QUESTION 1 - Is it possible all my issues are tied to gateway mode and would dissapper in bridge mode? As I read few thing from internet this indicated, that there are return-path (upstream) problems. Don't worry about the occasional one. [Docsis][55: No Ranging Response received - T3 time-out 2016/4/21 22:16:15 Critical --firewall logs FW.IPv6 INPUT drop, 431 Attempts. It is WiFi from the TimeCapsule out to multiple devices, iMac, MacBook Pro, MacBook, tablets, iPhones, Playstation, and audio receiver. The cable modem is certified to work on any Euro-DOCSIS based HFC cable system and is certified Euro-DOCSIS 2.0 by Excentis"). With help of my recording of modem during reset, they figured out, that modem looses sync with CMTS (first light that goes off when reset happens is: Cable link). Event Type Code: 24 8: 2020-12-11 03:32:24 82000400 critical Received Response to Broadcast Maintenance Request, But no Unicast Any snow or audio distortion especially on the low channels? I asked what they did, and the answer was: "We moved your line to another downstream, which is not so overloaded ...". I checked the dowstream/upstream summaries and they look normal. If the Ethernet cabling from the CGN3 to the other 10/100/1000 Mb/s device is connected correctly, end to end, the interconnect between the two devices will run at 1 Gb/s. Looking at the tables a couple of things are evident. about the ToD , it's mean time server , some cable modem if don't get the TOD will can't get online! DHCP WARNING - Non-critical field invalid in response. Check as well the WAN uptime and see if it has reset to 0 when this drop occurs. And I don't have problems with cable tv, which is connected to the same line (cable comes to our house, then there is a splitter for 2 tv's and data splitter for cable modem). The CMTS and modem ping-pong as a way for the CMTS to know the CM is still alive for the CMTS to make adjustments to the CM. [Docsis] [690]: SW upgrade Failed after download - SW File corruption. Explanation: The cable modem did not receive a broadcast maintenance opportunity in which to transmit a Ranging Request (RNG-REQ) within the T2 timeout period (approximately 10 seconds). My download/upload speeds are great. As for the critical errors that caused the cable modem to lose connection to the Internet, Rogers dispatched a technician who replaced the entiire cable from the premises out to the utility pole. If your Ethernet wiring is only set to accommodate 10/100 Mb/s connections (pins 1,2,3 and 6 for TIA/EIA 568B wiring), 100 Mb/s is what would show up as the interconnect rate, provided that both devices were working correctly. Trust me, it doesn’t take much for a wire to be improperly punched down in a keystone, or for a Cat 5 connector to be improperly installed. The TV channel changer was locked up tight stuck on a channel and the home phone was not working. That T-3 timeout is the CM not hearing back from the CMTS when it should. Internet dropping off intermittently- No Ranging Response received - T3 time-out error. If you have any doubts on the house Ethernet…..read on. Event Type Code: 7; Chan ID: 3; DSID: N/A; MAC Addr: N/A; OFDM 2010-01-25 14:32:00 3-Critical R02.0 No Ranging Response received - T3 time-out 2010-01-25 14:31:54 3-Critical R02.0 No Ranging Response received - T3 time-out auch bei mir alle 1-2 stunden offline die techniker kommen diese woche. Just ask! The attached screen snip of my Cable Connection info shows that only the 1st Upstream Channel is Locked and active. Can you tell if the modem is frequency hopping? Error type: 82000200. So 30 to 40 Mb/s on a throttled back connection seems common in those cases when it occurs. If you see multiple T3 timeouts in a single day, it's an indication that a less-than-optimal condition exists. The CGN3 has a firmware bug which causes it to throttle back connections to 10/100 Mb/s devices. but i think it's ok. i think you can try http://homepage.ntlworld.com/robin.d.h.walker/docsdiag/ Usually this ranging interval can be configured on the CMTS; typically this is set to about 10 to 20 seconds. Did the upstream table not paste in entirely? When I lost DOCSIS 3.1, dl speeds decreased 30-40%. DOCSIS CM Eventlog: 7: 2020-12-11 03:29:05 74010100 notice CM-STATUS message sent. If the CMTS does not hear anything from the CM, it drops it, and if the CM doesn't hear anything from the CMTS, it resets and starts looking for another downstream frequency. 10:10 PM. Mijn TV en de appleTV zijn op hun beurt weer bedraad aangesloten op … 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. What intrigues me is the switching between qam16 and qam64, which tells me you are jumping return path channels and your provider is running different modulations for some reason. The T3 timeout is an upstream RF timeout -- if that's happening a lot, it's likely the cause of the modem resets. Looking at the log, these two entries are repeating. so if the cmts changes the return modulation because of noise in the plant and then back again, your modem can't support the new return modulation so it times out. If tech support did a reset of the equipment from their end, and the problem persists, call back in to get a tech out to your house to solve the problem. I have the Hitron CGN3 with Hybrid Fibre 60/10 service. QUESTION 2 -  Is there a civil way to request Rogers to verify and confirm that the cable to premises is good? No. The cable modem is resetting its cable interface and restarting the registration process. Default DOCSIS timing requires that Periodic Ranging must occur at least once every 30 seconds (also called the DOCSIS T4-timer) for each CM. Power -5 dBmV The cable was frayed and had water damage. Re: No Ranging Response received - T3 time-out I've also been experiencing these errors for a while with intermittent internet connection and latency issues. Error Event: No Ranging Response received - T3 time-out;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.0; Error Event: Unicast Ranging Received Abort Response - initializing ;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.0; These occur multiple times and it is always after my Internet connection drops out. I also connected modem to car battery to exclude power supply problem. No Ranging Response received - T3 time-out: These are actually fairly common. 2015/6/2
