Message: [QUOTE="Guest2, post: 165715, member: 21318"]This question is about "Sudden slowdown in internet speed to average of 0.9 mbps", with Time Warner Cable internet and apps.  For the past several days, my internet has gotten unbearably slow, and resetting my modem hasn't done anything to help. I see that there have been some errors logged by my modem and am hoping that someone can point me in the right direction as to how to get this resolved. Here are the errors:[TABLE]<tr><td >Oct 25 2016 01:40:28</td><td >3-Critical</td><td >R02.0</td><td >No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 25 2016 01:40:28</td><td >6-Notice</td><td >I401.0</td><td >TLV-11 - unrecognized OID;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 25 2016 01:40:28</td><td >5-Warning</td><td >Z00.0</td><td >MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Jan 01 1970 00:13:03</td><td >3-Critical</td><td >R02.0</td><td >No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Jan 01 1970 00:12:21</td><td >5-Warning</td><td >R09.0</td><td >B-INIT-RNG Failure - Retries exceeded;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Jan 01 1970 00:12:21</td><td >3-Critical</td><td >R02.0</td><td >No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Jan 01 1970 00:00:15</td><td >6-Notice</td><td >N/A</td><td >Cable Modem Reboot due to T4 timeout ;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:00:00:00:00:00;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 25 2016 01:26:27</td><td >3-Critical</td><td >R04.0</td><td >Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 25 2016 01:26:24</td><td >5-Warning</td><td >T202.0</td><td >Lost MDD Timeout;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 25 2016 01:26:21</td><td >3-Critical</td><td >R04.0</td><td >Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 25 2016 01:26:01</td><td >3-Critical</td><td >T05.0</td><td >SYNC Timing Synchronization failure - Loss of Sync;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 21 2016 07:16:48</td><td >3-Critical</td><td >R02.0</td><td >No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 21 2016 00:06:19</td><td >3-Critical</td><td >R06.0</td><td >Unicast Maintenance Ranging attempted - No response - Retries exhausted;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 21 2016 00:06:19</td><td >3-Critical</td><td >R03.0</td><td >Ranging Request Retries exhausted;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 21 2016 00:06:18</td><td >3-Critical</td><td >R02.0</td><td >No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 10 2016 04:28:06</td><td >6-Notice</td><td >I401.0</td><td >TLV-11 - unrecognized OID;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 10 2016 04:28:05</td><td >5-Warning</td><td >Z00.0</td><td >MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 10 2016 04:27:51</td><td >3-Critical</td><td >R02.0</td><td >No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 10 2016 04:27:31</td><td >6-Notice</td><td >I401.0</td><td >TLV-11 - unrecognized OID;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr><tr><td >Oct 10 2016 04:27:31</td><td >5-Warning</td><td >Z00.0</td><td >MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM-MAC=20:3d:66:04:e2:94;CMTS-MAC=00:01:5c:7a:e8:4a;CM-QOS=1.1;CM-VER=3.0;</td></tr>[/TABLE]This topic covered Sudden slowdown in internet speed to average of 0.9 mbps, and TWC cable internet service.[/QUOTE]
