Problem with D-Link DWA-556 Xtreme N

[zsyntex]

Hi guys, I've a problem with this PCIe Network Adapter. Everytime I reboot my PC or boot up from stand-by, I've to reconnect it to my WiFi that it's saved (I don't need to enter the password again).
That's annoying, because sometimes it won't happen (stay connect) and other times no.

What should I do? I've always had this problem, on Windows 8.1 and Windows 10.
I've a i5-4670K, AsRock Z87 Ext and Windows 10 on last build. (1803)

Does the following link match your wireless adapter?

Ensure that any wired adapters (e.g., motherboard) are disabled.

Have you tried angling the antennas in different directions per the User Guide?

Interference: You might need to change frequency and channels - especially if in an enviroment where there are other wireless devices.

Consider an antenna extender to move the antennas up and away from the back of the computer.

Yes, I've angled the antenna a lot of times. I cannot change the channel, as it uses the same used by the router. Frequency is only 2,4GHz, not 5GHz. (AliExpress wrote wrong info :/ )
I see a full-power WiFi, so it isn't a WiFi range problem.

Okay - other suggestion:

Check that all antennas are fully and firmly screwed on.

Power off, open the case and inspect the adapter to ensure that it is fully and firmly in place.

Inspect the card with a bright light to look for any signs of damage or electrical problems (brown or blackish components).

Next step, in my mind, would be to go to D-Links website, download, reinstall, and reconfigure the adapter's drivers.

That could be done, if you wish as the first step but would be moot if there is a physical problem.
