Orbi 770 – WiFi Drops Every Hour

At the beginning of the year, I posted in this forum about hourly interruptions with my ORBI770 mesh system. At the time, other users were experiencing similar problems, and I worked with Netgear Support to identify and solve the issue. Unfortunately, the past 8–9 months have been unsuccessful...

Recently, I have read less from others with the same problem. Perhaps the problem has been solved for others, or they have switched to a different vendor.

Unfortunately, the problem has not yet been solved for me, and I am still regularly writing to Netgear Support and uploading logs. Unfortunately, without a qualified answer or solution.

Over the past few days, I have tried a number of troubleshooting measures, such as:

• Adjusting NTP to a different NTP server
• Deactivating DHCP on ORBI and providing it on a Linux server
• Disabling private MAC addresses on all Apple devices
• and so on ...

Unfortunately, none of this has been successful and I still experience hourly interruptions. I have now provided ChatGPT with the information and uploaded the log files, and received the response in the pdf attached to this post. I am aware that ChatGPT is often wrong and often just writes nonsense (e.g. firmware version, which are not available). But maybe it points in the right direction, since Netgear Support doesn't feel responsible for simply analysing log files.

I also installed uptime-kuma on my computer and pinged various devices over the last few hours. I can only set the pings to every 20 seconds, so it doesn't catch all the hourly interruptions. However, you can see the pattern. 
In the first three screenshots, I marked the interruptions at xx:03 / xx:04 in red. 
In the last three screenshots, I ping the router and satellites (all wired). I find it interesting that the satellites respond faster than the router. But perhaps that is normal behaviour.

Am I alone, or do others still have the same problem?

Thanks.
