docsis no ranging response received

I just checked again and realized my Try to reproduce the problem with some TV channels. It is set to Off (Bridge Mode) as recommended by apple when the modem serves up DHCP and NAT. Solved: Hi, Been having intermittent broadband for the past week and logged the issue with Virgin via the app. RogersJermaine. Only worry if you start to see a bunch of them. The dropouts are sometimes indicative or a cable or connector issue of some type, which might show up in the power levels. Before I received … It is WiFi from the TimeCapsule out to multiple devices, iMac, MacBook Pro, MacBook, tablets, iPhones, Playstation, and audio receiver. Don't worry about the occasional one. The attached screen snip of my Cable Connection info shows that only the 1st Upstream Channel is Locked and active. The power levels are off which could indicate a cabling or connector issue. Power -5 dBmV Did tech support indicate that you should be expecting a visit from a tech? T3 and T4 timeouts are described in much more detail The connection problem has virtually went away, I had another critiacl error show up again this morning. 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. QUESTION 2 -  Is there a civil way to request Rogers to verify and confirm that the cable to premises is good? Before I had a Motorola sb901 and now a sp6121. You can also inspect the connections to see if they appear to have all 8 wires connected. I see that the link no longer works for some reason. There are no indications that inbound packets are lost. ‎07-18-2014 That is a fairly unhealthy looking connection with no upstream channels locked on and only one downstream channel when there should be eight. 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. Did the upstream table not paste in entirely? : 410Mhz and US channel: 2, and when reset will happen, DS freq. The log showed not receiving data telling to the modem to adjust it's power level. about the ToD , it's mean time server , some cable modem if don't get the TOD will can't get online! 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. Any snow or audio distortion especially on the low channels? Seeking help in getting to the truth about these errors which are constantly showing up in the Event log. Event Type Code: 24 8: 2020-12-11 03:32:24 82000400 critical Received Response to Broadcast Maintenance Request, But no Unicast I'm willing to bet it's the tftp options. 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 have the Hitron CGN3 with Hybrid Fibre 60/10 service. 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. The process repeats until the modem and the CMTS establish communication at an acceptable level. 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). It requires a number of misses before either happens. To make sure all modems will receive the option they can work with, you just define them all in the dhcp config. 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 … The CMTS and modem ping-pong as a way for the CMTS to Whenever the line comes under load (E.g. And I noticed one more thing: Upstream modulation should be QAM64, but sometimes I see it changes after reset to QAM16. 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. Error type: 82000200. So there must be problem at providers side. Best regards from Slovenia, and thanks in advance for help! 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. If it reads 100 Mb/s or less, you will probably see 30 to 40 Mb/s. [Dhcpc] [2491]: erouter0 got new IP X.X.X.X. 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. Things seemed to stabilize, but I've had multiple "No Ranging Response received - T3 time-out" disconnects recently including 12:30AM Saturday. 10/23/2008 21.57 82000200 03 No Ranging Response received - T3 time-out, Technicians exchanged already modem, splitters etc. Power 46 dBmV. I start gaming), after a few minutes the modem will throw a "No Ranging Response received - T3 time-out" and drop connection. 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). 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? If you keep getting dropouts on anything....call back in. I can't think of any reason why a bad DHCP server would make a modem do that. My download/upload speeds are great. I rebooted the modem and was back online. The ends are terminated with the best compression fittings in the industry and brand new. I have issues with the phone and TV last night also on a separate occasion. Re: No Ranging Response received - T3 time-out. Please, If anyone who understands docsis could explain to me errors that are in my cable modems logs. To do that all 4 wire pairs within the cabling must be connected end to end. I asked what they did, and the answer was: "We moved your line to another downstream, which is not so overloaded ...". De NAS-disk is bedraad aangesloten op de connect box. 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. Intermittent connection - DOCSIS Event log display... That's what we're here for! will be: 406Mhz (or something like that), and different US channel). Go to Solution. 2015/6/2
14:30:55 Notice. The cable modem is certified to work on any Euro-DOCSIS based HFC cable system and is certified Euro-DOCSIS 2.0 by Excentis"). But I'm happy for now, that is working. 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. 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 … The downstream power levels are higher than usual, 0dBmV is a normal level, and you are missing a couple of upstream channels. Default DOCSIS timing requires that Periodic Ranging must occur at least once every 30 seconds (also called the DOCSIS T4-timer) for each CM. I must keep calling cable company, they must repair my line ... 10/23/2008 21.57 68000300 03 DHCP WARNING - Non-critical field invalid in response. The fact that you are also having issues with the phone and tv would say to me, cabling or connector issue. Had an engineer come around - 4365811 Time Priority Description 13/08/2020 11:26:33 critical No Ranging I don't think the modem you have supports docsis 2.0. docsis 1.1 yes, but 2.0 I'm not sure. 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. could be old modem firmware as well. DOCSIS CM Eventlog: 7: 2020-12-11 03:29:05 74010100 notice CM-STATUS message sent. ‎07-18-2014 I don’t know if you have that ability with the mac, but I’m assuming it can be done. 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 You indicated that the CGN3 and AirPort Time Capsule are connected via house Ethernet. Mijn TV en de appleTV zijn op hun beurt weer bedraad aangesloten op … receive levels should be zero (plus or minus 10, so between -10 and +10).

