🌐 2. Most Useful CMD Network Commands

Command Prompt remains one of the most useful tools for diagnosing Windows network problems.

Check IP Address

ipconfig

For detailed information:

ipconfig /all

Look for:

• IPv4 Address
• Subnet Mask
• Default Gateway
• DNS Servers
• DHCP Server
• Physical/MAC Address

The /all option is particularly useful because it provides much more information about the network adapter and how the computer received its configuration.

🔄 3. Renew an IP Address

If a computer is not receiving the correct IP address from DHCP, try:

ipconfig /release

Then:

ipconfig /renew

/release releases the current DHCP-assigned address, while /renew requests a new address from the DHCP server.

When is this useful?

Use these commands when:

• The computer has no valid IP address
• The computer received an incorrect IP configuration
• DHCP appears to be having problems
• The computer cannot communicate with other devices on the network

🧹 4. Clear the DNS Cache

If websites or internal servers are not resolving correctly, clear the local DNS cache:

ipconfig /flushdns

This removes cached DNS entries from the computer and forces Windows to perform new DNS lookups.

Also useful

To view the current DNS cache:

ipconfig /displaydns

🔍 5. Check Network Connectivity

Start with an Internet IP address:

ping 8.8.8.8

Then test a hostname:

ping google.com

Quick diagnosis

Result	What it may indicate
8.8.8.8 works, google.com fails	DNS is a likely area to investigate
Both fail	Check gateway, LAN/Wi-Fi, router, ISP or firewall
Gateway fails	Investigate local network connectivity
Gateway works, 8.8.8.8 fails	Investigate Internet connection, routing or firewall

Important: A failed ping to a website does not necessarily mean the website is down. Some servers block or ignore ICMP ping requests.

🧭 6. Find Where the Connection Is Failing

When troubleshooting a network problem, don't immediately reset everything. Work from the computer outward.

Check the Default Gateway

First run:

ipconfig

Find the Default Gateway.

Then ping it:

ping 192.168.1.1

Replace 192.168.1.1 with the actual gateway shown on the computer.

If the gateway responds, the computer can communicate with the local router or network.

If it does not respond, investigate the Ethernet/Wi-Fi connection, network adapter, cable, switch, VLAN, or gateway.

Trace the Network Route

Use:

tracert google.com

tracert shows the network hops between your computer and the destination.

It can help identify where traffic appears to stop or where routing problems may be occurring.

For a more detailed route and packet-loss analysis, use:

pathping google.com

pathping combines features of ping and tracert and can provide packet-loss and latency information for individual network hops.

🔎 7. DNS Troubleshooting

Find the IP Address of a Domain

nslookup google.com

To query a specific DNS server:

nslookup google.com 8.8.8.8

This is particularly useful when comparing your company's DNS server with a public DNS server.

For example, if the company's DNS server fails to resolve a name but a public DNS server succeeds, DNS configuration or the internal DNS server may need investigation.

View DNS Cache

ipconfig /displaydns

Clear the cache with:

ipconfig /flushdns

🔌 8. Check Network Connections and Ports

View Active Connections

netstat -ano

This displays active connections, listening ports and associated process IDs.

Show listening ports

netstat -ano | findstr LISTENING

Find a particular port

For example, to look for HTTPS:

netstat -ano | findstr :443

The last number is the PID (Process ID).

You can then identify the process:

tasklist | findstr 1234

Replace 1234 with the actual PID.

This can be useful when investigating which Windows application is using a particular network connection or port.

🔌 9. Advanced Network Diagnostics

View the ARP Table

arp -a

Displays the computer's ARP cache, showing IP addresses and their corresponding MAC addresses on the local network.

Useful for investigating local-network communication and checking how Windows has mapped local IP addresses to MAC addresses.

View the Routing Table

route print

Displays Windows routing entries, gateways and network interfaces.

This is particularly useful when troubleshooting:

• Multiple network adapters
• VPN connections
• Incorrect gateways
• Unusual routing problems
• Systems with more than one network path

🛜 10. Wi-Fi Technician Commands

Windows provides several netsh commands that are useful when troubleshooting wireless connections.

Show Saved Wi-Fi Networks

netsh wlan show profiles

Displays wireless network profiles saved on the computer.

Show Current Wi-Fi Information

netsh wlan show interfaces

Shows information about the current Wi-Fi connection, including:

• SSID
• Signal strength
• Radio type
• Channel
• Authentication
• Connection state

Show Wi-Fi Driver Information

netsh wlan show drivers

Displays detailed information about the installed wireless adapter and its supported capabilities.

Generate a Wi-Fi Report

netsh wlan show wlanreport

Creates a detailed Windows Wi-Fi report containing recent wireless connection events and troubleshooting information.

