No ranging response received – T3 Time-out error is the most common error that you will receive if you are using a cable modem. This “T3 Time–Out error can be caused due to weak modem, damaged cables, wrong device configuration, and poor internet wiring.
In this post, we are going to discuss the causes and solutions to fix the “No ranging Response Received – T3 Time–out” error.
Why Are You Getting No ranging Response Received – T3 Time–out” error?
Temporary issues With Your Router: It’s possible that there is some temporary glitch with your router which is causing the issue.
- Faulty Modem: If you are using an old and outdated modem, chances are high that you will face these errors more frequently. Internet connection totally depends on your modem’s ability to send ranging requests to CMTS, and this process gets affected if you are using a faulty Modem.
- Upstream Noise: Upstream channel sends messages from the modem to CMTS and the downstream receives messages from the ISP. Any disturbance due to poor grounding, faulty hardware, and loose connections will create unwanted noises within the upstream channel.
- Use of Damaged or substandard Cable: It is not very prevalent but in some cases, people use Damaged or lower standard cables which result in T3 time-out error. The wires that we use for data transfer contain many tiny wires and damage to any of these will affect the data transfer.
- Poor Wiring: Bad wiring can cause this issue as the cable modem will not be able to communicate with CMTS. The modem will not be able to establish a connection since CMTS will not receive any ranging requests due to bad wiring.
- Incorrect Device Configuration: In most cases, the modem comes programmed with your account information. But there are some ISPs which might not be configured to the modem which you need to figure out individually. In such cases, you end up setting up the modem incorrectly.
