Netstat (Network Statistics) is a command-line tool for monitoring and troubleshooting computer network issues. This tool shows you all your device’s connections in as much detail as you need.

With Netstat, you can view all your connections and their ports and stats. This information is valuable when setting up or fixing your connectivity. This article will introduce you to the Netstat command and the main parameters for filtering information displayed about your connections.

We’ll explore the following syllabus in this section:

  1. How to use the Netstat command.
  2. Use netstat parameters to filter connection information.
  3. Combining Netstat parameters.

Join me as we go through the above syllabus to help you better understand this tool and learn how to use it to troubleshoot your network issues.

1] How to use the netstat command

netstat command

Click on the Start button and search for Command Prompt. Open Command Prompt with elevated privileges by right-clicking on it and selecting the Run as administrator option.

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.

  • Proto: The network protocol. It could be either TCP or UDP.
  • Local Address: The IP addresses and ports of your computer’s network interfaces for the given connections.
  • Foreign Address: The IP addresses and port names of the remote devices.
  • StateIndicates the state of the connection. For example, find out active and closed connections.

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:

netstat -n

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:

netstat -n 5

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.

2] Use netstat parameters to filter connection information

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.

  • Display active and inactive connections

Show the networks that are active or inactive.

netstat -a
  • Display applications information

List all applications that are associated with the connections.

netstat -b
  • View network adapter stats

Show statistics on incoming and outgoing network packets.

netstat -e
  • Display foreign addresses’ fully qualified domain name (FQDNS)

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.

netstat -f
  • Show port numbers instead of names

Change the foreign address port names to port numbers.

netstat -n

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

netstat -o
  • Filter connections by protocol

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

netstat -p udp

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

  • View non-listening and listing port

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

netstat -q

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

netstat -s

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.

netstat -r
  • Display offload state connections

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

netstat -t
  • See NetworkDirect connections

Shows all NetworkDirect connections.

netstat -x
  • Display connection Templates

Show your networks’ TCP connection templates.

netstat -y

3] Combining Netstat parameters

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:

netstat -s -e

You can write it as:

netstat - se

netstat se command

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.

Can we check network connectivity using netstat?

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.

How do I see network issues in Windows?

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. Once you’re in the Settings menu, select “Network & internet.” The status of your network connection will be displayed at the top of the page. If you’re having trouble connecting to the internet, this is a helpful first step in troubleshooting the issue. You also check quickly, and if you see the wifi icon missing, you have a network issue.

Google Pixel 8 and Pixel 8 Pro problems and how to fix them

Google continues to refine what it started with the Pixel 6 series, with the Pixel 8 and Pixel 8 Pro offering the perfect mix of expected updates and a slew of useful new features. The cameras, in particular, come with newer hardware and a variety of AI-powered software features that take your smartphone photography to the next level. The latest Pixels address a lot of the pain points from previous generations but, unfortunately, have their fair share of bugs and issues as well. Here’s a look at some common Pixel 8 and Pixel 8 Pro problems and how to fix them.

Editor's note: It's important to remember that not every Pixel 8 and Pixel 8 Pro will have these problems. In fact, you might not come across any issues at all.

Problem #1: Random reboots and app crashes

Rita El Khoury / Android Authority

Many Pixel 8 and Pixel 8 Pro owners complain about problems with their phones randomly restarting or apps freezing and crashing.

Potential solutions:

  • Clearing the app cache should help fix problems with apps crashing or freezing. Go to Settings > Apps > See All Apps > (app name) > Storage and Cache, and tap Clear cache. You can also tap Clear Storage if clearing the cache doesn’t work. However, this will reset the app, and you will lose any stored app data.
  • You might also notice app problems and random reboots because of issues during the setup process if you transfer your apps and phone data from an older phone. It’s time-consuming, but it might be best to factory reset the phone and set it up like a new device.
  • A rogue app is likely causing random reboots. Boot the phone into Safe Mode (the instructions are in the Guides section below) and see if the problem persists. If there’s no problem when using Safe Mode, exit this mode and uninstall any recently installed or updated apps to see if the issue goes away.
  • The first update for the Pixel 8 series is rolling out now. The November update brings plenty of bug fixes and might help fix this issue too. The rollout might take some time, but you can check if the update is available by going to Settings > System > System Update and tapping Check For Update.

