Summary
After you apply the Windows 10 November Update (Released on November 10, 2015) to a Windows 10 device, you cannot connect to a Wireless WPA-2 Enterprise network.
Cause
In the Windows 10 November update, EAP was updated to support TLS 1.2. This implies that, if the server advertises support for TLS 1.2 during TLS negotiation, TLS 1.2 will be used.
More Information
To configure the TLS version that EAP uses by default, you must add a DWORD value that's named TlsVersion to the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RasMan\PPP\EAP\13
To add these registry values, follow these steps:
- Click Start, click Run, type regedit in the Open box, and then click OK.
- Locate and then click the following subkey in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RasMan\PPP\EAP\13
- On the Edit menu, point to New, and then click DWORD Value.
- Type TlsVersion for the name of the DWORD value, and then press Enter.
- Right-click TlsVersion, and then click Modify.
- In the Value data box, Enter 0xC0
- Exit Registry Editor, and then RESTART the computer