14:30:55 Notice. Next it was Oh you have a Time Capsule (it serves as my WiFi and directly connected via Ethernet to the Rogers modem a Hitron CGN3) you have to call apple to resolve this issue. 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. "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. I recommend you go and buy a new modem, best buy, office max, etc... Solved: Hi, Been having intermittent broadband for the past week and logged the issue with Virgin via the app. 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 Can't find what you're looking for? Diskutiere No Ranging Response received - T3 time-out im FRITZ!Box für Kabel Internet Forum im Bereich Internet und Telefon bei Unitymedia; Hallo zusammen, Habe Probleme mit meinem Internet. That kinda gets the point accross. Here are the links to the LAN testers: http://www.lowes.ca/test-meters-equipment/ideal-linkmastertrade-tester_g1199379.html. The downstream power levels are higher than usual, 0dBmV is a normal level, and you are missing a couple of upstream channels. At -5 dB it 'should' be fine, but I've seen weirder stuff. Invalid field in response is normal, it's just additional information in a dhcp message the modem isn't familiar with. What do you mean by: " you lost some field in dhcp server"? 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. 2016/4/23 21:58:02 Firewall Blocked First, a little explanation. The CMTS and modem ping-pong as a way for the CMTS to DOCSIS timeout descriptions or errors and what they mean. I don't think the modem you have supports docsis 2.0. docsis 1.1 yes, but 2.0 I'm not sure. Had an engineer come around - 4365811 Time Priority Description 13/08/2020 11:26:33 critical No Ranging The upload remained the same at 5.65Mbps. There are also a lot of errors and critical messages. 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 Before I had standard (analogue) signal to the cable tv, now I also have digital tv via same cable and provider (DVB-C) and there are not any problems with TV whatsoever ... At last my provider after a lot of mails, calls, faxes, etc ... managed to get my line straight. 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. I'm willing to bet it's the tftp options. ‎07-18-2014 Can you log into the CGN3 and copy the downstream and upstream tables as shown in the following thread and post them into this thread. If there is a wire that is not connected correctly or perhaps loose, depending on which one it is, the two devices will auto-negotiate down to some common data rate that they can both agree on. Certainly a lot less than advertised, only 68% of the speed I signed onto. Whenever the line comes under load (E.g. Best regards from Slovenia, and thanks in advance for help! Solved! to get more current information in the cable modem . Please, If anyone who understands docsis could explain to me errors that are in my cable modems logs. De NAS-disk is bedraad aangesloten op de connect box. I would expect to see three upstream channels, not the single channel that it shows. Am I correct? It requires a number of misses before either happens. that way it's new and you don't have to lease it from your provider. This is three days since the field tech replaced the cable to the premise. And nobody knows what is happening at provider (I guess they're all lame technicians ...), Downstream Intermittent connection - DOCSIS Event log display... That's what we're here for! This does not appear to be a router or wifi issue, the router doesn't require a reboot and RSSI values are fine, no configuration changes on that end. by The goal of the Rogers Community is to help you find answers on everything Rogers. Only worry if you start to see a bunch of them. Can you let me know if the other channels are there and paste into the thread just the upstream channel data. So there must be problem at providers side. 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. Do you get cable TV through this connection? In that case the problems are with the modem and RG6 cabling. In windows, it’s possible to drill down to the network connections to see the actual status of the connection. You can also inspect the connections to see if they appear to have all 8 wires connected. Is there problem with DHCP server on my line? please let me know how you make out. I'll attempt to respond to the questions. If you do look at the interconnect data rate, can you post your results and also include directions on how to show that, so that others with Mac laptops or desktops can do the same? De netwerkhistorie laat zien: No Ranging Response received - T3 time-out. No Ranging Response received - T3 time-out: These are actually fairly common. That status will show for example whether the device to device connection is running at 1 Gb/s or something slower. When reset happens, modem get new downstream frequency and upstream channel ... (now is DS freq. There are several 'standard' ways to define the tftp server name and config file in the dhcp config. Those levels look normal. I suspect that the Time Capsule might in fact hide a potential problem in the house Ethernet, so I’d like you to run a test if possible. The tech re-sets both and it has been working somewhat acceptable since. this is mean you lost some field in dhcp server. 