I have called multiple time to ony be told my modem is working fine. The past two weeks on Monday my internet stops working. Have to reboot to get it to come back, Tech yesterday said my modem was missing a .cfg file that specifies the rate I should be configured for (is this true?). Why I asked, they didnt know, but assured me it was fixed, 24 hours on the button the errors above were reported again. This had been going on for 8 weeks now.
I have searched web for this fault and find many posts on it, but not actual resoltiuon. Also, midnight last night the modem reported T3 fault. When I told the COMCAST help they immediately went to "it is your cable modem" which is BS. When asked what a T3 fault was she couldn't tell me. I was a COMCST business account holder for 12 years with no issues, switched to residenntial adn nothing but headaches. Field tech coming out tomorrow.
No splitters in my line from the COMCAST distro box in my front yard to my modem.
Forgot to add...when the DS light is blinking my DL speeds are good, 600M service and I am testing in the high 400s, low 500s.
It seems to me Netgear designed the modem to alert you to issues by blinking the DS light.
Tech came out yesterday, first question was "Is your internet out" to which I replied no and he acted as though he was going to leave. I then said I did not call saying my internet was out and went on to explain to him the errors I was receiving. The next 30 minutes consisted of him telling me my modem was bad with no evidence to back up his claim. I have seen this same approach mentioned in our threads I have reviewed here. Being an IT person myself and 30 years in SATCOM, I am use to "blame the distant end" approach to troubleshooting.
Based on everything I could find these errors are associated with noise, either generated by bad connectors, beds, bad cable, etc, none of which I have. It is a direct shot from the cable amp on the street to my cable modem with only the filter (fitering what????) he installed last week when he was at my house. Distance is about 150'. I told him the power coming into my modem seemed high at +10. As I said, I am a SATCOM and I engineer MF-TDMA networks and one thing I know if there is too much power it overdrives the receiver front end and makes recovery of the symbols impossible. Not saying this was the issue, but it was a suspect given my experience.
Without further converation he pulls out a 6db attenuator and puts it on the line at the amp at the street. Power levels are around +3 to +4 range now. 24 hours and so far no errors.
One thing I do notice is T3 timeout message once a day, but from what I read this is normal.
