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. Going to call them So 30 to 40 Mb/s on a throttled back connection seems common in those cases when it occurs. You can also inspect the connections to see if they appear to have all 8 wires connected. 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 start gaming), after a few minutes the modem will throw a "No Ranging Response received - T3 time-out" and drop connection. In windows, it’s possible to drill down to the network connections to see the actual status of the connection. [Dhcpc] : erouter0 got new IP X.X.X.X. Error priority: critical. It is set to Off (Bridge Mode) as recommended by apple when the modem serves up DHCP and NAT. 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?

This error message is DOCSIS event message is R01.0, Ranging Request. 01:09 AM The process repeats until the modem and the CMTS establish communication at an acceptable level. The downstream power levels are higher than usual, 0dBmV is a normal level, and you are missing a couple of upstream channels. Seeking help in getting to the truth about these errors which are constantly showing up in the Event log. Go to Solution.

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). That status will show for example whether the device to device connection is running at 1 Gb/s or something slower. Don't worry about the occasional one. 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. will be: 406Mhz (or something like that), and different US channel). Upstream De NAS-disk is bedraad aangesloten op de connect box. I did notice downstream light went to green (no DOCSIS 3.1 anymore) last night after my last post. But I'm happy for now, that is working. I rebooted the modem and was back online. Before I received … [Docsis] : SW upgrade Failed after download - SW File corruption. ... or must one go through the runaround first? 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. 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 have issues with the phone and TV last night also on a separate occasion. At -5 dB it 'should' be fine, but I've seen weirder stuff. 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. Just ask! Does it always acquire the same downstream channel? Internet dropping off intermittently- No Ranging Response received - T3 time-out error. 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. Solved! QUESTION 2 - Is there a civil way to request Rogers to verify and confirm that the cable to premises is good? I recommend you go and buy a new modem, best buy, office max, etc...

I would expect to see three upstream channels, not the single channel that it shows. When I lost DOCSIS 3.1, dl speeds decreased 30-40%. That T-3 timeout is the CM not hearing back from the CMTS when it should. The CMTS and modem ping-pong as a way for the CMTS to I attached my Notebook directly to the Cable modem and it burst speed at 95Mbps D/L and settled out at 65Mbps. 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. 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. 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. I'm anxious to find out what is going on. to get more current information in the cable modem . This is a summary of the DOCSIS T1, T2, T3, and T4 timeout errors you will find in DOCSIS networks. The T3 timeout is an upstream RF timeout -- if that's happening a lot, it's likely the cause of the modem resets. 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. Did tech support indicate that you should be expecting a visit from a tech? 2015/6/2 14:31:01 Error. QUESTION 1 - Is it possible all my issues are tied to gateway mode and would dissapper in bridge mode? Not a big deal at all. Am I correct? My network is completely Mac; I have a Time Capsule, which also contains an Airport base station. 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. RogersJermaine. 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. 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.

Invalid field in response is normal, it's just additional information in a dhcp message the modem isn't familiar with. I also connected modem to car battery to exclude power supply problem. 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. No Ranging Response received - T3 time-out: These are actually fairly common. It could prevent it from fully registering, but not flap. Only worry if you start to see a bunch of them. 03:08 PM The cable modem is resetting its cable interface and restarting the registration process.