22-02-2020 22:56 - edited ‎22-02-2020 22:57. The ends are terminated with the best compression fittings in the industry and brand new. The process repeats until the modem and the CMTS establish communication at an acceptable level. 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 … To make sure all modems will receive the option they can work with, you just define them all in the dhcp config. [Dhcpc] [2491]: erouter0 got new IP X.X.X.X. Provider leases this Thompson modems (and they exchanged me already 3 modems which were all new), and I can't buy any new cable modem here in Slovenia, as far as I know ... And modem is Docsis 2.0 capable (This is from modem's data sheet:"euro-Docsis approved Design. Please help me with THG-540 and my provider, http://homepage.ntlworld.com/robin.d.h.walker/docsdiag/. Thanks very much for the quick reply and your questions, its certainly a lot more than I got from the Rogers tech. RogersJermaine. If no response is received, the modem logs another T3 timeout. If you keep getting dropouts on anything....call back in. T4 Timeout ( Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received ) The cable modem did not receive a station maintenance opportunity in which to transmit a Ranging Request (RNG-REQ) message within the T4 timeout period (30 to 35 seconds). 03:08 PM go to the connection tab and double check your power levels. 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. 10 days. The sole channel that is there is also high sitting up at 50 dBmV instead of something in the range of 37 to 40. Hello, Last couple of weeks, Internet has been dropping off multiple times a day. T4 (Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received) The cable modem did not receive a station maintenance opportunity in which to transmit a Ranging Request (RNG I would say the loss is hourly or close to it. - last edited on Sometimes it's working for 2 days without problems, and there are some days that I experience 5-7 resets per day ... Don't worry about "DHCP WARNING - Non-critical field invalid in response". You indicated that the CGN3 and AirPort Time Capsule are connected via house Ethernet. Now I finally got some useful answer from provider. 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. One of those times the phone might go dead in mid-conversation. Are you able to see the return path and downstream frequencies? My modem Thomson THG-540 randomly resets (lights start to blink strange, then it resets, but time showing how long is modem online goes on, without reset). The connection problem has virtually went away, I had another critiacl error show up again this morning. Upstream I was on the phone to the Rogers tech until 3:09AM last night and onto another tech this morning for an hour or so. Typically flapping (constant cycling) is a downstream power issue. Thanks agin for your help and rather informative trouble shooting. De connect box is bedraad aangesloten op een 'extra wifi punt ziggo'. Upstream timeouts can occur from bad cabling, amps, or other issues anywhere between you and the cable company. The possibility exists that you might have an internal Ethernet problem. could be old modem firmware as well. The download could be a different issue. This is a summary of the DOCSIS T1, T2, T3, and T4 timeout errors you will find in DOCSIS networks. I would gladly purchase a new router if that would resolve it. Atttempting continuous pings from that location to the home system shows packet loss at varying rates. It could prevent it from fully registering, but not flap. If it reads 100 Mb/s or less, you will probably see 30 to 40 Mb/s. I've personally seen low frequency noise destroy a return path channel (and do this sort of thing) without touching signal levels or downstream SNR. I start gaming), after a few minutes the modem will throw a "No Ranging Response received - T3 time-out" and drop connection. 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. I have Rogers’s bundled service, TV, home phone and Internet hybrid 50. I rebooted the modem and was back online. 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. I'm anxious to find out what is going on. 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. But I'm happy for now, that is working. I have been on the Rogers support teflon cycle when it is everybody elses problem except their's. 01:09 AM This error message is DOCSIS event message is R01.0, Ranging Request. Da ich öfters mit If you have a moody channel 521 or whatever (which is caused by the same physical signal problem), it's much easier to get that escalated and a tech out than a moody Internet problem... Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Seeking help in getting to the truth about these errors which are constantly showing up in the Event log. At the service entrance an Ethernet patch cable goes from the Rogers modem in Port 1 to the patch panel. Don't worry about the occasional one. receive levels should be zero (plus or minus 10, so between -10 and +10). Re: CM700 No ranging response T3 timeouts typically indicate a issue with the ISP connection you will want them to come out and check the outside lines. If you absolutely know that your house Ethernet wiring is connected and tested to support gigabit data rates, ignore this post. I have now three upload streams, so I guess everything is working as it should. There are no indications that inbound packets are lost. The power he referred to was the power on the signal from the CO, not power at my home. The fact