Orbi CBR40 Dropping Internet Connection Multiple Times Throughout the Day
Router/Modem combo randomly loses internet connection 2-3 times a day. I've had it for over 4 years and it has worked fine until a couple weeks ago. It randomly loses connection to the internet throughout the day. I thought it might be our Roku Ultra that we use for streaming but I unplugged it and used the TV to stream and experienced two drops today. Reseting the CBR40 fixes the problem and everything works fine for a while until it loses internet again and has to be reset. I've checked connections, reset the modem through my ISP, updated to the latest firmware, and repositioned the device and continue to have the same problem. Please help!

While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.
You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:
Cable Modems & Routers
I will ask the Netgear moderator to move your message.
In the meantime you could visit the support pages:
Support | NETGEAR
Feed in your model number and check the documentation for your hardware.
Check for various troubleshooting tips.
You may have done this already. I can't tell from your message.
I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.Here's the event log from the most recent drop. Again any help would be appreciated. I really don't want to have to buy a new router/modem right now but can't continue resetting and waiting several minutes for the modem to reboot 2-3 times daily. Also, I have two satelites connected wirelessly. One is in my garage and other in my kitchen. Each is 20-30 feet from the CBR40 and they are probably 40ish feet away from each other forming a triangle. The kitchen satellite is an RBS20 and garage one is an RBS50. I originally had just the RBS20 but added the RBS50 last summer and have been using this setup for nearly a year without issue.

These messages are all over the event log for the last 8 days (only shows last 8 days of events). Another one that shows up periodically is

Is that the log from the router? I don't recognise the format.
You are on a cable Internet service. There are people around here who are much better informed on that front. They can help you to unravel the connection data. That is often a source of problems. Your ISP may say everything is fine at its end, but a lot can happen between the ISP and your device.
That is why I suggested getting your message out of the router zone and into an area where people understand cable modems.
With luck someone like plemans will see your message and step in.
That the modem/router worked for four years certainly suggests that there is something happening outside the device.
You say that you reset the modem through the ISP. Have you done a local factory reset?
A full screen snip of the event log and the cable connections page helps the most for checking the line.
But a few tips for troubleshooting cable coax lines.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, bad/old/cheap connectors, or corroded connections. Replace them if you do.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.
