Fix: Ethernet-port fungerer ikke på Windows 7/8/10

Selvom de fleste af os bruger Wi-Fi i disse dage, er der tidspunkter, hvor du vil bruge Ethernet til internetforbindelse. Husk, at definitionen af ​​Ethernet er meget forskellig fra, hvad vi normalt bruger ordet "Ethernet" til. Det kaldes normalt den kabelforbindelse med internetrouteren. Du har muligvis set ledninger, der går fra bagsiden af ​​computere til internetroutere. Generelt, når nogen siger, at deres Ethernet ikke fungerer, hvad de mener er, at deres computer har problemer med at oprette forbindelse til internettet. Og da deres computer er forbundet til internettet via et kabel, har kablet eller dets driver eller netværkskortet noget problem.

Spørgsmålet om, at Ethernet ikke fungerer, kan være relateret til mange ting. Da vi ikke taler om en bestemt fejlmeddelelse, er der masser af ting, der kan forårsage dette problem. Det kan være en problematisk ledning, løs forbindelse, netværkskort, forældet driver og andet. Problemet kan skyldes både et hardwareproblem og et softwareproblem. Så vi bliver nødt til at gennemgå flere metoder, der dækker både software- og hardwareproblemer, der kan forårsage Ethernet-problemer.

Tips

• Nogle gange kan problemet simpelthen være en ødelagt havn. Så sørg for at du bruger den rigtige port på routeren. Der er flere porte på en router, og du skal slutte dit Ethernet-kabel til en anden. Når du er færdig, skal du kontrollere, om problemet er løst.
• Midlertidig deaktivering af dit antivirus er en anden ting, der kan forårsage problemet. Næsten alle antivirusprogrammer har en deaktiveringsmulighed. Deaktiver dit antivirusprogram i et par minutter, og kontroller, om Ethernet fungerer eller ej.

Metode 1: Kontroller, om Ethernet er aktiveret

Nogle gange kan problemet skyldes et deaktiveret Ethernet. Ethernet og forskellige andre enheder kan let deaktiveres fra Enhedshåndtering. Selvom du ikke kan huske at deaktivere Ethernet, er det god praksis at kontrollere status. Nogle gange er enheder deaktiveret tilfældigt eller på grund af en fejl.

Følg disse trin for at kontrollere og aktivere dit Ethernet

1. Hold Windows-tasten nede, og tryk på R
2. Skriv devmgmt.msc og tryk på Enter

3. Dobbeltklik på netværkskort
4. Find og højreklik på din netværksenhed
5. Vælg Aktiver . Hvis du ser en Deaktiver- indstilling, betyder det, at din enhed allerede er aktiveret. I dette tilfælde skal du klikke på Deaktiver og derefter vælge Aktiver Dette genstarter enheden.

Når det er gjort, skal du kontrollere, om Ethernet fungerer eller ikke.

Metode 2: Aflæs strøm

Dette er et gammelt trick, men det har fungeret for mange brugere. Aflæsning af strøm fra din pc løser problemet. Følg instruktionerne nedenfor for at udføre denne metode

1. Sluk for dit system
2. Tag / tag netledningen ud. Fjern batteriet, hvis du har en bærbar computer
3. Hold tænd / sluk-knappen nede i 30 sekunder, og slip den derefter
4. Tilslut nu systemet (eller isæt batteriet, hvis du har en bærbar computer)
5. Tænd dit system

Dette skal løse problemet. Alt skal være i orden nu.

Metode 3: Opdater drivere

Hvis ovenstående to metoder ikke fungerede, er chancerne for, at du har en defekt driver. Der er et par ting, du kan gøre med dine chauffører. For det første skal du prøve at rulle driverne tilbage, hvis problemet opstod efter en driveropdatering. De nyeste drivere har undertiden et problem med fejl eller kompatibilitet. Dernæst skal du opdatere driverne til den nyeste version. Du kan gøre det både automatisk og manuelt. Endelig skal du afinstallere og lade Windows installere en generisk driverversion til dit netværkskort.

Bemærk: Da du har problemer med at oprette forbindelse til internettet, fungerer nogle af disse trin muligvis ikke for dig. For eksempel kan du ikke søge i den nyeste driver på internettet og downloade den. Du skal gøre det fra en anden pc, ideelt set fra den, du læser denne artikel, og kopiere den til dit system med problemet.

Hvis du for nylig har installeret en opdateret driver

Selvom det er usandsynligt, at en opdateret driver vil forårsage dette problem, men det er ikke helt umuligt. Hvis du for nylig har installeret en ny version, er der en god chance for, at rullende tilbage til den tidligere version muligvis løser problemet.

1. Hold Windows-tasten nede, og tryk på R
2. Skriv devmgmt . msc, og tryk på Enter

3. Dobbeltklik på netværkskort
4. Find og dobbeltklik på din netværksenhed
5. Klik på Driver- fanen
6. Klik på Rul tilbage driver ... og følg instruktionerne på skærmen. Bemærk: Hvis knappen "Rul tilbage driver ..." er nedtonet, betyder det, at du ikke kan gå tilbage til den forrige version.

Hvis du vender tilbage til den tidligere version, skal du genstarte computeren, når processen er færdig, og kontrollere, om problemet er løst eller ej. Hvis problemet stadig opstår, skal du prøve at opdatere driveren.

Opdatering

Bemærk: Du kan muligvis ikke følge alle trin, fordi disse trin kræver internetadgang. Så følg disse trin på en anden pc, og overfør den downloadede fil via USB.

Du kan opdatere driveren automatisk såvel som manuelt. Den automatiske opdatering fungerer dog ikke for dig, fordi din Windows søger efter driveren, og det kræver internetadgang. Den manuelle opdatering kræver også internettet, men du kan downloade driveren fra en anden pc og overføre den til offerets computer.

Manuel opdatering:

1. Hold Windows-tasten nede, og tryk på R
2. Skriv devmgmt.msc og tryk på Enter

3. Dobbeltklik på netværkskort
4. Før du opdaterer din driver, skal du kontrollere, om du har den seneste driverversion eller ej. Følg trinene nedenfor for at gøre dette
   1. Find og dobbeltklik på din netværksenhed
   2. Klik på Driver- fanen
   3. Se i førersektionen . Du vil se driverversionen. Bemærk driverversionen, eller hold dette vindue åbent

   

   4. Gå nu til din driverproducentens websted og søg efter den nyeste driver på din enhed
   5. Kontroller, om du har den nyeste version eller ej. Hvis du har den nyeste version, skal du springe til afsnittet Afinstaller nedenfor. Ellers skal du downloade driveren og fortsætte

5. Find og højreklik på din netværksenhed
6. Vælg Opdater driver software ...

7. Klik på Gennemse min computer for driver-software

8. Klik på Gennemse, og vælg den driver, du downloadede før (i vores tilfælde til det sted, hvor du kopierede den downloadede driver)
9. Klik på Næste, og følg eventuelle yderligere instruktioner på skærmen

Når du er færdig, skal du genstarte din computer og kontrollere, om problemet er løst.

Afinstaller

Installation af din driver er vejen at gå, hvis opdatering ikke fungerede. Når du afinstallerer en driver, installerer Windows automatisk en generisk driver til din enhed, næste gang du starter din maskine. Disse generiske drivere er ikke de nyeste, men de er de mest kompatible versioner. Så dette fungerer muligvis for dig.

1. Hold Windows-tasten nede, og tryk på R
2. Skriv devmgmt.msc og tryk på Enter

3. Dobbeltklik på netværkskort
4. Find og dobbeltklik på din netværksenhed
5. Højreklik på din displayenhed, og vælg Følg eventuelle yderligere instruktioner på skærmen

6. Vent til det afinstalleres

Genstart computeren, når afinstallationsprocessen er afsluttet. Ved genstart skal de generiske drivere installeres. Dette skulle løse problemet, hvis det skyldtes et driverproblem.

Metode 4: Kontroller netværkskablet

Når Ethernet-forbindelsen er aktiveret, i vinduet Netværksforbindelser , kan du også kontrollere dens status. Denne proces er meget vigtig for at identificere årsagen til problemet. For eksempel, hvis din computer ikke genkender kablet fra starten, ville der naturligvis ikke være nogen forbindelse oprettet. Denne uigenkendelse kan skyldes en række årsager. Følg nedenstående trin for at kontrollere netværkskablet.

