Windows 10: Have to reboot my Laptop to detect a ethernet connection

Hello


I have an issue where if I plug my ethernet cable into my laptop, it doesn't detect...

The only way for me to get a connection through the ethernet cable is to restart my laptop, and then it picks it up...

Ethernet connection/port on my laptop

Thanks for the suggested solution which I tried. My feedback:

• Update download was completed but installation did not complete and the message popped up that stated that update is not compatible and cannot be installed.

Info sought in your mail is as follows:

• Which build and edition of Windows 10 is installed on your computer?
  • Window 10 Pro
  • Version 1709
  • OS Build 16299.192
• What is the make and model of your laptop?
  • Dell Alienware
  • 15" Laptop
  • System 64 bit os x64-based processor
• Are you experiencing the same issue even when you are using another Ethernet cable?
  • yes, tried different cables
  • (also same ethernet cable & connection works on my mac notebook)
• Have you made any changes to your computer setting before this issue occurred?
  • Can't say with certainty about changes, if any, made. Normally i don't fiddle with the laptop systems.
  • ethernet port was working just fine and suddenly became dsysfunctional about two weeks back.
  • Checked Network adapters in the device manager which highlights Killer E2200 Gigabit Ethernet Controller with a yellow mark. Also checked network adapter driver which states that installed driver is the latest.

Hi,



Thank you for posting your query on Microsoft Community.



We would like to ask additional information that will help us in resolving the issue.

• What kind of computer are you using? Is it a desktop or a laptop?
• Did you make any recent changes to your computer?
• Have you tried troubleshooting the issue by yourself? If yes, what were the steps you have taken so far?

I would suggest you to try the following and check:

• Verify that the cable connects the modem to the wall jack is connected securely.
• Verify that the cable connects the computer to the modem is attached securely at both ends.
• Restart the router/modem.

Follow the steps and let us know if it helps.

 

laptop can't find wifi but connects with ethernet cable

Please try these troubleshooting steps that may help.

1. Make sure the router SSID broadcast is on.
   
2. Change the wifi channel to see if it resolves the problem.
   
3. Enter the SSID and WPA2 password manually and see if the laptop connects.
   
4. Temporarily turn off the encryption.
   
5. We go into device manager & check updates for wifi drivers, we may need to simply update the driver.
   
6. We go to Settings - Network & Internet - Status - Change Adapter Options, then right-clicked 'Ethernet' and disabled it. We do the same with wifi. Then we (with Ethernet still disabled) enabled wifi. It should re-connect to your wifi after a while.
   
7. We have to disconnect our Ethernet cable from our laptop and follow the steps:
   Start>Control Panel>Network and Sharing Center>Manage Wireless Networks and remove all wireless connections by right click on it and select Remove network from the drop down menu. After doing this, close the windows and scan for the wifi networks.
   Click on the available network and select connect. After a while, we will be asked to give a password for our wifi connection. Type the password and click on connect button. And now will be connected to our wifi network via wireless.
   
8. First is to disconnect the internet cable from the laptop then uninstall/reinstall the wifi adapter.
   Go to Device Manager and uninstall the wifi adapter.
   Once uninstalled, reboot the laptop and it should reinstall the driver automatically.
   After the reboot do try connecting to your wireless network again.
   If all these will not work, do also make sure that the wireless adapter is enabled. Depending the model of your laptop there should be key combinations on how to enable/disable it.