that you are also having issues with the phone and tv would say to me, cabling or connector issue. I now ROUTINELY have intermittent signal loss. Go to Solution. Going to call them That is a fairly unhealthy looking connection with no upstream channels locked on and only one downstream channel when there should be eight. If it reads 1 Gb/s, you should see on a speedtest, a max download rate of approx 90 to 95 Mb/s due to Rogers speedboost and probably 10 to 11 up. The errors I get include the T3 timeouts, DHCP RENEW WARNING - Field invalid in response v4 option, CM certificate error, but also a new one that I haven't seen before, RNG-RSP CCAP Commanded Power in … My Event Log keeps showing many recurring instances of Critical (3) Priority: 16 consecutive T3 timeouts while trying to range on upstream channel x (where x=1-3) No Ranging Response received - T3 time-out. 10/23/2008 21.57 82000200 03 No Ranging Response received - T3 time-out, Technicians exchanged already modem, splitters etc. Before I received … To do that all 4 wire pairs within the cabling must be connected end to end. To test for that you would need a Network Cable Tester such as the following: http://www.lowes.ca/products/compare.aspx?sku=8777782,8781121. Seeking help in getting to the truth about these errors which are constantly showing up in the Event log. 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. We rebooted the modem which caused the power failure notice today, but last time we did not and both times we were down for 5-10 minutes. It is in gatweway mode. I did notice downstream light went to green (no DOCSIS 3.1 anymore) last night after my last post. : 410Mhz and US channel: 2, and when reset will happen, DS freq. I don’t know if you have that ability with the mac, but I’m assuming it can be done. Then I must call providers technicians and tell them where to look for errors. Re: No Ranging Response received - T3 time-out. I see that the link no longer works for some reason. 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. Now it's working without a problem for aprx. will be: 406Mhz (or something like that), and different US channel). Before I had a Motorola sb901 and now a sp6121. 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. :). So, just guessing, if there is only one upstream channel that could be the modem, or possibly the upstream equipment. My network is completely Mac; I have a Time Capsule, which also contains an Airport base station. Reading through you post again, I had a few thoughts on the speed issue. Does it always acquire the same downstream channel? Forum discussion: I recently upgraded to 30/2 from 15/1.5 in preparation for receiving my new Docsis 3 modem. Did tech support indicate that you should be expecting a visit from a tech? Error Event: No Ranging Response received - T3 time-out;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.0; Error type: 82000700. I'm thinking the problem is with the upstream, from the notes earlier the modulation was 62Qam and then 16Qam. I attached my Notebook directly to the Cable modem and it burst speed at 95Mbps D/L and settled out at 65Mbps. - edited When I do call this in, I will also have all my TVs on, at the diagnostic pages (Cisco 9865, Cisco 4642, SA4250HD, SA3100) , to ensure those are not adversely affected (Signal strength, S/N ratio) by any changes that are made to fix the intermittent connection issue. I'll keep my fingers crossed. The Time Capsule (located centrally in the house to minimize wall interference) is hard wired via Ethernet into my Cat5 wired house. Sometimes restarting the modem helps, but not always. I just checked again and realized my The dropouts are sometimes indicative or a cable or connector issue of some type, which might show up in the power levels. ‎07-18-2014 Not a big deal at all. in my house, but the problem remains. Re: Intermittent "No Ranging Response received - T3 time-out". Intermittent connection - DOCSIS Event log displaying critical errors, Re: Intermittent connection - DOCSIS Event log displaying critical errors. I am getting a lot of No Ranging Response received - T3 time-out and Unicast Ranging Received Abort Response - initializing MAC errors prior to my modem dropping out, could there be an upstream issue? I can't think of any reason why a bad DHCP server would make a modem do that. Try to reproduce the problem with some TV channels. 10:04 PM On the home system, running a tcpdump while pinging from the Comcast Fibre location, I see all pings coming into the system in order and all responses going out. ‎07-18-2014 The power levels are off which could indicate a cabling or connector issue. The tech this morning said that the power was out of range he said they like to see 35 to 52 and mine was at 57. 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. Only worry if you start to see a bunch of them. T3 and T4 timeouts are described in much more detail And I noticed one more thing: Upstream modulation should be QAM64, but sometimes I see it changes after reset to QAM16. http://www.lowes.ca/products/compare.aspx?sku=8777782,8781121. Modem flapping would be an RF issue anyway. 2015/6/2
14:31:01 Error. ... or must one go through the runaround first? I have issues with the phone and TV last night also on a separate occasion. you miss some Non critical field in dhcp response. This error message is DOCSIS event message is R03.0, Ranging Request. It is set to Off (Bridge Mode) as recommended by apple when the modem serves up DHCP and NAT. Put tech support on speed dial. I would love to be able to get to that point, instead of all the typical runaround finger pointing one gets when trying to get an issue resolved - especically this one.
