Hi, I have had huge network problems over the past few weeks. I've looked through similar posts, but nothing has helped.
I'm not sure exactly what the problem is but I think it's the network adapter. It sometimes works for a couple of minutes, then it disappears entirely from device manager. Quite often though it shows up once I click "show hidden devices". I have tried uninstalling many times, but now it doesn't even seem to be installing. During installation a pop up says "The device may not be present or could have been ejected from the system. Insert or reinsert now." Then it seems to continue successfully, but nothing happens, it doesn't show up in device manager.
I'm in dire need of help being a student in a foreign country. Please let me know if any photos or something is required.
Thank you!

This is for a laptop, Asus X540LA, the recommended driver on the Asus website is a Qualcomm Atheros something, that is the one I've been trying to reinstall, but it's not working. :(

For about 5 hours today the Internet was working. But then it stopped again. There's the red cross in the bottom right corner.
And in device manager, the network adapter is not highlighted, meaning it's not active and only shows when I click "show hidden devices".
Why is this so spastic!

I think you are right. When it's not highlighted, the device status says "Currently, this hardware device is not connected to the computer.(Code 45)"

I don't know why this should happen, the laptop isn't even 3 months old. Thank you for your advice, but I have no idea how to do any of those. I don't have any experience with troubleshooting. I've emailed Asus, not sure if warranty is international though. If I were to reset the card as you say, how would I go about it?
Honestly, I really appreciate your help, thanks.
