Please Help Arris SBG 7400AC2 Can someone please help i get hit wit the RCS Partial Service and then the Sync Timing failure once or twice a miniute. Its making my Internet really intermittent. I have a Arris SBG7400AC2 I have 24 Downstream Channels but it looks like its only using 16. Should I be worried? Is it a Modem problem, or something on the ISP end? 5/15/2019 10:20 84000700 5 RCS Partial Service;CM- 5/15/2019 10:21 84000500 3 SYNC Timing Synchronization failure - Loss of Sync;CM 5/15/2019 10:22 84000700 5 RCS Partial Service;CM- 5/15/2019 10:22 84000500 3 SYNC Timing Synchronization failure - Loss of Sync;CM 5/15/2019 10:22 84000700 5 RCS Partial Service;CM- 5/15/2019 10:23 84000500 3 SYNC Timing Synchronization failure - Loss of Sync;CM DCID Freq Power SNR Modulation octets Correcteds Uncorrectables Downstream 1 22 909mhz 0.40 dbmv 37.36 db 256qam 12184258 14113 121820 Downstream 2 1 783 2.90 40.37 256 10039275 15 0 Downstream 3 789 2.70 38.61 256 9563906 12 0 Downstream 4 795 3.00 38.98 256 9933287 0 0 Downstream 5 801 3.30 38.98 256 10009372 5 0 Downstream 6 807 3.60 39.98 256 10388972 7 0 Downstream 7 813 3.80 38.61 256 10403044 33 0 Downstream 8 819 3.20 38.61 256 10409461 26 0 Downstream 9 825 1.00 37.36 256 10338283 9 0 Downstream 10 879 .80 37.64 256 10678497 0 0 Downstream 11 885 .40 37.64 256 10492792 9 0 Downstream 12 891 .60 37.64 256 10343465 14 0 Downstream 13 897 .60 37.64 256 10606016 17 0 Downstream 14 903 .70 37.64 256 10304383 5886 71627 Downstream 15 915 .30 37.64 256 10425493 14604 194266 Downstream 16 921 -.40 37.64 256 10545731 13359 214549 Downstream 17 357 Downstream 18 363 Downstream 19 369 Downstream 20 375 Downstream 21 381 Downstream 22 387 Downstream 23 393 Downstream 24 399
