Quick Fixes

Replacing Damaged Cables

Now is the time to check the cables and wires of the setup. If there are any types of damaged or broken wires and cables or the cables are extremely low in quality, there are higher chances that the data transmission is disrupted. This ultimately leads you towards a ranging response received T3 time-out error.

Moreover, because broken cables are more prone to wear out and get oxidized because of coming in contact with the air, one of the most commonly occurring reasons for these errors is broken cables. Fixing the old wires is not really effective because they are prone to damage. Alternatively, you have the option of going with new wires and purchasing better and higher-quality cables for modem and router connectivity setups.

Checking for Service Outage

This is another major problem that can lead you towards the problem of no ranging response received. Look for whether there is a service outage problem in your area or not. You can use Xfinity Status Center or Downdetector for that.

This is because a service outage in your region could be the primary reason for the error, like no ranging response received. Remember this because service disruptions or service outages never occur with a warning.

Fixing Router And Modem Wiring

Another common problem is the issue with your modem and router wiring, which can lead you to this error. You need to keep an eye on the connections and wires because if there is any faulty wiring, there is a high chance that your modem will be unable to connect to the internet.

What is the first and foremost step that you have to take when you face this error?

The first and foremost important thing that you have to keep in mind is to make sure that all the connections are direct. They should not be interrupted with interruptions like joint turns or hinges. Ensure there are minimum splitters.

Is T3 time-out normal?

In case the cable modem is not raising the upstream transmit power level to a certain level to allow communication within the timeout period, there are chances that this may occur. This usually occurs because of problems in the Wi-fi network, damaged splitter, weak signals, misconfigured CMTS, and upstream noise.
