Hello,

Today I lost the ethernet connection to my desktop. It has never happened with the router in the last so many years. Rebooted the PC, rebooted the router, disconnected all other hardwired devices, and updated drivers using Support Assist. Nothing is working. The LEDs at the data port site are solid orange at the top and solid amber at the bottom. Disabled the energy efficiency of the network adapter. Changed the cable. Please suggest a solution. Thanks.

Hello,

That RJ45 cable looks damaged to me try that cable in another device if you can if the connection is working on the other device you know it is not the cable causing an issue

Hi

Dis-connect the cable.

Try a coupla commands .....

C:\>ping 127.0.0.1

C:\>pathping 127.0.0.1

C:\netsh lan show interfaces

C:\netsh lan show drivers

C:\ipconfig /all

I dont have ethernet so cannot give too much detail.

C:\>pathping 127.0.0.1

Thanks, ann_droid.

I got exactly the same results as you mentioned.

Not sure what to make of it.

Thanks, confuseduser43

I have already swapped the cable for a new one - still no connection.

Hello,

Press the windows key +r and type msdt.exe /id NetworkDiagnosticsWeb if that doesn't help i found this does it help ?.

Thanks confuseduser43,

I did try the suggested solution. But in the properties, I couldn't find the options listed except ARP offload. I have attached my screenshot.

Hello everyone,

Today I connected the ethernet cable to the USB port at the front of the XPS through a Gigabit Ethernet Adpater. I got the same speed the way I was getting through the ethernet connection before it dropped. This confirms that there is nothing wrong with the router, and data cable. The LAN port on my XPS is not working.

Hello,

The screenshot you posted is from a wifi adapter but ethernet is a wired connection and since you already found there is no problem with your router or cable there is one more thing you can try

press the windows key +r and type ncpa.cpl in the window that opens right click your ethernet connection it should be named "Ethernet" or "Local Area Connection" choose disable wait a minute and then enable again.
