Windows 10: Change network authentication method while disconnected.

Recently, after mistakenly changing settings over work wifi, I'm no longer able to use the network or sign in anymore.After accidentally changing the network authentication method in network adapter settings, wifi now asks for a sign-in I'm normally just able to connect without signing in. When I enter my credentials I'm prompted with "can't connect because the sign-in requirements for your device and the network aren't compatible. Contact your it support person."My understanding is the wifi normally operates on a certificate-based system. I can't just change the settings back,&nbs

Unable to change network authentication method

Hello,

I have a problem where I'm unable to change authentication method and therefore can't connect to the internet through ethernet adapter.

Basically, I want to change my authentication method to SecureW2 TTLS because other methods don't work with my ISP. Screenshot showing the problem:







After clicking OK, I get this error (The changes to Authentication settings could not be saved). I also get the same error if I for example try to uncheck "Enable IEEE 201.1x authentication" or if I try to change anything under Authentication tab.

Reinstalling Windows solved my problem a week ago, but now this error is back and I don't want to reinstall Windows again.

Things I've tried:

Reinstalling adapter

Updating adapter drivers

Restarting TCP/IP via netsh

Reinstalling SecureW2 (I have installation program for this authentication method)

Troubleshooting network

Restarting network

Probably couple more things I already forgot

Any solutions?

I did as asked.

Enabled Administrator account

There was a short setup as if I just entered desktop for the first time

Tried changing some setting in Authentication tab and got the same error
