Authentication problem of Win10 machines with cisco access points AIR-AP1242AG-E-K9

[mnice]

Hello

I hope everyone's doing well.

I have access point cisco AIR-AP1242AG-E-K9 (very old) the problem is that I have machines under Win10  which do not want to connect to Wifi, they can be recover the address from the DHCP but not access to Internet and others connects after a moment it's disconnected.

I had this problem before when the APs were in WEP authenrification, I modified the configuration in WPA2 - AES worked for a few months and now I have the same problem again.

Do I need to update the IOS? I can't do that, the APs are end of life (IOS not available)

Or change the configuration again, I don't know how to do it.

Or change access point.

Current version of AP is :  12.3(7)JA1

Thank you in advance for your usual support.

Regards.

> Or change access point
Obviously check that Windows drivers are up to date.
