I had asked the question in this way before but it was not successful + I have some information to add.
I have an Asus Rog Strix Gl703GM laptop with Windows 10 home.
I see all available networks.
However, if I want to connect to the Internet via Wi-Fi, the following happens:
(Password is entered correctly)
The network key is not correct. Please try again.
(Password is entered correctly again)
No connection to this network possible.
If I plug in a LAN cable at home, it also connects to the WLAN but the connection then breaks again over time.
I have already reset the PC 2x (1x Factory 1x the faster version)
I reinstalled every tip with adapter, entered commands in the command line & & & tried and nothing helped… I'm really desperate and now I'm back in my student apartment without access to a LAN cable.
I'm grateful for every suggestion!
Is a Mac filter activated in the router? Turn this off for testing.
Did you connect the power adapter to the laptop? If it has too little juice, some things will no longer work.
Can your adapter handle encryption of the router? If necessary, switch this off or use a lower level.
And how does the device react to a connection to a hotspot? Turn on hotspot on your mobile phone and connect to it. Then does it work?
Do you have security software or firewalls installed or are you only using Windows Defender?
Buy a WLAN stick, AVM or TP-Link and establish the WLAN connection over it. Deactivate the internal WLAN adapter beforehand in the device manager.
Register again.
I have already tried Handy Hotspot, reacted in the same way as described above. No security software is installed, the internal Windows is used. 1x I was successful and everything worked again when I uninstalled all adapters, but after restarting the same problems. Now de and reinstalling does not help. I guess it could work with an external adapter but due to the circumstances of this time as a student I have to pay attention to every cent…
Windows creates a so-called WLAN profile for each WLAN network.
Windows stores all necessary settings (encryption, IP configuration, DNS, gateway and much more) for the respective WLAN in this profile.
If these settings are turbulent or different in the meantime (changed due to encryption or frequency band, router update, driver update, …) it may be wrong.
My proposition:
Delete the profile for your Wi-Fi in Windows and connect to the Wi-Fi freshly (you need the Wi-Fi key, because you know that).
So: open the properties of your Wi-Fi network and press the "do not save" button. Then freshly connect to your Wi-Fi (remember, Wi-Fi key is required, hopefully you will have one). Very important! You absolutely have to press the "do not save" button in Windows 10 so that Windows really deletes the WLAN profile completely!

No matter which router or cell phone hotspot the problems are present. Power supply was always connected…
If a connection can never be established, the adapter in the laptop seems to have a problem.
