Troubleshooting Connectivity Issues

Introduction

Connectivity issues can arise in various networking environments, leading to service disruptions, slower speeds, or complete loss of access to applications or the internet. This guide provides common troubleshooting steps to help diagnose and resolve connectivity problems.

Check Physical Connections

Ensure all cables are securely connected.
Check if the Ethernet cable is plugged into the correct ports on both your device and the router.
For wireless connections, make sure Wi-Fi is enabled on your device.

Verify Router/Modem Power.

Ensure your modem or router is plugged into a working electrical outlet and that it is powered on. If the device has a power switch, ensure it's turned on.

Verify Internet Service

Test with Another Device.
Attempt to connect to the network with another device (e.g., smartphone, tablet) to verify if the issue is isolated to the original device.
Check for Service Outages.
Check with your Internet Service Provider (ISP) for any known service outages in your area.

Software-Based Solutions

Reboot the Computer or Device
Reboot Device:

Restarting your device (PC, smartphone, or tablet) can resolve temporary network glitches caused by software errors.
Disable VPN and Proxy Settings

Disable VPN:

A VPN (Virtual Private Network) can sometimes interfere with network connectivity. Disable the VPN and check if the connection is restored.

Check Proxy Settings:

Ensure that your device is not using an incorrect or outdated proxy server. You can disable proxy settings by following these steps:

On Windows: Go to Settings → Network & Internet → Proxy and disable it.

On macOS: Go to System Preferences → Network → Advanced → Proxies and uncheck any enabled options.
