![]() Cable modems periodically send range requests to the cable service provider’s equipment in these networks to establish and maintain connectivity. ranging ) RNG - RSP ( continue ) RNG - RSP ( success ) Remove CM from Remove. Technically speaking, cable modem systems frequently use the T3 timeout range response received error, especially when discussing DOCSIS (Data Over Cable Service Interface Specification) networks. Therefore, the error message reads, No Ranging Response received. Internet is essential nowadays and such instable service is completely unacceptable. received RNG - REQ No Yes No Retries exausted Retries exausted Parameters. Unfortunately, if it does not respond to any of the sixteen requests sent by the modem, we see a T3 timeout. I hope the next tech knows what the problem can be and resolve it. The chat agent can do nothing remotely rather than to make an appointment. Resetting your modem and replacing damaged wires can help fix no ranging response received errors. Based on my research online, this is related to the communication between the modem and CMTS and/or some configuration issues with the CMTS. T3 time-out errors can be caused by damaged cables, weak modem power, poor internet wiring, wrong device configuration, and lousy internet signals. I contacted Fido again last night when it happened again and another appointment was scheduled. This reminds me on the first day I hooked the Fido modem with residential gateway enabled, it's only assigned a IPv6 but not IPv4 so I could barely use it, until the next day it's fixed by itself. Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out. ![]() Warning (5) MIMO Event MIMO: Stored MIMO-1 post cfg file MIMO-1. Ive carefully examined the cable run through the house, to the outside, and up to the cable grip at my eve where it is tensioned to the box on the utility pole, removed extraneous cable. This never happened when I was with other cable internet providers that all use Rogers cable. No Ranging Response received - T3 time-out. I see a lot of 'sync timing synchronization failure' and 'no ranging response received' in my modems diag logs (included below, along with connection info). My Cable runs from the street to the house and a direct line to a -3db 2 way splitter to the TV box and the modem. I notice that after the modem rebooted and all lights turn to normal condition, I still have to wait for couple minutes to get internet back because my router shows " Your ISP's DHCP does not function properly.". In tracing it back to the Modem and times, these are seeming to occur around the nefarious 'SYNC Timing Synchronization failure' and 'No Ranging Response received' as seen below in the logs. The only thing I can do to bring the internet back is to reboot the modem. But I was not able to connect/ping anywhere. Exactly the same symptoms: modem status (lights, status in the portal) looks good, router status shows even I am still connected with an external IP address. Then on 12/10 the disconnection happened again at night. He said there were some similar cases in the neighbourhood so he would suggest to check the boxes beside the street, and he said that can be done remotely (is that true?).Īfter the modem was replaced, I didn't notice any difference when everything works.