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. - edited This is three days since the field tech replaced the cable to the premise. Now it's working without a problem for aprx. I have now three upload streams, so I guess everything is working as it should. Just ask! Do you get cable TV through this connection? That kinda gets the point accross. Typically flapping (constant cycling) is a downstream power issue. go to the connection tab and double check your power levels. Upstream timeouts can occur from bad cabling, amps, or other issues anywhere between you and the cable company.

Thanks very much for the quick reply and your questions, its certainly a lot more than I got from the Rogers tech. I would gladly purchase a new router if that would resolve it. Re: Intermittent "No Ranging Response received - T3 time-out". De netwerkhistorie laat zien: No Ranging Response received - T3 time-out. Is there problem with DHCP server on my line? Now I finally got some useful answer from provider. http://www.lowes.ca/products/compare.aspx?sku=8777782,8781121. [Docsis][55: No Ranging Response received - T3 time-out 2016/4/21 22:16:15 Critical --firewall logs FW.IPv6 INPUT drop, 431 Attempts. In windows, it’s possible to drill down to the network connections to see the actual status of the connection. If you have any doubts on the house Ethernet…..read on. Certainly a lot less than advertised, only 68% of the speed I signed onto. 10 days. 2016/4/23 21:58:02 Firewall Blocked 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. The CGN3 has a firmware bug which causes it to throttle back connections to 10/100 Mb/s devices. De connect box is bedraad aangesloten op een 'extra wifi punt ziggo'. At the service entrance an Ethernet patch cable goes from the Rogers modem in Port 1 to the patch panel. [Docsis] [690]: SW upgrade Failed after download - SW File corruption. 10:04 PM My network is completely Mac; I have a Time Capsule, which also contains an Airport base station.

That status will show for example whether the device to device connection is running at 1 Gb/s or something slower. 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. Don't worry about the occasional one. 01:09 AM DOCSIS timeout descriptions or errors and what they mean. ... or must one go through the runaround first? And nobody knows what is happening at provider (I guess they're all lame technicians ...), Downstream 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. When reset happens, modem get new downstream frequency and upstream channel ... (now is DS freq. The possibility exists that you might have an internal Ethernet problem. Signal to Noise Ratio 35 dB The goal of the Rogers Community is to help you find answers on everything Rogers. Those levels look normal. I also connected modem to car battery to exclude power supply problem. 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. This error message is DOCSIS event message is R01.0, Ranging Request. If you see multiple T3 timeouts in a single day, it's an indication that a less-than-optimal condition exists. Looking at the log, these two entries are repeating. by 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. It could prevent it from fully registering, but not flap. I'll attempt to respond to the questions. The tech re-sets both and it has been working somewhat acceptable since. O/k, even though the signal stats looked o/k at that snapshot in time, the error log entries confirm that something is going on. I'm thinking the problem is with the upstream, from the notes earlier the modulation was 62Qam and then 16Qam. 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). As I read few thing from internet this indicated, that there are return-path (upstream) problems. I now ROUTINELY have intermittent signal loss. Solved! Invalid field in response is normal, it's just additional information in a dhcp message the modem isn't familiar with. Going to call them Internet dropping off intermittently- No Ranging Response received - T3 time-out error. 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. Only worry if you start to see a bunch of them. DHCP WARNING - Non-critical field invalid in response. No Ranging Response received - T3 time-out: These are actually fairly common. 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 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. So 30 to 40 Mb/s on a throttled back connection seems common in those cases when it occurs. Sometimes restarting the modem helps, but not always. but i think it's ok. i think you can try http://homepage.ntlworld.com/robin.d.h.walker/docsdiag/ I have been on the Rogers support teflon cycle when it is everybody elses problem except their's. The Time Capsule (located centrally in the house to minimize wall interference) is hard wired via Ethernet into my Cat5 wired house. Looking at the tables a couple of things are evident. I'm anxious to find out what is going on. Solved! Reading through you post again, I had a few thoughts on the speed issue. The cable modem is resetting its cable interface and restarting the registration process. Am I correct? When I lost DOCSIS 3.1, dl speeds decreased 30-40%. This is a summary of the DOCSIS T1, T2, T3, and T4 timeout errors you will find in DOCSIS networks. It is in gatweway mode. 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. Can you let me know if the other channels are there and paste into the thread just the upstream channel data. 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). What do you mean by: " you lost some field in dhcp server"? Does it always acquire the same downstream channel? 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. I checked the dowstream/upstream summaries and they look normal. 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. Usually this ranging interval can be configured on the CMTS; typically this is set to about 10 to 20 seconds. 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.