This can be particularly useful when diagnosing intermittent Wi-Fi connections, repeated disconnections, or wireless authentication problems.

🧰 11. Windows Network Reset Commands

When networking is badly misbehaving, these commands are commonly used during troubleshooting.

Reset Winsock:

netsh winsock reset

Reset the TCP/IP stack:

netsh int ip reset

Clear the DNS cache:

ipconfig /flushdns

Restart Windows afterward.

⚠️ Don't reset everything immediately

Network reset commands should generally not be your first troubleshooting step.

First determine whether the problem is related to:

• Network adapter
• DHCP
• IP configuration
• Default gateway
• DNS
• Routing
• Firewall
• Wi-Fi
• Application-specific connectivity

Resetting network components without identifying the problem can make troubleshooting more difficult.

⚡ 12. PowerShell Network Commands

PowerShell provides more detailed networking information and is especially useful for IT technicians.

Show IP Configuration

Get-NetIPConfiguration

Displays network configuration information for the computer.

Show Network Adapters

Get-NetAdapter

Shows network adapters and their status.

Show Detailed Adapter Information

Get-NetAdapter | Format-List

Displays more detailed information about the network adapters.

Test Network Connectivity

Test-NetConnection google.com

Useful for testing connectivity to a destination.

Test a Specific TCP Port

Test-NetConnection servername -Port 443

This is one of the most useful PowerShell commands for technicians because it can test whether a particular TCP service is reachable.

For example, to test SMB:

Test-NetConnection 192.168.1.50 -Port 445

This can help determine whether SMB connectivity is available between two systems.

🚨 14. A Simple Windows Network Troubleshooting Sequence

When someone says:

“The Internet isn't working.”

Don't immediately reset the router, change random settings, or reinstall network drivers.

Instead, work through the problem step by step.

The goal is to identify where the connection is failing.

Step A - Check the Physical or Wi-Fi Connection

Start with the basics:

• Is the Ethernet cable connected?
• Is the network adapter enabled?
• Is Wi-Fi connected to the correct network?
• Does Windows show an active network connection?
• Are other devices experiencing the same problem?

Use:

ncpa.cpl

This opens Network Connections, where you can check the status of Ethernet and Wi-Fi adapters.

Step B - Check the Computer's IP Configuration

Run:

ipconfig /all

Check whether the computer has:

• A valid IP address
• Subnet mask
• Default gateway
• DNS server
• DHCP information

Watch for 169.254.x.x

If the computer has an address such as:

169.254.x.x

it may not have received an IP address from the DHCP server.

Investigate the network connection, DHCP service, adapter, cable, Wi-Fi or network configuration.

Step C - Ping the Default Gateway

Find the Default Gateway from:

ipconfig /all

Then run:

ping <gateway>

For example:

ping 192.168.1.1

What this tells you

If the gateway responds, the computer can communicate with the local router/network.

If it doesn't respond, investigate:

• Ethernet cable
• Wi-Fi connection
• Network adapter
• Switch
• VLAN
• Local network
• Gateway/router

Step D - Ping an Internet IP Address

Run:

ping 8.8.8.8

This tests Internet connectivity without depending on DNS name resolution.

Possible results

Gateway works + 8.8.8.8 works

Internet connectivity is probably available.

Gateway works + 8.8.8.8 fails

Investigate the router, ISP connection, routing or firewall.

Step E - Test DNS

Run:

nslookup google.com

This checks whether DNS can resolve the domain name.

If 8.8.8.8 responds to ping but nslookup google.com fails, investigate DNS configuration or the DNS server.

Step F - Test a Domain Name

Run:

ping google.com

This tests both name resolution and network connectivity to the resolved address.

If:

ping 8.8.8.8

works but:

ping google.com

fails, DNS is a likely area to investigate.

Note: A failed ping to a website does not necessarily mean the website is unavailable. Some servers block or ignore ICMP ping requests.

Step G - Trace the Route

Run:

tracert google.com

tracert shows the network hops between your computer and the destination.

It can help identify where traffic appears to stop or where routing problems may be occurring.

🔄 Quick Network Diagnostic Flow

When troubleshooting a basic Internet connection, work through the following sequence:

Physical / Wi-Fi connection

          ↓

     ipconfig /all

          ↓

     Ping gateway

          ↓

     ping 8.8.8.8

          ↓

     nslookup google.com

          ↓

     ping google.com

          ↓

     tracert google.com

The purpose is to move from local connectivity → IP configuration → gateway → Internet → DNS → destination → routing.

📊 What the Results Can Tell You

Test	If it fails	Possible area to investigate
Physical/Wi-Fi	No connection	Cable, Wi-Fi, adapter, switch
ipconfig /all	No valid IP/gateway	DHCP, adapter, network configuration
