The Intel 8260 is a good adapter.

  1. The next time it is working, update the driver - there are new updates for it.

  2. When it disappears, you cannot see it in Device Manager. If you are adept with small things, try re-seating the card (it plugs into a socket inside the computer). Ask a local computer store to do this if you would rather not.

  3. If re-seating fails, then the card is likely defective.

  4. You said later a USB wireless card works and the USB card can work even if the internal card does not. If you suspect Viruses (viruses do not normally kill a card) do a full scan with Windows 10 Defender

  • Hello, Thank you For your help Well I will try to re-seat the Card but I don't think the problem is in the card I think ( I am not sure if this even exists ) that there is a Virus Which damages my Adapter driver Well, When I opened my PC today, I disabled the card driver and I plugged an WIFI-USB ( I don't know how to call it ) , and installed it's driver it worked properly for some while, then I tried disconnecting from my router and connecting to another, then everything stopped again. Is it possible that a virus do something like this ? thank you,and sorry about my language

  • If the USB wireless works, then main hardware is OK. And the USB card can work even if the internal card does not. If you suspect viruses , do a full scan with Windows Defender

  • I tried about 3 or 4 anti-viruses But Everything looks good , no malwares, no Viruses, Nothing at all. I forgot to mention that the problem occurs also If I try to turn on airplane mode. or if the problem occur the airplane mode stops working also.

  • I am fairly sure the internal card has a hardware issue.

So after all I wasn't able to find where the problem is coming from. I end up with resetting my Pc (Windows 10 -- Reset this PC (keep my files) --) and the problem is gone now, everything work properly. Thank you.
