docsis no ranging response received

you miss some Non critical field in dhcp response. 2016/4/23 21:58:02 Firewall Blocked I just checked again and realized my If you have any doubts on the house Ethernet…..read on. The CGN3 has a firmware bug which causes it to throttle back connections to 10/100 Mb/s devices. Is there problem with DHCP server on my line? The cable was frayed and had water damage. I'm anxious to find out what is going on. 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. Error priority: critical. Am I correct? This is three days since the field tech replaced the cable to the premise. I'm willing to bet it's the tftp options. Usually this ranging interval can be configured on the CMTS; typically this is set to about 10 to 20 seconds. Re: No Ranging Response received - T3 time-out. 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. : 410Mhz and US channel: 2, and when reset will happen, DS freq. The process repeats until the modem and the CMTS establish communication at an acceptable level. That kinda gets the point accross. I see that the link no longer works for some reason. ‎07-18-2014 Now I finally got some useful answer from provider. In that case the problems are with the modem and RG6 cabling. 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. I can't think of any reason why a bad DHCP server would make a modem do that. Going to call them 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 would expect to see three upstream channels, not the single channel that it shows. Before I received … The download could be a different issue. Error type: 82000200. Had an engineer come around - 4365811 Time Priority Description 13/08/2020 11:26:33 critical No Ranging Try to reproduce the problem with some TV channels. What do you mean by: " you lost some field in dhcp server"? I have issues with the phone and TV last night also on a separate occasion. I now ROUTINELY have intermittent signal loss. 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. 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. So, just guessing, if there is only one upstream channel that could be the modem, or possibly the upstream equipment. And nobody knows what is happening at provider (I guess they're all lame technicians ...), Downstream The upload remained the same at 5.65Mbps. Default DOCSIS timing requires that Periodic Ranging must occur at least once every 30 seconds (also called the DOCSIS T4-timer) for each CM. Don't worry about the occasional one. Solved! The tech re-sets both and it has been working somewhat acceptable since. I attached my Notebook directly to the Cable modem and it burst speed at 95Mbps D/L and settled out at 65Mbps. 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 Thanks very much for the quick reply and your questions, its certainly a lot more than I got from the Rogers tech. 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. Any snow or audio distortion especially on the low channels? The fact that you are also having issues with the phone and tv would say to me, cabling or connector issue. 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. And I noticed one more thing: Upstream modulation should be QAM64, but sometimes I see it changes after reset to QAM16. ‎07-18-2014 I recommend you go and buy a new modem, best buy, office max, etc... Reading through you post again, I had a few thoughts on the speed issue. If you see multiple T3 timeouts in a single day, it's an indication that a less-than-optimal condition exists. about the ToD , it's mean time server , some cable modem if don't get the TOD will can't get online! Just ask! De connect box is bedraad aangesloten op een 'extra wifi punt ziggo'.

If you keep getting dropouts on anything....call back in. 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. 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). 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. Check as well the WAN uptime and see if it has reset to 0 when this drop occurs. Before I had a Motorola sb901 and now a sp6121. ... or must one go through the runaround first? Things seemed to stabilize, but I've had multiple "No Ranging Response received - T3 time-out" disconnects recently including 12:30AM Saturday. will be: 406Mhz (or something like that), and different US channel). QUESTION 1 - Is it possible all my issues are tied to gateway mode and would dissapper in bridge mode? Certainly a lot less than advertised, only 68% of the speed I signed onto. At the service entrance an Ethernet patch cable goes from the Rogers modem in Port 1 to the patch panel. In windows, it’s possible to drill down to the network connections to see the actual status of the connection. Only worry if you start to see a bunch of them. Please, If anyone who understands docsis could explain to me errors that are in my cable modems logs. Here are the links to the LAN testers: http://www.lowes.ca/test-meters-equipment/ideal-linkmastertrade-tester_g1199379.html. Solved! Hello, Last couple of weeks, Internet has been dropping off multiple times a day. - edited Then I must call providers technicians and tell them where to look for errors. 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. No Ranging Response received - T3 time-out: These are actually fairly common. 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. Did the upstream table not paste in entirely? 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). 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. [Dhcpc] [2491]: erouter0 got new IP X.X.X.X. 03:08 PM 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. in my house, but the problem remains. But I'm happy for now, that is working. I would say the loss is hourly or close to it. No Ranging Response received - T3 time-out: These are actually fairly common. Put tech support on speed dial. At -5 dB it 'should' be fine, but I've seen weirder stuff. 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 several 'standard' ways to define the tftp server name and config file in the dhcp config. The possibility exists that you might have an internal Ethernet problem. I'll attempt to respond to the questions. 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. Forum discussion: I recently upgraded to 30/2 from 15/1.5 in preparation for receiving my new Docsis 3 modem. I also connected modem to car battery to exclude power supply problem. Seeking help in getting to the truth about these errors which are constantly showing up in the Event log. 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. 22-02-2020 22:56 - edited ‎22-02-2020 22:57. Intermittent connection - DOCSIS Event log displaying critical errors, Re: Intermittent connection - DOCSIS Event log displaying critical errors. Only worry if you start to see a bunch of them.

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. 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. 10:04 PM Mijn TV en de appleTV zijn op hun beurt weer bedraad aangesloten op … 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. Power 46 dBmV. 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. Best regards from Slovenia, and thanks in advance for help! that way it's new and you don't have to lease it from your provider. Do you get cable TV through this connection? Can you tell if the modem is frequency hopping? 10 days. De NAS-disk is bedraad aangesloten op de connect box. 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. Typically flapping (constant cycling) is a downstream power issue. 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.

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 Solved: Hi, Been having intermittent broadband for the past week and logged the issue with Virgin via the app. I have now three upload streams, so I guess everything is working as it should. Thanks agin for your help and rather informative trouble shooting. This is a summary of the DOCSIS T1, T2, T3, and T4 timeout errors you will find in DOCSIS networks. 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. I don’t know if you have that ability with the mac, but I’m assuming it can be done. Please help me with THG-540 and my provider, http://homepage.ntlworld.com/robin.d.h.walker/docsdiag/. - last edited on You indicated that the CGN3 and AirPort Time Capsule are connected via house Ethernet. Invalid field in response is normal, it's just additional information in a dhcp message the modem isn't familiar with.

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. Did tech support indicate that you should be expecting a visit from a tech? 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. Now it's working without a problem for aprx. receive levels should be zero (plus or minus 10, so between -10 and +10). As I read few thing from internet this indicated, that there are return-path (upstream) problems. :). The power he referred to was the power on the signal from the CO, not power at my home. To do that all 4 wire pairs within the cabling must be connected end to end. It requires a number of misses before either happens. 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. Does it always acquire the same downstream channel? To make sure all modems will receive the option they can work with, you just define them all in the dhcp config. My download/upload speeds are great. De netwerkhistorie laat zien: No Ranging Response received - T3 time-out. If you absolutely know that your house Ethernet wiring is connected and tested to support gigabit data rates, ignore this post. 2015/6/2
