Re: Cable modem randomly rebooting & poor connection
Hello I'm still having issues with my connection, whilst it has improved my hub still keeps disconnecting / reconnecting at random times causing me to be booted from various applications (also using my connection for work). This happens both in modem and router mode so it isnt related to my equipment. Whenever the hub loses connection it shows: SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing (hub then flashes white LED Heres my reent logs: Time Priority Description 05-12-2023 02:40:12 warning DBC-REQ Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.1; 05-12-2023 02:40:12 notice US profile assignment change.

Over the past month or so I keep having connection issues, my Superhub was recently changed from a Superhub 2 (almost flawless) to a Superhub 5. Since this was changed my router also now reboots randomly which is annoying as it constantly keeps disconnecting me. Could someone take a look at my levels / connection to see what the issue is being caused by, apparently there was an SNR fault which was resolved however I'm still having issues. 3.0 Downstream channels Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID 1 330000000 7.5 42 QAM 256 25 2 178000000 8.4 43 QAM 256 6 3 186000000 8.4 42 QAM 256 7 4 194000000 8.5 42 QAM 256 8 5 202000000 8.4 42 QAM 256 9 6 210000000 8.7 42 QAM 256 10 7 218000000 8.5 42 QAM 256 11 8 226000000 8.4 42 QAM 256 12 9 234000000 8.4 42 QAM 256 13 10 242000000 8.2 42 QAM 256 14 11 250000000 8 42 QAM 256 15 12 258000000 7.8 42 QAM 256 16 13 266000000 7.8 42 QAM 256 17 14 274000000 7.7 42 QAM 256 18 15 282000000 7.5 42 QAM 256 19 16 290000000 7.5 42 QAM 256 20 17 298000000 7.6 42 QAM 256 21 18 306000000 7.7 42 QAM 256 22 19 314000000 7.6 42 QAM 256 23 20 322000000 7.5 42 QAM 256 24 21 338000000 7.6 41 QAM 256 26 22 346000000 7.4 42 QAM 256 27 23 354000000 7 42 QAM 256 28 24 362000000 7.1 42 QAM 256 29 25 370000000 7.3 42 QAM 256 30 26 378000000 7.2 42 QAM 256 31 27 386000000 7.1 42 QAM 256 32 28 394000000 7.1 42 QAM 256 33 29 402000000 7.2 42 QAM 256 34 30 410000000 6.8 42 QAM 256 35 31 418000000 6.4 42 QAM 256 36 3.0 Downstream channels Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1 Locked 42 2 0 2 Locked 43 0 0 3 Locked 42 0 0 4 Locked 42 0 0 5 Locked 42 0 0 6 Locked 42 0 0 7 Locked 42 0 0 8 Locked 42 0 0 9 Locked 42 0 0 10 Locked 42 0 0 11 Locked 42 0 0 12 Locked 42 0 0 13 Locked 42 0 0 14 Locked 42 0 0 15 Locked 42 0 0 16 Locked 42 1 0 17 Locked 42 0 0 18 Locked 42 0 0 19 Locked 42 0 0 20 Locked 42 0 0 21 Locked 41 1 0 22 Locked 42 1 0 23 Locked 42 1 0 24 Locked 42 1 0 25 Locked 42 3 0 26 Locked 42 3 0 27 Locked 42 3 0 28 Locked 42 4 0 29 Locked 42 1 0 30 Locked 42 6 0 31 Locked 42 5 0 3.1 Downstream channels Channel Channel Width (MHz) FFT Type Number of Active Subcarriers Modulation (Active Profile) First Active Subcarrier (Hz) 159 92 4K 1800 QAM 4096 1128 3.1 Downstream channels Channel ID Locked Status RxMER Data (dB) PLC Power (dBmV) Corrected errors (Active Profile) Uncorrectable errors (Active Profile) 159 Locked 44 8.0 453025 0 3.0 Upstream channels Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID 0 49600000 45.3 5120 QAM 64 9 1 43100000 44.8 5120 QAM 64 10 2 36600000 44.3 5120 QAM 64 11 3 30100000 44 5120 QAM 64 12 4 23600000 43.8 5120 QAM 64 13 3.0 Upstream channels Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts 0 ATDMA 0 0 0 0 1 ATDMA 0 0 0 0 2 ATDMA 0 0 0 0 3 ATDMA 0 0 4 0 4 ATDMA 0 0 0 0 3.1 Upstream channels Channel Channel Width (MHz) Power (dBmV) FFT Type Modulation 14 10 39.5 2K QAM 256 3.1 Upstream channels Channel Channel Type Number of Active Subcarriers First Active Subcarrier (Hz) T3 Timeouts T4 Timeouts 14 OFDMA 200 74000000 0 0 16-11-2023 02:08:02 warning DBC-REQ Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.1; 16-11-2023 02:08:02 notice US profile assignment change.
