A tech came out just over a week ago. Removed a splitter from when I still used cable tv. He said everything else on their end was good. And since I had just reset my modem I didn’t have any real data from logs to show.
Since the tech came out there have still been daily drops requiring a modem reset. Here is today's event log after making the recommended changes last night. Only one drop today but that was around 1pm and I couldn't do a over the air reset using my ISP app so my connected devices were down which is my main concern. So right now not sure what else I should try. Netgear is not willing to ship me my RMA with standard shipping and they are adamant I pay for advanced shipping which seems like complete BS.
"I really understand your situation but as per company policy If you choose standard delivery you need to send faulty device first .
If you need a replacement device first means you need to choose advance delivery option (which is payable )"
Event log shows criticals that timing sync is being lost so this is something on the ISP line or signal that's not right. Power levels are at the high limit but should ok. However you have way too many correct and uncorrectables still. Those should be zero's. This shows there is problems on the ISP line.
Try for an RMA and see if a different unit exhibits the same problem. If it does then this is an ISP line problem the ISP needs to correct.
I have the Cox technician coming today and I already mentioned the correctables/uncorrectables and errors to him. He said if the lines to the house are showing fine then he is going to say the modem is the issue and since it isn't their equipment nothing they can do. That was over the phone though so I guess I will see what occurs when he arrives. I will update later today but fair bet is they are going to blame my modem and make it not their problem.
Of course. One thing you can do, ask for a loaner modem and test there modem for a bit.
Those Correct and Uncorrectables is the CBR trying to do it's own corrections to the signal coming from the ISP. IF the signal and cabling and connections are ALL good, technically, those values should all be zeros.
Though not same model modem I have online but example of how NG modems should look: CM1200
The last two values are my Correct and Un-correctables. I had my CBR750 online a few months back. Same values though I did have a few items that had some uncorrectables. I found that my coax cable connector on the back of the CBR was not fully seated. Re-seated the connector and the values were all zeros. Mostly a cable and connector or line splitter can cause these issues here.
Well I can say that this the ISP didn't do anything which will make my situation better. Still having these errors show after the tech left. My correctable/uncorrectables I don't even know how they show what they do now. He cut the line to the house and put a new end on and switched out the coax cable I purchased as he said that was causing more ingress than the cable he put on. I will post the correctable next. The tech scheduled a follow up for this Tuesday so I am certain I will need to reboot several times until then.
Criticals in the events log that the ISP needs to review.
ANy chance you have a friend or family member that has cable ISP that you could take the CBR to test out there by chance. Would be interesting to see if problem followed the CBR or not.
I showed the tech that and discussed all that stuff. He changed my coax to their's, cut the line and put a new terminal on, and scheduled a follow up this Tuesday. At this point nothing I can do other than try to get a different modem through the ISP to see if that changes anything and continue to process the RMA which Netgear is giving me challenges with. The correctables/uncorrectables numbers are getting higher so I don't know. I have done what I can do.
