Windows 10: Only PCs can't connect to 5GHz Wi-Fi - Windows 10 AC600

Current device: Asus X756UX-T4244T
Wi-Fi adapter: FRITZ! AC430 and TP-LINK Archer T2U AC600
Router: Unitymedia Connect Box
( All drivers updated )
Hey,
after seeing how big the speed difference between my 2.4GHz and 5GHz is I tried connecting every device with 5GHz. My iPad and S9 connect with 5GHz instantly without any problems. When I try to connect with any PC after about 5 seconds of loading my Wi-Fi adapter (AC 430) disconnects, then after like 3 seconds the adapter reconnects and it says "cannot connect to this network". Exact same thing with the other adapter and with other PCs.
Connecting to 2,4GHz is working 100% fine. When I use the same SSID for 2.4G and 5G it automatically connects to 2.4G even tho I have 5G as preferred in Windows.
I've really tried everything I could find already: Tried 2 different Wi-Fi adapters, they ALL support 5GHz and 802.11ac - Tried 3 different PCs (all Windows 10), reset my network settings, drivers, password is 100% correct, restarted router multiple times, tried all USB ports, changed SSID so 2.4G and 5G are not the same anymore, tried every channel < 50 and all Wi-Fi standards, checked all settings for the adapters + windows, disabled firewall, enabled high-performance mode on my notebook, unplugged everything....

This is very very weird because all my devices except PCs connect to 5GHz. When connecting with a PC the Wi-Fi adapter resets during the process and it fails to connect. It feels like they are being blocked by something. Since my 3 PCs don't connect and the process looks exactly the same (Adapters reset/disconnect while trying to connect) I'm sure it's not a software issue. The adapters are also brand new so they're not the problem. What's the difference between a mobile/iPad Wi-Fi card/adapter and a PC Wi-Fi card/adapter? Why can my mobile devices all connect to 5GHz but my PCs can't? Has anyone ever fixed or experienced this? What else could I try?

Thanks in advance *Wink

Windows 10 stop automatically connecting to random new wi-fi networks


Hi,

I have searched a lot, but all the tutorials I found only explained how to not connect automatically to a known wi-fi network or how to disable wi-fi sense... but this is not what I am looking for...

PROBLEM:

• When my laptop (Windows 10 Pro X64) is not connected to a network and the wireless adapter is on, it will automatically connect to any random new unsecured wi-fi network... The only way I have now to avoid this is to disable my wi-fi adapter.

UNUSEFUL TUTORIALS I FOUND ON THE INTERNET:

• How to manually uncheck the option for a particular wi-fi network not to connect automatically in Network Properties. This is not what I am looking for. This would suggest that everytime I power my computer. I would have to manually go through all the available wi-fi networks and unclick them all...
• How to disable Wi-Fi Sense. This is not useful, because I don't even have a Wi-Fi sense option in my computer where the tutorials say it should be.

EXPECTED BEHAVIOR:

• I am looking for an option to tell my computer to stop connecting randomly to unknown wi-fi networks like an hyperactive, reckless idiot.

PERSONAL COMMENT:

• Honestly, why would any respectable company think that it could be somewhat wise or secure to do this... Anyone's computer could just randomly connect to any hacker's wi-fi network without the user even knowing it...

Any solutions would be greatly appreciated! Thanks!
