Are you able to see the return path and downstream frequencies? Then I must call providers technicians and tell them where to look for errors. Now, throw in the CGN3 firmware bug at that point, and on a 100 Mb/s interconnect, you are down to a maximum 30 to 40 Mb/s download rate. The process repeats until the modem and the CMTS establish communication at an acceptable level. Looking at the tables a couple of things are evident. you miss some Non critical field in dhcp response. 22-02-2020 22:56 - edited ‎22-02-2020 22:57. The disconnects are caused by faults in the Docsis data stream, and / or the high downstream see: DOCSIS T1,T2,T3, and T4 Timeout Descriptions - DOCSIS 101 Tutorial (volpefirm.com) If you buy your own router and put the http://www.lowes.ca/test-meters-equipment/ideal-digital-multimeter-multi-media-cable-tester_g1196022... Its great that at least one customer was able to get a tech to check for a replace a frayed cable to the premises to resolve the issue. will be: 406Mhz (or something like that), and different US channel). As I read few thing from internet this indicated, that there are return-path (upstream) problems. Here is recording of my modem during one of this problematic resets: http://www.youtube.com/watch?v=0fUZoHbnHd4, 10/23/2008 21.57 68000300 03 DHCP WARNING - Non-critical field invalid in response. Just ask! Perhaps there is intermittent noise ingress into the line (s) somewhere. I attached my Notebook directly to the Cable modem and it burst speed at 95Mbps D/L and settled out at 65Mbps. If you have any doubts on the house Ethernet…..read on. ‎07-18-2014 I have been monitoring the speed as advertised and using the Rogers speed check at speedcheck.rogers.com/en.html and have only gotten as high as 33.97 down and 5.38 up. Error priority: critical. go to the connection tab and double check your power levels. Reading through you post again, I had a few thoughts on the speed issue. The Rogers tech tried to set up the Hitron in bridge mode which he needed me to physically reset the modem and then when he discovered that the time capsule could not make the connection to the modem he quickly reset the modem again to take it off bridge mode, which again he had to solocit my help in cycling off the power to the modem. 29.05.2019 09:39:30 No Ranging Response received - T3 time-out;CM-MAC=xxx;CM-QOS=1.1;CM-VER=3.1; 29.05.2019 09:39:31 CM-STATUS message sent. I also connected modem to car battery to exclude power supply problem. It could prevent it from fully registering, but not flap. Da ich öfters mit Looking at your speed issue I would say that the slow upload could be attributed to the single upstream channel, if that is the only channel up. ‎07-18-2014 If you can, at this point, check the device to device data rate to see what it indicates, that will tell you what you should expect on a speedtest. The connection problem has virtually went away, I had another critiacl error show up again this morning. ‎07-18-2014 Thanks so much for your help, I was able to identify I do have a problem with my internal wiring as it realtes to the speed issue. 2015/6/2
14:30:55 Notice. So there must be problem at providers side. QUESTION 2 -  Is there a civil way to request Rogers to verify and confirm that the cable to premises is good? DOCSIS timeout descriptions or errors and what they mean. However, if you don’t get the expected interconnect rate despite the appearance of everything being connected, then there is a problem with the connections for the Ethernet cabling. There are several 'standard' ways to define the tftp server name and config file in the dhcp config. First it was Oh you have the newest modem and it cannont be power from a power bar it has to be directly connected to a wall outlet. But I'm happy for now, that is working. Some cable modem models/brands may have cleaner upstream signal reducing the number of T3 timeouts (reportedly Zoom 5341-00-00J, for example) T4 Timeout - Received Response to Broadcast Maintenance Request, But no "Explanation: The cable modem has sent 16 Ranging Request (RNG-REQ) messages without receiving a Ranging Response (RNG-RSP) message in reply from the CMTS. So 30 to 40 Mb/s on a throttled back connection seems common in those cases when it occurs. [Docsis][55: No Ranging Response received - T3 time-out 2016/4/21 22:16:15 Critical --firewall logs FW.IPv6 INPUT drop, 431 Attempts. to get more current information in the cable modem . Can you tell if the modem is frequency hopping? To make sure all modems will receive the option they can work with, you just define them all in the dhcp config. I can't think of any reason why a bad DHCP server would make a modem do that. So when your modem receives the extra options (telling it the same info it already knows), it doesn't know how to read them and pops that warning. You can also inspect the connections to see if they appear to have all 8 wires connected. No Ranging Response received - T3 time-out;CM-MAC=b8:16:19:f7:e2:b5;CMTS-MAC=60:73:5c:72:9b:79;CM-QOS=1.1;CM-VER=3.0; first one didn't show up until a worker came out and worked on it but i think it's the main line that connects at the pole keeping a eye on you guy's smooth talk him saying it should always look like that yea no neighbor has cox cable and … Atttempting continuous pings from that location to the home system shows packet loss at varying rates. Power -5 dBmV The log showed not receiving data telling to the modem to adjust it's power level. Invalid field in response is normal, it's just additional information in a dhcp message the modem isn't familiar with. Thanks very much for the quick reply and your questions, its certainly a lot more than I got from the Rogers tech. 10/23/2008 21.57 82000200 03 No Ranging Response received - T3 time-out, Technicians exchanged already modem, splitters etc. 03:08 PM No Ranging Response received - T3 time-out: These are actually fairly common. De connect box is bedraad aangesloten op een 'extra wifi punt ziggo'. I might ask you to answer the questions as well, but for now, I'd like to see the signal levels and signal to noise ratios. T3 and T4 timeouts are described in much more detail I'll keep my fingers crossed. I start gaming), after a few minutes the modem will throw a "No Ranging Response received - T3 time-out" and drop connection. De netwerkhistorie laat zien: No Ranging Response received - T3 time-out.
