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 throug...
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
Critical(3) No Ranging Response received - T3 time-out
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.
- Modem isn't exactly where it comes into the house but isn't far from it. It's connected with a high quality coax that's less than 6 ft long. There is nothing in the line from the wall to the modem other than the cable. Also, it has been set up this exact way since we bought the house in Nov. 2019 and has had no problems. ISP is COX cable and I get 250 down when everything is functioning properly. I tried swapping my 2.4GHz channel as well. It was set to auto and using channel 3. I switched it to channel 6. Would have done 11 but my neighbors wifi appears to be on 11. 5GHz is on channel 48.
Your signal is actually a bit hot (high).
Try putting a good quality double or triple splitter in line to cut the power level down.
You should be between -7.5dbmv to 7.5dbmv. You're a ways above that.
- Ok, I have a 2 way splitter coming tomorrow that I'll put in the line. Strange that too much power would be a problem. Also, I assume the power has been the same for the last 2.5 years with no problem. I'll put the splitter in tomorrow and see what I get.
