Troubleshooting Network Connectivity on Windows/Linux

January 9, 2026

In our increasingly connected world, a single network hiccup can bring entire workflows to a halt.

Whether you're on Windows or Linux, knowing how to efficiently troubleshoot network connectivity issues is essential for maintaining productivity—especially in enterprise environments.

Whether it's a dropped remote desktop session, failed internet access, or a DNS resolution failure, resolving these issues quickly can save businesses both time and revenue.

At DirectDeals, where we've been helping businesses streamline their software and IT infrastructure for 26 years, we understand how vital connectivity is to operational success. This guide outlines how to diagnose and resolve common network issues across Windows and Linux systems while highlighting how the right tools—and the right licensing can enhance efficiency.

Common Network Connectivity Issues

Before jumping into the platform specific solutions, here are some common network problems users may face:

No internet connection
Intermittent connectivity
DNS resolution errors
Slow network speeds
IP conflicts
Firewall or security software blocking connections

Troubleshooting on Windows

1. Use Built In Network Troubleshooter

Go to Settings > Network & Internet > Status, and select “Network troubleshooter”.

This tool checks for basic issues such as DNS problems or gateway availability.

2. Run Command Line Diagnostics

ipconfig /all – View all network configuration settings
ping google.com – Check internet connectivity
tracert – Identify delays in network routing
netsh int ip reset – Reset TCP/IP stack

3. Check Firewall Settings

Ensure that Windows Defender Firewall or third party security software isn’t blocking essential ports or services.

4. Update or Reinstall Network Drivers

Using Device Manager, find the network adapter, update the driver, or uninstall and reinstall it. Often, a corrupt driver can cause issues that aren’t immediately obvious.

Troubleshooting on Linux

Linux provides more transparency and flexibility with command line tools:

1. Use ping and traceroute

ping -c 4 8.8.8.8 – Check if you're connected to the internet
traceroute google.com – Check for delays or blocks along the path

2. Check Network Configuration

Use ifconfig or ip a to check the IP assignment. Ensure that you're not using a loopback address or an incorrect subnet.

3. Restart Network Services

For Debian-based systems:

sudo systemctl restart NetworkManager

For Red Hat-based systems:

sudo systemctl restart network

4. Review DNS Settings

Check /etc/resolv.conf to make sure the DNS server addresses are correct.