1. Tryk på "Windows" + "I" for at åbne indstillingerne.
2. I Windows-indstillinger skal du klikke på "Netværk og internet" og derefter klikke på "Ethernet" fra venstre side.
3. Nu viser den et antal Ethernet-forbindelser i det næste vindue, eller det viser måske kun den ene.
4. Hvis der står "Ikke tilsluttet" under Ethernet-forbindelsen, betyder det, at kablet ikke genkendes fra farten, og der er enten et problem med adapteren, kablet eller softwaren, der skal genkende det.

Hvis dit kabel ser ud til at være tilsluttet, skal du prøve at afbryde det og tilslutte det igen. Kabler kan forringes med tiden eller fra forkert håndtering. Hvis din Ethernet-adapter stadig viser netværkskablet som frakoblet, kan du prøve at skifte til et andet kabel. Du kan også prøve en anden port på routeren, switch eller modem (hvis der er flere tilgængelige), da nogle gange kan disse porte ikke fungere.

Metode 5: Overvåg dine forbindelsesoplysninger

I nogle tilfælde er det fuldt ud muligt, at ethernet ikke genkendes korrekt af computeren, fordi du eller din computer måske har forkert konfigureret nogle af de netværksoplysninger, der kræves for at forbindelsen skal oprettes korrekt. Derfor overvåger vi i dette trin nogle forbindelsesoplysninger og kontrollerer, om vi korrekt har identificeret alle parametre. For det:

1. Tryk på "Windows" + "R" for at åbne kør-prompten.
2. Indtast "ncpa.cpl" og tryk på "Enter" for at starte netværkskonfigurationspanelet.
3. Inde i netværkskonfigurationen skal du højreklikke på "Ethernet" -adapteren, som din computer bruger.
4. Vælg indstillingen "Egenskaber" i menuen for at åbne Ethernet-egenskaberne.
5. Inde i vinduet "Ethernet Properties" skal du dobbeltklikke på "Internet Protocol Version 4 (TCP / IPV4)" og dette skulle åbne IPV4-konfigurationsvinduet.
6. I dette vindue skal du sikre dig, at du har markeret "Få en IP-adresse automatisk" og "Hent DNS-server automatisk" .
7. Selvom der er scenarier, hvor disse detaljer skal indtastes manuelt, men vi skal først sørge for, at computeren er i stand til korrekt at få disse oplysninger automatisk.
8. Efter at have gjort denne informationsudtrækning automatisk, skal du kontrollere, om problemet stadig vedvarer.

BEMÆRK: Mens de fleste forbindelser bruger IPv4, kan du i vinduet Ethernet-egenskaber også finde en indstilling kaldet Internet Protocol Version 6 (TCP / IPv6) . Hvis dit netværk bruger IPv6, bliver du nødt til at foretage ændringerne her og ikke i IPv4-indstillingen som beskrevet ovenfor.

Metode 6: Sluk for antivirusbeskyttelse

I nogle tilfælde er det fuldt ud muligt, at en Windows-komponent faktisk kan være roden til dette problem på din computer. Windows Firewall eller Windows Defender forårsager muligvis dette problem på din computer. Derfor deaktiverer vi i dette trin både Windows Defender og Windows Firewall for at sikre, at de ikke er synderen. Det er også muligt, at tredjeparts antivirusbeskyttelse forårsager dette problem, så sørg også for at deaktivere enhver tredjepartsbeskyttelse. For at fortsætte:

1. Tryk på "Windows" + "R" for at åbne kør-prompten.
2. Indtast "Kontrolpanel" og tryk på "Enter" for at starte den klassiske Kontrolpanel-grænseflade.
3. In the Control Panel, click on the “ViewBy:” option and select the “Large Icons” button.
4. After making this selection, click on the “Windows Defender Firewall” option to launch the Firewall and then select the “Turn Windows Defender Firewall On or Off”.Opening Windows Defender Firewall from Control Panel
5. Make sure to uncheck the “Turn On Windows Defender Firewall” for both the available options to turn the Firewall Off.
6. After making this selection, save your changes and close out of the Window.
7. Press “Windows” + “I” to open the windows Settings.
8. Inside the settings, click on the “Update and Security” option and select the “Windows Security” button from the left side.
9. On the next screen, click on the “Virus and Threat Protection” option and click on the “Manage Settings” option below the “Virus and Threat protection settings” heading.
10. After clicking on this option, turn the toggle off for “Realtime Protection”, “Cloud-Delivered Protection”, “Automatic Sample Submission” and “Tamper Protection”.
11. After disabling all of these, navigate back to the desktop and check to see if the issue still persists.

