Is Cox having bandwidth issues ?
For the last couple of months I have been experiencing my NetGear CG300D getting bumped off weekdays during peak usage times (i.e. 11:30a - 12:30p, and around 4:30p - 7p). Although during the early morning, mid-afternoon , and late evening hours there are no problems. On the last Labor Day the connection was going down about every 15-30 minutes. Today is July 5th, the connection is again going down every 15 - 30 minutes on both yesterday July 4th and today. The only way I've found to re-establish a connection is to reboot the gateway. Cox representatives say that they haven't heard of the problem. Doing a quick Google search shows many people complaining about this issue. i know this forum is very limited in its scope of reaching people, but Are there any subscribers in the Omaha area experiencing this problem ? Which quadrant of the city are you located in Northeast, Southeast, Northwest, Southwest, Bellevue, La Vista, Papillion ? I have included a portion of the error log on my NetGear gateway (XX:XX:XXX:XX:XX:XX is my MAC addr) Fri Jul 05 14:12:01 2013 Notice (6) TLV-11 - unrecognized OID;CM-MAC=XX:XX:XXX:XX:XX:XX;CMTS-MAC=50:57:a8:88:f9:88;CM-QOS=1.1;CM-VER=3.0; Fri Jul 05 13:53:29 2013 Critical (3) Unicast Ranging Received Abort Response - Re-initializing MAC;CM-MAC=XX:XX:XXX:XX:XX:XX;CMTS-MAC=50:57:a8:88:f9:88;CM-QOS=1.1;CM-VER=3.0; Thu Jul 04 14:32:46 2013 Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=XX:XX:XXX:XX:XX:XX;CMTS-MAC=50:57:a8:88:f9:88;CM-QOS=1.1;CM-VER=3.0; Thu Jul 04 14:32:34 2013 Critical (3) Unicast Ranging Received Abort Response - Re-initializing MAC;CM-MAC=XX:XX:XXX:XX:XX:XX;CMTS-MAC=50:57:a8:88:f9:88;CM-QOS=1.1;CM-VER=3.0; Thu Jul 04 13:15:30 2013 Critical (3) Unicast Ranging Received Abort Response - Re-initializing MAC;CM-MAC=XX:XX:XXX:XX:XX:XX;CMTS-MAC=50:57:a8:88:f9:88;CM-QOS=1.1;CM-VER=3.0; Thu Jul 04 13:10:46 2013 Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=XX:XX:XXX:XX:XX:XX;CMTS-MAC=50:57:a8:88:f9:88;CM-QOS=1.1;CM-VER=3.0;3.9KViews0likes4CommentsConstant T3 time-outs & connection drops even after replaced gateway 3x
I am having constant connection drops, over the last several weeks, withconstantT3 time-out errors in the gateway logs. I have replaced the modem/router twice (once with an older one that I still had on hand, and then with a brand new gateway SurfboardSBG6782-AC) for a total of 3 different gateways. The IPs have been reset multiple times, after disconnecting the gateway overnight, and after the equipment changes. I have also had the signal reset 4 or 5 times. The connection drops for anywhere from a few seconds, to 10 minutes or so at a time. Usually, it returns on its own, but sometimes, I have to restart the gateway to get it back. It is extremely disruptive to my productivity. When the connection is stable, I have excellent speed according to speedtesting (50+mps) but I do not feel the benefits of this because of the constant timing out. I am seeing the connection drop every few minutes, making it impossible to do anything online. I have connected the gateway to a cable outlet in a different room, to make sure that the problem was not with the individual connector. The problem actually seemed worse in the other room. I have no TVs connected to any cable outlets at all, as I am not paying for TV service. I still got constantT3 time-out errors in the gateway logs. I have a desktop connected to the gateway by ethernet, a laptop and ipad connected by wifi. I have tested disconnecting each of these devices and using one at a time, to see if I can isolate the problem to a particular device, but there is no change. The connection still drops constantly. Here is a a screenshot of my gateway connection results http://screencast.com/t/QjFjT2AMMkq Here is a screenshot with a sample of my most recent event log.http://screencast.com/t/xcGJah8Z2lk6 Any idea what could be going on here? I have googled this problem until my eyes bleed, but I can't find a solution. Do I need to have a technician out?1.4KViews0likes1Comment
Intermittent Disconnects
I've had my Cox internet for about 5 months now, and only in the last month has this issue appeared. Multiple times a day my internet connection will briefly drop out before reconnecting within about a minute. In between these disconnections I have no issues at all, but they've been happening in the 10s of times per day lately. I tried resetting my router and modem, neither of which had any effect on how often I disconnect. I did ping testing on my router and had sub millisecond responses when I lose my connection, so my router isn't the issue. When I looked on the longs for my modem I noticed that there have been multiple errors that frequently repeat themselves: MDD message timeout; SYNC Timing Synchronization failure - Failed to acquire FEC framing; Started Unicast Maintenance Ranging - No Response received - T3 time-out; The MDD and SYNC messages always happen at the same time, but don't seem to be tied to the T3 time-outs. Both of these two sets of messages coincide with my disconnects. From what searching I've done, T3 timeouts seems to indicate that there's an upstream issue so here's my information on that. Modem: Motorola SB6183 Upstream Bonded Channels Channel | Lock Status | US Channel Type | Channel ID | Symbol Rate | Frequency | Power 1 Locked ATDMA 3 5120 Ksym/sec 28414000 Hz 43.7 dBmV 2 Locked ATDMA 1 2560 Ksym/sec 17154000 Hz 42.3 dBmV 3 Locked ATDMA 2 5120 Ksym/sec 21984000 Hz 42.3 dBmV 4 Locked ATDMA 4 5120 Ksym/sec 34844000 Hz 43.8 dBmV As for cable splits - I have no idea, I live in a multi-unit apartment building. Any advice or help is appreciated, thanks for your time.1.4KViews0likes1Comment
