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.

 

My Ethernet card doesn't connect to my router, but does to my laptop?

My desktop stopped connecting to the internet today. It has an Ethernet adapter, which is built into the motherboard, and no Wi-Fi functionality.

I started by ruling out faulty cables, by testing the Ethernet connection with my laptop (with wi-fi turned off entirely), which worked properly.

I reset the router to default settings, with assistance from my ISP, Bell, to no avail.
Next, I tried to use netsh winsock reset and netsh int ip reset, to no avail.

In frustration, I tried to bridge a connection from my laptop's wi-fi through its Ethernet adapter to my desktop. Surprisingly, this worked, and I can navigate properly on the desktop and laptop at the same time.

I tried to reinstall the driver for the desktop's Ethernet adapter. It continued not to work without using the bridged connection through the laptop, both with the default driver and the one provided by Windows' automatic update.

I'm not sure what could be causing this issue, and I haven't found any other suggested steps in my searches.

In short, my desktop's Ethernet adapter does not work when connected directly to router, but works when connected to laptop using a bridged connection.

 

Laptop adapter died

As a fun fact, some laptop adapters do interchange (old IBM Thinkpad adapters are actually a cheap and popular replacement for some Panasonic toughbooks because the specs are identical), but you should NEVER assume they do simply because of a physical fit!

Most laptops list the voltage and current on the bottom panel or by the plug. All adapters should as well if they are UL listed. Check both and don't plug it in unless they match! Even then, the best bet is ALWAYS the original adapter.

So yeah, hope you didn't do more damage than just the AC adapter is all I can say.
