Windows 10 losing Wifi connection

[illuvattarr]

Recently, I moved my desktop PC to another place and bought a TP-Link AC1300 T6E PCI-E wifi card. But since then, I'm having problem with my Wifi connection on the desktop.

It seems that (at random moments) my PC with Windows 10 just loses the wifi connection and I can't see both my 2.4 and 5 Ghz wifi networks anymore. Disabling the network card and enabling it again doesn't work even though other wifi networks are visible and my own wifi network is still visible on my phone/laptop and working perfectly. The only thing that (temporarily) fixes it, is rebooting my PC.

It does seem that the issue happens at random moments, but I found 1 trigger to it; when copying a large file from my network attached storage to my PC, about a couple minutes in, the issue happens again and my wifi networks are undetectable.

Things I've tried:
- Disabling 'Allow the computer to turn off this device to save power' in the power management properties of my network card.
- Setting all of my general power management settings in control panel to maximum performance.
- Completely removing and reinstalling the network card.
- Completely removing and reinstalling the network card again with the latest official windows 10 drivers.
- Searched for the Reg key HKCR\CLSID{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f but it doesn't exist.
- Executed the following command in cmd.exe: netcfg -v -u dni_dne


What could be the problem here?

During a large file copy things inside your PC could be heating up. Especially the network adapter. Something expands and connectivity is affected.

Open up the case and do some test large file copies. Check around the network adapter to get a sense of temperature. See if the network adapter gets hotter after some time of use.

Clean out dust and debris. Reseat everything and check all plugs and connectors.

Could also be an antenna problem: reception and/or transmission. Does not take too much hit some threshold and performance plumments. May be triggered by heat.

Try antenna extensions to raise the antennas up from behind the PC. Or test by temporarily setting the PC up higher. That may also help with cooling.

I doubt it's a hardware problem, since I can still see and connect to other Wifi networks. It just doesn't show my own anymore.

Have you tried using other channels?

Is your NAS box wired or wireless?

I tried setting other wifi channels in my router but to no avail. Also cleaned up my pc from the inside and removed dust, but still losing connection when transferring large files.

My NAS is wired to my router.

Taking a step back:


"- Completely removing and reinstalling the network card again with the latest official windows 10 drivers"

Download and install the network wireless adapter drivers from TP-Link.

Provided that I have correctly identified your wireless adapter the following link should help:
