Hi. I'm David, and I'm happy to help you.

It is necessary to investigate to understand the reason for this behavior.

Please share a screenshot of the network adapters in Device Manager.

Press "Windows + X" and select "Device Manager";
Click on the "View" menu and select "Show hidden devices";
Expand "Network adapters".

Also, share a screenshot of your system information.

Press "Windows + R", type msinfo32 and press Enter.

Maximize the window and use the screenshot tool.

Looking forward to your reply.

Sorry. You went to the wrong place. I suggested checking the network adapters in Device Manager, not Control Panel. Follow the steps in my answer above.

By using Device Manager and selecting the option to show hidden devices, I'll be able to get an idea of what happened and determine the next steps.

Looking forward to your reply.

Thanks for the screenshots.

Did you enable the "Show hidden devices" option in the "View" menu?

I ask this because no Ethernet adapter is displayed in your screenshot. It is as if Windows had never seen an Ethernet adapter on this PC. In other words, as if the PC didn't even have one.

I looked up the specifications for the Aspire AL15-41P online and found that there are several variants, some of which do not have a built-in Ethernet port. Is that the case with your Aspire? Are you using a USB Ethernet adapter?

Looking forward to your reply.

Thanks for the clarifications.

I'll help you identify what the problem is.

If your Aspire really doesn't have a native Ethernet port, you really have to use a USB adapter.

What is the manufacturer and model of the USB adapter you are connecting to your PC?

After connecting the adapter and the Ethernet cable to it, does any light turn on on the adapter?

Also, with the USB adapter connected, open Device Manager and see if there are any devices labeled "Unknown device" or with warning signs. Click the arrow to the left of each category icon to expand it and see the devices it contains.

Share a screenshot of what you find.

Looking forward to your reply.

Sorry for the delay in reply. I've been offline.

Thanks for the clarifications.

That's unusual. Windows typically recognizes connected hardware immediately. A standard Plug-and-Play adapter should auto-install and appear under Network adapters. If the driver is missing, Windows should still detect the hardware and flag it as an Unknown Device or show a warning icon.

If the device does not appear in Device Manager at all, there are two likely causes:

Power but no data: The adapter is receiving power, but its data lines are failing to communicate with the PC.

USB port issue: The computer's USB port is faulty or dirty, preventing a proper connection.

Here are a few quick tests to narrow down exactly where the connection is breaking:

Plug a different USB device (like a flash drive or a mouse) into that same USB port. Does the PC recognize it?

If you have access to another computer, try plugging the adapter into it. Does it work there?

Open Device Manager, then plug and unplug the adapter. Watch the screen closely; does the list briefly flash or refresh? (Even if no new device appears, a quick flash means Windows is at least detecting physical movement in the port).

Please share the results to help determine the next step!

Feel free to ask any questions you may have.
