I have just upgraded a PC from Windows 7 to 10.  Everything worked well apart from now the Network Card is not found?  It doesn't appear in Device Manager and I cannot get the ethernet connection to work?  It worked fine downloading the W10 files but since the installation finished - nada!

 

Anybody help?

If the computer has UEFI there may be a setting that enables/disables LAN. Check that. 

 

What is the make and model of the computer? Some LAN's NICs do not show in Device Manager unless a chipset driver is installed.

Thanks John,

 

The PC was made as a custom job and purchased online about three years ago.  To access UEFI (if it has it) do I get into in the similar way to BIOS, at satrtup?

UEFI is firmware used on newer computers that replaces the older BIOS. I don't know your key press but enter UEFI or BIOS depending on your MB. Look for any setting  enabling your NIC.

 

Download CPUz. Run it and under the Mainboard tab list the Chipset and Southbridge. It's possible Windows 10 does not have drivers for your NIC chipset and therefore is not detected. CPUz should also show the MB maker and model number. Post that also.

Missing NIC and touchpad drivers is a common problem for some who upgrade to 10.  You need to find the details for your NIC and install the Windows 10 driver for it.  If you can't, you can always buy a USB one, plug it in, and install the driver that comes with it.

 

 Good luck.


Make regular full system backups or you'll be sorry sooner or later.
