Hello, Hoping someone can help with figuring out what is happening. My internet drops randomly throughout the day and it is affecting my work now since I get disconnected during conference calls. This problem started out of nowhere about 2 weeks ago after having good connection for about 5 years. I originally had an ASUS RT-N56U and a surfboard SB6141 modem. First I bought a new modem ASUS RT-AC86U and was still experiencing the same problems. I checked the logs on my modem and this is what I saw Downstream Bonding Channel Value Channel ID 13 9 10 11 12 14 15 16 Frequency 855000000 Hz 831000000 Hz 837000000 Hz 843000000 Hz 849000000 Hz 861000000 Hz 867000000 Hz 873000000 Hz Signal to Noise Ratio 35 dB 35 dB 35 dB 35 dB 35 dB 36 dB 36 dB 35 dB Downstream Modulation QAM256 QAM256 QAM256 QAM256 QAM256 QAM256 QAM256 QAM256 Power Level 14 dBmV 14 dBmV 14 dBmV 14 dBmV 14 dBmV 14 dBmV 14 dBmV 14 dBmV Upstream Bonding Channel Value Channel ID 2 4 3 1 Frequency 265000000 Hz 363000000 Hz 299000000 Hz 169000000 Hz Ranging Service ID 50 50 50 50 Symbol Rate 5.120 Msym/sec 5.120 Msym/sec 5.120 Msym/sec 5.120 Msym/sec Power Level 33 dBmV 34 dBmV 35 dBmV 33 dBmV Upstream Modulation [3] 16QAM [3] 64QAM [3] 16QAM [3] 64QAM [3] 16QAM [3] 64QAM [3] 16QAM [3] 64QAM Ranging Status Success Success Success Success Signal Status (Codewords) Bonding Channel Value Channel ID 13 9 10 11 12 14 15 16 Total Unerrored Codewords 449544024 448938218 448954040 449791500 448965130 449834997 449829298 449833280 Total Correctable Codewords 105024 58970 55167 120439 53987 116707 110578 114717 Total Uncorrectable Codewords 498561 268617 256128 631561 242378 574123 573583 586602 ul 22 2020 20:05:29 6-Notice I401.0 TLV-11 - unrecognized OID;CM-MAC= Jul 22 2020 20:05:29 5-Warning Z00.0 MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM-MAC= Jan 01 1970 00:05:10 5-Warning D04.1 ToD request sent - No Response received;CM-MAC= Jan 01 1970 00:05:03 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC= Jan 01 1970 00:00:18 6-Notice N/A Cable Modem Reboot due to T4 timeout ;CM-MAC= Jul 22 2020 20:00:00 3-Critical R04.0 Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC= Jul 22 2020 19:58:26 5-Warning T202.0 Lost MDD Timeout;CM-MAC= Jul 22 2020 19:58:01 3-Critical T05.0 SYNC Timing Synchronization failure - Loss of Sync;CM-MAC= Jul 22 2020 19:56:41 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC= Jul 22 2020 19:56:32 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC= Jul 22 2020 19:56:13 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC= Jul 22 2020 19:56:12 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC= Jul 22 2020 19:54:40 6-Notice I401.0 TLV-11 - unrecognized OID;CM-MAC= Jul 22 2020 19:54:40 5-Warning Z00.0 MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM-MAC= Jan 01 1970 00:00:18 6-Notice N/A Cable Modem Reboot due to T4 timeout ;CM-MAC= Jul 22 2020 19:53:50 3-Critical R04.0 Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC= Jul 22 2020 19:52:02 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC= Jul 22 2020 19:52:02 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC= Jul 22 2020 19:51:50 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC= Jul 22 2020 19:51:47 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC= After researching a bit it seemed like my power levels were off (high downstream?). I talked to tech support on chat and told them about my disconnects and my power levels and all they said was signal was fine and power levels are within spec and that I needed a new modem...…. I asked to have a tech come to my house and check my lines and had one scheduled. So then the tech came out and I told him about the power levels and initial response was "that sounds like ingress". I was hopeful that he could fix the problem. After checking the lines he says signals were all good outside the house and said I needed a new modem..... So I ended up buying a new modem NETGEAR CM1100 and had it activated 7/24/20 around 3:50pm. The next day I start getting disconnects again checked logs and see below 2020-07-25, 17:19:43 Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC= 2020-07-25, 17:19:31 Critical (3) SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;CM-MAC= 2020-07-25, 17:19:30 Warning (5) MDD message timeout;CM-MAC= 2020-07-25, 17:19:29 Critical (3) SYNC Timing Synchronization failure - Loss of Sync;CM-MAC= 2020-07-25, 17:19:29 Critical (3) SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;CM-MAC= 2020-07-25, 17:19:20 Critical (3) SYNC Timing Synchronization failure - Failed to receive MAC SYNC frame within time-out period;CM-MAC= 2020-07-25, 17:18:57 Warning (5) Dynamic Range Window violation 2020-07-25, 17:18:57 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC= 2020-07-25, 17:18:57 Warning (5) Dynamic Range Window violation 2020-07-25, 17:18:57 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC= 2020-07-25, 17:18:48 Notice (6) DS profile assignment change.

@NYin AZ Are you also having this issue with hardwired connections? Jonathan J Cox Moderator

After many unsuccessful attempts of getting the same

I am now starting to get the same issue, off and on all day, after 1 1/2 yrs. I'm thinking this is Cox's service. I am absolutely upset about this. I've restarted this modem 4 times over the weekend 2.5 hz is acting up and 5 is not picking up fast enough This is getting crazy.

I have the same issue. I even upgraded to gigablast and still the speed reads 222 or around there. This is insane, we can't even watch a movie without it buffering. Cox as even came out and checked it several times and changed wires outside. Why should I have to pay for gigablast ? I should be paying for the up to 300 speed. Who do I complain too? The people on the help line do not know what the heck they are doing.

Internet keeps disconnecting randomly all day

Hello,

Hoping someone can help with figuring out what is happening. My internet drops randomly throughout the day and it is affecting my work now since I get disconnected during conference calls. This problem started out of nowhere about 2 weeks ago after having good connection for about 5 years. I originally had an ASUS RT-N56U and a surfboard SB6141 modem. First I bought a new modem ASUS RT-AC86U and was still experiencing the same problems. I checked the logs on my modem and this is what I saw

After researching a bit it seemed like my power levels were off (high downstream?). I talked to tech support on chat and told them about my disconnects and my power levels and all they said was signal was fine and power levels are within spec and that I needed a new modem...…. I asked to have a tech come to my house and check my lines and had one scheduled. So then the tech came out and I told him about the power levels and initial response was "that sounds like ingress". I was hopeful that he could fix the problem. After checking the lines he says signals were all good outside the house and said I needed a new modem.....

So I ended up buying a new modem NETGEAR CM1100 and had it activated 7/24/20 around 3:50pm. The next day I start getting disconnects again checked logs and see below

Can anyone help me figure out if it really is again my equipment or is it something with cox? Had a couple disconnects while typing this out. Sorry for the long post.

Thank you

  I am now starting to get the same issue, off and on all day, after 1 1/2 yrs. I'm thinking this is Cox's service. I am absolutely upset about this. I've restarted this modem 4 times over the weekend 2.5 hz is acting up and 5 is not picking up fast enough This is getting crazy.

    Are you also having this issue with hardwired connections?

I have the same issue. I even upgraded to gigablast and still the speed reads 222 or around there. This is insane, we can't even watch a movie without it buffering. Cox as even came out and checked it several times and changed wires outside. Why should I have to pay for gigablast ? I should be paying for the up to 300 speed. Who do I complain too? The people on the help line do not know what the heck they are doing.

Welcome to Cox premium internet, my friends. This has been going on for years, I'm on my 3rd modem now, just renting from Cox because I know what they're going to say next: Replace your modem. Again. Thank God for Verizon 4g service on my tablet, no more dropped conference calls just when I'm about to present. Who knew my wireless cell service would one day be much more reliable than my home internet.

I have the same problem in AZ. Internet working intermittent every day, it started Monday 7/27/2020. The good thing is that we have a verizon hotspot and it saved the day (week), since my wife is working from home and kids are in remote learning.

    85032 has been intermittently dropping since the 21st of July and now the last three days in August. Speeds have slowed to a crawl. With school starting on Wednesday, this is unacceptable. I have Cox Panoramic WiFi with a rented modem/router combo. This is a Cox problem as it affecting everyone in Phoenix and the surrounding cities.