Problem #2: Rapid battery drain

Ryan Haines / Android Authority

In Android Authority’s Pixel 8 and 8 Pro battery tests, we found that the battery life was better compared to its predecessors, with both phones able to comfortably last a full day. However, plenty of users report issues with rapid battery drain. Some say that the phone loses as much as 30 percent of battery life in just an hour.

Potential solutions:

  • From the ambient temperature to the chipset, lots of factors determine a phone’s battery life. And it’s normal to find faster-than-usual battery drain for a few days after you set up your new phone. This is the time when the phone is learning your usage habits to make the most of the Pixel’s Adaptive Battery feature. However, continued instances of significant battery drain after a week or so point to other problems. Check out our guide on what to do if your phone suffers from rapid battery drain or poor battery life for some useful tips and tricks.
  • You can check if a particular app or hardware is causing this battery drain. Go to Settings > Battery > Battery Usage. You can sort by View By Apps to see the screen time and background battery usage of your apps. Open the dropdown and select View By Systems to check if hardware like the CPU, Screen, mobile or Wi-Fi network connectivity, or the camera is causing problems.
  • Change the app battery usage setting to see if that makes a difference. Tap the app in the Battery Usage page mentioned above and select Optimized or Restricted. If the app isn’t among your recently used apps, go to Settings > Apps > See All Apps > (app name) > App battery usageOptimized is the better option here since Restricted might cause other app issues like delayed notifications.

Problem #3: Overheating

Ryan Haines / Android Authority

Complaints about the Pixel 8 and 8 Pro overheating are quite common, with users saying the phones get uncomfortably warm even with light usage, like scrolling through a web page. Overheating will cause issues like throttled performance and rapid battery drain.

Potential solutions:

  • Remember that it’s normal for the phone to overheat slightly when setting it up, playing processor-intensive games, or with long camera use. But if it happens with everyday use, there are a few things you can try to stop your phone from overheating (some steps are specific to Samsung phones, but the general settings apply to the Pixel 8 devices). Stop using your phone if it’s overheating, and turn it off to let it cool down.
  • Google’s monthly updates and frequent app updates might cause overheating issues too. The company tends to roll out fixes pretty quickly, but your only option is to wait for a software update.
  • If a rogue app is causing the issue (you can test it by running the app in Safe Mode), the best option is to uninstall any recently installed or updated apps to see if the problem goes away.
  • Some users say that they had no choice but to get a replacement device. You might have to do so as well if it’s a hardware problem.

Problem #4: Lag and stuttering

Ryan Haines / Android Authority

The Pixel 8 and 8 Pro’s Tensor G3 processor may not be as powerful as some of the competition, but you can still expect flagship performance from these phones. However, some users complain about lag and stuttering when scrolling through apps and web pages.

Potential solutions:

  • The Pixel 8 Pro comes with a variable 120Hz refresh rate, and frequent changes might cause some stutter.
    • You can try switching to a lower refresh rate. While everything may not be as smooth, it should be more consistent. Go to Settings > Display and toggle off Smooth Display.
    • You can also force the phone to always stay at the highest refresh rate. You’ll need to first enable Developer Options. Go to Settings > About Phone, scroll down to Build number, and tap it multiple times until you see a pop-up that says, “You are now a developer.” Then go to Settings > System > Developer Options and search for and toggle on Force Peak Refresh Rate.
  • For stutter while scrolling, you can try reducing the touch feedback sensitivity. Go to Settings > Sound and Vibration > Vibration and Haptics and reduce the touch feedback.
  • Some users say that disabling Graphics Driver Preferences also helps with performance issues. After enabling Developer Mode, go to Settings > System > Developer Options and toggle off Graphics Driver Preferences.

Problem #5: Android Auto issues

Android Auto problems aren’t as common as was the case with previous generations, but a few users still face problems using the feature properly. Some say that the phone doesn’t connect or frequently disconnects, or they see a blank screen on the car display.

Potential solutions:

  • Android Auto problems tend to occur because of issues with transferred settings from an older phone. Go to Settings > Apps > Android Auto > Storage and Cache and clear both to reset Android Auto.
  • A faulty cable might be the problem. Test the cable with other phones and ensure it isn’t torn or frayed. You’ll need to get a new cable to fix the issue.
  • Check out our guide on common Android Auto problems and how to fix them for solutions for issues like a blurry, pixelated, or blank screen, Android Auto Wireless problems, and more.