Method 7: Reset Network Settings

Sometimes, the issue might be caused by some network reconfigurations that we have been unable to fix until now. This might be because these are some root system configurations or cache that have been corrupted and the only way to fix it is by performing a complete overhaul of the network settings. In order to do so, follow the guide below.

1. Press “Windows” + “R” to open the Run prompt.
2. Type in “Control panel” and press “Enter” to launch the classical control panel interface.
3. Inside the Control Panel, click on the “View By:” option and select the “Large Icons” from the list of available options.
4. After selecting the Large Icons, click on the “Network and Sharing Centre” option.
5. In the Network and Sharing Centre, select the “Internet Options” option and from the left navigation pane at the bottom.
6. In the new window that opens up, click on the “Advanced” tab, and then select the “Restore Advanced Settings” option to reset the advanced network settings.
7. After this, press “Windows’ + “I” to open the Windows Settings.
8. In the settings, click on the “Network and Internet” option and select the “Status” button on the left side of the next screen.
9. Scroll down on the next screen until you reach the “Network Reset” option.
10. Click on the “Network Reset” option to prompt the computer to initiate the reset request and select the “Reset Now” button on the next screen.
11. Confirm any prompts that ask you if you really want to initiate a network reset and prepare to restart your computer.
12. The automatic prompt should wait for some time before initiating a restart so you should have some time to back up or save any work that you have unsaved.
13. When the computer restarts, you’ll notice that your network connection isn’t active. This is because your network card is firstly reset and then released its previous connection. Just select the network icon, pick the network you want to reconnect to, and choose “Connect”.
14. If your TCP/IP settings are set to automatically detect, your network connection should detect the appropriate network settings and connect to the ethernet without any problems.
15. Check to see if the issue still persists.

Method 8: Enable Ethernet Adapter Through BIOS

Some motherboard manufacturers might disable the ethernet connection from the Bios in the factory default settings or in some cases while tinkering around with the Bios, you might have disabled this setting yourself. Therefore, in this step, we will be enabling the Ethernet Adapter from the Bios. For that:

1. Make sure to completely shut down your computer and turn it back on after a while.
2. While the computer is being started, pay close attention to the “Press “X” button to get into the Bios” message that might appear during the startup.
3. Press the indicated key quickly and repeatedly to enter your computer’s BIOS. Once in the BIOS, you can use the arrow keys on your keyboard to navigate through the available options.
4. Find “Integrated Peripherals,” “Onboard Devices,” “On-Chip PCI Devices,” or a similar option and press the “Enter” key to access the menu. Depending on the type and year of your BIOS, the exact menu text will vary.

   Note: Generally, you should find something that indicates the settings are related to your onboard integrated peripherals.

5. Find and select “Integrated LAN,” “Onboard Ethernet,” or a similar option and use the left and right arrow keys to cycle through the available options. In most cases, these are either “Enabled” or “Disabled.”
6. Press the “F10” keyboard key, this should display a dialog asking if you would like to save your settings and exit the BIOS. Press the “Y” keyboard button to confirm. This causes the computer to reboot. Windows should now automatically detect and use your Ethernet controller.
7. Check to see if the issue still persists.

Method 9: Run the Internet Connection Troubleshooter

If due to some issue, you are still unable to get your ethernet connection functioning properly, a great option to try with Windows 10 is to run the internet troubleshooter. Not only does it provide you the reason due to which the ethernet isn’t working, but it might also attempt to fix the issue. In order to run the troubleshooter, follow the guide below.

1. Press “Windows” + “I” on your keyboard to launch the settings.
2. In the Settings, navigate to “Update & Security” option and afterward choose “Troubleshoot”.
3. Click on the “Network Connections” option and then select the “Run the troubleshooter” option to successfully run this troubleshooter on your computer.
4. Follow the on-screen instructions to completely run this troubleshooter and then check to see if the issue still persists.

