If you don’t know how to deal with them, network issues are one of those things that can get extremely annoying. The worst part? You don’t even know what’s causing it. Over the years, I’ve been using these Windows network commands to troubleshoot most issues with ease.
ping: Check your connectivity
Say you’re staring at a browser that refuses to load anything, your Wi-Fi icon says everything’s fine, and you’re wondering whether your computer, your router, or the entire internet has simply given up. When I hit that moment, my first move is always the same. I use the ping command .
For example, if you want to figure out if your Wi-Fi is actually working, simply ping your router like this:
ping 192.168.1.1If you get replies, your local network’s alive. If not, you’ve found the problem. Not sure whether a website is down or if it’s just you? Ping a reliable server. Google is the classic.
ping google.com
Behind the scenes, ping sends tiny packets of data to your target and waits for them to come back.
ipconfig: Display your IP configurations
There are days when your connection breaks, not because the internet is down, but because your computer is confused. Wrong IP, no IP, stuck on an old network, or just refusing to pick up a new one. That’s when ipconfig becomes your best friend.
Need to see what IP address your computer has? Just run this command:
ipconfigThis gives you your IPv4 address, default gateway, DNS servers. For a more detailed view, you can run:
ipconfig /all
It displays detailed network configuration information for all network adapters, including the MAC address, IP address, subnet mask, default gateway, and DNS servers. If you’re facing a weird network-in-limbo issue, try running these commands:
ipconfig /release
ipconfig /renewA quick reset often fixes it. This forces Windows to drop its current IP and request a fresh one from the router.

nslookup: Perform DNS lookups
You know those times when your connection is clearly working. You can ping Google, you can access random sites. However, a specific website refuses to load. Or maybe apps can’t connect even though your browser is fine. Nine out of ten times, that’s a DNS problem, and that’s when I pull out nslookup.
If you’re figuring out whether a site’s name is resolving properly, you can run this command:
nslookup example.com
If DNS is healthy, you’ll get an IP address back. If not, it’ll either hang or return an error, instantly telling you that the issue isn’t with the site, but with your DNS. If you’re already suspecting that your DNS server is the culprit, try a different one, such as Cloudflare or Google.
nslookup example.com 1.1.1.1
nslookup example.com 8.8.8.8If those return results but your default DNS doesn’t, you’ve just proved the problem is local.
How to Find Your IP Address From CMD (Command Prompt)
To find your local IP address from the CMD Command prompt, simply type “ipconfig” into the prompt.
netstat: Display active connections
Ever felt that your network is slow, or some app is acting suspiciously? That’s when I lean on netstat. It’s a way of peeking behind the curtain to see what connections are active right now. To check for active network connections run this command:
netstat
It shows a list of all current connections: which remote IPs your computer is talking to, on what open ports, and the connection state. It’s like seeing all the open lines of communication at a glance. Let’s say you didn’t start a program that’s using the network. Run this:
netstat -anoThis adds the process ID (PID) for each connection, letting you match it to a running process in Task Manager. If some shady connection appears, you can investigate further.
tracert: Trace data packet routes
Sometimes you open a website, and it takes forever to load. Is it your Wi-Fi? Your ISP? Or some distant server on the other side of the world? That’s when I reach for tracert. To find where the slowdown is happening, I run:
tracert example.com
Windows will show each hop your data takes from your PC to the destination, along with the time it takes for each leg. You can quickly spot if your router, your ISP, or some faraway server is the problem. If a website isn’t loading, tracert can show you exactly where the connection stops.

netsh: Advanced network configuration
The other tools I mentioned are great for one-off tasks. But netsh, on the other hand, is like the Swiss Army knife of Windows networking. This command can do a little bit of everything. Resetting network adapters, tweaking Wi-Fi settings, configuring firewalls, and more.
When Windows networking gets really stubborn, a full network reset often does the trick:
netsh int ip reset
netsh winsock resetThis wipes out corrupted TCP/IP or Winsock settings and basically gives your network a fresh start. If you want to manage Wi-Fi profiles, like forgetting a network or seeing all the saved ones, run these commands:
netsh wlan show profiles
netsh wlan delete profile name="NetworkName" It’s perfect for clearing out old or problematic Wi-Fi credentials without digging through multiple menus. You can also use netsh to see what IPs and stats your adapters are using in real time.
netsh interface ip show config 
It’s basically a more advanced, interactive version of ipconfig. Great for troubleshooting when standard tools aren’t enough.
Windows networking doesn’t have to be a black box. With the commands I’ve shared, you can diagnose, troubleshoot, and many times fix most common connectivity issues yourself. Like the above ones, there are many other useful Windows commands for you to explore.