Problem #6: Wi-Fi and mobile network connectivity issues

Ryan Haines / Android Authority

Potential solutions:

  • For issues with the Wi-Fi slowing down when switching access points on a home mesh network, a user says that changing a phone setting seems to do the trick. Go to Settings > Network and Internet > Internet and click on the gear icon next to the Wi-Fi name to go into Network Details. Tap Privacy and switch the option to Use device MAC. Remember to use this setting just for your trusted home network, and keep the setting to Randomized MAC for everything else.
  • Some users say that switching to an eSIM from a physical SIM card seems to help with network connectivity and data speeds. If you already have an eSIM set up, contact the network carrier to reprovision the SIM. And for physical SIM cards, you might need to get a new one. Users on T-Mobile say that a new physical SIM card solves the issue.
  • You can also try setting the phone to LTE-only for a more stable connection, even if the data transfer speeds are slower. This setting also helps with the problem of phone calls not coming through properly. On the other hand, some users say that setting it to 5G-only helps. It all depends on how good the network coverage is in your area.
    • Go to Settings > Network and Internet > Internet and tap on the gear icon next to your network carrier’s name. Scroll down to Preferred Network Type and select LTE or 5G.
    • If you don’t see that option (some network carriers may block it), dial *#*#4636#*#* and tap Phone Information. Go to Set Preferred Network Type, and from the dropdown, select NR (for 5G).
  • For problems with call connectivity, apart from setting the network to LTE or 5G only, users say that turning off Wi-Fi Calling and Adaptive Connectivity also helps.
    • Go to Settings > Network and Internet > Adaptive Connectivity and toggle it off.
    • Go to Settings > Network and Internet > Internet, tap on the gear icon next to your network carrier’s name, and toggle off Wi-Fi Calling.

Problem #7: Camera and Google Photos problems

Ryan Haines / Android Authority

Multiple users have reported problems with the camera app on the Pixel 8 and Pixel 8 Pro crashing just after launch and issues with focus. Others say that the Google Photos app doesn’t appear to sync properly and doesn’t play recorded videos.

Potential solutions:

  • The phone’s auto-rotate function seems to be causing problems with the camera app crashing. It’s also been causing issues with Google Maps and other apps. Tap on Auto-rotate in the Quick Settings dropdown (swipe down twice from the top) to disable it.
  • You can also try clearing the app cache. Go to Settings > Apps > See All Apps and search for Camera and Pixel Camera Services. With both, tap Storage and Cache and select Clear Cache. You can do the same to fix issues with Google Photos as well.
  • Some users say that the Repainter app seems to break auto-rotate and cause the Camera app and Google Maps to crash. Uninstalling the app fixes the problem.
  • Problems with focus might be because of hardware, so you’re only option is to send the phone for repair or pick up a replacement.

Problem #8: Error when trying to use Wi-Fi Hotspot

Ryan Haines / Android Authority

A few users are facing problems using Wi-Fi Hotspots with their phones. When they try to toggle on the feature, it shows an error and doesn’t activate.

Potential solutions:

  • First, ensure that your network carrier allows Hotspot connectivity. Some carriers charge an additional fee to use this feature.
  • The best option is to wait for a software update, but there is a tedious workaround available that you can use in a pinch. When you plan to use Hotspot, switch the phone to Airplane Mode (tap on the setting in the Quick Settings dropdown). Restart the phone, enable Wi-Fi Hotspot (if you don’t have it in your Quick Settings menu, go to Settings > Network and Internet > Hotspot and Tethering and toggle it on), and then turn off Airplane Mode.

Problems where the only option is to wait for a software update

Adamya Sharma / Android Authority

There are a few Pixel 8 and Pixel 8 Pro problems that don’t have workarounds. However, these are mostly software bugs that will likely be fixed with a future software update. Your best is to contact Google support and report the issue.

  • Touchscreen unresponsive when wirelessly charging the phone: Some users say that the phone screen doesn’t respond to any touch inputs when placed on the Pixel Stand or Pixel Stand 2nd Gen. However, the problem seems to be limited to Google’s wireless chargers, with users reporting no issues when using third-party chargers.
  • Face verification failing on banking and other apps: Some apps, like banking apps, often require a picture of your face for verification. Users say that the verification process fails because the Pixel 8 series isn’t considered a supported device. The only option here is to wait for an app update.
  • No audio when recording video: Some users say that they only hear static or a buzzing sound when playing back a recorded video. You can try removing the phone case and ensure that there isn’t anything blocking the mic. However, this seems to be a software issue.

