Connection Drops with Netgear cg3000d Gateway

I am having internet connection drops with the wireless devices I have in the home. It happens between 10 to 15 times. a technician has been out and replaced coax, connectors and the splitter that terms into my gateway. I checked the error history on the gateway in this iw what I am seeing. I did see other posts but I was not sure if it was the same conclusion.  Perhaps you can help.

Hmm. The signal levels to the modem look good, and the most recent disconnect or timeout event in the modem log is 6/27, so it's probably not an issue on the cable side and more likely an issue on the wireless side.

Our main focus is the wired side of the connection, but the modem manufacturer provides some tips on improving wireless range.

Ok, but how do you explain the T4 and T3 timeouts that relate to the comm between the modem and the cmts? In doing some research it looks like it has to time out and re-initialize for some reason. It sounds like this would cause a drop in connection. And on the Sync timing synchronization failure, that appears to be related to upstream and downstream communication issues...maybe physical. These errors are fairly consistent after the T4 timeout error message. how do you explain these types of errors? Or am I not understanding something?

Those would have been related to the cable signal, but checking it again today those still have not incremented anytime recently. The last T3, T4, or fail-to-acquire-sync is 6/27. This is the modem log our diagnostic page pulls, which condenses duplicate entries:

Your signal up to the modem is very good and signal-related events seem to have stopped with the service call.

KipK...as a matter of order, these service events happened after the service call. I reached out to tech support by way of chat and they kept telling me I had to contact the home network support group. So I thought I would check the blogs. The service tech did say that if I am still having issues then it is related to the "junction point" serving my house and others. He said that the conduit supporting the cabling really needs to be cleaned. It was keeping him from replacing cables and connectors on some parts of the assembly.  As for today, I have had 2 or 3 connection drops. I have also seen in other cox areas outside of Arizona that there may be issues related to the cox issued netgear gateway. Any truth to that?  thanks