Method 10: Ping the Loopback Address

A loopback address is a special IP address, 127.0. 0.1, reserved by InterNIC for use in testing network cards. This IP address corresponds to the software loopback interface of the network card, which does not have hardware associated with it, and does not require a physical connection to a network. Some users have highlighted that this issue may arise due to system corruption or malware installed that prevents networking from functioning properly, hence perform the ping operation to verify whether your network card is working properly or not:

1. Press “Windows” + “R” to open the Run prompt.
2. Inside the Run prompt, type in “cmd” and then press “Shift’ + “Ctrl” + “Enter” to provide administrative privileges.
3. Type the command, ping 127.0.0.1. This will send a message to the internal network stack on the machine. A response similar to the following should occur:

   Pinging 127.0.0.1 with 32 bytes of data: Reply from 127.0.0.1: bytes=32 time<10ms TTL=128 Reply from 127.0.0.1: bytes=32 time<10ms TTL=128 Reply from 127.0.0.1: bytes=32 time<10ms TTL=128 Reply from 127.0.0.1: bytes=32 time<10ms TTL=128 Ping statistics for 127.0.0.1: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milliseconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms

4. If the command prompt is successful in pinging the IP Address, it means that networking should be working on your computer and the issue most probably lies within a software misconfiguration and you may continue to implement these fixes on your computer.

Method 11: Verify Router’s Firmware

There are often new firmware updates to a router/Access Point that may resolve some issues. These are especially for the equipment more than a few years old that is running the original firmware. Consult the equipment manufacturer’s product documentation or website for details and instructions on how to perform an update.

Often, vendors of the router/Access Points will add features to improve their product. Unfortunately, these extra features are not always compatible with all wired hardware. Consult the product documentation or manufacturer’s website for the router/Access Point about the possible need to disable these features.

Method 12: Reset Network Stack

If you are still unable to fix this issue on your computer, it might mean that the computer has acquired it as a result of some corrupted DNS cache or due to invalid network cache. Therefore, in this step, we will be completely resetting the network stack which should get rid of this invalid cache and replace it with a newly generated one. In order to do that:

1. Press “Windows” + “R” to open the Run prompt.
2. Type in “Cmd” and then press “Shift” + “Ctrl” + “Enter” to provide admin permissions.
3. Inside the command prompt, type in the following commands and press “Enter” after each to execute it on your computer.

   ipconfig /release ipconfig /flushdns ipconfig /renew netsh int ip reset netsh winsock reset

4. After executing these commands on your computer, make sure to perform a complete restart to ensure that they are properly executed.
5. Check to see if the issue still persists.

Note: Please note that these commands affect all of your networking adapters, both physical and virtual, both used and unused, so you will see some errors when running these commands, where the resets targeted adapters that are not being used. These errors are perfectly normal, and not a cause for concern. Please complete each step, in order, even if you have done some of these previously, and even if you encounter errors.

Method 13: Disable Virtual Ethernet Devices

If you haven’t found a solution yet and are still receiving Ethernet port error then you should try to remove any virtual Ethernet drivers on your PC as these can cause major issues with how your PC connects to the internet. A virtual Ethernet driver could be anything from a VPN to software designed to improve ping or packet loss. You can find virtual Ethernet devices and disable them by following the steps below.

1. Press “Windows” + “R” to open the Run prompt.
2. In the Run prompt, type in “ncpa.cpl” and press “Enter” to open the network configuration panel.
3. In the network configuration, right-click on any entry that seems to belong to software and is not a physical connection that your computer is connected to.
4. Select the “Disable” option to disable the virtual network connection.
5. If you’re unsure, you can Google the name of each network device to learn more before disabling them.

