Ethernet not working - no eth0 device listed

**cmt29uk** · 01-Jul-2022, 11:20

Hi, I'd like some help getting ethernet working on a laptop. Here are the details I know. Please let me know what further information would be helpful:
Laptop is dual boot with Windows 10 and both wireless and ethernet functioning in Windows so hardware is fine.
Original installation was Leap 15.2. Upgrade to 15.3 was done via zypper.
Can't remember if ethernet was working under 15.2 but I think it was.
Wireless works fine in 15.3 but when ethernet cable plugged in, there are no lights and Network Manager does nothing.

Please let me know what further info is required to diagnose problem. Thanks.

Ethernet Cable defect?
Or not plugged in?

The ethtool utility can be useful here...

Code:

/usr/sbin/ethtool eth0