Guides: How to factory reset, how to boot into Safe Mode

How to boot into Safe Mode

  • If the phone is on, press and hold the power button and long-press the power off icon. A pop-up message will give you the option to reboot the phone into Safe Mode.
  • If the phone is off, press and hold the power button to start the phone. As soon as the animation starts, press the volume key and hold it until the animation ends. The phone should then boot into Safe Mode.
  • To exit Safe Mode, press the power button and select Restart.

How to Factory Reset the Pixel 8

When the phone is on

  • Go to Settings > System > Advanced > Reset options.
  • Select Erase all data (factory reset) and tap Reset phone.
  • Enter your PIN or pattern to confirm, and tap Erase Everything.

When the phone is off or unresponsive

  • Press and hold the power and volume down keys at the same time until Fastboot mode (triangle with an exclamation point) appears.
  • If No command appears, press and hold the power button. While still holding it, press the volume up button once and release both.
  • Go to Recovery mode using the volume keys for navigation and tap the power button to select.
  • Using the volume keys, go to Wipe data/factory reset and select Reboot system now once the phone is reset.

ATEC hosts multi-domain operations test demonstration

ABERDEEN PROVING GROUND, Md. — The U.S. Army Test and Evaluation Command executed its first Multi-Domain Operations Distributed Live, Virtual, Constructive Initial Operational Capability Demonstration across ATEC’s geographically diverse sites on Oct. 19.

This demonstration was the culmination of an ATEC enterprise modernization project, comprised of eight ATEC subordinate organizations on a distributed network, to establish an MDO scale distributed LVC test environment.

“The key focus of this event was to tie the ATEC subordinate organizations across the country on a distributed test network,” said Dr. Ken LeSueur, lead technical coordinator of the event supporting the U.S. Army Redstone Test Center. “We wanted to exercise a mixture of live, virtual and constructive elements operating on an MDO scale test scenario across that environment, collect data in that environment and push toward real-time visualization and analysis of that data.”

The event executed seven MDO land, air, space and cyberspace scenarios, that consisted of more than 60 live military systems, virtual assets and constructive simulations. Transformative data collection, real-time display and cloud-based data analytics on the representative tactical and simulated systems were executed in the event.

Mason Rowe, who served as the data collection, reduction, analysis and visualization lead for the event with the U.S. Army Evaluation Center, provided insight on the importance of near real-time analytics. “The significance of what we demonstrated today with our near real-time data analytics is proving that by embedding analysts and evaluators into the test itself, we can provide in-stride, data-driven insights using data dashboards and visualizations throughout test execution. Rather than waiting weeks after a test to have analysis ready datasets on-hand, we were able to shorten the data collection-reduction-analysis timeline to less than 60 seconds using automated, cloud-based processes.”

“This is beneficial for everyone,” said Rowe. “The testers will know what’s going on during the test allowing gaps to be identified so they can be immediately addressed rather than needing to schedule a follow-on test. The system owners will know what’s going on with their system allowing deep dives into the data to troubleshoot any errors or problems that can be fixed on the spot. And leadership will be provided the up-to-date insights and the health status of how a test is running through ongoing assessment of the data that was collected … ‘Is it the right data, does it answer your learning demands that you have for this test and is it going to be worthy for use in evaluation after the fact.’”

Paul Weimer, division chief for the cyber and electromagnetic affects division with ATC, explained that given where the Army is headed with MDO, the only way to get there is by learning how systems interoperate at scale, and that capability was highlighted in this demonstration. “This occurred in an environment where you’ve got live systems interacting with virtual systems cooperatively at scale. Innovative networks, constructive simulations and a talented workforce made that possible. If you embrace and invest in modeling and simulation early in the acquisition process, it will pay dividends throughout the life cycle of a system.”

“This exercise brought a lot of firsts for ATEC. Even though the concept of doing distributed testing isn’t new, it really hasn’t been done at the scale and complexity that we touched on today. This is a significant step in the right direction, but we are not at the end goal. We were able show the test and evaluation community what is in the realm of possible, but this effort also helped us identify our strengths, weaknesses, and gaps so we can take the right steps to achieve full operational capability to support the Army experimentation and testing.”

Although all the ATEC subordinate organizations were involved in the demonstration, ATC and RTC were the backbone behind this effort. According to LeSueur, RTC has had an extensive history of LVC distributed testing and ATC has the chamber, resources and infrastructure. “Each organization was essential in bringing this together. I think we moved all ATEC up a significant notch being able to perform this type of testing and methodology. We accomplished a lot of training across the command doing this.”