Method 14: Disable Auto-Tuning Feature

The Window Auto–Tuning feature lets the operating system continually monitor routing conditions such as bandwidth, network delay, and application delay. Although it lets the operating system configure connections by scaling the TCP window to maximize the network performance it has proved to be the potential culprit in this case. Hence, temporarily disable the auto-tuning feature to get rid of the Ethernet port problem:

1. Press “Windows” + “R” to open the Run prompt.
2. Inside the Run prompt, Type in “cmd” and then press “Shift” + “Ctrl” + “Enter” to launch with administrative privileges.
3. Type in the following command inside the command prompt and press “Enter” to execute it.

   netsh interface tcp show global

5. Now, look for the Receive Window Auto-Tuning Level feature and if it’s normal, disable it.
6. In order to disable it, type in the following command and press “Enter” to execute it.

   netsh int tcp set global autotuninglevel=disabled

7. After the commands have been executed, check to see if the issue still exists.

Method 15: Tweak Duplex Settings

There are two types of duplex settings used for communications on an Ethernet network: Half-duplex and full-duplex. According to users, sometimes you might experience Ethernet problems due to your duplex settings. After changing your duplex settings not only the Ethernet port problem would be resolved but your LAN speed will also increase.

1. Press “Windows” + “R” to open the Run prompt.
2. Type in “ncpa.cpl” and press “Enter” to launch the network configuration panel.
3. Inside the network configuration panel, right-click on your ethernet connection and then select “Properties” to open the ethernet properties.
4. In the ethernet properties, navigate to the “Advanced” tab and select “Speed/duplex settings”.
5. Now set Value to “100 MB Full Duplex”. You can also try other 100MB values, or you can use “Auto Negotiation”
6. After doing that, click “OK” to save your changes.
7. Check to see if making this change has fixed our issue.

Method 16: Disable Large Send Offload (LSO)

Large Send Offload is one of the latest features in Windows 10. LSO is actually meant to improve the overall network performance of the system, but contrary to its purpose, this feature actually allows background applications to consume a considerably large amount of network bandwidth. Some users reported that they were able to get around this problem by disabling this feature on their Operating systems:

1. Press “Windows” + “R” to open the Run prompt, type in “Devmgmt.msc” in the run prompt and press “Enter” to launch the device manager.
2. Double click on the “Network Adapters” panel to expand it and right-click on the network adapter that your computer is using.
3. Select the “Properties” option to launch the network properties.
4. Inside the network adapter properties, click on the “Advanced” tab from the top.
5. Select “Large Send Offload V2 (IPv4)” and set the value to “Disabled”.
6. Do the same for “Large Send Offload V2 (IPv6)” and click “OK”.

Method 17: Resolve Issues With Your Network Adapter

There may be some underlying issues with your network adapter that can be quickly diagnosed within the Windows control panel. If you’ve already updated your network adapter drivers, follow the steps below to try and diagnose other issues.

1. Press “Windows” + “R” to open the Run prompt.
2. Type in “ncpa.cpl” and press “Enter” to launch the network configuration panel.
3. In the network configurations, right-click on the ethernet adapter and select the “Diagnose” option.
4. Let the automatic diagnosing begin and follow the on-screen instructions to fully diagnose issues with the ethernet connection.
5. Check to see if running the diagnose window fixes this issue.

By default, if your network adapter is set to use a static IP address but it should be using DHCP, this should fix it. However, it’s a good idea to check yourself too.

Method 18: Verify Whether Ethernet Port is configured for Dynamic IP

If your computer is unable to communicate with other networked devices or connect to the Internet via Ethernet, check your network settings to confirm that the Ethernet port is configured for a dynamic IP address.

1. Click on the start menu icon and select the “Settings’ option.
2. Click the “Network and Internet” button to open internet settings.
3. Afterward, choose the “Network and Sharing Center” option and from the window opened at front choose “Change Adapter Settings” in the window’s left menu.
4. Right-click the “Local Area Connection” icon in Windows 7 or the “Wired Ethernet Connection” icon in Windows 8/10 and select “Properties.”
5. Double-click “Internet Protocol Version 6 (TCP/IPv6)”
6. Confirm that the “Use the Following DNS Address” button is checked.

   Note: Get ahold of a PC that is working correctly with the ethernet connection, and monitor its network adapter settings from the “Network and Internet” option in Windows Settings and then from going into the “Status” option. The IP Address and the DNS address that it is using should be listed there, enter this information in its place and you should be able to get your ethernet back to work.

7. Now, double-click “Internet Protocol Version 4 (TCP/IPv4).”
8. Confirm that the “Use the Following DNS Addresses” radio button is selected and click “OK.”

   Note: Enter the same information that we obtained from the sixth step.

