Wi-Fi connection setting changed?

I changed the security setting of my rotator from WEP to WPA2 with AES and since then I can no longer connect to my laptop, despite the request that I enter my security key, the PC then says that no connection to this network is possible.

How do I restore the connection?

Everything is possible with the mobile phone.

The WLAN module of the computer can also WPA2? If he is very old, it can also be that it does not work.
So you enter the key and it will not work?

You take the right network?

The laptop is from 2016. I assume that the WPA2 can. Yes, I already use the right network. The diagnosis has just spat out, but the security types do not agree. At least Eich knows that I did not delete the internet.

OK. I have just checked my network adapter.

It is not WPA2 compatible. This is the question lapsed, but thanks for the answer.

For a laptop from 2016? That's really blatant…
