Network adapter not detected

[fred2028]

I have a network adapter in my laptop, but recently it's not being detected. I've tried reinstalling its driver from Acer's website and restarted, but no luck. Right now I can only connect via Wi-Fi and not ethernet. The normal adapter is called Atheros. I have also tried Windows Update. Anyone have any idea what's wrong?

Are you saying that your ethernet adapter (or controller) is not detected in Device Manager?

If so, are there any unknown devices or warnings or errors?

Most laptops have s switch on the front to turn it ON/OFF, by chance has yours been turned off?

This is an ethernet card, not wireless. And no, it doesn't show up in Device Manager. I have 1 unknown device but that's my finger print reader.

Check in the BIOS to see if it somehow became disabled. If not, it is in all likelihood dead.

How do you check in BIOS?

When you turn the PC on or Restart tap the F2 or Esc or whatever key on your particular PC allows you to enter the BIOS (Setup). When you get there you look around. The required key is shown briefly on the screen, and may be in your documentation.

OK looked in there, nothing.

There are 2 lights around my ethernet port. When I plug a cord in, the yellow 1 flashes (left) but the green one (right) doesn't turn on.