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. No. In that case the problems are with the modem and RG6 cabling. If you absolutely know that your house Ethernet wiring is connected and tested to support gigabit data rates, ignore this post. I did notice downstream light went to green (no DOCSIS 3.1 anymore) last night after my last post. Atttempting continuous pings from that location to the home system shows packet loss at varying rates. 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. Upstream Put tech support on speed dial. 2015/6/2
14:31:01 Error. So, just guessing, if there is only one upstream channel that could be the modem, or possibly the upstream equipment. Here are the links to the LAN testers: http://www.lowes.ca/test-meters-equipment/ideal-linkmastertrade-tester_g1199379.html. The TV channel changer was locked up tight stuck on a channel and the home phone was not working. Thanks agin for your help and rather informative trouble shooting. Can you tell if the modem is frequency hopping? 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. There are also a lot of errors and critical messages. - last edited on Event Type Code: 7; Chan ID: 3; DSID: N/A; MAC Addr: N/A; OFDM 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. Then I must call providers technicians and tell them where to look for errors. 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? 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.

Are you able to see the return path and downstream frequencies? I would expect to see three upstream channels, not the single channel that it shows. ‎03-19-2015 22-02-2020 22:56 - edited ‎22-02-2020 22:57. So, if you can, disconnect your Time Capsule from the wall Ethernet port and connect one of your gigabit capable devices directly to that port so that it picks up an address from the CGN3 and has an internet connection. I have Rogers’s bundled service, TV, home phone and Internet hybrid 50. Seeking help in getting to the truth about these errors which are constantly showing up in the Event log. 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 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. Error priority: critical. At -5 dB it 'should' be fine, but I've seen weirder stuff. Forum discussion: I recently upgraded to 30/2 from 15/1.5 in preparation for receiving my new Docsis 3 modem. Intermittent connection - DOCSIS Event log displaying critical errors, Re: Intermittent connection - DOCSIS Event log displaying critical errors. "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. The cable was frayed and had water damage. Da ich öfters mit 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. I would say the loss is hourly or close to it. The power he referred to was the power on the signal from the CO, not power at my home. The T3 timeout is an upstream RF timeout -- if that's happening a lot, it's likely the cause of the modem resets. First, a little explanation. you miss some Non critical field in dhcp response. 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. Perhaps there is intermittent noise ingress into the line (s) somewhere. that way it's new and you don't have to lease it from your provider. The download could be a different issue. If no response is received, the modem logs another T3 timeout. 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 this is mean you lost some field in dhcp server. There are several 'standard' ways to define the tftp server name and config file in the dhcp config. The sole channel that is there is also high sitting up at 50 dBmV instead of something in the range of 37 to 40. please let me know how you make out. 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. to get more current information in the cable modem . in my house, but the problem remains. Not a big deal at all. 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. I'll keep my fingers crossed. 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). 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.
