Internet keeps dropping
My main issue is that the internet will drop for a second to a minute and then reconnect, this happens over and over almost every day. I have replaced my modem, cables both coaxial and CAT. I have disconnected all devices in my home other than the computer plugged directly to the modem. There is no splitter attached to the line. Attached is a screenshot of my modem status showing major problems with uncorrectables and power. The original technician who installed the Cox internet at our home commented how the signal was not very good but at the time it was within limits if he plugged in a power booster. Every time I call COX support they say everything looks fine and they can't do anything. Does anyone have any suggestions? Thanks for your time.https://ibb.co/7GgqyXw1.5KViews0likes0CommentsHigh Uncorrectable Errors
Hi All, Ive been having really crappy internet for the last few weeks and a check of my modem status page shows the following uncorrectable errors on channels 13, 14 and 15. Cox say they dont see these on their side. Please bear in mind this is in two hours of usage from a reboot. Any recommendations?

What could be the problem?
I live in Springfield, VA. I have a Netgear CM600 modem and have been receiving uncorrectables of hundreds of thousands and millions in a very limited uptime (< 24 hours). I am having this problem on every channel operating between 649-813MHz. The amount of uncorrectables varies, but is still very high for all of them. Alongside this problem, I have been experiencing network instability and modem crashing about every hour or so. Side note: I have tested a different modem (Arris SB6190) and have gotten the same, if not worse, results. The event log for each modem has showed me a different combination of errors like: -RCS Partial Service -SYNC Configuration Time out -Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out -No Ranging Response received - T3 time-out Cox Technical Support, including the technician who came into my house, said that everything on their side looked good (GREEN). This problem arose after changing my Motorola SURFboard modem to something from this decade (ie. SB6190 and CM600) due to a small UPLOAD SIDE packet loss issue (1-3%) I was having while gaming online. Never any crashing until now. Between the times when these errors occur in the event log, my internet is lightning fast (besides the upload packet loss issue still being present). >These are the values forDOWNSTREAMwith the Netgear CM600 at an uptime of around 90 minutes. <tabindex=-1>Downstream Bonded Channels Channel Lock Status Modulation Channel ID Frequency Power SNR Correctables Uncorrectables 1 Locked QAM256 3 687000000 Hz 9.1 dBmV 39.2 dB 214828 132675 2 Locked QAM256 1 675000000 Hz 9.3 dBmV 38.5 dB 65347 12412 3 Locked QAM256 2 681000000 Hz 9.6 dBmV 39.3 dB 92489 14832 4 Locked QAM256 4 693000000 Hz 9.3 dBmV 39.3 dB 219991 161237 5 Locked QAM256 5 699000000 Hz 8.8 dBmV 39.1 dB 232634 167674 6 Locked QAM256 6 705000000 Hz 8.5 dBmV 38.9 dB 231551 125552 7 Locked QAM256 7 711000000 Hz 8.4 dBmV 38.8 dB 206782 73208 8 Locked QAM256 8 717000000 Hz 8.1 dBmV 38.6 dB 159890 36191 9 Locked QAM256 17 771000000 Hz 8.7 dBmV 39.1 dB 37129 42243 10 Locked QAM256 18 777000000 Hz 8.8 dBmV 39.1 dB 30994 4741 11 Locked QAM256 19 783000000 Hz 8.9 dBmV 39.2 dB 24894 2178 12 Locked QAM256 20 789000000 Hz 8.4 dBmV 38.9 dB 22073 3062 13 Locked QAM256 21 795000000 Hz 7.9 dBmV 38.7 dB 15069 2258 14 Locked QAM256 22 801000000 Hz 7.5 dBmV 38.4 dB 12652 1561 15 Locked QAM256 23 807000000 Hz 7.2 dBmV 38.3 dB 20874 5991 16 Locked QAM256 24 813000000 Hz 7.8 dBmV 38.6 dB 58248 76267 UPSTREAM: <tabindex=-1>Upstream Bonded Channels Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power 1 Locked ATDMA 1 2560 Ksym/sec 17154000 Hz 44.5 dBmV 2 Locked ATDMA 2 5120 Ksym/sec 21984000 Hz 46.0 dBmV 3 Locked ATDMA 3 5120 Ksym/sec 28414000 Hz 47.0 dBmV 4 Locked ATDMA 4 5120 Ksym/sec 34844000 Hz 47.5 dBmV 5 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 6 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 7 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 8 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV (I assume that I do not have the option for 8 Upstream channels because the Arris SB6190 did not even list the last 4 channels) Could this problem possibly be inside my home? The technician took out a splitter from my setup and placed my internet cable on a splitter with an amplifier. The problem does not seem to have changed though. I have another, higher-level, technician coming in 2 days. Is there anything that I can show them to help pinpoint the problem?Solved16KViews1like18Comments