The Test Resource Management Center's Joint Mission Environment Test Capability Multiple Independent Levels of Security Network served as the foundation for the demonstration. It was managed and supported by TRMC’s National Cyber Range Complex, and the network was tailored for this event. “From project initiation through execution, TRMC’s NCRC project planners and network designers worked closely with ATEC to establish new network nodes at several ATEC sites as well as configure, test and tune the network for the application,” said Weimer.

James Amato, ATEC’s executive technical director/deputy to the commander, stated that leveraging TRMC’s capabilities will enable us to link our capability with other services and allies so we can literally test like we fight, as a joint and combined force.

ATEC Commanding General, Maj. Gen. James J. Gallivan, concluded the demonstration by stating, “this capability gives the Army an environment to support distributed user involved developmental and operational system-of-systems experimentation and testing at scale.”

The MDO Distributed LVC IOC falls under the digital transformation line of effort within the ATEC Next Campaign Plan, with an end goal to have systems and processes in place to perpetually modernize the people, equipment and infrastructure to remain trusted by senior leaders for decisions.

Brian Kelly, ATEC’s chief data officer, said that ATEC is leading test and evaluation for the Army through an enterprise-wide digital transformation that leverages a hybrid cloud environment to develop a data mesh. The ATEC data mesh leverages various Army enterprise cloud services to expose and control access to data for DoD and its partners. “ATEC’s digital transformation is well underway and will serve as a shining example of an Army Business Mission Area organization meeting the intent of HQDA CIO and G6 data and cloud strategies.”


The U.S. Army Test and Evaluation Command provides direct support to Army Futures Command and relevant, timely information to senior Army leaders to make future force decisions enabling Multi-Domain Operations through rigorous developmental testing and independent operational tests and evaluations.

Those who tested positive for COVID-19 (confirmed by a PCR test) had an increased risk of mental illness, fatigue and sleep problems, finds a new study which analysed the electronic primary care health care records* of 226,521 people from across the UK between February 2020 and December 2020.

The research**, published in The Journal of the American Medical Association Network Open (JAMA Network Open) today, was funded by the National Institute for Health Research Greater Manchester Patient Safety Translational Research Centre (NIHR GM PSTRC). The Centre is a partnership between The University of Manchester and The Northern Care Alliance NHS Foundation Trust.

The study found there was an almost six-fold increase in the likelihood of reporting fatigue to a GP following a positive PCR test and a threefold increase in the risk of sleep problems compared to those without a positive test, for people who haven’t previously visited their GP for any of these reasons in the past.

There was also an 83% increase in mental illness following a positive PCR test. However, there was also a 71% increase in the risk of mental illness for people who received a negative PCR test compared to the general population. Researchers believe this throws some doubt about whether COVID-19 is directly causing mental illness, because it is clear that those who get a test are more likely to have risk factors for mental illness, for example pandemic-related anxieties.

Dr Matthias Pierce, researcher at The University of Manchester who led the work, said: “When we began this research project we wanted to investigate whether we could find any evidence in primary health care records that COVID-19 was linked to an increased risk of mental health illness, sleep and fatigue problems.

“While fatigue is clearly a consequence of COVID-19 the risk of experiencing sleep problems is also very high. However, we are sceptical regarding the extent that COVID-19 is directly causing people to become mentally ill, or whether those with a predisposition to mental illness are more likely to get tested.”

Professor Roger Webb, from The University of Manchester, who co-leads the Mental Health research programme at the NIHR GM PSTRC, said: “Our findings align with those generated by investigations conducted in other countries in revealing elevated risks of mental illness, self-harm, fatigue, and disrupted sleep patterns among people testing positive for infection during the pandemic. Establishing the mechanisms that have caused these outcomes to occur is the next major challenge for researchers in our field.”

Professor Carolyn Chew-Graham, a co-author on the paper, Professor of General Practice Research at Keele University and a General Practitioner, said “It is vital that general practitioners recognise the long-term impact of COVID-19 infection on their patient population. Offering follow-up to people who test positive for COVID-19 infection may help identify persisting symptoms, and sign-post people to the Your COVID Recovery website. The increased risk of developing mental health problems in people who tested negative may be due to health anxiety in these patients, and primary care has a role in identifying and supporting such patients.”
