You can open Netstat by typing the following command and pressing ENTER:

You may not understand what the columns mean if you’re new to networking.

The netstat command shows you your active connections and their details. However, you’d notice that the foreign address column prints the IP address and port names.

To show the connections’ port numbers instead of the port names next to the IP addresses, use the following command:

Further, the system can disconnect or connect to networks, and the network details can change at intervals. Hence, we can use the following command to refresh the netstat network details at intervals using this command:

To stop the refreshing, press the CTRL + C key combination.

NOTE: The 5 in the command above refreshes the command every 5 seconds. If you wish to increase or shorten the interval, you can modify this value.

The netstat command is a powerful command that can show you every detail about your device’s connections. Explore the most commonly used netstat parameters to find specific network details.

Show the networks that are active or inactive.

List all applications that are associated with the connections.

Show statistics on incoming and outgoing network packets.

If you don’t want to see the port numbers or names, the following netstat parameter will show your foreign addresses’ fully qualified domain names.

Change the foreign address port names to port numbers.

Similar to netstat, and it has an extra column for every connection’s Process ID (PID).

Display the connections for the protocol you specify – UDP, TCP, tcpv6, or udpv6.

NOTE: You should change the udp part to the protocol whose connections you want to view.

Show connections and their listening and bound non-listening ports.

Categorize networks by available protocols – UDP, TCP, ICMP, IPv4, and IPv6.

Show the routing table of your current network. It lists every route to the destination and matrix available on your system. Similar to the route print command.

Show a list of connection offload states of your current connection.

Shows all NetworkDirect connections.

Show your networks’ TCP connection templates.

You can further filter the Netstat parameters to show you information about your connections any way you want. From the above commands, you only have to add a second parameter to show a combined view.

For instance, you can combine the -s and -e parameters to view the statistics for every protocol. This way, you can combine other parameters to get the desired results.

When mixing multiple Netstat parameters, you don’t need to include two dashes (-). You can use one dash (-) and append the parameter letters without a second one.

For example, instead of typing the following command:

You can write it as:

If you forget the parameters, a quick way to remember them is by asking netstat to help. Simply run the following command:

netstat /?

To stop the netstat query process, press the CTRL + C key combination.

We can check network connectivity using the netstat or network statistics command. This allows us to see active network connections and their status. The tool can view incoming and outgoing network connections, routing tables, port listening, and usage statistics. This command can be handy for network administrators when troubleshooting network issues. By understanding how to use this command, you can quickly and efficiently diagnose problems with your network.

You can check your network connection status in Windows quickly and easily. Select the Start button to do so and type “settings” into the search bar.

This problem is most likely to be associated with your network adapter drivers. As we know, faulty and out-of-date drivers are known to cause various errors and issues on the system. If the scenario applies to you, you should try updating your network adapter drivers and see if the problem is fixed.

You can manually update drivers in Windows 11/10 or use a free third-party driver updater to update drivers automatically. Besides that, you can also visit the official website of the manufacturer and download the latest version of your drivers from there. I would recommend you to opt for the latter method.

After updating your network adapter drivers, reboot your PC and then check if the issue is fixed or not. If not, move on to the next potential fix to resolve the error.

Some users have suggested that the problem is caused due to their firewall. It might be interfering with your system and leading to the “Not connected, No connections are available” error notification. If that is the case, you can try disabling your firewall temporarily to fix the problem.

To disable your firewall, simply open the Windows Defender Firewall and then select the Turn Windows Defender Firewall on or off option from the left panel. Now, choose the Turn off Windows Defender Firewall (not recommended) option for both Private and Public networks. If the problem is resolved after doing so, your firewall was the main culprit. To fix the issue, you will have to change some settings in your firewall. If that doesn’t help, maybe it’s time to consider some other firewall software for your system.

Flushing the DNS cache clears IP addresses and other DNS records from your system. This action is helpful in many cases, like when you are experiencing network issues. If the problem still persists, we suggest you flush your DNS cache and see if it helps.

There might be some problematic application on your PC that is interfering with your network connections. It could be your third-party antivirus, firewall, or some other third-party suite. Some users have reportedly faced this problem with Zone Alarm Firewall and they were able to fix the issue by uninstalling it.

You can try troubleshooting the problem in a clean boot state. Perform a clean boot and then check whether the problem is resolved. If yes, the problem is most likely caused by software conflicts. You will have to remove the software causing the conflicts to resolve the problem. You can manually uninstall the programs via the Settings app, or use a free software uninstaller to completely remove the program.

To start your system in a Clean Boot state, you have to disable all the third-party apps and services via MSConfig. After starting your system in the Clean Boot state, check if you can access the internet or get the same error. If the error does not occur in the Clean Boot state, any third-party software or service is the culprit. Now, enable some of the startup apps and services, and start your system in a normal state. See if the problem persists. If yes, one of the startup apps and services that you have just enabled is the culprit. In this way, you can identify the problematic third-party app and service.

If your Windows 11 PC is unable to connect to a network, make sure the problem is system-related, not network-related. Try connecting to the same network on a different device like your mobile and see if you are able to connect to the network. If you are able to connect to the network on other devices, the problem is with your system. You can try rebooting your computer, adding the network again, disabling the firewall, updating your Windows, rolling back your driver, or running the Network troubleshooter.
