodically after install of v 2.7.3.22

I had to pay for a subscription ticket and worked about 6 hours after to find the solution.  The problem was the old firmware and the new firmware were not compatible, so all the inherited router settings where just random data to the new firmware.  There certainly should have been a warning that such a situation existed, and the software installer should have caught it.  I consider this the worst possible outcome of support a technical company can have:  releasing incompatible firmware and then charging an arm and a leg to tell the customer so... And that the solution was a hard reset and start the entire house configuration from scratch.  One key issue for me is that in the old firmware I could set 2.4 and 5 as separate SSIDs, in the new software the SSID is the same.  Another issue was the satellite had some problems.  So a 3 day bummer for failure of Netgear support and my out of pocket cost.

What did they mean my saying that old and new FW were not compatible?

Orbi has never been able to separate SSIDs nor is it supported by NG.

They didn't say it was incompatible.  They just said the setup I had was incompatible.  I couldn't back it up and then use it once the hard reset was done. Is there a difference?  Maybe politically, but not practically.  And the old setup doesn't lie.  And my entire house SSID setup doesn't lie.  I had a 2.4 and a 5 SSID.  I used both.  So "Never" isn't true.  The Orbi's were purchased in 2020.  They said all the attack messages were artifacts generated by the firmware and had nothing to do with the internet itself.  The modem is a Arris provided by Spectrum. Anyway the problem is solved, just irks me that I had to pay for them to fix a problem that was Netgear's.  

 

I've asked to have the macs removed through the report an improper entry, but it hasn't been done and I can see no way to edit my own post.  Do you know of a way?
