WEEK 5: PING Network Cable - M199205zn/Datacomm-CS3 GitHub Wiki

You can perform a basic network cable check using the ping command to verify connectivity. Follow these steps:

Steps to Check a Network Cable Using `ping`

1. Open Command Prompt

Press Win + R, type cmd, and press Enter.

2. Run a Ping Test

Ping a Known Device on Your Network (Router, PC, or Server)
```
ping -n 5 192.168.1.1
```
(Replace 192.168.1.1 with your router’s IP address)
If responses show "Reply from...", the cable is likely working.
If it shows "Request timed out", the cable might be faulty or disconnected.

Ping an External Server (Google’s DNS)
```
ping -n 5 8.8.8.8
```
If there are replies, the network cable is functioning.
If it shows "Destination host unreachable" or "Request timed out", check the cable or connection.

3. Check for Packet Loss

If the response includes:

Packets: Sent = 5, Received = 5, Lost = 0 (0% loss)

The cable is fine.

If there is packet loss, the cable may be damaged or loose.

Additional Checks

Try another cable if no response.
Use another port on the router or switch.
Check for loose connections at both ends.

This method quickly determines if a network cable is working or faulty using a simple ping test. 🚀