9. Now, close all remaining windows to return to the desktop.

Method 19: Decrease Your network adapter’s power output

The network adapter allows the device to communicate over the local area network (LAN), connecting to the internet or to other computers. Some computer geeks reported that they were able to get around this problem by reducing the power output of their network adapter, therefore, follow the steps throughout to get rid of this problem:

1. Press “Windows” + “R” to open the Run prompt, type in “Devmgmt.msc” in the run prompt and press “Enter” to launch the device manager.
2. Double click on the “Network Adapters” panel to expand it and right-click on the network adapter that your computer is using.
3. Select the “Properties” option to launch the network properties.
4. Navigate to the “Advanced”
5. Under Property, locate the “Power Output property” and click on it to select it.
6. Open the dropdown menu under Value and change it from 100% to 75%. If you are also going to be using an external monitor while your laptop is docked, change the value to 50% instead of 75%.
7. Click on “OK”, close the Device Manager, and restart your computer. Now check whether or not the issue has been resolved once your computer boots up.

Method 20: Disable Energy Efficient Ethernet for your network adapter

Energy-Efficient Ethernet (EEE) is a set of enhancements to the twisted-pair and backplane Ethernet family of computer networking standards that reduce power consumption during periods of low data activity. Hence, to reduce the power consumption of modem at the idle state and get rid of the Ethernet problem disable energy-efficient Ethernet by following the steps indexed below.

1. Press the “Windows Logo key + X” to open the Menu.
2. Click on “Device Manager” in the menu to launch the Device Manager.
3. In the Device Manager, double-click on the “Network adapters” section to expand it.

5. Navigate to the “Advanced” tab.
6. Under Property, locate the “Energy Efficient Ethernet” property and click on it to select it.
7. Open the dropdown menu under Value and change it to “Disabled” or “OFF” whichever applies in your case.
8. Click on “OK” and close the Device Manager.
9. Restart your computer and When your computer starts up, go ahead and check whether the issue still persists.

Method 21: Enable QoS Feature

You might be able to solve this problem by enabling the QoS feature. This feature is in charge of limiting your network speed, but a couple of users reported that the issue was resolved after enabling QoS on their router. To do this, you need to open your router’s configuration page and enable QoS. We have to mention that QoS is an advanced feature, so it might require some configuration before you can properly use it. It’s also worth noting that this feature might not be available on your router, so be sure to check your router’s instruction manual for more information. In order to login to your router’s admin panel:

1. Launch your browser and type in your IP address in the address bar.
2. In order to find our IP address, press “Windows” + ” “R” to launch the run prompt. Type in “CMD” and press “Shift” + “Ctrl” + “Enter” to provide admin permissions. Also, type in “ipconfig/all” in the cmd and press “Enter”. The IP Address that you have to enter should be listed in front of the “Default Gateway” option and should look something like “192.xxx.x.x”.
3. After entering the IP Address, press “Enter” to open the Router login page.
4. Enter your username and password in the respective categories on the router’s login page both of which should be written on the back of your router. If they aren’t, the default values should be “Admin” and “admin” for both the password and the username.
5. After logging in to the router, look to configure the QoS settings as mentioned above and check to see if configuring it fixes this issue.

Method 22: Connect USB to Ethernet Adapter

A USB to Ethernet adapter is a device that is capable of connecting a USB port to an Ethernet cable. USB to Ethernet adapters allow the users to connect multiple devices together via an Ethernet cable which is generally shorter and less reliable. USB to Ethernet adapters rely on Plug and Play technology that allows a user to simply plug the device into any USB port and then connect an Ethernet cable to it. If you are facing the Ethernet port problem then this adapter might be able to do the job for you.

Method 23: Remove any USB devices from the ports below the Ethernet port

If you have any USB devices connected to the USB ports located directly below the Ethernet port, remove these devices, and see if that resolves the problem for you. While it may sound a bit peculiar, something as bizarre as having one or more USB devices connected via the ports located below the Ethernet port is the culprit behind this problem for many people.

Workaround: If you’re sure that there’s nothing wrong with the Ethernet connection, you can check other places like the ports on the router. If the Ethernet port being used is not working or damaged, you will be unable to connect to the router. As for the Ethernet port not working cause, unplug the cable and plug it into another port to check whether the issue still appears.
